How to Care for a Gas Log Fireplace

Gas log fireplaces are a popular alternative to traditional fireplaces.  They require little maintenance and add to the décor of a home.  There are two types of gas fireplaces to choose from: vented, which requires a chimney and heats with fire like a traditional fire place; or unvented, which requires no chimney and the logs heat up for warmth.  Both are cared for in the same manner.

Things You'll Need



  • Water

  • Extra large plastic garbage bag

  • Nylon brush

  • Vacuum cleaner

  • Scrub brush



  1. Clean your fireplace once a year to maintain safety and performance.

  2. Turn off the gas and pilot light.  Make sure the logs, burners and log stand are cool before handling. 

  3. Turn the garbage bag inside out and place the bag on the floor in front of the fireplace to protect your flooring.  

  4. Remove the gas logs, burners and log stand from the fireplace hub and place them on the garbage bag. 

  5. Clean the removed parts with a soft nylon brush to remove soot and debris.   This is also a good time to clean any fireplace tools.

  6. Vacuum the fireplace hub, vents and chimney entrance.  Clean with a scrub brush and plain water.  Do not use cleaning products as they may leave a residue which could emit toxic fumes when heated. 

  7. Replace the cleaned parts back into the fireplace hub.  Make sure all connections are secure.

  8. Light the pilot and turn on the gas to restart the fireplace.  If the fireplace doesn’t turn on and you smell gas, turn off the gas and pilot light and call a professional for assistance.

  9. Turn the garbage bag outside in, trapping removed soot and debris inside.  Empty the vacuum cleaner into the garbage bag and discard the bag in a trash bin.
