Keeping a gas fireplace vent sound
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 a roofer joins the job
Roof terminations pass through the roof covering with flashing and a storm collar. Vent-side parts, such as the pipe, collar, sealant and cap, are within our work. The roof covering around the flashing may need a roofer, depending on the material and its condition.
We explain where our work ends and the roofer's begins before anything is started. If the roof around the vent has been leaking, the roofer may need to repair the covering after we renew the vent parts. The order is agreed in advance so the roof is not opened twice.
A cap or pipe that rattles in the wind
A rattling termination can mean loose fasteners, a damaged cap, a missing support or a joint that is working loose. The noise itself is a clue worth following, because movement can wear joints and seals over time.
We check the cap fastening, the supports and the joints nearest the noise. Loose parts are secured with the fasteners and supports the vent maker lists, and damaged parts are replaced. If the noise comes from something else, such as siding or trim near the cap, we explain it and leave that item for the right trade.
Direct-vent units rely on a sealed front
A direct-vent fireplace is sealed from the room by its glass assembly and gasket as well as by its vent. If the gasket or glass fails, the sealed system is no longer complete, even when the vent itself is sound.
During a vent visit we look at the glass assembly for obvious damage, because it is part of the same sealed system. A cracked panel or failed gasket is not repaired under venting. It is quoted under our glass replacement service, and the appliance stays off until it is fixed.

What should I do if a carbon monoxide alarm goes off?
Get everyone outside into fresh air, then call 911 from there. Stay out until the responders allow you back in, and leave the fireplace off until the vent and appliance have been inspected.
