Attention: BF-10-1, Natural or Propane gas has a front and rear air
shutter.
BF-20-1, Propane gas only has a front air shutter.
BF-30-1, Propane gas only has a front air shutter.
Air Shutter Adjustment (Figure 7)
The air shutter on main burner is factory set at a 3/32" opening. If yellow
flames occur on main burner loosen 1/4" screw on air shutter in order to
increase air shutter opening. The slot on air shutter allows the air opening
to be increased or decreased. Tighten 1/4" screw on air shutter after air
shutter adjustment has been completed.

Cleaning Main Burner Orifice and Main Burner
1. Turn OFF gas supply to the heater.
2. Turn OFF electric supply to the heater if optional blower, SRB-18T
or SRB-30T is installed in heater.
3. Remove lower louver from casing assembly (2 screws).
4. Remove reflector from casing assembly (2 screws).
5. Inspect interior of casing assembly for accumulation of dust, lint or
spider webs. If necessary, clean interior of casing assembly with a
vacuum cleaner or apply air pressure. Do not damage any components
within casing assembly when you are cleaning.
6. Remove main burner orifice from orifice holder.
7. Apply air pressure through main burner orifice and orifice holder to
remove dust, lint or spider webs.
8. Apply air pressure into main burner to remove dust, lint or spider
webs.
9. As parts are being replaced in reverse order, check for gas leaks at
all gas connections before lower louver is replaced onto casing
assembly.
Proper Pilot Flame (Figure 8)
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.

Oxygen Depletion Sensor Pilot (Figure 9)
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 Main-
tenance", Page 6.
2. Apply air pressure through the holes in the pilot indicated by the
arrows in Figure 9. This will blow out foreign materials such as
dust, lint and spider webs.
Figure 9
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.
