The Isokern Bvetto 46" (80B46) is a B-vent gas fireplace from Earthcore Isokern, vented with listed double-wall Type B gas vent and a listed cap rather than a Class A chimney. It is a fit for builders...
The Bvetto is Isokern's B-vent gas fireplace, offered here in the 46" size. As a natural-draft B-vent appliance it uses listed double-wall Type B gas vent rather than a full Class A chimney, which can simplify the chase on a gas-only build.
Vent diameter and the minimum vent height are set in the Bvetto installation manual, so the right vent depends on your ceiling and roof heights. If you are comparing sizes, a 36" Bvetto is also offered.
| Model | Bvetto 46" (80B46) |
|---|---|
| Type | B-vent gas fireplace |
| Venting | Listed double-wall Type B gas vent with listed cap |
The Bvetto must be vented with listed double-wall Type B gas vent of the diameter and minimum height in its installation manual, finished with a listed cap; see the venting recommendation on this page. Have your ceiling and roof heights ready when you plan the vent. Have it installed by a qualified installer following the manufacturer's installation manual and your local codes.
Order the Type B vent and cap with the fireplace, sized from the manual for your home. Call to confirm the burner and finishing pieces for your build.
Is the Bvetto a wood-burning fireplace?

What size vent does it need?
The diameter and minimum height are specified in the Bvetto installation manual and depend on your installation.
