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.

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.

5. Reinstall the metal cover back over the valve (if

applicable).

6. Connect the heater’s electrical cord to an approved

electrical outlet.

7.

Set thermostat to a point above room temperature.

the heater will light.  Reset thermostat to desired room

temperature.

8. Do not exceed input rating stamped on nameplate of

appliance, or manufacturer’s recommended burner

orifice pressure for size orifice(s) used.

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.

3. Turn the knob (if applicable) on the gas control to “off”.

4. Turn thermostat to “off” or “no heat” position.

5. Disconnect the heater from the electrical supply.
