What to do if my Duluth Forge PFS FLM24/30-1-LP Heater sparks but doesn't ignite?

If your Duluth Forge Heater is sparking at the ODS/pilot but not igniting, several factors could be the cause. First, ensure that the gas supply is turned on and the equipment shutoff valve is open. Next, check that the control knob is in the PILOT position and fully pressed in while pressing the ignitor button. If it is a new installation, or there has been a recent gas interruption, there might be air in the gas lines; in that case, continue holding down the control knob and repeat the igniting operation until the air is removed. Another potential issue could be a clogged ODS/pilot, which may require cleaning or replacement. Finally, for propane models, a depleted gas supply could be the reason; contact your local propane gas company to check.
