How we assess and repair gas vents
Shutdowns that trace back to the vent
Some appliances shut themselves down when the vent is not working as it should. One vent maker notes that fan-assisted appliances are designed to shut down when they detect excessive pressure at the outlet, which can indicate the system is not venting properly.
A fireplace that shuts down may have an appliance fault, a supply issue or a vent problem. We check the vent route, termination and joints alongside the appliance findings. If the evidence points to the vent, the repair is quoted under venting. Appliance faults found along the way go to our repair service.
Type B vents end on the roof
The fuel gas code does not let a gas vent through an exterior wall end beside the wall or below eaves or parapets. Direct-vent and mechanical draft systems are the exceptions. A natural-draft Type B vent depends on rising warm gases and a roof termination.
If we find a natural-draft appliance vented sideways through a wall, we explain why that conflicts with the code. The answer is usually a proper vertical Type B route or an appliance designed for direct venting. The fireplace stays off until the venting matches its listing.
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.
Upfront pricing on vent work
Vent repairs can involve pipe, fittings, caps, supports, access openings and finish restoration. Our estimates price each of those as its own line, so you can see what the repair covers and what is separate.
No hidden fees are added once the job begins. A new finding that changes the scope comes to you with its price first, and nothing extra is done until you agree. Items carried by other trades, such as roof covering or siding repair, are shown as theirs rather than folded into ours.

Gas venting questions for River Run homes
What is a draft check on a natural-draft fireplace?
After warm-up, a test at the draft hood relief opening shows which way the exhaust is moving, up the vent or back out into the room. We carry it out during vent work on draft-hood appliances.
Can a new window or door near the termination cause a problem?
It can. Terminations need clearances from openable windows and doors, and a new opening can fall inside them. We measure the relationship against the manual and explain whether the termination or the opening needs to change.
Can the gas vent share a flue with a wood-burning fireplace?
No. The manuals we work from require a separate vent and prohibit venting into a pipe serving a solid-fuel appliance. The fuel gas code also calls for gas vents inside masonry chimneys to be labeled for gas appliances only.
