VENT SYSTEM PREPARATION

Select a Horizontal or Vertical Vent System
1.
With the fireplace secured in the framing, determine the vent route and identify the exterior termination location.
The following sections describe vertical (roof) and horizontal (exterior wall) vent applications. Use only approved
vent components. See Pages 28 - 29 (vertical) and Pages 33 - 35 (horizontal).
NOTE:
This fireplace must be vented directly to the outside.
WARNING
The vent system may not service multiple appliances, and must never be connected to a
flue serving a separate solid fuel burning appliance.
NOTE:
The vent pipe is tested to be run inside an enclosed wall. There is no requirement for inspection openings in
the enclosing wall at any of the joints in the vent pipe.

Bend out the appropriate nailing flanges for the drywall / finish material to be used (Figure 10). Nailing flanges
are provided for:
• 1/2”, and
• 5/8” framing depths.

Secure the fireplace to the side framing members using the unit’s nailing flanges —one top and bottom on each
side of the fireplace front (Figure 10). Use 8d nails or the equivalent.
