1.8.3 Ducted Air Inlet Considerations.
Heat resistant flexible tube is connected to the
burner assembly ducted air adaptor and the
EVM ducted air adaptor and connected to the
air supply duct
The maximum length of 100mm diameter
ductwork is 2m.
Ensure that the flexible supply duct does not
drape over or touch the reflector.
Ensure that the flexible ductwork is installed to
allow for expansion of the heating system.
On a header duct, the main air supply header
which is feeding the individual branch ducts and
burner/end vent supply ducts must have a
maximum pressure drop of 0.25 mbar (0.1in
wg).
All joints and seams in the air supply system
must be made air tight and a bird screen used at
the inlet.
For full details refer to section 2.13
