• Pliers
INSTALL THE DUCTWORK
NOTE: To reduce the risk of fire, use only metal ductwork.
1. Decide where the ductwork will run between the insert and
the outside (FIG. 1).
2. Choose desired blower outlet position (FIG. 2).
3. A straight, short duct run using 8" round damper (included
with blower kit) for single internal blower and 10" round
damper (included with the hood) for all other blower types
will allow the hood to perform most efficiently.
4. Long duct runs, elbows and transitions will reduce the
performance of the hood. Use as few of them as possible.
5. Install wall cap or roof cap (sold separately). Connect metal
ductwork to cap and work back towards the hood location. Use
2" foil duct tape to seal the joints between ductwork
sections.
BLOWER OUTLET POSITION
There are four (4) possible outlet positions:
• Top
• Front
• Back
• Side
The damper can be installed on the housing prior to install
the hood in the ceiling with Side and Top outlet positions only.
In the case of Front and Back outlet positions, the damper
has to be installed on the housing once the hood is installed
in the ceiling.
10" damper included with the hood needs to be used for all exterior blower setup and internal blower PM12. With external
blower, ducting is to be connected directly on the damper (no rough-in plate required).
5
6" damper is needed only with PM6 internal blower. It is included in the PM6 blower kit.
• Metal foil duct tape
• Scissors (to cut metal foil duct tape)
• Pencil
• Wire stripper
• Strain relief(s), 7/8" diameter (one to secure house
wiring cable to the hood and another one to secure
external blower cable to the hood)
