STEP 1. Turn temperature control knob to “OFF” or lowest setting.
STEP 2. Turn gas valve control knob to “OFF”.
STEP 3. Disconnect wire leading from Part #80180 (Bulb Control Switch) from valve.
STEP 4. Cut the remaining wire leading from Part #80180 (Bulb Control Switch) to the blocked flue
switch, leaving its end connected to the blocked flue switch and leaving enough length to reach
the gas valve. Strip 1/2” of the insulation from the cut end of the wire.
