Our Napoleon gas fireplace was installed in 2002 when we bought the house. This past November it started having pilot light issues — would not stay lit, then the ignition module failed entirely. Here is the repair vs replace decision tree we went through.
The diagnosis: HVAC technician quoted $340 for a new ignition module plus $180 service call. Before replacing it, he inspected the entire unit. The valve seals were showing wear, the glass seal had hazing from a failed seal (cosmetic but indicates age), and the burner had significant rust scale. His recommendation: at 22 years, you are replacing components in a unit that will continue to need attention. A new insert would have a 10-year parts warranty.
The replace option we chose: Napoleon Ascent B46 insert, 46,000 BTU, direct vent. Fits the existing hearth opening and uses the existing B-vent flue.
- Insert supply and install (gas fitter): $4,100
- Disconnect and disposal of old unit: included
- Liner replacement (stainless liner for the B-vent run, 22 feet): $680
- Gas permit: $210
- Total: $4,990
What we turned down: The technician also quoted a linear electric fireplace — no gas permit, no liner, just a 240V circuit. $2,800–$3,400. We rejected it because we use the fireplace as primary zone heating for the living room on cold days (our house runs cool from the thermostat) and the BTU output of a gas insert can not be matched by electric.
Two months in: The new unit is significantly more efficient. Noticeably better heat output at the same thermostat setting. The flame pattern on the new burner is much more realistic than the 2002 unit.
