    What to do if Monessen Hearth Gas Heater sparks but doesn't ignite?
    • N
      Nicole TaylorAug 23, 2025
      If your Monessen Hearth Gas Heater is sparking but not igniting, it could be due to a few reasons. First, check if the gas supply is turned on or if the manual shutoff valve is open. Ensure the control knob is in the PILOT position and pressed in while in that position. If there's air in the gas lines from a recent installation, continue holding down the control knob and repeat the igniting operation until the air is removed. Also, the ODS/pilot might be clogged (in this case replace ODS/pilot assembly or get it serviced), or the gas regulator setting might not be correct, so check the incoming pressure and replace the gas regulator if needed.

    Why does my Monessen Hearth Gas Heater smell?
    • C
      christopher52Aug 27, 2025
      Your Monessen Hearth Gas Heater might be producing unwanted odors because it's burning vapors from paint, hair spray, glues, or other similar products. Another cause could be a gas leak or initial burn off. To address this, ventilate the room and stop using odor-causing products while the heater is running. If it is a gas leak, locate and correct all leaks. If it's due to initial burn off, ventilate the room and turn the unit on high until the odor is gone; it should dissipate after about six hours of continuous use.

    How to fix no spark at pilot light on Monessen Hearth Gas Heater?
    • S
      Stacey DouglasAug 27, 2025
      If there's no spark at the ODS/pilot when you press the ignitor button on your Monessen Hearth Gas Heater, the ignitor electrode might be positioned wrong or broken, in which case you should replace the ignitor. It could also be that the ignitor electrode is not connected to the ignitor cable, so reconnect it. The ignitor cable might be pinched or wet; free it if pinched or replace it if wet. Finally, the ignitor cable could be broken, or the piezo ignitor could be bad, so replace the ignitor cable or the piezo ignitor.

      If your Monessen Hearth Indoor Fireplace doesn't turn on, it might be due to a few reasons. First, ensure the transmitter is properly paired with the receiver. Second, if the transmitter's temperature reading exceeds 99°F and displays "HI" on the LCD, move the transmitter to a cooler location until the temperature decreases below 99°F. Lastly, confirm that the distance between the transmitter and receiver is less than 30 feet.

      Anthony PearsonSep 6, 2025

      Lori SnyderSep 3, 2025
      If, when you press the ignitor button on your Monessen Hearth Indoor Fireplace, there's a spark at the ODS pilot but no ignition, check that the gas supply is turned on and the manual shutoff valve is open. Ensure the control knob is in the PILOT position and pressed in while in that position. If there's air in the gas lines from installation, continue holding down the control knob and repeat the igniting operation until the air is removed. If the ODS/pilot is clogged, replace the ODS/pilot assembly or get it serviced. Finally, verify that the gas regulator setting is correct by checking the incoming pressure and replacing the gas regulator if necessary.
