Adjust the height of gas log fireplace flames for comfort.

A fireplace can be a focal point for a gathering or a source of relaxation on a cold evening. Instead of burning wood in a fireplace, some homeowners choose to install fireplace logs fueled by natural gas or propane. Once lit, controlling the ambiance and amount of heat produced is a matter of adjusting the flame of the fireplace gas logs.


Step 1

Locate the gas log control knob. Look below the ceramic logs and identify the control knob, typically black with a small pointer and featuring the word "pilot."

Step 2

Light the gas logs by turning the control knob to the "pilot" setting. Rotate the knob to the left and push in to allow gas to flow to the pilot light. Press the sparker to ignite the pilot light or use a match.


Step 3

Release the control knob and allow the flame to burn for one minute. Turn the control knob to the lowest flame setting as indicated on the knob.

Step 4

Locate the switch at the front of the gas logs marked "on." Move the switch to the "on" setting to ignite the burners below the gas logs. Observe the initial flame height of the logs following ignition.


Step 5

Turn the control knob to the left to increase the flame height. Make small incremental adjustments to adjust the flame height.

Step 6

Monitor the flame height as the room warms. Reduce the flame height by turning the control knob to the right.
