Quick answer
Gas fireplaces don't make creosote, but they still need a yearly inspection of the vent or chimney, the burner and pilot, the glass and gasket, the logs and the safety controls. Blocked or corroded venting can push carbon monoxide into the home.
What gets checked
- Vent or chimney for nests, debris and corrosion
- Vent termination cap outside
- Burner, pilot and thermocouple/thermopile
- Glass front and gasket seal
- Ceramic logs placed correctly (wrong placement causes soot)
- Gas connections for leaks
Warning signs
- Soot on the glass or logs
- Yellow, lazy flames instead of mostly blue
- A pilot that won't stay lit
- Headaches or nausea when the fireplace is running — turn it off, get fresh air and call for help
More questions
Do gas fireplaces need a chimney sweep?
They need a yearly inspection and cleaning of the vent when needed — not the creosote sweeping a wood fireplace needs.
