THERMOSTAT CONTROL OPERATION
FOR IR20LPT / IR30LPT: The thermostatic control
used simply turns on and off the burner.
FOR BF20LPT / BF30LPT: The thermostatic control
used modulates the fl ame size as the temperature gets
closer to set point, then it turns off the burner upon
reaching temperature.
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
HI setting will cause the burner to remain on.

pattern is not touching thermocouple. This will cause
the thermocouple to cool. When the thermocouple
cools, the heater will shut down. If pilot fl ame pattern is
incorrect, as shown in Figure 17:
• Turn heater off (see To Turn OFF Gas to
Appliance, above.
• See Troubleshooting, pages 14-15.
