Gas vent pipes, joints and terminations
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.
When the vent system is no longer made
Vent systems are sometimes discontinued, and replacement sections may become hard to find. Because the manuals prohibit mixing systems, a missing part cannot simply be swapped for a similar one from another maker.
If the original system is no longer available, we check the appliance manual for other approved vent systems. Where one is listed, the affected run may need replacing from the appliance to the termination with the new system. We explain the extent of that work before quoting it.
Vents passing through upper floors
A vent that rises through upper floors passes through ceilings and floors that each need a firestop, and it may run through closets or chases on the way. Each crossing is a place where clearances can be lost during later work.
We follow the route floor by floor where access allows and check each crossing for its firestop and clearance. Where the vent runs inside a chase, we look at how the chase is blocked. Crossings we cannot reach are noted, and access to them is offered as a separate item.
A vent route review before walls close
Another installer or a builder may be fitting your gas fireplace vent. If you want it checked before the walls close, we can review the route against the appliance manual, the vent instructions and the code's clearance table.
We look at the parts, the route against the vent tables, the supports, the firestops and the termination position. Findings are written up so the installer can act on them. We do not take over someone else's installation without agreement, but a review at rough-in costs far less than opening a finished wall.

What people ask about gas vents
What does a B-vent installation from you include?
Listed Type B pipe and fittings, with the firestop spacers, attic insulation shield, supports, roof flashing, storm collar and listed cap the vent maker specifies. The route is sized and set to the appliance manual and the fuel gas code.
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.
