SWITCH
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' below). 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.
A test for correct venting action must be made before the installed appliance can be left with the cus-
tomer.
Follow the procedure below:
2.3.1
Close all doors and windows in the room / start exhaust fans in the home /
turn the appliance blower off (if so equipped).
2.3.2 Set controls to "high" and light the appliance.
2.3.3 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 out-
ward. 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.
