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.

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 it from the firebox. Keep the
screws for reinstallation.
2. NOTE THE EXHAUST ID ON THE VENT PANEL. Attach the
flex liners to the appropriate collars on the Vent Adaptor
and secure each using sheet metal screws or duct clamps.
Sealant is unnecessary.
3. Position the firebox under the Adaptor 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.
