Unvented Liquid Propane Fired Room Heater
8. When the pilot is lit, turn control know coun-
terclockwise to heating level. The main burner
should light.
9. To select the desired heat level, turn the
temperature setting knob counterclockwise to
between 1 & 5.
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 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.
Note: The thermostat sensing bulb measures the
temperature of air near the heater cabinet. This may
not always agree with room temperature (depend-
ing on housing construction, insulation location,
room size, open air temperature, etc.). Frequent
use of your heater will let you determine your own
comfort levels.
The LED temperature indicator measures approximate
room temperature around the heater.
Note: The LED temperature indicator DOES NOT oper-
ate with or control the thermostat setting of the heater.
TO TURN OFF GAS TO APPLIANCE
Shutting Off Heater
1. Turn control knob clockwise to the OFF posi-
tion.
2. Turn off all electrical power to the appliance if
servicing is to be preformed.
3. Turn off equipment shutoff valve.
SHUTTING OFF BURNER ONLY (PILOT STAYS LIT)
1. Turn control knob clockwise to the PILOT/IGN
position.
INSPECTING BURNER
Check pilot ame pattern and burner ame pattern
often.
PILOT FLAME PATTERN
Figure 21 show a correct pilot ame pattern. Figure 22
shows an incorrect pilot ame pattern. The incorrect
pilot ame pattern is not touching thermocouple. This
will cause the thermocouple to cool. When the thermo-
couple cools, the heater will shut down. If pilot ame
pattern is incorrect, as shown in Figure 22:
• Turn heater off (see To Turn OFF Gas to Ap-
pliance, page 11 for non-thermostat models or
page 12 for thermostat models).
• See Troubleshooting, pages 14 and 15.

BURNER FLAME PATTERN
Figure 23 show a correct burner ame pattern. Figure
24 shows an incorrect burner ame pattern. If burner
ame pattern is incorrect, as shown in Figure 24:
• Turn heater off (see To Turn OFF Gas to Ap-
pliance, page 11 for non-thermostat models or
page 12 for thermostat models).
• See Troubleshooting, pages 14 and 15.
