PILOT FLAME CHARACTERISTICS

The correct flame will be blue and will extend beyond the thermo- couple. The flame will surround the thermocouple just below the tip. A slight yellow flame may occur where the pilot flame and main burner flame meet.

Figure 11

Oxygen Depletion Sensor Pilot (Figure 12)

When the pilot has a large yellow tip flame, clean the Oxygen Depletion Sensor as follows:

1.Remove pilot from main burner assembly, see "Appliance Maintenance", Page 13.

2.Apply air pressure through the holes in the pilot indicated by the arrows in Figure 12. This will blow out foreign materials such as dust, lint and spider webs.

Figure 12

Warning:

Never use needles, wires, or similar cylindrical objects to clean the pilot to avoid damaging the calibrated ruby that controls the gas flow.

THERMOSTAT OPERATION

To ignite main burner, rotate gas control knob counterclockwise toward HI setting. To shut down main burner, rotate gas control knob clockwise toward LO setting.

BF-10

The gas control has an input of 10,000 Btu/HR (2.9 KW/H). The hydraulic thermostat bulb is located at the casing assembly bottom.

BF-20

The gas control modulates from a minimum input of 8,500 Btu/HR (2.5 KW/H) (LO setting) to a maximum input of 20,000 Btu/HR (5.9 KW/H) for LP gas (HI setting) or 18,000 Btu/HR (5.3 KW/H) for Natural Gas (HI setting). The hydraulic thermostat bulb which is located at the casing assembly bottom adjusts the main burner flame between minimum input and maximum input.

BF-30

The gas control modulates from a minimum input of 8,500 Btu/HR (2.5 KW/H) (LO setting) to a maximum input of 30,000 Btu/HR (8.8 KW/H) (HI setting). The hydraulic thermostat bulb which is located at the casing assembly bottom adjusts the main burner flame between minimum input and maximum input.

Note: When the hydraulic thermostat bulb is "satisfied" the main burner flame will shut "OFF" with the pilot flame remaining "ON".

The LO and HI setting has temperature range of approximately 55°F (12.78°C) to 90°F (32.22°C) , respectively. This is the temperature at the hydraulic thermostat bulb not the room temperature. The owner is advised to determine the particular heat setting that is desired for comfort, as heating requirements are different for every owner.

Attention: If the owner does not want the main burner to ignite and turns the gas control knob to the Lo setting, the main burner will still ignite if the temperature at the hydraulic thermostat bulb drops to 55°F (12.78°C).

If no heat is desired, turn the gas control knob to the PILOT position.
