Note: The following steps represent the normal
sequence of installation. Each installation is
unique, however, and might require a different
sequence.
1. Position firebox prior to framing or into
prepared framing.
. Install the chimney system.
3. Install outside combustion air kit.
4. Plumb gas line if a decorative gas appliance
will be used. (Gas connections should only
be performed by an experienced, licensed/
certified tradesman).
5. Install both “All-Glass TM ” door assemblies.
6. Complete finish wall material, surround and
hearth extension to your individual taste.
7. Inststall the glass doors provided.
Study the three dimensional illustration (Figure
1) to get a general idea of each element of your
fireplace system.
Pre-InsTallaTIon noTes
The fireplace may be installed directly on a
combustible floor or raised on a platform of
an appropriate height. Do not place fireplace on
carpeting, vinyl or other soft floor coverings. It
may, however, be placed on flat wood, plywood,
particle board or other hard surfaces. Be sure
fireplace rests on a solid continuous floor or
platform with appropriate framing for support
and so that no cold air can enter the room from
under the fireplace.
The fireplace may be positioned and then the
framing built around it, or the framing may be
constructed and the fireplace positioned into
the opening.
Usually, no special floor support is needed for
the fireplace, however, to be certain:
1. Estimate the total weight of the fireplace
system including chimney and surround
materials such as brick, stone, etc., to be
installed. Shipping weights for the fireplace
may be found on Page 7.
The firestop thimble supplied with the unit must
be used on a manufactured home installation.
The firestop thimble must extend completely
though the roof cavity to the outermost plane
of the roof (See Figures 21, 22 and 23).
Maintain 1" clearance between the thimble and
the chimney.
If you plan to raise the fireplace and hearth
extension, build the platform assembly then
position fireplace and hearth extension on
top. Secure the platform to the floor to prevent
possible shifting.
clearances
Minimum clearance to combustibles for the
appliance is as follows: sides - 1/2" (12.5 mm),
floor - 0" (0 mm), adjacent wall - 18" (457 mm),
ceiling - 37-1/2" (953 mm).
Note: Install the hearth extension only as il-
lustrated.

The structural integrity of the

InsTallInG The fIrePlace
step 1. Slide the fireplace into prepared framing
or position fireplace in its final position
and frame later.
The fireplace may not be recessed into a
combustible floor. Maintain the floor to hearth
clearance established by the fireplace lower
front face.
step . Insert the provided metal safety strips,
beneath the fireplace as illustrated
(Figures 6 and 7). The safety strips
should overlap 1/2" for continual
coverage of the floor.
Note: Safety strips are not required when fire-
place rests on a noncombustible surface.
. Measure the square footage of the floor space
to be occupied by the system, surrounds and
hearth extensions.
3. Note the floor construction, i.e. 2 x 6’s, 2 x
8’s or 2 x 10’s, single or double joists, type
and thickness of floor boards.
4. Use this information and consult your local
building code to determine if you need ad-
ditional support.
