dwelling. Where any duct runs outside the
insulated envelope they must be insulated.
Design the duct runs so as to avoid noise transmission and
“crosstalk” particularly with separate branches to the dampers.
Ducts should always have an adequate diameter for the air

the duct system is higher, the performance of the appliance will
be adversely affected.
The exterior air supply should be on the sheltered or leeward
side of the building and can be sited on the roof or wall. The
exhaust air terminal should be sited on the roof well away from
