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.
Oxygen Depletion Sensor Pilot (Figure 12)
When the pilot has a large yellow tip flame, clean the Oxygen Deple-
tion Sensor as follows:
1. Remove pilot from main burner assembly, see "Appliance Main-
tenance", 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.
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".

THERMOSTAT OPERATION

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