Locating Intake Weatherhood

The intake weatherhood should be located as follows:

•4 - 6' from ventilation exhaust hood, and upstream of prevailing winds, if possible.

•At least 6' from a dryer vent, oil fill pipes, combustion outlets, gas meters, garbage containers or anything else, which may contaminate the air.

•Do not locate fresh air intake in garages, crawl spaces or attics.

•Install 18" above grade, or above expected snow accumulation.

Locating the Exhaust Weatherhoods

The Exhaust Weatherhood should be located as follows:

• At least 4-6' from the supply inlet

•

At least 18" above grade or expected

 

snow accumulation

•

At least 3' from gas meters, combustion

 

vents, or dryer vents

Outside Ducting the Weatherhoods

The ventilation portion of the Clean Air Furnace can be vented off either side of the unit by removing knockouts provided. Once the knock outs in are removed, a bead of silicone can be placed on the plastic thermo-collars (provided), to form a seal between the collars and the cabinet. The collars can then be fastened into place with screws. Note the exhaust outlet is always the port on the bottom, and the supply inlet is always the port on the top, both ports should be labeled from the factory as such.

The ductwork from the outside weatherhoods to the unit, is usually flexible ducting, although rigid pipe may be needed if the runs are greater than 20 feet. In either case the pipes (both exhaust and supply and the added fittings) must be insulated, with a complete vapor barrier. To minimize restriction in airflows the ducting should be short, with as few bends as possible. See diagram below for recommended connection of insulated ducting to outside weatherhoods.
