  If the pilot light won't ignite, start by checking if there is a spark at the pilot burner; you can test if it lights with a match. Ensure the wire is connected to the push button ignitor and that the ignitor is tightened. If the wire insulation is broken or frayed, replace it. Should the ceramic insulator on the electrode be cracked or broken, replace the electrode. If none of these steps work, consider replacing the push button ignitor.

What should I do if the flame is impinging on the logs or combustion chamber of my Napoleon GD25-N Indoor Fireplace?
- J

  If the flame is hitting the logs or combustion chamber, ensure the logs are correctly positioned. Try opening the air shutter to increase the primary air. Verify the input rate by checking the manifold pressure and orifice size against the rating plate values. Also, confirm that the door gasketing is intact and the seal is tight. Check that both the 4" and 7" vent liners are free of holes and well sealed at all joints, and that the minimum rise per foot has been adhered to for any horizontal venting. Lastly, clean the glass with a recommended gas fireplace glass cleaner, when it's not hot, to prevent permanent marks.

What to check if there is no gas at the pilot burner of Napoleon GD25-N?

  If there's no gas at the pilot burner, first, ensure the manual valve is turned on and check the pilot orifice for any blockages. If these steps don't work, consider replacing the valve. You may need to call the gas distributor for assistance. Check pressure readings: Inlet pressure can be checked by turning screw (A) counter-clockwise 2 or 3 turns and then placing pressure gauge tubing over the test point. Gauge should read 7" (minimum 4.5") water column for natural gas or 13" (11" minimum) water column for propane. Make sure that main burner is operating on 'HI'. Outlet pressure can be checked the same as above using screw (B). Gauge should read 3.5" water column for natural gas or 10" water column for propane. Check that main burner is operating on 'HI'.

Why is the main burner flame on my Napoleon GD25-N blue, lazy, and transparent?
- S
  Shane PaulAug 27, 2025
  A blue, lazy, transparent flame could indicate a blockage in the vent; remove any blockage. In very cold conditions, ice may build up on the terminal and should be removed. Incorrect installation could also be the cause; refer to Figure 14 to ensure correct storm collar placement. Another possibility is a blocked air shutter; ensure the air shutter opening is free of lint or obstructions.
