Keeping a gas fireplace vent sound
Leaks at a roof penetration
A vertical gas vent passes through the roof with flashing and a storm collar. One vent maker calls for a ring of nonhardening high-temperature sealant, such as silicone, around the pipe at the top of the storm collar to keep the roof watertight.
A ceiling stain near a vertical vent can mean the collar, sealant or flashing has failed. We check them where the roof can be reached safely and explain what we find. Vent-side repairs are quoted by us. If the roof covering around the flashing needs work, a roofer handles it.
Replacing a termination cap with the listed cap
A damaged or missing termination cap is replaced with the cap listed for your vent system. The fuel gas code requires roof terminations to end with a listed cap or roof assembly, and direct-vent terminations are part of the system the appliance was tested with.
We identify the system from labels and the appliance manual, order the listed cap and fit it as the instructions show. The joints nearest the cap and the seal to the wall or roof are checked at the same time. The replacement is recorded with its part number.
Outside air kits on natural-draft units
An outside air kit, where the model accepts one, brings combustion air in from outdoors rather than from the room. The maker of one such model recommends the kit and makes it mandatory under negative pressure, to support performance and to help stop combustion gases spilling.
If a draft check shows spillage and the house runs at negative pressure, we look at whether an outside air kit is listed for your model. Its inlet position and route are planned like any other vent part. The kit's control, which can be closed when the fireplace is not in use, is shown to you afterwards.
Checking vent work someone else did
If your vent was repaired or extended before and the fireplace has not behaved well since, tell us what was done. Mixed parts, unlisted caps, missing supports or a route outside the tables are common findings after hurried work.
We compare the installed vent with the appliance manual and the vent instructions and explain any differences without judging whoever did the work. The estimate covers what is needed to bring the vent back to its listed arrangement, section by section, so you can see where each cost comes from.
What your gas vent estimate covers
- Supports, straps and wall bands
- Separate vent confirmed for the appliance
- Clearance to later decks, fences and additions
- Decorative shroud listing confirmed
Questions on gas vents, answered for Miami Shores
Will you check the roof flashing around a vertical vent?
Yes, as part of the vent route. We look at the flashing, storm collar and sealant around the pipe where the roof can be reached safely. Roofing work beyond the flashing is referred to a roofer and priced by them.
What records do I get after vent work?
A written record of the work that lists the appliance, the vent maker and system, and the route. It also covers the parts replaced, the checks made and anything that stayed concealed or outside the scope.
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.
