What to do if my Monessen Hearth 624DV(ST Indoor Fireplace spark ignitor will not light pilot?
- J
  Jacob DiazAug 12, 2025
  If the spark ignitor on your Monessen Hearth Indoor Fireplace isn't lighting the pilot, here's what you can check: * Ensure the wire is connected to the ignitor. * Check for a spark at the electrode and pilot. If there's no spark and the electrode wire is properly connected, replace the pilot assembly. * Verify that the remote/manual shut-off valve is open. Low gas pressure might be due to bent or restricted lines; consult a plumber or gas supplier. * If using Propane/LPG, check the tank level and refill if necessary.

What to do if Monessen Hearth Indoor Fireplace pilot will not stay lit?
- A
  Andrew CabreraAug 16, 2025
  If the pilot light on your Monessen Hearth Indoor Fireplace won't stay lit after following the lighting instructions, consider these potential causes: * **Defective thermocouple:** Ensure the pilot flame impinges on the thermocouple. Clean or adjust the pilot for maximum flame impingement. Verify the thermocouple connection at the gas valve is fully inserted and tight. Disconnect the thermocouple from the valve and test it with a millivolt meter. If the reading is less than 15 mV, replace the pilot assembly. * **Defective valve:** If the thermocouple produces more than 15 mV, the valve may be faulty and needs replacement.
