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. The gas control valve incorporates a
manual gas shut off feature. Position the
indicator on the shut off knob to PILOT.
3. Fully depress the red pilot button located on
the control valve while applying flame to the
pilot light orifice. See Fig. 12.
4. 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. On new installations it may
take about a minute for the gas to purge out
any air in the pilot line before the pilot lights.
5. Position the knob to ON.
6. Connect the heater's electrical cord to an
approved electrical outlet.
