Fire Risk
When lining air-cooled factory-built chimneys:.
• Run approved chimney liner
• Re-install original factory built chimney cap ONLY
• DO NOT block cooling air openings in chimney
• Blocking cooling air will overheat the chimney
WARNING
E. Prefabricated Metal Chimney (Cont’d)
To maintain the functionality of the fireplace’s chimney
system you may use a Simpson Dura-Vent DuraLiner
Slip Hanger, Part # 4671, and attach to the bottom of the
fireplace chimney cap to support the liner. You have two
options to completing the installation.
Option one - Not required to use liner cap:
Re-attach the existing top of the chimney cap.
Option two - Using liner cap:
Re-attach the existing top of the chimney cap and install
a new storm collar and a new liner cap.

F. Installation Into A Masonry Fireplace
The insert must be installed as per the requirements of
your local inspection authority. It is recommended to use
a full liner as it is the safest installation and provides the
most optimum performance. Your retailer should be able to
help you decide which system would be the best for your
application.
The use of this connection method not only increases
the safety of your insert by directing the hot gases up the
flue, but will also help increase the unit’s efficiency and
decrease creosote deposits in the chimney.
When a connected flue or liner is in use, the insert is able
to “breathe” better by allowing a greater draft to be created.
This great draft can decrease problems such as difficult
start-ups, smoking out the door and dirty glass.
G. Installation Into A Factory Built Fireplace
1. When installed in a factory built fireplace, a full stainless
steel rigid is mandatory, for both safety and performance
purposes. When a flue or liner is in use, the insert is able
to breathe better by allowing a great draft to be created.
The great draft can decrease problems such as difficult
start-ups, smoking out the door, and dirty glass.
2. In order to position the flue liner, the existing rain cap
must be removed from your chimney system. In most
cases the flue damper should also be removed to allow
passage of the liner.
3. In most cases opening the existing spark screens fully
should give enough room for the insert installation. If it
does not, remove and store.
4. If the floor of your fireplace is below the level of the
fireplace opening, adjust the inserts leveling bolts to
accommodate the difference. When additional shimming
is required, use non-combustible masonry or steel shims.
5. Measure approximately the alignment of the flue liner
with the position of the smoke outlet hole on the insert
to check for possible offset. If an offset is required, use
a proper stainless steel unit available with the chimney
liner.
6. Once the above items have been checked, slide your
insert into position after first positioning the flue liner
and offset if required. (Re-install raincap at completion
of installation).
