How we assess and repair gas vents
What Type B vent is for
Type B gas vent is a double-wall pipe used with natural-draft gas appliances. The fuel gas code requires it to be listed to UL 441, and one vent maker lists it for draft-hood appliances and other appliances listed for Type B vent. It relies on warm gases rising, with combustion air taken from the room.
If your fireplace uses Type B vent, the route must rise to a roof termination with a listed cap. We check that the appliance manual calls for Type B vent and that the installed parts belong to one listed Type B system.
A sagging or unsupported run
Vent pipe is supported with the straps, wall bands and support plates the vent maker lists, spaced as the instructions show. The fuel gas code requires gas vents to be supported in line with the vent maker's installation instructions.
A run without enough support can sag, stress its joints and eventually separate. We check the supports along the accessible route, especially in attics and at changes of direction. Missing or failed supports are replaced with the listed parts, and any joint that has been strained is checked before the job is closed.
No manual damper in a gas vent connector
The fuel gas code does not allow a manually operated damper in the vent connector of any gas appliance. A damper that someone closes, or forgets to open, could stop the vent working entirely.
If we find a manual damper fitted in a gas vent connector, we explain the code's position and remove it as part of the vent repair. Listed automatic vent dampers and controls are a different matter, and they must be installed to their own instructions. The change is noted on your record.
The connection at the appliance collar
The first joint in the vent is at the appliance collar, where the vent attaches to the fireplace. It is often hidden behind the unit or its surround, and reaching it can mean sliding the appliance forward or removing panels.
We check the collar connection where access allows, looking at how the vent attaches and seals as the manual shows. If the collar joint cannot be reached without moving the appliance, we explain what that involves before doing it. Faults at the collar are repaired with the listed adapter or starter section.

Before you book gas vent work
Do you need to open the wall to repair a vent?
Sometimes. The manuals do not require inspection openings at joints inside walls, so concealed sections may need an access opening. We explain the access needed, and the wall restoration is listed as its own item before you approve.
Do exhaust fans affect my gas fireplace vent?
They can on a natural-draft unit. Exhaust fans, dryers and range hoods can lower indoor pressure and weaken draft. We can check the draft with them running and explain what the check shows.
What if the pipe inside the wall has come apart?
A separated joint is corrected with the listed parts and locking method once it can be reached. The appliance stays off until then. Access and restoration are priced separately from the vent repair itself.
