TO TURN OFF GAS TO APPLIANCE

Shutting Off Heater

1. Turn control knob clockwise Clockwise to the OFF position.

Shutting Off Burner Only (pilot stays lit)

1. Turn control knob clockwise Clockwise to the PILOT position.

MANUAL LIGHTING PROCEDURE

1.Remove front panel (see Figure 10, page 12).

2.Follow steps 1 through 5 under Lighting Instructions, pages 16 and 17.

3.With control knob pressed in, strike match. Hold match to pilot until pilot lights.

4.Keep control knob pressed in for 10 seconds after pilot is lit. After 10 seconds, release control knob.

5.Replace front panel.

Check pilot flame pattern and burner flame pattern often.

PILOT FLAME PATTERN

Figure 19 shows a correct pilot flame pattern. Figure 20 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down.
