When locating the fireplace, consideration must
be given to combustibles and final finishing.
For an example of this, see 

Figure 5 and

confine the final location of combustible finish
materials to the "Safe Zone".

DO NOT permanently place furniture or other
items such as decorative pillows within 60" of
the fireplace front face.

ASSEMBLY STEPS

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.

2. Install the chimney system.

3. Install optional 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/certi-
fied tradesman).

6. Install both door assemblies.

7. Complete finish wall material, surround and
hearth extension to your individual taste.

Study the three dimensional illustration (

Fig-

ure 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, ply-
wood, 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 ma-
terials such as brick, stone, etc., to be in-
stalled.  Shipping weights for the fireplace may
be found on page 20.

2. 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 addi-
tional support.

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

" (25 mm),

floor - 0" (0 mm), adjacent wall - 12" (305 mm),
ceiling - 37 

¹⁄₂

" (953 mm).

INSTALLING THE FIREPLACE

Step 1. Slide the fireplace into prepared fram-
ing or position fireplace in its final position and
frame later.

The fireplace may not be recessed into a com-
bustible floor. Maintain the floor to hearth clear-
ance established by the fireplace lower front
face.

Step 2. Insert the provided metal safety strips,
beneath the fireplace as illustrated (

Figures 6, 7

and 8 ). 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.

Note: Install the hearth extension only as illus-
trated.
