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 chimney. In Canada, both
liners must extend the full length of the chimney
and be connected to both the unit and the termina-
tion kit.
2. Cut the appropriate lengths of flex duct for both the
intake and exhaust. Label both ends of the Exhaust
duct.
3. Follow the manufacturer’s instructions to attach the
ends of the duct(s) to the chimney termination kit as
appropriate.
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 termi-
nation kit.
7. Inside the fireplace, fully extend the duct and trim
any excess so that the ends hang approximately 15”
from the floor of the fireplace.
8. If the Intake duct is not attached to the chimney
termination kit:
A. Install a minimum 6 foot length flex duct for the
up the flue.
B. A METAL block-off plate must be constructed and
installed in the damper area to completely seal off
the flue from the room. Cut holes in the plate for
both the Intake and Exhaust liners.
C. A direct vent cap is required to allow fresh air into
the chimney flue and ultimately into the intake duct
to the insert.
9. Compress the ducts 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 duct you labelled
Exhaust to the Exhaust collar on the insert. Both
Intake and Exhaust collars are labelled.
11. Secure the ducts to the collars with sheet metal
screws or hose clamps. No silicone or sealant is
required.
12. Once the gas line is installed, carefully push the unit
inside the fireplace.
