What a gas service includes
- Burner, ports and logs cleaned, logs set in the right position
- Pilot, thermocouple or thermopile, and ignition tested
- Glass cleaned and gasket checked on sealed units
- Vent or flue checked for nests, blockages and damage
- Damper clamp checked on gas logs in a wood-burning fireplace
Venting and carbon monoxide
A gas flame makes carbon monoxide. When a vent is blocked by a nest or debris, exhaust can come back into the room. The Consumer Product Safety Commission reports more than 200 deaths a year from non-fire CO poisoning and urges a yearly professional inspection of fireplaces, chimneys, flues and vents. Every home with gas appliances should also have working CO alarms.
Gas log installation
| Type | How it works | Good to know |
|---|---|---|
| Vented logs | Burn in a working wood fireplace with the damper open | The most realistic flame. Most of the heat goes up the chimney |
| Vent-free logs | Burn with no chimney venting | More heat into the room. Strict sizing and use limits apply |
| Gas insert | A sealed unit inside the fireplace with its own liner | The most efficient option for real heat |

Questions about gas fireplace service
Why won't my gas fireplace pilot stay lit?
The most common causes are a dirty or failing thermocouple or thermopile, a dirty pilot assembly, or a draft blowing it out. We test each one during service.
How much does it cost to convert to gas logs?
HomeAdvisor reports averages around $1,500 for vent-free logs and higher for vented installs, plus $200–$1,000 if a gas line has to be run.
Do gas fireplaces need a chimney sweep?
Gas doesn't make creosote, but vents and flues still collect nests and debris. They need a yearly inspection and cleaning when something is found.
