Make-Up Air Damper Relay
Switch (optional)
Local codes may require the use of an additional backdraft
and/or make-up air damper. Contact your local HVAC
professional for specific requirements.
This hood provides a relay switch to connect a Make-Up
Air Damper (120V max). Installations will vary according to
the location in the home where the unit is installed and the
damper used. Use the following illustration as guidance
for your installation. Always comply with local code
requirements.
1. Access the hood's wiring.
2. Route the Make-up Air Damper harness through the
strain relief to the terminal block.
• The Make-up air kit hot and return connections
can use either terminal connection. There is no
polarity requirement for the two pin terminal
block.
3. Secure the ground wire with the green T-20 ground
screw.
Duct Cover Installation
(optional)
On some models, an optional duct cover may be used to
fill the space between the hood and ceiling in wall mount
installations. Accessory 6'' or 20'' – 54'' telescoping duct
covers are available for purchase separately.
The duct cover structure is supported by the hood.
1. Attach the duct cover(s) to the hood using sheet metal
screws as shown above. Screw quantity is dependent
on hood size.
2. From inside of hood, insert 5/8'' (16 mm) screws
supplied through the holes indicated on each side and
along the front, into bottom of the cover.
