1.3 ANTI-FREEZE PROTECTION. Minimum temperature -5°C standard with an anti-freeze function that activates the pump and burner when the system water anti-freeze function is only guaranteed if: - the boiler is correctly connected to gas and electricity power supply circuits; - the boiler is powered constantly; - the boiler is not in no ignition block (Par. 2.5); - the boiler essential components are not faulty. In these conditions the boiler is protected against freezing to an environmental temperature of -5°C. Minimum temperature -15°C. If the boiler is installed in a place where the temperature falls below -5°C and in the event there is no gas, or the boiler goes into ignition block, the appliance may freeze. To prevent the risk of freezing follow the instructions below: - Protect the central heating circuit from freezing by introducing a good quality anti-freeze liquid carefully following the manufaturer's instructions regarding the percentage necessary with respect to the minimum temperature required for preserving the system.
The Boiler is made from materials that are resistant to ethylene and propylene glycol-based anti-freeze liquids. For life and possible disposal, follow the supplier's instructions. - Protect the condensate drain trap and circuit board against freezing by using an accessory that is supplied on request (anti-freeze kit) comprising two electric heating elements, the relevant cables and a control thermostat (carefully read the installation instructions contained in the accessory kit pack). Boiler anti-freeze protection is thus ensured only if: - the boiler is correctly connected to gas and electricity power supply circuits and powered; In these conditions the boiler is protected against freezing to temperature of -15°C. interruption of the electrical power supply and failure to comply with that stated on the previous page. N.B.: if the boiler is installed in places where the temperature falls below 0°C the domestic water and heating attachment pipes must be insulated.

Attention: in order not to void the warranty before making the boiler connections, carefully clean the heating system on the primary heat exchanger (pipes, radiators, etc.) with special cleaning products (Fernox) to remove any deposits that could compromise correct boiler operation. Chemical Treatment of the heating system water is required, in compliance with the technical standards in force, in order to protect the system and the appliance from deposits (e.g., lime scale), slurry or other hazardous deposits. Products like Fernox are suitable for are maditory when using chemicals / water treatments or alternatively, ensure physical air break.

INSTRUCTIONS FOR USE AND MAINTENANCE.
2.1 CLEANING AND MAINTENANCE. Attention: the heating systems must undergo periodical maintenance (regarding this, see in the section dedicated to the maintenance / Hunt Heating authorised service engineer, relative to “yearly appliance check and maintenance”) and regular combustion and energy efficiency checks in compliance with AS 5601. This ensures that the optimal safety, performance and operation of the boiler remain unchanged over time. We recommend your appliance is service annually.
MAINTENANCE TECHNICIAN
USER
2.2 GENERAL WARNINGS. Use of the boiler by unskilled persons or children is strictly prohibited.
If temporary shutdown of the boiler is required, proceed as follows: a) drain the heating system if anti-freeze is not used; b) shut-off all electrical, water and gas supplies. In the case of work or maintenance to structures located in the vicinity of ducting or devices for flue extraction and relative accessories, switch off the appliance and on completion of operations ensure that a qualified Hunt Heating technician checks efficiency of the ducting or other devices. Never clean the appliance or connected parts with easily flammable substances. Never leave containers or flammable substances in the same environment as the appliance.
- the appliance power cable must not be replaced by the user; - in the event of damage to the cable, switch off the appliance and contact a qualified technician; - if the appliance is not to be used for a certain period, disconnect the main power switch.
t Attention: the use of components involving use of electrical power requires some fundamental rules to be observed: - do not touch the appliance with wet or moist parts of the body; do not touch when barefoot.

All information relative to the anti-freeze protection is stated in Par. 1.3. In order to guarantee the integrity of the appliance and the heating system in zones where the temperature falls below zero, we recommend the central heating system is protected using anti-freeze liquid. In the case of prolonged inactivity (second case), we also recommend that: - the electric power supply is disconnected; - the heating circuit and boiler domestic water circuit must be drained. In systems that are with suitably treated water to eliminate hardness that can cause lime-scale. Inhibitors can be purchased from Hunt Heating. 2.10 DECOMMISSIONING.
