Gas fireplace vent repair and installation in Baldwin Park

Why a B-vent loses its draft

Poor draft has a long list of venting causes in one B-vent fireplace manual, and each one points at a different repair. Our pros work through it in order, since the fix for a short vent is nothing like the fix for a blocked one.

The list below comes from that manual. Several causes can exist on the same house, which is why we check them all before quoting.

• Too much offset or too many elbows
• A vent that is too short or too close to the roof line
• A blockage restricting the pipe
• The wrong vent type or the wrong size
• More than one appliance on one vent

Flames that die while the fireplace is running

A fireplace that lights fine and then goes out can have a vent fault or a control fault, and the two call for very different repairs. One direct-vent manual lists the inner vent pipe, the pitch of horizontal runs and the vent cap as venting causes when pilot and burner go out together.

Pilot, thermocouple and valve faults belong to gas fireplace repair. Our technicians check the vent and the controls on the same visit, so you do not pay for a new valve when the real problem is a cap.

Before the first fire of the cool season

A fireplace that has been off for months deserves a short check before the first evening it runs. The cap may hold leaves or nesting, the glass latches may have loosened and the yard may have changed.

Our pros clear and check the cap, confirm the glass is seated and secured, look at the reachable joints and run the fireplace long enough to watch the flame settle. It is a quick visit that often saves a service call later in the season.

Add-ons the listing does not include

A gas fireplace is tested as a complete package. One manual says not to use a blower insert, heat exchanger insert or any other accessory not approved for that fireplace, and not to modify the fireplace under any circumstances.

The same manual lists unauthorized modification of the venting system as an action that voids the venting warranty. Our technicians remove parts that do not belong, restore the listed configuration and tell you which accessories your model does allow.

Natural gas or propane on the rating plate

Every gas fireplace is built for the gas named on its rating plate. One direct-vent manual says its unit is not convertible to another gas unless the maker's approved conversion kit is used.

A fireplace running on the wrong gas behaves badly no matter how good the vent is. Our pros confirm the gas type on the plate against the supply before any vent diagnosis, since that check takes a minute and rules out a costly wrong turn.
