What to do if vent is re-circulating in Napoleon BGD40-P?
Check joint seals and installation.
Why is carbon depositing on the glass, logs, or combustion chamber of my Napoleon BGD40-P?
If carbon is being deposited on the glass, logs, or combustion chamber surfaces of your Napoleon Indoor Fireplace, it could be due to several reasons: the air shutter may be blocked, so ensure the air shutter opening is free of lint or other obstructions; the flame may be impinging on the logs or combustion chamber, so check that the logs are correctly positioned, open the air shutter to increase the primary air, check the input rate by checking the manifold pressure and orifice size as specified by the rating plate values, check that the door gasketing is not broken or missing and that the seal is tight, check that both vent liners are free of holes and well sealed at all joints, and check that minimum rise per foot has been adhered to for any horizontal venting.
What causes the flames to be too large or too small in my Napoleon Indoor Fireplace?
If the flames of your Napoleon Indoor Fireplace are consistently too large or too small, it could be due to several reasons: You might be out of propane gas, so fill the tank. The spark gap might be incorrect, so ensure it's between 0.150” to 0.175” (5/32” to 11/64” approx.) from the electrode tip and the pilot burner. There might be no gas at the pilot burner, so check that the manual valve is turned on, check the pilot orifice for blockage, or replace the valve. The unit might be over-fired or under-fired, so check pressure readings.
Why do I smell exhaust fumes and get headaches when using my Napoleon BGD40-P Indoor Fireplace?
If you smell exhaust fumes in the room or experience headaches while using your Napoleon Indoor Fireplace, it may be due to appliance spillage. Ensure the exhaust bracket gasket is sealed. Also, check the door seal and relief flap seal, look for any chimney blockages, and verify that the chimney is installed according to the building code. The room might be in negative pressure, so increase the fresh air supply. Finally, inspect the cap gasket on the flue pipe assembly.
What to do if flexible vent has become disconnected from Napoleon BGD40-P?
Re-attach the flexible vent to the appliance.
How long do I need to wait for the thermocouple to cool before lighting the pilot on my Napoleon BGD40-P Indoor Fireplace?
Allow a few seconds for the thermocouple to cool.
Why does my Napoleon BGD40-P Indoor Fireplace's main burner come on when the gas knob is turned to 'ON' even when the remote wall switch is 'OFF'?
If the main burner comes on with the gas knob in the 'ON' position, even when the remote wall switch is in the 'OFF' position, the wall switch might be mounted upside down; reverse it. The remote wall switch could also be grounding; replace it. Another possibility is that the remote wall switch wire is grounding; check for a short, repair the ground, or replace the wire.
What causes the flames to be consistently too large or too small in my Napoleon BGD40-P Indoor Fireplace?
Consistently large or small flames indicate the unit is either over-fired or under-fired. Check the pressure readings. Also, perform a leak test using a soap and water solution.
How to fix a Napoleon BGD40-P Indoor Fireplace when the pilot won't light?
If the pilot won't light, start by checking if there's a spark at the pilot burner; see if you can light it with a match. Ensure the wire is connected to the push-button igniter and that the igniter is tightened. If the wire insulation is broken or frayed, replace it. If the ceramic insulator on the electrode is cracked or broken, replace the electrode. If none of these solutions work, replace the push-button igniter.
What to do if the pilot light is on but there's no gas to the main burner in my Napoleon Indoor Fireplace?
If the pilot is lit but the main burner won't ignite, even with the gas knob on ‘HI’ and the wall switch/thermostat activated, the thermostat or switch may be defective. Connect a jumper wire across the wall switch terminals; if the main burner lights, replace the switch/thermostat. Alternatively, the wall switch wiring could be defective. Disconnect the switch wires and connect a jumper wire across terminals 1 & 3; if the main burner lights, inspect the wires for defects and replace if necessary.
