This may be reduced to no less than 100mm when permitted by the appliance manufacturer and supported by calculation according to BS EN 13384-1:2002. This calculation can be applied to an individual installation or manufacturers can provide pre-calculated designs.
NOTES: 1. 2. 3.
Closed appliances include cookers, stoves, room heaters and boilers Fuels such as bituminous coal, untreated wood or compressed paper are not smokeless or low-volatiles fuels. These appliances are known as „exempted fireplaces‟.
An overly large chimney aperture will mean that too much energy will be required to heat the chimney sufficiently to achieve an acceptable draught. If you have a brick chimney with a large aperture, we recommend that you install an insulating chimney liner of the proper diameter. This will increase the draught, and improve the fuel economy. The height and positioning of the chimney must comply with the guidance given in Approved Document J of The Building Regulations, particularly Sections 2.6 – 2.21. The chimney must be accessible for external inspection, and it must be possible to access the cleaning doors and the chimney if it is to be cleaned from the top (e.g. steel chimneys). Be aware of the following: If there is insufficient draught in the chimney, it may be a good idea to install the flue pipe straight up so as to minimise smoke migration in the actual combustion chamber. Avoid having more bends than necessary, and limit the length of the flue pipe so as not to reduce the draught.
3.2 Fresh air supply A wood-burning stove requires air for combustion. As a result, firing a wood-burning stove will help create a healthy climate in your house. The ventilation requirements are described in Sections 2.1 – 2.3 and Table 1 of the Approved Document J. If it is necessary to install air grilles, they must be positioned so that they cannot be obstructed.

5 3.3 Draught conditions If smoke comes out of the stove when the fire door is opened, it will be due to the poor draught in the chimney. This type of stove requires at least 12 Pa of chimney draught to achieve satisfactory combustion and to prevent smoke from escaping. Smoke may, however, escape in any event if the stove door is opened during vigorous firing, so this should be avoided. If in doubt, you may want to get your chimney sweep to measure the draught in the chimney. 3.3.1 Draught The draught in the chimney is the result of the difference between the high temperature in the chimney and the cooler temperature outside. Other factors that determine whether sufficient negative pressure can be produced to create a draught include the length and insulation of the chimney, and wind and weather conditions. In the unusual event of adverse weather conditions that cause downdraught, the appliance must not be used. 3.3.2 The draught will be reduced when: - The temperature difference is too low, e.g. in connection with a poorly insulated chimney. If the chimney is cold, it may help to light (burn up) a rolled-up newspaper in the chimney‟s cleaning door. - The outside temperature is too high, e.g. during the summer. - There is no wind. - The chimney is not tall enough, with the result that it sits in the lee of the roof surface or tall trees. These conditions are also associated with the greatest risk of smoke coming back down the chimney. - Air is entering the chimney in undesired places, e.g. through cracked joints or leaks in the cleaning door or the flue pipe. - Unsealed, unused fireplaces are connected to the chimney. - The flue pipe and chimney are clogged up with soot due to inadequate cleaning. - The house is too tightly sealed (please see the section on Fresh air supply). 3.3.3 A good draught is achieved when: - There is a big difference between the temperature in the chimney and outside, i.e. when the need for heating is greatest. - The weather is clear and there is a good wind. - The chimney is of the proper height, i.e. Minimum 4 metres above the stove, and clear of the spine of the roof.
4. Chimney sweep You may need to consult your local chimney sweep before installing the stove. After the stove has been installed, advise the owner/user to have the chimney system checked and swept at least once a year. If the chimney system has not been used for some time, it should be inspected for cracking, bird nests, etc. before it is put back into use.
5. Stove placement/clearance and floor protector requirements Clearance requirements apply only if the stove is placed near to combustible materials. Permitted clearances to combustible materials are also indicated on the data plate on the rear of the stove.

A = 150mm B = 345mm C = 220mm NB Clearances are measured from the edge of the top castings.
5.1 Floor protector requirements This appliance has been tested as required under ADJ Page 37 Item 2.23a and maximum temperature rise recorded at 37°C. Only a hearth made of non-combustible board/sheet materials or tiles at least 12mm thick are required. The heater should always be installed on top of its leg base due to high temperaturessustained over long periods of use. It is recommended that the appliance be secured to the floor protector to ensure stability with the brackets supplied. In situations where the stove is to be fitted into a brick or non-combustible recess, we recommend that the stove is installed with at least 100mm clearance to the wall, this will allow room air to circulate around the stove; also the maintenance of the outside stove is easier. When applied to masonry, a layer of wallpaper is normally classified as a non-combustible surface.
5.2 On the floor National and Local Building Regulations must again be observed when considering the type, thickness and area of the hearth to be used in the installation. Max Hearth temperature under safety test was 37°C. One should of course always make certain that the underlying floor surface can bear the weight of the stove.
5.3 Clearance to furniture and soft furnishings We recommend that the stove be installed 700 mm from furniture. Serious consideration should also be given to positioning of any furniture that could be adversely affected by heat. The clearances to combustible materials in front of the stove should be a minimum of 700 mm. When lit, a wood-burning stove gets hot and therefore adequate protect must be provided, particularly in situations where there is a safety risk to children or the infirm. A suitable safety guard around the stove should be considered.
6. HETAS amendments 6.1 More detailed advice about existing chimney usage NOTE: A chimney height of not less than 4.5 metres measured vertically from the outlet of the stove to the top of the chimney should be satisfactory. Alternatively the calculation procedure given in EN 13384-1 may be used as the basis for deciding whether a particular chimney design will provide sufficient draught. The outlet from the chimney should be above the roof of the building in accordance with the provisions of Building Regulations Approved Document J. If installation is into an existing chimney then it must be sound and have no cracks or other faults which might allow fumes into the house. Older properties, especially, may have chimney faults or the cross section may be too large i.e. more than 230 mm x 230 mm. Remedial action should be taken, if required, seeking expert advice, if necessary. If it is found necessary to line the chimney then a flue liner suitable for solid fuel must be used in accordance with Building Regulations Approved Document J. Any existing chimney must be clear of obstruction and have been swept clean immediately before installation of the stove. If the stove is fitted in place of an open fire then the chimney should be swept one month after installation to clear any soot falls which may have occurred due to the difference in combustion between the stove and the open fire.
CI-2013-05-14
7 If there is no existing chimney then any new system must be to the designation described above and in accordance with Building Regulations Approved Document J. A single wall metal fluepipe is suitable for connecting the stove to the chimney but is not suitable for use as the complete chimney. The chimney and connecting fluepipe must have a minimum diameter of 150 mm and its dimension should be not less than the size of the outlet socket of the stove. Any bend in the chimney or connecting fluepipe should not exceed 45°. 90° bends should not be used. Combustible material should not be located where the heat dissipating through the walls of fireplaces or flues could ignite it. Therefore when installing the stove in the presence of combustible materials due account must be taken of the guidance on the separation of combustible material given in Building Regulations Approved Document J and also in these stove instructions. If it is found that there is excessive draught in the chimney then a draught stabiliser should be fitted. Fitting of a draught stabiliser will affect the requirement for the permanent air supply into the room in which the stove is fitted in accordance with Approved Document J (see also combustion air supply).
6.2 Commissioning and handover Ensure all parts are fitted in accordance with the instructions. On completion of the installation allow a suitable period of time for any fire cement and mortar to dry out, before lighting the stove. Once the stove is under fire check all seals for soundness and check that the flue is functioning correctly and that all products of combustion are vented safely to atmosphere via the chimney terminal. On completion of the installation and commissioning ensure that the operating instructions for the stove are left with the customer. Ensure to advise the customer on the correct use of the appliance and warn them to use only the recommended fuel for the stove. Advise the user what to do should smoke or fumes be emitted from the stove. The customer should be warned to use a fireguard to BS 8423:2002 (Replaces BS 6539) in the presence of children, aged and/or infirm persons.
6.3 Extractor fan There must not be an extractor fan fitted in the same room as the stove as this can cause the stove to emit smoke and fumes into the room. 6.4 Permanent air vent The stove requires a permanent and adequate air supply in order for it to operate safely and efficiently. In accordance with current Building Regulations the installer may have fitted a permanent air supply vent into the room in which the stove is installed to provide combustion air. This air vent should not under any circumstances be shut off or sealed.
6.5 Chimney cleaning The chimney should be swept at least twice a year. It is important that the flue connection and chimney are swept prior to lighting up after a prolonged shutdown period. If the stove is fitted in place of an open fire then the chimney will require sweeping after a month of continuous operation. This is a precaution to ensure that any “softer” deposits left from the open fire usage have not been loosened by the higher flue temperatures generated by the closed stove.
6.6 Use of fireguard When using the stove in situations where children, aged and/or infirm persons are present a fireguard must be used to prevent accidental contact with the stove. The fireguard should be manufactured in accordance with BS 8423:2002 (Replaces BS 6539).
6.7 Use of operating tools Always use the operating tools provided when handling parts likely to be hot when the stove is in use.
6.8CO Alarms Building regulations require that whenever a new or replacement fixed solid fuel or wood/biomass appliance is installed in a dwelling a carbon monoxide alarm must be fitted in the same room as the appliance. Further guidance on the installation of the carbon monoxide alarm is available in BS EN 50292:2002 and from the alarm manufacturer‟s instructions. Provision of an alarm must not be considered a substitute for either installing the appliance correctly or ensuring regular servicing and maintenance of the appliance and chimney system.
