    Why does the flame go out when I release the control knob on my pleasant hearth Gas Heater?
    • L
      lmaldonadoAug 28, 2025
      If the ODS/pilot lights but the flame goes out when you release the control knob on your pleasant hearth Gas Heater, ensure the control knob is fully pressed in. Also, make sure to keep the control knob pressed in for 30 seconds after the ODS/pilot lights. Check that the equipment shutoff valve is fully open. A loose thermocouple connection can also cause this issue; hand tighten it until snug, then tighten a quarter turn more. If the thermocouple is damaged, replace it.

      If your pleasant hearth Gas Heater has a high yellow flame during burner combustion, it could be due to not enough air. Check the burner for dirt and debris, and clean it if necessary.

      If the burner(s) on your pleasant hearth Gas Heater do not light after the ODS/pilot is lit, it could be due to a clogged burner orifice. Clean the burner orifice.

    Why does my pleasant hearth Gas Heater produce a whistling noise when lit?
    • L
      lrodriguezSep 8, 2025
      If your pleasant hearth Gas Heater produces a whistling noise when the burner is lit, try turning the control knob to the low (1) position and let it warm up for a minute. It could also be due to air in the gas line; operate the burner until the air is removed from the line and have the gas line checked by your local propane/LP gas company. Blocked air passageways on the heater can also cause this; observe minimum installation clearances. Lastly, a dirty or partially clogged burner orifice can cause this; clean the burner.
