This list of specific instructions will help you make certain
that every installation operation is done correctly. Complete
the installation steps in the sequence shown.
LOCAL BUILDING CODES SHOULD BE CONSULTED IN
ALL CASES AS TO THE PARTICULAR REQUIREMENTS
CONCERNING THE INSTALLATION OF FACTORY BUILT
FIREPLACES.
Select the location for the fireplace by taking into
consideration the factors previously outlined in the
Planning Ahead
section of the manual.
Step 1: Framing the Firebox
The width of the framed opening must be 39-1/4” for
ADCH39F or 45-1/4 for ADCH45F (see figure 3).
The entire fireplace can be elevated above the floor to
achieve a raised hearth effect. This can be done by adding
a small platform to achieve the desired height.
Step 2: Install the Firebox
Install the firebox into the framed opening by setting it directly in
front of the opening and sliding it into the proper position.
Step 3: Level the Firebox
Check the level of the firebox on the top edge of the fire-
place face. Shim if necessary.
Step 4: Secure the Firebox
Secure the fireplace to the framing. The nailing flanges on
the firebox will make securing the firebox to the frame quick
and easy. Use appropriate size nails or screws to secure
the firebox.

FIREPLACE CLEARANCES
The fireplace may be placed directly on a combustible floor,
against a combustible wall at marked clearances or on a
raised wooden platform.
If the fireplace is to be installed on a raised wooden platform,
the platform must be a continuous level surface. The fireplace
must be secured in place so it cannot shift positions. The
nailing flanges on the sides of the firebox make securing it to
the framing easy. They were designed to allow the installation
of ½" wallboard or plywood flush with the face of the fireplace.
Only the header (see figure 2) may rest on the standoffs on
top of the firebox.
When the fireplace is installed over carpeting, vinyl, tile or
any combustible material other than wood flooring, it must
be ins talled on a metal or wood panel extending its full
width and depth. Alternatively, the carpeting, vinyl tile, etc.,
may be removed from beneath the fireplace before
installing. COMBUSTIBLE MATERIALS MUST NOT BE
INSTALLED OVER OR TOUCH ANY BLACK PAINTED
SURFACE. DO NOT BLOCK HEAT CIRCULATING AIR
OUTLETS. DOING SO MAY RESULT IN POTENTIAL FIRE
HAZARD.
CLEARANCES
To ensure a safe installation the following instructions must
be carefully observed.
1. Sidewall Clearances:
Clearances from the side of the
fireplace opening to any combustible wall should not be
less than 5", (see figure 6A).
2. Ceiling Clearances:
The ceiling height should not be
less than 42"
from the top of the fireplace opening.
3. Mantel Clearances:
A. If the fireplace has no mantelpiece, then the heat
resistant material must extend upwards a distance of at
least 9 1/2" from the fireplace opening, (see figure 6B).
B. Noncombustible materials used in this installation such as
slate, marble, tile, etc. must be at least 1/2" thick. Do not
install a combustible material behind sheet metal. Failure
to use noncombustible materials above the opening as
specified in these instructions may cause damage to the
materials used and create a fire hazard.
C. A combustible mantle piece may project 1" from the
wall at 9
1
/
2
" above the fireplace opening. A 6" mantle
projection at 16" above the fireplace opening and a 10"
projection at 24" above the opening, (see figure 6B and
6C).
D. An optional heat reducing canopy is available for this
fireplace. Use this canopy to reduce mantel heights as
shown in figure 6D.
?
To install the optional canopy, begin by making sure that
along with the canopy there are also four sheet metal
screws. The canopy has four holes along the top edge.
The middle two holes are smaller than the outer holes.
The canopy will fit tightly in the top front edge of the
fireplace opening with the two larger outer holes clearing
two screws that already exist. Attach the canopy by the
two center holes and the two holes on the ends of the
canopy at the bottom with the four sheet metal screws
provided.
