Can the vent for a first-floor fireplace run up through a closet or room on the second floor?
Yes — a first-floor gas fireplace commonly routes its vent straight up through the floors above, but it has to be enclosed in a fire-rated chase, hold its required clearance to combustibles the whole way, be firestopped at each floor, and terminate above the roof per code and the manufacturer's manual. It can't sit as exposed pipe in a bedroom or closet.
How the vertical run works
Absolutely — a first-floor gas fireplace routing its vent straight up through the second floor is standard. What the code and the manufacturer's manual require is that the pipe stay fully enclosed in a fire-rated chase or framed enclosure, hold its listed clearance to combustibles every inch of the way, get firestopped where it passes through each floor, and terminate above the roofline. That means the section passing a second-floor closet or bedroom is boxed in — never exposed pipe sitting out in living space.
When a sidewall run is simpler
If your first-floor fireplace sits on an exterior wall, a horizontal direct-vent run straight out the sidewall is often the cleaner, cheaper path — no second-floor chase to build. The vertical-through-the-house route is what we use when the fireplace is on an interior wall or the design calls for it. Direct-vent systems have limits on total horizontal run and the number of elbows, so which way the pipe goes gets planned around your floor plan, not guessed at.
The framing and the finish
Running vent through an upper floor means coordinating framing — we build or box the chase, keep the clearances, and seal the firestops so the assembly stays fire-rated. Done right, all you see upstairs is a closet or a boxed corner; done wrong, it's a fire and inspection problem. This is one job with one accountable company: appliance, venting, gas line, permit, inspection. Call (828) 545-0525.
