What's Included
Gas fireplace vents in Gabriella, in detail
Air space between the vent and the framing
DuraVent's direct vent instructions open with a warning that a major cause of vent-related fires is failure to maintain required clearances, meaning air spaces, to combustible materials. Its Type B instructions require a 1 inch air space to combustibles around its round B-vent, regardless of pipe diameter.
Direct vent clearances vary by appliance and are set in its manual. Wherever the vent serving your Gabriella fireplace can be reached, our team checks the space around it for wood, insulation or stored items that have crept too close, and explains what has to move.
A yearly check of a B-vent
The Type B instructions say an annual inspection is required to maintain the vent's warranty. The cap, vent pipe, connector and connection to the appliance are inspected, the sealant around the flashing and storm collar is checked, a light is shone down the pipe for damage, corrosion or condensation, and disconnected sections are reconnected.
The instructions are blunt about damage. Damaged or corroded parts should be replaced immediately. Our team follows that list on B-vent fireplaces in Gabriella and prices any replacement before the fireplace is used again.
Vent problem or control problem
A gas fireplace that goes out or shuts down can have more than one cause, and the vent is only one of them. A blocked termination, a separated joint or a run with the wrong pitch can all affect how the unit burns, while the fault can just as easily sit in the unit's controls.
Our technicians check the vent path on your Gabriella fireplace first, from the termination back along the accessible route. If the vent checks out, the job moves to gas fireplace repair, and you are not charged for vent parts the system does not need.
Roof flashing and storm collar on a B-vent
Where a B-vent passes through the roof, the Type B instructions call for a hole giving a 1 inch air space, a roof flashing fitted tightly to the roof with shingles overlapping its top edge, non-hardening sealant at the flashing base and at the pipe joint, and a storm collar over that joint for a watertight seal.
Water staining on the ceiling near a vent pipe can point to that flashing or collar. Our team checks the roof penetration for the B-vent serving your Gabriella fireplace and reseals or replaces the flashing and collar where needed.
