DEFRA Stove Installation and User Guide
Note: If the appliance is fitted with a draught stabiliser (or if one is fitted
to the flue pipe or chimney in the same room as the appliance) then the
permanent air entry opening (or openings) should be increased by 300mm
2
for each kW of rated output up to 5kW and an additional 850mm
2
for each
kW output over 5kW.
If there is more than one appliance in the property then each appliance
must be supplied with adequate combustion air so that all appliances can
be lit simultaneously.
The positioning of any air vent must be so that it cannot be liable to
blockage or obstruction. Ideally it should also be positioned where it is
unlikely to cause a cold draught. It should not be positioned in the fireplace
recess.
The fitting of an extractor fan in the same room as the
stove, or an adjacent room is not permitted. A spillage test
will be required to determine how any extractor fans may
affect the required size of ventilation requirements.
For more detailed guidelines on required ventilation sizes please refer
to the HETAS Guide which can be found on the HETAS website.
If you plan to use an external air supply on a suitable stove, and have
bought the appropriate Arada External Air Supply Kit, please refer to the
instructions included with the kit on how to install it.
The accompanying stove technical product sheet states whether or not
your appliance is compatible with a Direct Air Supply Kit.
