THERMOSTAT INSTALLATION
Electrical S S hock H H azard
Disconnect the electrical supply before connecting the
thermostat to the heater.
Failure to follow this warning can result in electrical
shock, leading to personal injury or death.
1. To C C onnect t t he S S eries T T ap P P lug T T hermostat K K it:
a. Connect the power cord of the heater to the
female side of the plug on the end of the
thermostat cord.
b. Plug the male side of the series tap plug on the
thermostat cord into a three-wire (grounded)
electrical outlet within the building.

Start-Up Instructions

Follow steps 1 - 8 on initial start-up after heater installation
by a qualified gas heater service person. For normal start-
up, simply turn thermostat above room temperature. The
heater will start.
1. Open all manual fuel supply valves and check for gas
leaks using approved certified leak detectors.
2. Remove the metal cover from the gas control
enclosure. (If Applicable)
3. The gas control valve incorporates a manual gas shut
off feature. Position the indicator on the shut off knob
to "pilot".
4. Fully depress the red pilot button located on the
control valve while applying flame to the pilot light.
Keep the button depressed for about 30 seconds to
allow the thermocouple to warm up so the pilot stays
lit after you release the pilot button. Once the pilot
stays lit, position the knob to "on".
ATTENTION
On new installations it may take a short period of time for the
gas to purge out any air in the pilot line before the pilot stays
lit.

Shut-Down Instructions

If the heater is to be shut down for cleaning, maintenance or
repair, follow steps 1 - 5. Otherwise, simply turn thermostat
to "off" or "no heat" for standard shut down.
1. Close all manual fuel supply valves.
2. With the heater lit, allow heater to burn off excess fuel
in gas supply hose.
