FIREPLACE PRE-INSTALLATION PREPARATION

NOTE: LENNOX HEARTH PRODUCTS RECOMMENDS PROFES-
SIONAL INSTALLATION BY A LICENSED AND BONDED INSTALLER.
SEE YOUR DEALER FOR RECOMMENDATIONS. IMPROPER
INSTALLATION OR MIS-USE WILL VOID YOUR WARRANTY AND
CREATE A SERIOUS SAFETY HAZARD.
Remove any doors or screen materials from the fireplace opening. Re-
move the damper mechanism completely. Also remove grates or ember
catches inside the fireplace hearth. If your fireplace is equipped with a
smoke shelf or baffle and if it interferes with the installation it may be
removed. Side and rear refractory may also be removed, if necessary,
to facilitate installation. No modifications shall be done unless allowed
on the previous list. Retain all removed parts, they must be reinstalled
before the fireplace can be used in it's original condition.

INSERT PRE-INSTALLATION PREPARATION

Install the two 3" (76 mm) long bolts (with the head up) through the nuts
attached to the insert on the lower rear corner of each side. This will allow
you to level the insert when placed into the fireplace.
Measure from the front of the top surround mount to the center of the flue.
Determine if there is an alignment problem in connecting a liner from the
chimney to the insert's flue. If there is an alignment problem, connection
can be made using a short piece of stainless flex or a stainless steel offset
box (available from your dealer). Before installing the liner, make any
attachment brackets or drill any holes in the liner, offset box, or insert.
Once installed, it may be difficult or impossible to drill additional holes.

CHIMNEY LINER INSTALLATION

Remove the existing chimney cap and install a stainless steel liner into
the chimney (if a special section has been used or drilled to attach to the
insert, it must be the bottom piece). The next piece should be a dripless
slip joint; followed by the rest of the chimney liner. Fasten the chimney
at the top when it is positioned so that the slip joint will allow the lowest
piece to slide up enough to clear the insert during installation. Insulate
the top four to six feet between the liner and the chimney to prevent heat
loss. Install the cap and flash if necessary to prevent water or creosote
from entering the chimney's venting system.
From inside the fireplace firebox, attach any adapters or flue offsets and
slide the liner up as far as necessary for the bottom piece to clear the
insert during installation.
In Canada, This fireplace insert must be installed with a continuous
chimney liner of 6" or 8" diameter extending from the fireplace insert
to the top of the chimney. The chimney liner must conform to the
Class 3 requirements of CAN/ULC-S635, Standard for Lining Systems
for Existing Masonry or Factory-Built Chimneys and Vents, or CAN/
ULCS640, Standard for Lining Systems for New Masonry Chimneys.

INSTALLING THE INSERT

Place the insert into the fireplace, making sure to center it side to side.
Slide the insert in until the surround mounts are approximately 1/2" (13
mm) from the face of the fireplace where the surround panels cover.
Lower the chimney and make attachment to the insert. Level the fireplace
insert by using a 3/4" socket and a long extension and adjusting the bolts
on either side of the insert.
Install the side surround panels with the screws supplied. Push the insert
in until there is approximately a 1/4" (6 mm) gap between the back of the
surround panels and the face of the fireplace. Before installing the top
surround panel, make sure all connections are tight and that no part of
the insert or chimney is touching the firebox or chimney in the fireplace.
There must be a minimum of 1" (25mm) clearance between the fireplace
insert and the zero clearance fireplace. Install the top surround panel.
If additional support is necessary, factory punched holes in the front
corners of the bottom air chamber will accept leveling legs. Carefully
measure the distance from the hearth protection to the bottom of the
fireplace insert. Use 3/8" diameter bolts that are 1/2" (13 mm) longer that
the distance just measured. Thread a nut onto the bolt approximately 1"
(25mm). Lift the fireplace insert slightly and insert a bolt into each hole
and then thread the nut up the bolt until the front is securely supported.
Install another nut onto the bolt through the air space in the fireplace insert
and tighten securely. If desired an insert front support, Cat. No. H5296,
is available to fill the space between the insert and the hearth protection.
Install the brick and baffle as per Page 6.

POST INSTALLATION CHECKS

1. Check that all chimney pipe joints are securely fastened.
2. Be sure all roof flashings are watertight (if applicable).
FOR YOUR OWN PROTECTION AND INSURANCE PURPOSES,
HAVE YOUR CHIMNEY AND CONNECTOR PIPE INSTALLATION
INSPECTED BY YOUR LOCAL BUILDING CODE AUTHORITY OR
FIRE MARSHAL BEFORE STARTING A FIRE IN YOUR STOVE OR
INSERT. NOTIFY YOUR INSURANCE COMPANY.
FIREPLACE WARNING TAG
The factory built firebox must accept the insert without modification
other than removing bolted or screwed together pieces such as baffles
/ smoke shelf / deflectors, ash lips, glass door, screen or door tracks,
log grates, refractory or masonry lining and damper assemblies. Any
fireplace component, which is removed, must be retained so they can
be reinstalled to restore the fireplace to its original operating condi-
tion. The removal of any part must not alter the integrity of the outer
shell of the pre-engineered fireplace cabinet in any way. Any parts
removed must be replaceable. If any components are removed from
(or altered) from the existing fireplace, a metal Warning tag (shown
below) must be affixed inside the fireplace firebox, so that it shall be
visible upon removal of the fireplace insert. Note: Secure the tag using
screws or nails to the fireplace.
