3.2 HIGH LIMIT SWITCH
This thermally activated switch, located in front of
the draft hood, senses an increase in temperature
and acts as a safety shut-off (See 'A'). It shuts
down the gas to the main burner in the unlikely
event of the appliance overheating. The HI Limit
switch will automatically reset after the appliance
has cooled down, resuming gas fl ow to the main
burner.
3.3 VENTING ACTION CHECK
A test for correct venting action must be made before the installed appliance can be left with the cus-
tomer.
Follow the procedure below:
3.3.1 Close all doors and windows in the room / start exhaust fans in the home /
turn the appliance blower off (if so equipped).
3.3.2 Set controls to "high" and light the appliance.
3.3.3 Wait 5 minutes. Light a match and hold to the front of the draft hood.
Venting action is satisfactory, if smoke and fl ames are drawn into the draft hood.
Venting action is unsatisfactory, if the smoke spills back, and the fl ame splays
outward. If venting action is unsatisfactory, turn off the appliance, wait 10 minutes
and try again. If the smoke is still not drawn into the draft hood, turn the appliance
off and check for vent blockage or restriction. If necessary, consult with a qualifi ed
inspector.
The Vent Safety or Hi Limit switches must not be adjusted or disabled.
In the event that either switch or any associated parts are exchanged, only
original manufacturer's parts may be used.
