Cold Weather Installations; Makeup Air; Venting Methods - Whirlpool LIB0131212B Instructions D'installation Et Guide D'utilisation Et D'entretien

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
vent 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 vent
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 with 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.

Calculate Vent System Length
The recommended vent system is 6" (15.2 cm) round vent with a
maximum length of 35 ft (10.7 m). For the best performance, use
no more than three 90° elbows.
To calculate the length of the system, add the equivalent feet
(meters) for each of the vent pieces used in the system.

Non-Vented (recirculating) Installations Through the
Soffit/Cabinet
If it is not possible to vent cooking fumes and vapors to
the outside, the range hood can be used in the non-vented
(recirculating) version, using a charcoal filter. Charcoal Filter Kit
is available from the dealer or an authorized parts distributor.
See the "Assistance or Service" section to order.
