How gas fireplace venting is handled in Forest City

A vent listed with the appliance

A direct vent pipe is not a generic part. DuraVent's DirectVent Pro instructions explain that the venting, in combination with the gas appliance, has been tested and listed as a system by a major testing agency, and they tell installers to check the appliance's rating plate and manual to confirm the vent is approved for that brand.

We make the same check on your Forest City fireplace. The vent brand and model on the job must be one the appliance maker approves, and if the existing vent is not, we explain what that means before any repair is quoted.

The pitch of a horizontal vent run

Horizontal vent runs need the right pitch. DuraVent's direct vent instructions require a horizontal run to be level or rise 1/4 inch for every foot toward the termination, and never to run downward, because a downward slope can trap heat and become a possible fire hazard. Its Type B instructions ask lateral runs to slope upward away from the appliance by at least 1/4 inch per foot.

A run that has sagged since installation can lose that pitch. Our technicians check the slope along the accessible run serving your Forest City fireplace and add support or correct the pitch where it has dropped.

Firestops where the vent passes through

Where a vent passes through a floor or ceiling, a firestop closes the opening around the pipe while holding the required clearance. DuraVent's direct vent instructions require firestops at each floor and ceiling, and a wall thimble or wall firestop may be required by the appliance maker where the vent goes through a wall.

In the attic or ceiling space above your Forest City fireplace, our team checks that the firestops are in place and that the vent sits properly in them. A missing or damaged firestop is priced on its own line.

Planning a vent route for a new fireplace

Every direct vent appliance has limits on horizontal run, vertical rise and the number of elbows. DuraVent tells installers to check the appliance manual for those restrictions, and its Type B instructions advise keeping turns and lateral runs to a minimum, noting that a 45 degree turn is preferable to a 90 degree turn.

At your Forest City home our team lays out the route from the fireplace location to a termination that meets its clearances, checks it against the appliance's venting table and shows you the route before work begins. Permits are discussed where the local authority requires them.
