A. Vent System Approvals

These fireplaces are approved to use 6-inch (152mm) diameter B-type vent. B-type vent must be used when the vent system is within combustible construction.

These models may also use single wall rigid or flexible gas vent IF and ONLY IF the vent system is installed within non-combustible construction such as a masonry chimney. The same diameters noted above for B-type vent must be used for single-wall vent. See Figure 6.

The flame and ember appearance may vary based on the type of fuel burned and the venting configuration used.

B. System Components.
