Co-linear Vent Installation
This appliance may be vented through a masonry or Class
A prefabricated chimney using a Co-linear Flexible Vent
system approved for use with a solid-fuel burning fire-
place. When installed in the manner described below, this
system can improve the performance of the appliance in
cold climate situations, as well as simplify the vent instal-
lation. See fig. 13.
These installation requirements must be followed:
1. Use the guidelines for Co-linear Vent Termination ap-
propriate for your gas type on pages 10 - 11.
1. Prior to the installation the chimney flue must be thor-
oughly cleaned and inspected by a qualified chimney
service person.
2. In a masonry chimney, a fireclay liner must be present
the entire length of the chimney.
3. Prefabricated chimneys must be UL 103 or ULC S-629
listed and have a minimum INSIDE diameter of 6
inches, (150 mm).
4. No appliance can be installed into a chimney flue serv
-
ing any other appliance of any kind.
5. THE AIR INTAKE FLEX PIPE MUST EXTEND 6 FEET BE
-
YOND THE DAMPER AREA OF THE FIREPLACE.
6. If the intake flex duct does not extend the full length
of the chimney and connect to both the unit and the
termination cap, A METAL BLOCK OFF PLATE MUST
BE CONSTRUCTED AND INSTALLED ABOVE THE UNIT
PRIOR TO THE END OF THE INTAKE FLEX AND MUST
COMPLETELY SEAL THE CHIMNEY FLUE FROM THE
ROOM.
Consult with the local code authority having jurisdic
