CAUTION: Use of bulbs greater than 20 watts will cause the fuse to open.
HEAT SENTRY™
Your hood 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, do it from the main electrical panel.

INSTALL THE DUCTWORK
(DUCTEDHOODSONLY)
!
WARNING: To reduce the risk of fire,
use only metal ductwork.
1. Decide where the ductwork will run
between the hood and the outside.
2. Astraight,shortduct runwillallowthehood
to perform most efficiently.
3. Long duct runs, elbows, and transitions
will reduce the performance of the hood.
Use as few of them as possible. Larger
ducting may be required for best
performance with longer duct runs.
4. Install a roof or wall cap. Connect round
metal ductwork to cap and work back to-
wardshoodlocation.Use duct tapetoseal
the joints between ductwork sections.
