Authorities having jurisdiction (i.e. building
inspectors, fire marshals, etc.) should be
consulted before installation to determine the
need to obtain a permit.
When installing the Blower Kit, it is necessary
to bring the power source to the fireplace

Kit instructions.
These fireboxes are approved as univer
sal fireboxes and can be paired with any
ANSI Z21.11.2 approved vent-free log set.
The vent-free log manufacturer’s instructions - including their required dimensional clearances for firebox size, - must
be followed.
Refer to the manual that is packed with the
log set for operating instructions.

Installation Instructions
Choosing the Location
for Your Fireplace
Figure 1 shows some of the many ways your fireplace
may be installed. Consider the traffic pattern in your
room and the location of doors and windows. Moving
air from ceiling fans, open doors and hot air grilles may
cause the flames to soot. If a disturbance is found that
effects the flames, it must be eliminated by turning off
the ceiling fan, closing the door or closing or moving
the hot air register. A corner location may be best where
space is limited.
Your fireplace weighs no more than some of your fine
furniture. If the fireplace is located near a load bearing wall, additional supports to the foundation will not
be necessary. HEAVY FACINGS SUCH AS BRICK,
STONE, ETC., MAY REQUIRE ADDITIONAL FOUNDATION SUPPORT.
ALTHOUGH THIS UNIT MAY BE INSTALLED ON
COMBUSTIBLE SURFACES, IT MUST NOT BE IN
STALLED ON CARPET OR VINYL.
Fig. 2 Locating the fireplace.
Gas Line
The gas line must be installed before framing in the fireplace by a licensed gas line installer.
Drafts
Do not locate the fireplace in high traffic areas or areas
exposed to high drafts and winds. Locate the fireplace
away from furniture and draperies.
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.

T224
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 1/2” wallboard or plywood flush with the face of the fireplace.
Only the header (Fig. 1) 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 installed 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”. (Fig. 3a)
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 9¹⁄₂" from the fireplace opening.
(Fig. 3b)
B. Noncombustible materials used in this installa
tion 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 mantel piece may project 1" from
the wall at 9¹⁄₂" above the fireplace opening. A
6" mantel projection at 16" above the fireplace
opening and a 10" projection at 24" above the
opening. (Figs. 3b and 3c)
D. A heat reducing canopy is shipped with the fire
place. Use this canopy to reduce mantel heights
as shown in Figure 3d.
To install the optional canopy, remove the four
(4) screws supplied with a Phillips screwdriver.
Two (2) screws are located across the top of the
