For the most efficient and quiet operation:
Cold Weather Installations:
An additional backdraft damper should be installed to minimize backward
cold air flow and a thermal break should be installed to minimize conduction
of outside temperatures as part of the duct system. The damper should be on
the cold air side of the thermal break.
The break should be as close as possible to where the duct system enters the
heated portion of the house.
Makeup Air:
Local building codes may require the use of makeup air systems when using
ventilation systems greater than specified CFM of air movement. The specified
CFM varies from locale to locale. Consult your HVAC professional for specific
requirements in your area.
• Use rigid metal duct.
• Use no more than three 90° elbows.
• Make sure there is a minimum of 25 ⁹/₁₆" (65.0 cm) of straight duct
between the elbows if more than 1 elbow is used.
• Do not install 2 elbows together.
• Use clamps to seal all joints in the duct system.
• The duct system must have a damper. If the roof or wall cap has
a
damper, do not use the damper supplied with the range hood.
• Use caulking to seal exterior wall or roof opening around the cap.
• The size of the duct should be uniform.
