Venting Installation Through a
Prefabricated Fireplace
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. Attach the appropriate ends of the flex to the
chimney termination kit.
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 and cut
off the excess flex so that the liners hang ap-
proximately 15” from the floor of the fireplace.
8. If the intake flex is not attached to the chimney
termination kit: See NOTICE on page 12.
A. It is now necessary to install a minimum of a 6
foot length of flex 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.
Remember to 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. Compress the liners so that they are hanging
above the height of the fireplace opening and are
out of the way.
10. Position the insert without surround panels
half-way inside the fireplace and attach the liners
to the appropriate ports on the rear of the stove.
Be sure not to cross vent the insert.
11. Secure the liners to the ports using sheet metal
screws or hose clamps. No silicone or sealant is
required.
