Venting through a Masonry 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 chim-
ney.
2. Use tin snips to 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 flue with high temperature sealant.
6. Secure the appropriate DIRECT VENT CAP to the
termination kit.
7. Inside the fireplace, fully extend the flex liner pipe
and cut off the excess so that the liners hang
approximately 15” from the floor of the fireplace.
8. If the Air Intake pipe will not be attached to the
chimney termination kit: (See NOTICE on page 10. )
a. It will be necessary to install a minimum length
of 6 ft. flex pipe up into the flue.
b. A metal damper block off plate must be
constructed and installed in the fireplace damper
area to completely seal off the flue from the
room. Cut holes in the plate for both the intake
and exhaust flex pipes.
c. A direct vent cap is required to bring fresh air
into the chimney flue and Air Intake flex pipe.
d. Compress the liners so that they are hanging
out of the way above the fireplace opening.
e. Attach the Fireplace Conversion Notice to the
back of the fireplace if appropriate.
9. 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 these connections. Secure
the liners to the ports using sheet metal screws or
hose clamps. No silicone or sealant is required.
