6.8 INSTALLING TWO EXTERIOR HOODS* (GSVH1K, GSHH3K AND GSEH3K MODELS ONLY) (CONT’D)
6.8.2 L
OCATING THE AIRDUO™ AND OPTIONAL EXTERIOR SINGLE HOOD
The AirDuo™ exterior hood must be installed at a minimum distance of 4 inches (102 mm) from the ground, and the optional single fresh
air intake exterior hood must be installed at a minimum distance of 18 inches (457 mm) from the ground. Also, a minimum distance of
3 feet (0.9 m) is required between the hoods to avoid cross-contamination. See illustration below.
6.8.3 CONNECTING INSULATED DUCTS TO EXTERIOR HOODS
1. For each exterior hood, using a jigsaw, cut a 6’’ diameter hole (if using 5’’ dia. insulated duct) or a 7’’ diameter hole (if using 6’’ dia.
insulated duct) in the exterior wall. Identify each insulated duct. For fresh air from outside duct, use the blue sticker dots (one at
each end). For exhaust to outside duct, use the red sticker dots (one dot at each end). Run each flexible duct through its respective hole
in the wall.
2. Pull back the insulation to expose the flexible duct and, using a tie wrap, attach it to the inner
ring of the exterior backplate (5’’ ring for the 5’’ insulated ducts or 6’’ ring for the 6’’ insulated
ducts). Carefully seal with duct tape (A). Pull the insulation over the joint. Pull the vapor barrier
over the insulation and over the outer ring of the exterior backplate. Apply gently duct tape to
the joint making an airtight seal (B).
6. INSTALL THE UNIT (CONT’D)
WARNING
Make sure the AirDuo™ hood is at least 3 feet (0.9 m) away from any of the following:
• High efficiency furnace vent. • Any exhaust from a combustion source.
• Gas meter exhaust, gas barbecue-grill. • Garbage bin and any other source of contamination.
