Prefabricated Fireplace Vent Procedure
1. Measure height of the chimney to fireplace
opening. Determine if both the intake and
exhaust will be extended to the top of the
chimney.
2. Cut the appropriate lengths of flex for both the
intake and exhaust.
3.
If the intake flex will be attached to the chimney
termination kit:
Attach the appropriate ends of
the flex to the chimney termination kit.
CAUTION: AVOID CROSS-VENTING THE FLEX
PIPE. Label the end of the exhaust pipe to ease
identification inside the house.
4. Drop the liners down the chimney from the top
and rest the termination kit atop the chimney.
5. Seal the chimney termination kit to the top of the
chimney pipe with high temperature sealant.
6. Secure the appropriate DIRECT VENT CAP to the
termination kit.
7. Inside the fireplace, fully extend the flex duct
and cut off any excess so that the liners extend
approximately 15” from the floor of the fireplace.
8.
If the intake flex is NOT attached to the chimney
termination kit: See VENT NOTICE on page 12.
A. It is necessary to install a minimum 6 foot
length of flex pipe into the flue for the intake air.
B. A METAL damper block off plate must be
constructed and installed in the damper area to
completely seal off the flue from the room. Cut
holes for both the intake and exhaust liners in the
block off plate.
C. A direct vent cap is still required to allow fresh
air into the chimney flue and ultimately into the
intake flex and insert.
D. Attach the Fireplace Conversion Notice to the
back of the fireplace if appropriate.
9. Backer Plates or the Cast Iron Overlay panel must
not block or seal any ventilation openings on the
prefabricated fireplace.

ACCORDANCE WITH THESE DIAGRAMS OR FAILURE TO

6.3 Vent Connection
Wear Safety Gloves!
Test fit the firebox in its final position to confirm it is
level and plumb before connection to the vent system.
A leveling bolt is located at each corner in the base of
the firebox to allow a maximum 1/2” adjustment for
hearth irregularities. Front bolts are accessible in each
side compartment through the fireplace front. Tip
the firebox forward to adjust the rear bolts out of the
base.
1. Refer to fig. 6.3. Remove the Lock Screw from the
Vent Adaptor Panel and detach the panel from the
firebox. Retain the screw for reinstallation.
2. Attach the ends of the flex liners to the appropriate
collars on the Vent Panel and secure each with
screws or duct clamps. Sealant is unnecessary.
3. Position the firebox under the vent collar panel and
use the Latch Tool to engage the panel with the
associated pins on the firebox Vent Manifold.
4. Reinstall the Lock Screw to secure the adaptor
panel to the firebox.
5. Push the insert firebox fully into the final position
.
Do not install the Backer Plate or Overlay Frame
until all other assembly and system checks are
completed.
