TO TURN OFF GAS

TO APPLIANCE

Shutting Off Heater

Turn control knob clockwise Clockwise to the OFF position.

Shutting Off Burners Only (pilot stays lit) Turn control knob clockwise Clockwise to the PI-

LOT position.

THERMOSTAT CONTROL

OPERATION

The thermostat control knob can be set to any comfort level between HI and LO. The ther- mostat will gradually modulate the heat out- put and flame height from higher to lower set- tings, or pilot, in order to maintain the comfort level you select. The ideal comfort setting will vary by household depending upon the amount of space to be heated, the output of the central heating system, etc.

Note: Selecting the HI setting with the control knob will cause the burner to remain fully on, without modulating down in most cases.

MANUAL LIGHTING

PROCEDURE

1.Follow steps 1 through 5 under Lighting Instructions on page 21.

2.Depress control knob and light pilot with match.

3.Keep control knob pressed in for 30 sec- onds after lighting pilot. After 30 seconds, release control knob. Now follow step 8 under Lighting Instructions, page 21.

INSPECTING BURNERS

Check pilot flame pattern and burner flame pat- terns often.

PILOT FLAME PATTERN

Figure 30 shows a correct pilot flame pattern. Fig- ure 31 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.

If pilot flame pattern is incorrect, as shown in Figure 31

•turn heater off (see To Turn Off Gas to Appli- ance, page 20 [manually-controlled models] or page 22 [thermostatically-controlled model])

•see Troubleshooting, page 25

Note: The pilot flame on natural gas units will have a slight curve, but flame should be blue and have no yellow or orange color.

BURNER PRIMARY AIR HOLES

Air is drawn into the burner through the holes in the fitting at the entrance to the burner. These holes may become blocked with dust or lint. Periodi- cally inspect these holes for any blockage and clean as necessary. Blocked air holes will create soot.

MAIN BURNER

Periodically inspect all burner flame holes with the heater running.All slotted burner flame holes should be open with yellow flame present.All round burner flame holes should be open with a small blue flame present. Some burner flame holes may become blocked by debris or rust, with no flame present. If so, turn off heater and let cool. Remove blockage, blocked burner flame holes will create soot.
