WALL THERMOSTAT INSTALLATION INSTRUCTIONS
This kit must be installed by a qualified installer or service technician.
Your heater can be re-wired to operate with a millivolt wall thermostat by your installer. See wiring diagram
below for correct wiring.
NOTE: Do not disconnect the wire from the blocked flue switch to the "TH" terminal on the gas valve.
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 #70080 (Bulb Control Switch) from valve.
STEP 4.
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.
STEP 5.

STEP 6.
Connect second leg from the thermostat to the stripped wire coming from the blocked flue
switch. Secure this connection inside the heater cabinet.
