Make sure intake hood is located at least 10 feet away from any of the following:
• Dryer exhaust, central vacuum vent
• Gas meter exhaust, gas barbecue-grill
• Any exhaust vents or chimney from a combustion source
• Garbage bin and any other source of contamination such as parking lots, streets
For multifamily buildings only:
Make sure exhaust hood is located at least 3 feet away from any of the following:
• Property lines
• Operable openings into buildings (door, window)
• Intake and exhaust hood(s) shall be protected with corrosion-resistant screens, louvers or grilles having openings not less than
1/4 inch and not larger than 1/2 inch.
• Install hood(s) at least at 18 inches away from the ground OR depth of expected snow accumulation, whichever is greater.
To minimize cross-contamination of exhausted stale air into the fresh air intake:
Single detached, attached homes and townhouses:
• Maintain a 6 feet minimum separation distance between outdoor air intake and exhaust hoods OR use an approved factory-built
intake/exhaust combination termination fitting.
Multifamily buildings:
• Maintain a 10 feet minimum separation distance between outdoor air intake and exhaust hoods OR use an approved factory-built
intake/exhaust combination termination fitting.
Ignoring these recommendations could significantly degrade the quality of the incoming air which, in some cases, could result in health
consequences. In the event of a conflict between our recommendations and any local requirements, the latter shall have priority.
Refer to illustration below for an example of proper connection method of the insulated ducts to the hoods. An "Anti-Gust Intake Hood"
should be installed in regions where snow is expected.
