Disconnect wire leading from Part #70080 (Bulb Control Switch) from valve.
Cut the remaining wire leading from Part #70080 (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.
Connect one leg of thermostat wire to the "TH/PP" terminal on the gas valve.
Connect second leg from the thermostat to the stripped wire coming from the blocked flue
switch. Secure this connection inside the heater cabinet.
