HEATER

4.Wait five (5) minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Follow “B” in the safety in- formation, page 16. If you don’t smell gas, go to the next step.

5.Press in control knob and turn counter-

clockwise C-clockwiseto the PILOT posi- tion. Keep control knob pressed in for five (5) seconds (see Figure 23, page 16).

•If control knob does not pop out when released, contact a qualified service person or gas supplier for repairs.

Note: You may be running this heater for the first time after hook- ing up to gas supply. If so, the con- trol knob may need to be pressed in for 30 seconds. This will allow air to bleed from the gas system.

6.With control knob pressed in, press and release ignitor button. This will light pilot. The pilot is attached to the front burner. If needed, keep pressing igni- tor button until pilot lights.

Note: If pilot does not light, contact a qualified service person or gas sup- plier for repairs. Until repairs are made, light pilot with match. To light pilot with match, see Manual Lighting Procedure.

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

Note: If pilot goes out, repeat steps 3 through 7.

8.Push in and turn control knob coun-

terclockwise C-clockwiseto the HIGH position. Both burners should light. Set control knob to desired setting.

VARIABLE CONTROL

OPERATION

The variable control valve can be set to any heat setting and flame height desired between high and low by simply turning the control knob until that setting is at- tained. Even the lowest setting provides realistic flames and glowing embers from two burners. Selecting higher settings pro- duces greater heat output. This results in increased heating comfort.

WARNING: Do not operate heater between pilot and high.

CAUTION: Do not try to adjust heating levels by using the manual shutoff valve.

MANUAL LIGHTING

PROCEDURE

1.Follow steps 1 through 5 under Light- ing Instructions, page 16.

INSPECTING

BURNERS

Check pilot flame pattern and burner flame patterns often.

PILOT FLAME PATTERN

Figure 25 shows a correct pilot flame pattern. Figure 26 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touch- ing the thermocouple. This will cause the thermocouple to cool. When the thermo- couple cools, the heater will shut down.

If pilot flame pattern is incorrect, as shown in Figure 26

•turn heater off (see To Turn Off Gas to Appliance, page 16 [Thermostat-Con- trolled Models] or page 17 or [Variable Manually-Controlled Models])

•seeTroubleshooting, pages 19 through 21
