The Lennox 20115 is a direct OEM-replacement igniter rod rated at 400 watts, designed to relight your pellet stove's fire pot reliably and consistently. It replaces the widely used H8127, 12140213, and 12150213 igniters across a broad range of Whitfield and Lennox Montage pellet stove models -- making it one of the most common pellet stove repair parts on the market. If your stove fails to ignite, or takes multiple attempts before the pellets catch, a worn or failed igniter rod is the most frequent cause, and this part addresses it directly.
The igniter rod sits in the fire pot and uses resistive heating to ignite pellets at startup. Over time, repeated thermal cycling causes igniter rods to crack, burn out, or lose the ability to reach proper ignition temperature. When that happens, your stove may run the auger but fail to light, triggering an error or shutdown. Replacing the igniter rod is typically a straightforward DIY repair that restores normal automatic startup operation.
The Lennox 20115 is also catalogued as NBK Parts 20115, giving it wide availability through heating and hearth distributors. At 0.2 lbs, it ships quickly and installs without special tools in most compatible stove models.
Draws 400W to rapidly heat the fire pot and reliably ignite wood pellets at startup cycles.
5-3/4" length and 3/8" diameter -- sized to drop into the fire pot igniter port without modification.

Replaces H8127, 12140213, and 12150213 -- confirms compatibility if you have an older part number on hand.
Verify your model number against the list below before ordering. Model numbers are typically found on a data plate on the back or side of the stove unit.
Common symptoms of a burned-out igniter rod include:
A multimeter continuity check across the igniter terminals can confirm a failed element before ordering. No continuity (open circuit) confirms the rod has burned out.
