My gas fire place starts for a short time and then shuts off

1 comments:
Mr. Anderson
February 21, 2025

The HearthStone Tucson (8700) gas fireplace may start and then shut off due to several possible reasons:

1. Incorrect Air-to-Fuel Ratio – If the air shutter is not properly adjusted, the burner may not maintain a stable flame.
2. Blocked Burner Ports – If burner ports are clogged, gas flow may be restricted, causing the unit to shut off.
3. Improper Log Placement – Logs positioned incorrectly may interfere with flame travel, leading to shutdown.
4. Gas Supply Issues – If the appliance is not using the correct gas type as indicated on the rating plate, it may fail to operate properly.
5. Safety Feature Activation – If a component such as a shield, door, or safety screen has been removed and not replaced, the unit may shut off as a precaution.
6. Pilot Light Issues – If the pilot light repeatedly fails to stay lit, it may indicate a gas supply or ignition problem requiring professional inspection.

If the issue persists, discontinue use and have the unit inspected by qualified service personnel.
