Installation Instructions and Owner’s Manual

Unvented Natural Gas Fired Room Heater

• 

If pilot does not stay lit, refer to Troubleshoot

-

ing, pages 14 & 15. Also, contact a qualified 

service person of gas supplier for repairs. 

• 

If control knob does not pop up when released, 

contact a qualified service person or gas sup

-

plier for repairs.

8.

 

  When the pilot is lit, turn control knob 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 IR20NGT / IR30NGT:

 The thermostatic control 

used simply turns on and off the burner. 

FOR BF20NGT / BF30NGT: 

The thermostatic control 

used modulates the flame 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 flame pattern and burner flame pattern 

often.

PILOT FLAME PATTERN

Figure 21 show a correct pilot flame pattern. Figure 22 

shows an incorrect pilot flame pattern. The incorrect 

pilot flame pattern is not touching 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 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 flame pattern. Figure 

24 shows an incorrect burner flame pattern. If burner 

flame 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.
