Gas fireplace venting work in Health District
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.
B-vent installation from appliance to roof
A new Type B vent runs from the appliance draft hood or collar up to a listed cap above the roof. Along the way it needs firestop spacers at ceilings, an attic insulation shield where it crosses insulation, supports, roof flashing and a sealed storm collar.
We size and lay out the route to the appliance manual and the fuel gas code, using parts from one listed Type B system. The height above the roof follows the code's rules for the roof and nearby walls. Each stage is checked before ceilings and roof are closed up.
Approving vent work before it starts
After the assessment, you receive an estimate naming the fault, the proposed vent repair, the parts and any access or restoration involved. Nothing is started, opened or ordered until you approve it. Questions about any line are welcome before you decide.
If we find something new once work begins, such as a second separated joint behind the one we were fixing, we stop and explain it. The additional work gets its own price and your approval. The final invoice then matches the scope you agreed.
Workmanship warranty on the vent work
Our workmanship warranty covers the vent work we carry out, such as fitting sections, locking joints, fitting supports and sealing penetrations. Vent parts carry their makers' own warranty terms.
If a problem appears with the vent work we did, let us know and we will return to look at it. If the new problem has another cause, such as later building work near the termination, we explain the difference before quoting anything. The estimate states which warranty covers what, so there is no confusion later.

Questions on gas vents, answered for Health District
Is a decorative shroud allowed over the termination?
Only a listed decorative cap or shroud made for your vent system. The manuals warn that decorative covers can change the clearances a cap needs, so we check the listing and the clearances before fitting one.
Do you move a termination if clearances are no longer met?
We can relocate it within the vent tables for the appliance, using listed parts. If no permitted position exists nearby, we explain the options, including changes to the nearby feature by the appropriate trade.
Can you tell whether my vent was installed correctly?
We compare what can be seen with the appliance and vent manuals, including the route, parts, supports, clearances and termination. We explain what matches, what does not and what we could not see.
