INSTALL THE DUCTWORK
(DUCTED INSTALLATION ONLY)
NOTE: To reduce the risk of fire, use only metal ductwork.
1. Decide where the ductwork will run between the powerpack
insert and the outside. (FIG. 1)
2. A straight, short duct run will allow the powerpack insert
to perform most efficiently.
3. Long duct runs, elbows, and transitions will reduce the
performance of the powerpack insert. Use as few of
them as possible. Larger ducting may be required for best
performance with longer duct runs.
4. Install wall cap or roof cap (sold separately). Connect metal
ductwork to cap and work back towards the powerpack
insert location. Use 2” metal foil duct tape to seal the joints
between ductwork sections.

ALL UNITS
HEAT SENTRY™
Your unit is equipped with a HEAT SENTRY™ thermostat.
This thermostat is a device that will turn on or speed up the blower
if it senses excessive heat above the cooking surface.
1) If blower is OFF - it turns blower ON to HIGH speed.
2) If blower is ON at a lower speed setting - it turns blower
up to HIGH speed.
When the temperature level drops to normal, the blower will return
to its original setting.
WARNING
The HEAT SENTRY thermostat can start the blower
even if the hood is turned OFF. When this occurs, it
is impossible to turn the blower OFF with its switch.
If you must stop the blower, set the main power
switch (located behind the filters, on inner side of
the unit faceplate) in OFF position (if it is possible to
do so safely). See inset in FIG. 31.
