While some of the parts should only be serviced by an authorized repairman, it is still important to understand what they are. Following is a list of the major parts of your gas light and a diagram of where they are located.

The gas light mantle is broken.

The gas light mantle is the device used to generate the bright white light common with gas lights when it is heated by a flame. Because the gas light mantle is extremely fragile, there are a number of ways for it to break. Simply touching the mantle, or exposing the gas light mantle to bugs, wind or mild vibrations could cause the mantle to break. Once broken, the only solution is to replace the gas light mantle.

It is important to keep lawnmowers and weed eaters away from the gas light post while doing yard work. Not only will the vibrations from the machinery cause the gas light mantles to break, you could also chip the paint around the gas light post and cause premature rusting.

The gas light mantle has turned black.

There are several reasons why a gas light mantle may turn black.

  • The most common reason for gas light mantles turning black is the that the burner tip has become obstructed – usually by spier webs – and needs to be cleaned. There are different ways to clean the burner tip, with both remedies requiring the removal of the gas light mantle. It is important to note that once the gas light mantle has been removed, it will need to be replaced.
  • Ensuring the gas is turned off, slide a pipe cleaner inside the burner tip, removing the obstruction.
  • Ensuring the gas is turned off, use low air pressure to blow air inside the burner tip.
  • If the mantle is too short the inside of the mantle may get too hot which will cause it to burn out. If this happens you will need to replace the gas light mantle.

Ensure you always replace the gas light mantle with a new one, following the steps for proper replacement.

Replacing the gas light mantle.

Similar to a light bulb, a broken gas light mantle will have very sharp edges. It is important to use caution when removing a broken gas light mantle to avoid getting gut by a jagged edge. When replacing a gas light mantle, follow these steps:

  • Remove the source – Before removing the broken gas light mantle, ensure that the gas supply is turned completely off and the gas light assembly has cooled completely.
  • Gain access – To gain access to the gas light mantle, you will need to remove one pane of glass, closest to the broken mantle.
  • Remove broken mantle – Being careful not to cut yourself, remove the ceramic rings that hold the gas light mantle in place. Gently lift the ceramic rings and turn them counter-clockwise until the fall from the burner tip.
  • Replace the mantle - Hang the new ceramic rings and gas light mantle from the burner tip, turning the ceramic rings slightly to lock them in place. Pull gently on the new mantle fabric to ensure it is unfolded.
  • Light the mantle – You must pre-burn the gas light mantle with the gas turned off, allowing the fabric to burn away, leaving the metal-oxide shell. Allow the gas light mantle to go out and cool off.
  • Turn on the gas – Once the gas light mantle has cooled, turn the gas supply back on and relight the mantle to ensure they are working properly. Once the gas light mantle has been replace, it is important not to touch it or it may break again. Once the gas light mantle has been tested you can reinsert the pane of glass.

Flames coming out of the gas light mantle.

There a different reasons why flames could be coming out of the gas light mantle. Things you should check for if flames a coming out of the gas light mantle include if the ceramic rings are broken, there are cracks in the burner tip or there is too much gas pressure for your gas light system.

  • If the ceramic rings on the gas light mantle are broken, they will need to be replaced. The ceramic rings are part of the gas light mantle assembly and will need to replaced as a set.
  • If there are cracks in the gas lights burner tip, you will need to remove and replace it along with the gas light mantle.
  • If there is too much gas coming through the gas line, you may need to have a gas light regulator installed. If a gas light regulator is already installed in your outdoor gas lights, adjust the regulator until the fuel feed is optimal for your gas lights.

The gas light keeps going out or won't ignite.

If your gas light keeps going out or the light is flickering, there are a variety of steps you can take to correct the issue.

  • Check the burner tip for obstructions – if the burner tip has become obstructed by lint, spiderwebs or other foreign objects, you will need to remove the gas light mantle and clean the burner tip with air or a pipe cleaner with the gas turned off. Make sure you use a new gas light mantle for replacement.
  • Check the gas light regulator – Check the installation of the gas light regulator if one is installed on your gas light. The gas light regulator should be installed by a professional and checked using accurate testing equipment. Have the installer recheck the regulator pressure and their equipment to ensure it is accurate. If the regulator is bad, have it replaced.
  • The Gas Line is too small – The gas line for standard gas lights should be no less than 3/8 inch. If it is determined that a smaller line must be used, such as inch, the line should be no longer than 8 feet in length. If the measurements are incorrect, have the line corrected by a licensed repairman.
  • Clean the bug screens – If the gas light screens are obstructed, the gas light will not get enough oxygen and the flame will be smothered. Ensure all screens on the gas light are cleared of any obstructions on the top and bottom.

It is important to note that all major repairs should be performed by a licensed service technician. Gas lights, and especially gas light mantles are very fragile and can break easily if proper care is not used during service. If you are unsure as to what the proper care steps are, contact the service person who installed the gas lights originally.
