Installing A Tandem ® Transition* Kit - Broan SKY Series Installation And User Manual

3 Installation
3.3 Installing the Registers, Ductwork and Hoods
3.3.3 Hoods
Refer to applicable building codes to plan where the stale air exhaust hood and fresh air distribution hood should be
installed. Below are some general recommendations.
• Exhaust hood must have a backdraft damper.
Make sure intake hood is located at least 10 feet away from any of the following (6 feet in Canada):
• 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 (6 feet in Canada) 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.
3.4 Installing a Tandem
If using a Tandem Transition, a backdraft damper must be installed on the stale air to outdoors duct. If this causes an
interruption in the duct insulation, insulation must be added around the backdraft damper to avoid condensation.
If desired, a Tandem transition kit can be used instead of 2 exterior hoods.
Follow the instructions included with the tandem termination kit.
