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.

Vent System Configuration

MAXIMUM TOTAL HORIZONTAL RUN = 17 FT.

MINIMUM TOTAL VERTICAL RISE = 10 FT.

MAXIMUM NO. of ELBOWS: 2 - 90o or 4 - 45o

Plan and install the vent system using the parameters shown above.

WARNING: YOU MUST NOT EXCEED

!THESE PARAMETERS.

Connect a B-Type vent component to the flue outlet collar. Look at top inside of the firebox to check that the vent pipe is attached to the unit. NOTE: It is required to first attach a straight section of vent to the unit before attaching a 90o elbow. Avoid using elbows in the vent system if possible.

A 90-degree elbow CANNOT be attached directly to u the unit. A 45o elbow can be attached directly to the unit. It must have a straight section of pipe attached to it for a MINIMUM of 4-feet before a second 450 elbow to a horizontal run (see Figure 6). The horizontal component of the vent system must

not exceed a MAXIMUM of 17-feet. The vertical component of the vent system must exceed a MINIMUM of 10-feet. Two 450 elbows to vertical can be used at any length within the 17-feet maximum horizontal component.

Continue to add vent components, until the vent run is completed.

WARNING: YOU MUST NOT EXCEED A ! TOTAL MAXIMUM HORIZONTAL RUN OF 17 FEET FOR THE ENTIRE VENT SYSTEM.

NOTE: The vent termination must be in a vertical position and the termination cap must be listed for the vent pipe used.

Consult local building code officials and codes for proper vent system installations.
