5.1.4 Exempt appliances

Exempt appliances are appliances (ovens, wood burners and stoves) which have been exempted under the Clean
Air Act 1993 or Clean Air (Northern Ireland) Order 1981.

5.1.5 Outside air connection

Some fires can be provided with an outside air connection. For an optimum operation of the appliance, the
following should be taken into account in case of an outside air connection:
• The passage of the outside air connection and possibly the passage of a grate may not be smaller than the
passage of the outside air connection on the fire.
• Make sure the maximum underpressure created in the combustion air supply pipe is 4 pascal. If a higher
underpressure is created, the fire will not function properly and (hot) flue gases may flow back into the supply
pipe.
• Prevent placing the outside air supply in an underpressure area on the outside of the house. If possible, place a
supply pipe with T piece to 2 sides of the house.
• The combustion air supply pipe may not be placed higher than the bottom of the fire. This will prevent flue gases
from flowing back.
• The combustion air pipe that is connected to the fire should be made of non combustible material.
• The fire will function properly with a flexible pipe with a maximum length of 11 metres and 4 bends. In case of a
longer pipe or more bends, we recommend placing a pipe with a larger diameter (100-125mm).
• If a crawl space is properly aerated with open grates, it is allowed to retrieve combustion air from there. If there is
no proper aeration in the crawl space, it is possible that harmful radon gases are drawn in. This is not allowed
according to national regulations.
Further information on the outside air connection, if applicable, can be found in section 9 'Appliance specific
information'.
Please note that HETAS product approval remains valid for the appliance only when installed with its air supply
taken from the room of installation and the room is ventilated permanently to outside air as necessary in
accordance with the guidelines given in Approved Document J. HETAS product approval is not valid for
appliances fitted with an external air supply ducted directly to the appliance.
