MANUALLY-RESET BLOCKED FLUE SAFETY
SWITCH
This appliance is equipped with a manually-
reset blocked flue safety switch. Refer to
Figure 21 for its location. If during appliance
operation, the flame goes out (independently
of the burner on/off wall switch), it may be due
to the operation of this safety limit switch.
First allow the appliance to cool. Then reset
the safety switch by pushing the red reset
button.
This reset button is located on the back of the
limit switch, between the wire terminals (
see
Detail A of Figure 21 ).
The appliance should then relight and remain
lit. If this does not occur, turn off the appli-
ance and call a qualified service technician.
