If you require a rear vent unit, check to see if rear venting has a vent cap and insulation in place. If so, remove cap and any insulation
in vent pipes, make sure flue is open completely to firebox inside. Once flue pipe has clear passages on inner and outer pipes, proceed
with vent connections.

VENT SYSTEM PREPARATION
7.
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 (Pages 45 and 46).
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 (such as a chase). There is no
requirement for inspection openings in the enclosing wall at any of the joints in the vent pipe.
