INSTALLATION : COMBUSTION AIR INLET
COMBUSTION AIR INLET The outdoor portion of the inlet duct consists of a 7” diameter fresh air intake hood with a galvanized mesh screen. The hood is provided with your GARN® WHS; the other items (screws, tape, caulk) must be provided on site.

Combustion air for the GARN® is ducted from outside through a dedicated 7” diameter single wall duct. The GARN® must be connected to an outside air source. The air duct may have no more than two (2) 90-degree bends and its total length cannot exceed 12 ’ when using 7” diameter duct. The combustion air inlet duct does not require a wall thimble. The air inlet should extend above any obstructions and possible snow drifts.
