How to Change the Wick in a Comfort Glow Heater

Remove the base plate from your Comfort Glow heater and expose the fuel tank. Lift the fuel tank out of the heater and set it to one side, well away from the heater. Note that the fuel tank is not connected to anything and will slide out easily.

Run the heater until all the fuel in the lines is used, a process called "dry burn," which usually only takes a few minutes. The fire will go out when the lines are empty. Turn the heater switch off and allow it to cool.

Take the batteries out of the battery compartment on the back of the heater. This is an important safety step that keeps the heater from accidentally coming on while you are working on it.

Lift the wick ring up and off, then remove the two nuts that secure the wick. The wick ring fits around the wick and the draft pipe -- the hollow tube that holds the wick -- and serves to hold the wick firmly in place.

Slide the wick up as far as possible to reveal the positioning pin -- the small metal pin near the bottom of the wick. This pin is part of the wick and helps to ensure it is installed correctly. Push it out through the positioning hole in the draft pipe and lift the wick out of the heater.

Fit the new wick onto the draft pipe and engage the positioning pin in the hole by pushing it in until it clicks into place. Move the wick down into the heater and replace the two nuts to secure it.

Measure the distance between the wick and the draft pipe with the clearance gauge. The distance between the wick and the draft pipe should be the same all the way around, to ensure an even burn. Adjust the set screws as necessary to create even spacing. These are the small screws spaced evenly around the draft pipe that, when turned, move the pipe slightly so you can correct the spacing between the draft pipe and the wick.

Replace the wick ring over the wick. Return the batteries to the battery compartment and the fuel tank to its compartment. The fuel tank will slide securely into its compartment in only one way. Replace the fuel compartment cover to complete the project.
