Always ensure that adequate combustion air is provided
to suit the total installation of all combustion equipment
in accordance with BS6230 or BS5440 as appropriate.
Ensure that the air combustion inlet opening at the rear side
of the unit cannot be obstructed (cfr. fig. 3).
Combustion air inlet pipe & flue pipe for balanced flue
installation (type C appliances)
Balanced flue air heaters are designed to be fitted with a
combustion air inlet duct that obtains outdoor air and a flue
pipe that exhausts flue products to outdoors. Both the flue
and combustion air pipes must be sealed. Use gasket sealed
seamless aluminium or stainless steel pipe or equivalent.
For testing, the flue pipe should include a sealable test port.
Type C2 appliances must not be applied !

AIR SUPPLY
When these air heaters are installed in type B applica-
tions, designed to take air for combustion from the space
in which it is installed. Do not restrict the combustion
air intake.
It is important to ensure that there is an adequate air supply
at all times for both combustion and heating requirements.
Modern buildings involve greater use of insulation, improved
vapour barriers, and weather proofing. These practices mean
that buildings are sealed much tighter than in the past.
Proper combustion air supply for a power vented Type B
installation requires ventilation of the heated space. Natural
infiltration of air may not be adequate. Use of exhaust fans
aggravates this situation. It is important to ensure that there
is adequate combustion air supply at all times. Reliance on
doors and windows is not allowed.
