6.7INSTALLING THE EXTERIOR HOODS

CAUTION

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 location for 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 fall.

6.8CONNECTING THE DRAIN

VO0003 1

Attach the 2 plastic drain fittings to the unit using the gaskets, washers and nuts as shown.

	12"(305 mm)
VO0004	2

Cut 2 sections of plastic tubing, about 12” (305 mm) long and attach them to each drain fitting.

VO0005

Join the 2 short sections to the “T” junction and main tube 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.
