All models require an exhaust hood with a backdraft damper. This damper closes when the unit is
off and prevents unwanted cold air from entering the house.
Choose
an
appropriate
installing the exterior hoods:
•
a minimum distance of 6 feet (1.8 m)
between the hoods to avoid
cross-contamination
•
a minimum distance of 18 inches (457 mm)
from the ground
Make sure the intake hood is at least 6 feet
(1.8 m) away from any of the following:
•
dryer exhaust, high efficiency furnace
vent, central vacuum vent
•
gas meter exhaust, gas barbecue-grill
•
any exhaust from a combustion source
•
garbage bin and any other source of
contamination
Refer to figure 15 for connecting the insulat-
ed duct to the hoods. Place the "FRESH
AIR INTAKE" sticker, provided in the instal-
lation kit, on corresponding hood. An "Anti-
Gust Intake Hood" should be installed in
regions where a lot of snow is expected to

ONNECTING THE
VO0003
Attach the 2 plastic drain fittings
to the unit using the gaskets,
washers and nuts as shown.
Make a water trap loop in the tube to prevent the unit from drawing
unpleasant odors from the drain source. Make sure this loop is
situated BELOW the "T" as shown. This will prevent water from
being drawn back up into the unit in case of negative pressure. Run
the tube to the floor drain or to an alternative drain pipe or pail. Be
sure there is a slight slope for the run-off.
