A roof cap that is too short

B-vent caps have to stand clear of the roof, and steeper roofs need taller caps. A cap that sits too low can draft poorly as wind rolls across the shingles, which shows up as spillage or a lazy flame indoors. Wind that rolls over a steep roof is exactly what the taller cap is meant to clear.

The pitch and the cap height get measured, and the vent is extended with listed pipe where needed. The roof covering around the penetration is a roofer's work. Short gas vent cap on the roof of a house in San Jose? Get it measured at (904) 920-5495.

Elbows, offsets and the total bend

Every elbow in a vent adds resistance. One maker's direct-vent manual caps the total angular change in a system at 270 degrees and limits how far the pipe may run sideways after an elbow placed right on top of the fireplace to 36 inches.

Its B-vent manual allows at most two 90-degree elbows or four 45-degree elbows per installation, counting two 45s as one 90. When we repair or reroute a vent, the elbows are counted against those limits before anything is added, and a route that would exceed them is redrawn. Every elbow also adds a joint that has to stay tight.

Cap height and roof pitch

A steeper roof needs a taller B-vent cap, because wind moving over the roof creates pressure zones near the surface. One maker's table asks for 1 foot above a roof from flat to 7 in 12, rising in steps to 2 feet over 8 in 12 to 9 in 12, and 5 feet over 12 in 12 to 14 in 12.

We measure the pitch with a gauge and the cap height from the roof, and extend the vent with listed pipe where it falls short. The shingles or roof covering around the penetration are a roofer's work, named on the estimate. The table is the maker's; the roofer's work around the pipe is separate.

Flexible venting on a direct-vent run

Flexible liner can replace rigid direct-vent pipe in some layouts. One maker allows UL 1777 listed flexible venting anywhere rigid components can be used, with all the same restrictions, clearances and allowances, and says flex kits may not be modified.

Flex can join to the end of a rigid run with the pipe maker's approved adapters, but only where the total still meets the length, height, routing and clearance rules. We use flex where it solves a routing problem and keep it within those limits, not as a shortcut past them. Flex routed badly can sag, which brings back the slope problem.

Before the vent is opened up

Is B-vent the same as direct vent?

No. B-vent carries exhaust up by natural draft from a unit that burns room air; direct vent is sealed and draws its air from outside. Each fireplace uses the one it was built for.

What if I smell exhaust right now?

Turn the unit off and get fresh air. If an alarm sounds or anyone feels ill, leave and call 911 from outside, then call us at (904) 920-5495 for the San Jose visit.
