The Details of a Gas Chimney

A gas chimney is popular across the country, including with Nashville homeowners. Many newer homes are built with gas fireplaces, and some homeowners with wood-billed burning fireplaces consider changing for a gas fireplace. 

But one thing to keep in mind is the chimney you will need for any fireplace. 

So, what are the details of a gas chimney?

Here’s what you need to know about gas fireplace chimneys. 

Do I Need a Chimney for a Gas Fireplace?

The first thing you must know is that most gas-burning fireplaces still require a chimney! Your gas fireplace will still need a chimney for proper ventilation. Gas fireplaces can still deposit harmful corrosive substances into your home if not directed out by a chimney. To operate a gas fireplace, you’ll need a fully functioning and clean chimney. 

Cool Chimney Temperatures are a Common Problem with Gas Fireplaces

Most gas fireplaces are known for being highly efficient. However, your fireplace must create a certain amount of heat within your chimney to prevent some major issues. While you don’t want to waste heat up the chimney, some heat is necessary to keep the chimney working properly. Gas chimneys that are too cool can have issues such as:

  • Incomplete combustion: The appliance produces carbon monoxide that the chimney cannot properly exhaust due to weak draft signals. 
  • Condensation: Water vapor inside your chimney. The water is commonly very acidic and corrosive, which can greatly damage your chimney. 

Signs of a Gas Chimney Problem 

Here are the most common signs that your gas chimney has an issue:

  • Crumbling bricks 
  • Peeling wallpaper
  • Dampness or water stains on the interior or exterior walls near the chimney. 
  • Stains on the ceiling around the chimney. 
  • Eroded mortar joints. 
  • Blistered paint

Keep Your Gas Fireplace in Good Condition 

Just like a chimney for a wood-burning fireplace, your gas chimney needs to be properly maintained. You’ll need your gas chimney inspected and fully cleaned by a professional at least once a year.
