1. 2. 3. 4. 5. 6. 7. 8. STOP! Read the safety information above. Set thermostat (gas control knob) to lowest setting. Turn off all electric power to the appliance (if applicable). Push in gas control knob slightly and turn clockwise to "OFF". Do not force. Wait ten (10) minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Follow "B" in the safety information above. If you don't smell gas, go to the next step. Find pilot - the pilot is attached at the bottom of the burner assembly . Turn gas control knob counterclockwise to "PILOT." Push in gas control knob all the way and hold in. Repeatedly push the piezo ignitor button until pilot is lit (or use a match to light pilot). Continue to hold the control knob in for about one (1) minute after the pilot is lit. Release knob and it will pop back up. Pilot should remain lit. If it goes out, repeat steps 4 through 8. • If knob does not pop up when released, stop and immediately call your service technician or gas supplier. • If the pilot will not stay lit after several tries, turn the gas control knob to "OFF" and call your service technician or gas supplier. 9. Attention! Gas control has an INTERLOCK latching device. When the pilot is initially lit and the safety magnet is energized (pilot stays "ON") the INTERLOCK latching device becomes operative. If the gas control is turned to the "OFF" position or gas flow to the appliance is shut off, the pilot cannot be relighted until the safety magnet is de-energized (approximately 60 seconds). There will be an audible "click" when the safety magnet in the gas control is de-energized. Pilot can now be relighted. Repeat steps 4 through 8. 10. Turn gas control knob counterclockwise to "HI". 11. Turn on all electric power to appliance (if applicable). 12. Set thermostat (gas control knob) to desired setting from "HI" to "LO". LIGHTING INSTRUCTIONS 1. 2. TO TURN OFF GAS TO APPLIANCE Set thermostat (gas control knob) to lowest setting. Turn off all electric power to appliance if service is to be performed (if applicable). 3. Push in gas control knob slightly and turn clockwise to "OFF". Do not force. Page 10 16943-5-0806 MAIN BURNER FLAME CHARACTERISTICS Piezo Pilot Ignitor Instructions Depressing the ignitor button completely causes a spark to occur at the pilot. To light the pilot, it is important that the electrode be 1/8" (3mm) from the pilot. The spark must occur at the point the pilot flame hits the thermocouple. On a new installation with air in the gas line, it is suggested that a match be used. The match will light the pilot faster than the piezo under this condition. There will be a short blue inner flame with a much larger, lighter blue, secondary flame. The burner flame may have a small yellow tip when hot. Dust in the combustion air will produce an orange or red flame. Do not mistake the orange or red flame for an improper yellow flame. Clean main burner by applying compressed air into ports and throat of main burner. Air Shutter Adjustment (Figure 10) 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. Figure 9 Attention: BF-10, Natural or Propane gas has a front and rear air shutter. BF-20, Propane gas only has a front air shutter. BF-30, Propane gas only has a front air shutter. Figure 10 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. 16943-5-0806 Page 11 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 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.
