PILOT FLAME CHARACTERISTICS
The correct flame will be blue and will extend beyond the
thermocouple. 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.
