LIGHTING

INSTRUCTIONS

1.STOP! Read the safety information, page 14.

2.Make sure equipment shutoff valve is fully open.

3.Turn off any electric power to the appliance if service is to be performed.

4.Turn control knob clockwise to the OFF position.

5.Wait five minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Follow “B” in the safety information, page 14. If you donʼt smell gas, go to the next step.

6.Turn control knob counterclockwise to the PILOT position. Press in control knob for five (5) seconds.

7.With control knob pressed in, push down and release ignitor button. This will light pilot. The pilot is attached to the front of burner. Note: You may be running this heater for the first time after hooking up to gas supply. If so, you may need to press in control knob for 30 seconds or more. This will allow air to bleed from the gas system. If needed, keep pressing ignitor button until pilot lights. If ignitor does not light pilot, refer to Troubleshooting, page 18 or contact a qualified service person or gas supplier for repairs. Until repairs are made, light pilot with match.To light pilot with match, see Manual Lighting Procedure, page 16.

8.Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob.

•If control knob does not pop up when re- leased, contact a qualified service person or gas supplier for repairs.

Note: If pilot goes out, repeat steps 4 thru 7. Thermostat models have a safety interlock system. Wait one (1) minute before lighting pilot again.

9.Turn control knob counterclockwise to desired heating level. The main burner should light.

WARNING: Always operate manual control heaters at the locked positions. Operation between these positions may create a possible health hazard if used in a poorly ventilated room. Read owner’s manual for complete instructions.

CAUTION: Do not try to ad- just heating levels by using the equipment shutoff valve.

THERMOSTAT CONTROL

OPERATION

The thermostatic control used on these models differs from standard thermostats. Standard thermostats simply turn on and off the burner. The thermostat used on this heater senses the room temperature. The thermostat adjusts the amount of gas flow to the burner. This increases or decreases the burner flame height. At times the room may exceed the set temperature. If so, the burner will shut off. The burner will cycle back on when room temperature drops below the set temperature. The control knob can be set to any heat level between 1 and 5. Selecting the 5 setting will cause the burner to remain fully on without modulating down in most cases.
