APPLIANCE OPERATION

Step 9. Checking the System – With gas line
installed run initial system checkout before
closing up the front of the unit. Follow the
pilot lighting instructions provided in the Hom-
eowner's Care and Operation Instructions. For
piezo ignitor location see Figure 18 (millivolt
appliances only).
Note: Instructions are also found on the pull
out lighting instructions label attached to the
gas control valve.
When first lighting the appliance, it will take
a few minutes for the line to purge itself of
air. Once purging is complete, the pilot and
burner will light and operate as indicated in the
instruction manual.

MANUALLy-RESET BLOCKEd FLUE SAFETy
SWITCH
This appliance is equipped with a manually-reset
blocked flue safety switch. Refer to Figure 19
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 opera-
tion 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 19 ).
The appliance should then relight and remain
lit. If this does not occur, turn off the appli-
ance and call a qualified service technician.
