1. Mount the air intake hood through an outside wall. It must be at least 12”
(inches) ABOVE grade or snow line.
2. Locate the air intake hood at least 3’ (feet) BELOW (or 6 feet horizontally
from) any appliance VENT termination.
3. When the appliance is sidewall vented, locate the air intake hood on the
same side of the building as the appliance vent outlet.
4. Always mount the air hood with the intake pointed down.
5. To install the air intake hood, cut a 4 ¼” hole through the side of the
building. Slide the hood through the wall and fasten with appropriate
screws.
6. Seal around the exterior plate with an exterior rated caulk, silicone sealant
or equivalent.
7. Locate the air hood so the air piping length doesn’t exceed the limits
below:
Number of Elbows
Maximum Length
of Air Pipe
2 to 4
35 Feet
5
28 Feet
6
21 Feet
7
14 Feet
8. Construct the air duct piping with 4” diameter dryer vent or aluminum or
