REMKO VRS Safety information
Unit description
Operation of the heaters must always take place in compliance with the local building and fire protection regulations and regulations of the employers‘ liability insurance associations.
The heaters are stationary, directly fired hot air heaters with heat exchanger and chimney connection. The heaters can be fired with fuel oil EL, diesel fuel and liquid or natural gas.
The heaters were subjected to extensive material, functional and quality inspections and tests prior to delivery. However, the heaters may constitute a hazard if used by untrained personnel, improperly or not for the intended purpose. The following information must be observed: ■ The heaters must only be used by persons who have been trained in its operation.
■ A protection zone of 1 m dis���� tance must be kept free. ■ The air intake grilles must always be kept free of dirt and loose objects. ■ Never insert foreign objects into the heater. ■ ��������������������������� The heaters must not be exposed to a direct jet of water, e.g. high-pressure cleaning equipment, etc.
■ The heaters must be installed and operated in a manner that excludes any risk to persons through radiated heat and the risk of fire.
■ Never allow water to enter the inside of the heater.
■ The heaters must only be installed and operated in rooms if they are supplied with a sufficient air volume for combustion. If this cannot be ensured, the burner must be supplied with fresh air from outside via a separate air intake system.
■ Portable fuel tanks must only be installed and used in compliance with the technical directives for flammable liquids „TRbF 20“.
■ The heaters must only be installed on a flame-retardant surface. ■ The heaters must only be attached to constructions designed to the take the weight or to ceilings of flame retardant materials with sufficient load bearing capacity. ■ Attachment must take place using suitable anchors to be attached to the heater. ■ The heaters must not be installed and operated in locations where there is a risk of fire and explosion. ■ The heaters must be installed outside traffic zones, e.g. also the operating areas of cranes.
4
■ All electrical cables of the heaters must be protected against damage (e.g. also from animals).
Note Only type tested hot air heaters with forced-air oil burners complying with DIN EN 230 and DIN EN 267 must be used.
ATTENTION Where delivery from the factory takes place without fan burner and a different make of burner is used, the suitability of the burner for the particular type of hot air heater must be ensured.
The heaters are designed exclusively for operation with separate fan burners in singlestage operation. Standard two-stage fan burners can also be used to prevent the formation of condensation during start-up (as starting relief) in the partial load range. For reliable discharge of the exhaust fumes via the roof, the heaters must be connected to a suitable chimney system. The heaters are provided with standard single-stage, low noise/ low maintenance radial fans and mounted and electrically wired switching and control units. The heaters are built to give many years of efficient service due to their robust design and the use of high-quality materials. Further plus points include quick and easy installation and ease of servicing. The heaters comply with the basic health and safety requirements of the pertinent EU regulations and are easy to operate. Note The heaters are not suitable for domestic heating or similar.
Heater applications
Mode of operation
The directly fired hot air heaters supply instantaneous heat. The heaters are designed exclusively for industrial and commercial use. The heaters can be fitted with inlet and outlet air ducts with appropriate dimensioning.
After switching on the heaters by setting the switch to the „Heat“ or „I“ position, the forced-air burner starts.
In the event of irregularities or extinguishing of the flame, the burner is shutdown by the burner relay and interlocked.
The „Burner“ indicator light on the control box lights up for control purposes in the case of the 400V heater types. The combustion chamber with heat exchanger is now heated.
The fault indicator light of the burner relay and the „Burner“ fault indicator light on the control box light up in the case of the 400V heater types. Restarting can only take place after manual release of the burner relay.
There are generally no operating restrictions with regard to the site of installation. Heater applications also include: ■ Heating workshops ■ Heating warehouses
After reaching the set temperature, the supply air fan switches on automatically. The „Fan“ indicator light on the control box lights up in the case of the 400V heater types. Hot air is blown out.
The safety temperature limiter (STB) interrupts the burner function on overheating. Manual release of the STB can take place only when the heater has cooled down.
When using a room thermostat, the described sequence is automatically repeated depending on the heat requirement.
The fan motor in the case of the 400V heater types is monitored by means of a thermal overcurrent relay.
All heater functions take place fully automatically and are reliably monitored by means of the triple function combination controller and burner relay (integral part of the force-air burner).
On motor overload, operation is interrupted by the relay and the red „Fan“ fault indicator light on the control box lights up. Release is only possible after resetting the relay in the control box.
■ Heating exhibition halls ■ Heating fair halls ■ ������������������������������ Heating light-weight construction halls ■ Heating showrooms ■ Heating in horticulture and agriculture
After switching off the heater via the switch or room thermostat, the supply air fan continues to run until the combustion chamber and heat exchanger have cooled down and subsequently switches off automatically.
ATTENTION The heaters are intended exclusively for industrial and commercial use. They are not intended for domestic heating or similar.
ATTENTION The heaters must never be disconnected from the mains supply before the cooling down phase has ended (except in emergency situations).
NOTE Before releasing the burner relay or overcurrent relay, the cause of shutdown must always be determined first.

Controller shown without housing cover
The three functions of the combination controller: 1. Fan controller (TR) Controls the fan on and off function. The switching point can be set via the „TR control lever“. Set value about 40°C 2. Temperature monitor for the burner (TW) The temperature monitor limits the air outlet temperature. The switching point can be set via the „TW control lever“. Set value about 80 – 85°C
3. Safety temperature limiter (STB) The STB controls the temperature monitor. Switching point permanently set to 100°C. A restarting lockout prevents the burner from being restarted. The reset button (RESET) must be actuated manually from outside with the housing cover closed. Note When replacing the triple function combination controller, only a REMKO original replacement must be used!
Attention To prevent the operating temperature being exceeded again, the operating conditions of the heater must be checked prior to resetting/releasing the STB.

Attention safety devices must not be overridden or blocked during heater operation.
Triple function combination controller The triple function combination controller has a sensor monitor and is cold resistant to -20°C. The heater switches off at a temperature below -20°C and switches on again when the temperature rises. In the event of damage to the sensor or capillary tube and on reaching a temperature of about 220°C, the filling medium is drained and the combination controller switches off towards the safety side. The combination controller is no longer functional and must be replaced. For replacement of the triple function combination controller, the following information must also be observed: ■ The capillary tubes must not be damaged or bent during installation. ■ Any bending must take place only on the capillary tube and not on the sensor. ■ To ensure that the heater functions reliably, the sensors must always lie freely in the hot air stream. ■ The sensors must always be free of dust and dirt. ■ Capillary tubes and sensors must not be damaged in any way. ■ The sensors must not have contact with the combustion chamber or other metal parts. Attention Installation and assembly must be carried out carefully and professionally.
Installation instructions Installation of the heaters must generally take place in compliance with the directives of the building regulations (LBO) and the Ordinance on Firing Installations (FeuVO) of the respective federal state. The First Ordinance on the implementation of the Federal Immission Control Act (1st BImSchG) and the subsequently issued statutory requirements of the Ordinance on Small Firing Installations (1st BImSchV) must also be taken into account. Hot air heaters in particular are excluded in some respects however. Note Only type tested hot air heaters with forced-air oil burners (complying with DIN EN 267) or gas burners (complying with DIN EN 676) must be used.
Note Where delivery from the factory takes place with an oil or gas burner, separate operating instructions for the burner are enclosed.
Selection of site of installation The following must be observed when selecting the site of installation: 1. Fire protection and operational hazards. 2. Function: Room heating free blowing or with duct system. Observe pressure conditions at site of installation . 3. Operational requirements: Heat requirements, air volume flow, air circulation and outside air operation, humidity, air distribution, room temperature, space requirement. 4. Option for connection to a chimney system. Oil and gas-fired hot air heaters (also with a nominal heat output above 50 kW) may generally be installed outside heating rooms in compliance with the Ordinance on Firing Installations (FeuVo). The guidelines of the building supervisory authority for the „installation of heat generating systems“ must be observed.
Attention The heaters must be installed and mounted so that they are easily accessible for monitoring,repair and maintenance.
Attention Low or excess pressure in the installation location must be avoided as this can result in combustion problems.
Locations in which flammable substances or mixtures are processed, stored or produced in quantities liable to be hazardous in the event of ignition may be subject to exceptions if it is ensured by suitable measures that the substances or mixtures cannot ignite due to the heat generating system.
Combustion air supply A sufficient supply of combustion air must generally be ensured by the respective requirements of the building supervisory authority. Extracts from M-FeuVO (Specimen Firing Ordinance) (may vary between federal states). (1) F or non-roomsealed heating appliances with a total nominal heat output of up to 35 kW, the combustion air supply is deemed verified if the heating appliances are installed in a room with: 1. Minimum one door leading to the outside or one window that can be opened (rooms leading outdoors) and having a cubic capacity of minimum 4 m3 per kW total nominal heat output. 2. An opening leading to the outside with an internal crosssection of minimum 150 cm2 or two opening each 75 cm2 or pipes leading to the outside having cross-sections equivalent to the flow. (2) F or non-roomsealed heating appliances with a total nominal heat output of more than 35 kW and not more than 50 kW, the combustion air supply is deemed as verified if the heating appliances are installed in rooms that comply with the requirements specified in Section 1 No. 2. (3) F or non-roomsealed heating appliances with a total nominal heat output of more than 50 kW, the combustion air supply is deemed as verified

if the appliances are installed in rooms that have an opening or pipe leading to the outside. The cross-section of the opening must be minimum 150 cm2 and 2 cm2 more for each kW nominal heat output above 50 kW nominal heat output. The pipes must be dimensioned equivalent to the flow. The necessary cross-section may be divided into maximum two openings or pipes. (4) Combustion air openings and pipes must not be sealed or closed unless it is ensured by separate safety devices that the heating appliance can only be operated when the closure is open. The necessary cross-section must not be constricted by the closure or grille. (5) A sufficient combustion air supply can be verified for nonroomsealed heating appliances using a different method than that specified in paragraphs 1 to 3. For example by: A continuous pipe of sufficient cross-section connected to the burner or its burner housing leading to the outside. This cross-section must be adapted to the available suction capacity and the pipe resistances (including air inlet grille) so that perfect combustion is ensured.
Installation ■ The heaters must only be installed and operated in rooms if they are supplied with sufficient air volume for combustion and the exhaust fumes are discharged to the outside via a suitable chimney system ■ Non-roomsealed heating appliances may be installed in rooms or buildings from which air is extracted with the aid of fans or ventilation systems, etc., only if: 1. Simultaneous operation of the heating appliances and air suction system(s) is prevented by means of safety devices. 2. The chimney duct is monitored by means of special safety devices. 3. The exhaust fumes of the heating appliances are filtered via the air suction system(s). 4. It is ensured by the type of construction or dimensioning of the system that no dangerous low-pressure can occur. ■ The heaters must be installed on sturdy, flame retardant surfaces and outside traffic zones, e.g. also the operating areas of cranes. ■ The heaters must be installed and operated in a manner that excludes any risk to persons through radiated heat and the risk of fire. ■ The heaters must be installed so that they do not constitute a hazard or unreasonable nuisance, e.g. through shocks, vibrations or noise.

■ T he heaters must be installed and mounted so that they are easily accessible for repair and maintenance. ■ Operating elements whose improper operation can result in dangerous operating conditions must be protected against unauthorised use if they are generally accessible. ■ Direct suction of the outside air with the standard combustion chamber is not recommended. During installation of the mixed-air flaps (accessories), these must be connected working in opposite directions. The supplied fresh air volume should not exceed 30%. ■ The heaters must not be installed and operated in rooms and locations subject to fire and explosion. Note The heaters are suitable for the use of inlet and outlet sided accessories.
Attention Standard type heaters are not suitable for exclusive use as ventilation units.
Floor mounting The heaters must be installed on stable, flame retardant surfaces and outside traffic zones, e.g. the operating areas of cranes.
■ Where auxiliary equipment is required for monitoring, maintenance and repair, this must be provided by the operator.
Suspended heater installation For the protection of the heaters against damage in commercial locations, for unhindered maintenance and repair of the heater and burner as well as unhindered air suction and blowing, a protection zone at a distance of 1 m around the heating appliance must be kept free. This protection zone must be marked by a sign with the following inscription: Protection zone Keep free at a distance of 1m A permanent barrier for frequently accessed areas is recommended.
The heaters must only be attached to constructions designed to take the weight or to ceilings of flame retardant materials with sufficient load bearing capacity. Attachment must take place using suitable anchors to be securely attached to the heater. The requirements specified in the Section „Wall mounting“ must be observed.
Room heating Hot air heaters must only be operated in closed rooms and halls via a room thermostat.
Wall mounting Fuel supply The wall to be used for mounting purposes must be of flame retardant materials. The loading bearing capacity of the wall must be verified (reinforcements must be provided if necessary). The brackets must be firmly fastened to the wall and the heaters securely fixed to these. Sufficient free space for maintenance of the heat exchanger, burner, fan and chimney system must be provided. ■ Operating devices for the heater and fuel supply must be able to be operated from ground level.
The fuel supply must be installed in compliance with the requirements of DIN 4755 for oil-fired hot air heaters, DIN 4756 and DVGW worksheet G 600 for gas-fired hot air heaters and TRF for liquid gas.
Attention The measured pressure in the suction pipe should not exceed minus 0.3 bar; it can be maximum minus 0.4 bar.
Electrical installation Attention Electrical heater connection must be carried out by authorised specialists as defined in DIN EN 60335-1 and VDE 0116. It must be ensured that an impermissible undervoltage due to intermittent system overload is not possible. The cables used for connection of the heaters must have a crosssection of sufficient size in order to avoid any impermissible voltage drop when the fans start. For connection of the 400V type heaters, the correct phase sequence of the rotating field (clockwise) must be ensured. Incorrect connection can result in an incorrect direction of rotation of the fan. An emergency switch must be provided at an easily accessible point in the installation room for heaters with a nominal heat output from 50 kW. Attention All switches, if generally accessible, must be protected against damage and unauthorised use.

A sufficient and correct fuel supply must be ensured.
■ Only�������������������������� type-tested hot air heaters with forced-air oil burners complying with DIN EN 267 or forced-air gas burners (complying with DIN EN 676) may be used. ■ Power limitation for singlestage burner operation (up to 70 kW) is not required for hot air heaters.
■ The suction pipe must be provided with a foot valve in the fuel oil tank. ■ Free flowing fuel oil must be available in sufficient quantity also at low outside temperatures. Paraffin formation can occur already from about 5°C depending on the fuel oil quality. Appropriate measures must be taken to prevent this occurring!
Prior to initial use, the gas supply pipe must be cleaned thoroughly and checked for leaks!
Attention Installation, adjustment and maintenance of the gas supply must only be carried out by specialists authorised by GVU!
13
REMKO VRS Commissioning Commissioning of fan motor Testing drive 1. The mounting screws of the complete drive must be checked for tightness. 2. The initial tension of the drive belt(s) must be checked. Attention The fan must be checked for correct direction of rotation.
Current consumption measurement 1. To prevent incorrect measurements, the grilles in the air duct or air outlet hood must be opened. All supplied air inlet and metal panels must be mounted on the appliance. 2. Check the system voltage for correctness. 3. Carry out the necessary measurements and adjust settings as required.
■ Y / Δ - starting The measured rated current must not exceed the value shown on the motor rating plate. Note The rated current of the drive motor must be multiplied by the factor 0.58. Check the setting of the thermal overcurrent relay with respect to the calculated value and correct if necessary.
■ D irect starting The measured rated current must not exceed the value shown on the motor rating plate. Check the thermal overcurrent relay appropriate to the rated current of the drive motor and adjust if necessary.
14
Commissioning of the unit and the forced-air burner must take place by the manufacturer or a specialist authorised by the same. All regulating, control and safety devices must be checked for their proper functioning and correct adjustment. ■ The commissioning of oil and gas-fired heating appliances must always be carried out by authorised specialists.
Thermal overcurrent relay
■ All bolts and nuts of the fan and burner mounts must be checked for tightness.
The function of the overcurrent relay or its setting can be checked by removing a fuse. A correctly operating relay must operate after about 30 seconds.
■ A ll air outlet grilles must be opened and adjusted if necessary.
Attention The thermal overcurrent relay must only be operated in a manual mode. Under no circumstances must the relay switch on again automatically
Note In order to exclude measurement errors, each phase should be measured separately.
Commissioning
Excessive current consumption If the fan motor should consume excessive current despite correct electrical connection and sufficient system voltage, under no circumstances must the overcurrent relay be set higher or overridden. In this case, the air-sided resistances (inlet/outlet side) must be checked for correct dimensioning. Suitable measures must be provided for this purpose.
■ The settings and function of the triple function combination controller must be checked. ■ Switch on the local main switch or fuses. ■ Set the room thermostat higher than the existing room temperature. ■ Open the fuel supply and switch the switch to the „Heat“ position. Factory supplied oil burners start with a delay due to the standard oil preheating (up to VRS 50)! ■ The fuel oil or gas flow rate must be adjusted appropriate to the heat load of the appliance. See appliance rating plate!
■ The burner must be set to the values specified by the manufacturer, however at least to the values specified by the Federal Immission Control Act.
Heating
Ventilate
The appliances operate fully automatically depending on the room temperature.
1. Set the switch on the control box to the „II“ or „Ventilate“ position.
■ A measuring report must be prepared and handed to the operator for safe keeping.
1. Switch on the local main switch or fuse(s). 2. Open the fuel supply.
■ The operator must familiarise himself with the operation of the system.
3. Set the desired temperature on the room thermostat.
■ The responsible authorities must be provided with a declaration from the specialist company and certificate of the installer.
Information on corrosion in heat exchangers. ■ It
must be ensured that the exhaust fume temperature difference of 180 Kelvin is not reached. This prevents the risk of cooling below the dew point and related corrosion in the heat exchanger to a large extent.
Switching off 3. Set the switch on the control box to the „I“ or „Heat“ position.
230V type 400V type
Note If the heaters are not set to their nominal heat load (see rating plate) or are dimensioned too large for the necessary heat requirement, the burners operate in an intermittent mode. As the necessary operating temperature of the heat exchanger cannot be reached in intermittent operation, increased condensation unavoidably occurs with the consequence of higher corrosion in the heat exchanger.
In this switch position, the supply air fan runs continuously. The appliances can be used for air circulation or ventilation purposes. Thermostatic control is not possible.
It should be noted that the forcedair burner starts immediately on heat demand (except VRS 25 and 50), however the supply air fan initially starts automatically when the set temperature is reached. This prevents cold air from being blown out.
Set the switch on the control box to the „0“ position.
The supply air fan continues to operate to cool the heat exchanger and can start several times up to final switch off. Attention The heater must never be disconnected from the mains supply via the main or emergency switch before the cooling down phase has ended (except in emergency situations). For extended periods of non-use, the units should be disconnected from the power supply and the fuel supply shut-off.

REMKO VRS Cleaning and maintenance
Prior to carrying out maintenance or repairs, the unit must be disconnected from the mains supply.
■ The verification of work carried out by authorised specialists in addition to the usual reports must be provided in any event. Attention
Attention It does not suffice to switch off the unit only via the switch!
■ The complete heating appliance including heat exchanger, combustion chamber and forcedair burner must be cleaned to remove adhering dust and dirt. ■ The combustion residues in the combustion chamber and heat exchanger must be removed by suitable means. ■ The V-belt tension and motor mount must be checked at regular intervals. ■ Wearing parts such as flue gas brakes, seals, oil filter element and oil nozzles, etc. must be checked and replaced if necessary. ■ The maintenance instructions of the separate forced-air burner must be observed in any event.
16
Adjustment and maintenance of the forced-air burner must only be carried out by authorised specialists.
Note It is recommended to conclude a maintenance contract with an authorised specialist company for regular maintenance and cleaning.
Attention If the operational cleaning and burner adjustment intervals are not maintained, the warranty will be invalidated!
Soot deposits Small soot deposits on the heat transfer surfaces of the combus������� tion chamber and heat exchanger degrade heat emission. This reduces the overall efficiency of the system. A soot layer of 1 mm thickness causes an exhaust fume temperature increase of about 50 K (see diagram). 14

The operator is obliged to have the system inspected at least once a year for correct operation, reli����� ability, efficiency and maintenance of emission limits by an authorised specialist
This shows that an optimal burner setting and regular maintenance are essential for maintaining the efficiency and emission limits.
Cleaning the combustion chamber and heat exchanger 1. Disconnect the appliance from the mains supply. Attention It does not suffice to switch off the unit only via the switch!
2. Shut off the fuel supply. emove the following R components: 1. The forced-air burner. 2. Burner plate with burner flange. 3. Front lining plate(s). 4. One side lining plate (left or right depending on structural conditions).
10. The combustion residues in the combustion chamber must be removed though the burner opening also using a suitable vacuum cleaner. A special boiler cleaning set for the REMKO industrial vacuum cleaner is available as an accessory. 11. After cleaning, all parts must be carefully refitted in reverse order.
12. The correct assignment of the exchanger tubes and correct seating of all seals must be ensured. Damaged or deformed seals must be replaced. 13. Burner maintenance must be carried out as specified in the separate operating instructions of the burner.
Note The limitation of exhaust fume losses must be maintained in accordance with §11 of the Ordinance on Small Firing Installations (1st BImSchV).
ATTENTION The burner and all control units must be checked for perfect functioning.
5. The two front inspection covers. 6. The side inspection cover. 7. Remove the flue gas brakes from the heat exchanger tubes and clean or replace if damaged. The correct assignment of the exchanger tubes must be ensured! 8. Clean the heat exchanger tubes with suitable cleaning agents to remove adhering combustion residues.

REMKO VRS Troubleshooting The heater does not start ■ Check the local mains supply connection. ■ Check the fuses in the control box. (Only 400V three-phase type) ■ Set the switch to the „I“ or Heat position. ■ Check that the „Burner“ indicator light on the control box (only 400V type) is illuminated. ■ Check the thermostat connection or room thermostat cable. ■ Check the room thermostat setting. The temperature set must be higher than the existing room temperature. ■ Check whether the safety temperature limiter (STB) may have operated.
Possible causes:
The burner does not start
■ The heaters could not cool down because the power supply was interrupted. A brief interruption of the power supply can also cause the STB to operate.
■ Check the oil filter for clogging. Replace clogged filter(s).
■ The temperature of the air being blown out is too high due to incorrectly installed chimney ducts or adjusted grilles. ■ The fan was overloaded and the thermal overcurrent relay of the 400V type heater or thermal contacts in the fan motor of the 230V type heater have operated. ■ The V-belt for the fan drive is loose or faulty. ■ The air inlet or outlet is not free.
■ Check that the shut-off valve on the oil filter is open. ■ Check the fuel tank f��������� or sufficient fuel. ■ Check the fuel and filter for paraffin separation. Paraffin separation can occur already below 5°C. ■ Check the oil hoses for damage and leaks. Air may also be sucked in! ■ Check the safety temperature limiter (STB). ■ Check the temperature monitor (TW).
■ Check the temperature control thermostat (TR) for correct functioning and adjustment. ■ Check the temperature monitor (TW) for correct functioning and adjustment.
Attention Prior to carrying out maintenance or repairs, the unit must be disconnected from the mains supply.
18
Attention Prior to releasing a safety device, the cause of operation must be located and eliminated.
Note Safety devices must not be overridden or blocked during heater operation!
The supply air fan does not start ■ Check the capillary tubes and sensors of the triple function combination controller for damage and correct positioning of the sensors.
Set the switch to the „II“ or „Ventilate“ position. The supply air fan should now start!
■ Check whether the fault indicator light of the burner relay is illuminated. ■ If the fault indicator light is illuminated, release the burner relay by pressing the fault button. The fault indicator light extinguishes and the burner attempts to start! ■ With VRS 25 and 50 heating appliances, the burner starts with a delay due to the oil preheating (only factory supplied burners)
NOTE If no result is achieved after carrying out all functional checks, an authorised service station should be contacted.
Attention 230V type
400V type
Repairs to the electrical installation and burner must only be carried out by authorised specialists for safety reasons.
If the fan does not start: ■ C heck the local mains supply connection. ■ Check the fan and drive for smooth operation. ■ Check the V-belt of the fan drive.
Attention Adjustment and maintenance of the appliance and forced-air burner must only be carried out by authorised specialists!
■ Check the electrical cables at the fan motor for damage. Attention If the burner should shutdown after starting due to a fault, a release attempt can only take place after five minutes.
No further release attempts should be made in any event due to a risk of deflagration.
■ Check the fan to ascertain whether it was overloaded and if the thermal overcurrent relay of the 400V type heater or thermal contacts in the fan motor of the 230V type heater have operated. ■ Check the capacitor in the fan of the 230V type heater.
