THERMOSTAT
CONTROL
OPERATION
The thermostat control knob can be set to any comfort level between Hi and Lo. The thermostat will gradually modulate the heat output and flame height from higher to lower settings, or pilot, in order to maintain the comfort level you select. The ideal com- fort setting will vary by household depend- ing 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 re- main fully on, without modulating down in most cases.
MANUAL LIGHTING
PROCEDURE
1.Follow steps 1 through 5 under Light- ing Instructions, page 13.
2.Depress control knob and light pilot with match.
3.Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob. Now follow step 8 in Lighting Instructions, page 13.
INSPECTING
BURNERS
Check pilot flame pattern and burner flame patterns often.
PILOT FLAME PATTERN
Figure 24 shows a correct pilot flame pat- tern. Figure 25 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 25
•turn heater off (see To Turn Off Gas to Appliance, page 13)
•seeTroubleshooting, pages 16 through 18
