Installation
Planning
Installing Outside Air Kit
In planning the installation for the firebox it is neces-
sary to determine where the unit is to be installed and
whether optional accessories are desired. Gas supply
piping should also be planned.
An outside air kit may be installed in all UVSTR/CVR
Series fireboxes. If desired, or if local codes man-
date the use of an air kit, then an AKU2 is required to
complete the installation (from air kit to out-of-doors).
If the outside air kit is to be used, the AKU2 MUST be
installed BEFORE the fireplace is enclosed. Refer to
the AKU2 instructions for field installation.
These models may NOT be installed in a bedroom
or bathroom.
Glass doors are NOT available for these fireboxes.
The firebox can be mounted on any of the following
surfaces:
•
•
A flat hard combustible surface.
A raised platform of combustible or noncombustible
material.
Nail Top
Standoffs
•
A concrete block or other solid object placed be-
neath each of the four corners of the appliance.
Nail Eight
Side-Nailing
Flanges
If the firebox is installed directly on carpeting, tile or
other combustible material other than wood flooring, it
should be installed on a metal or wood panel extending
the full width and depth of the unit.
At this point, you should have decided what compo-
nents to include in your installation, and where the
firebox is to be located. If this has not been done, stop
and consult your dealer for planning assistance.
UVSTR36
Framing
Firebox framing can be built before or after the firebox
is set in place. Framing should be positioned to ac-
commodate wall covering and firebox facing material.
The firebox framing should be constructed of 2 x 4 or
heavier lumber. The framing headers may rest on the
top of the firebox standoffs Refer to Figs. 1 and 2 for
firebox framing dimensions.

Standoffs

Flanges
Anchor Firebox in Position
To prevent shifting of the firebox and to maintain sealing
(described later), anchor the firebox. Two methods are
possible for these fireboxes.
UVCVR36
One method is to use the eight fastening tabs (four
with cove model) provided with the firebox. (Fig. 5) The
firebox may be secured to the vertical framing members
with these tabs and nails or other suitable fasteners.
FP680
Fig. 5 Adjustable drywall strip (nailing flange).
The second method uses the standoffs at the front of
the firebox. A nail may be installed through the standoffs
and into the header to stabilize the top of the firebox.

UVSTR / UVCVR Series Vent-Free Fireboxes
NOTE: The gas line connection to the log set can be
made with properly tinned 3/8" copper tubing, 1/2" rigid
pipe, or an approved flex connector. Because some mu-
nicipalities have additional local codes, it is always best
to consult your local authority.
Connect the Gas Line
Gas access holes are provided on both sides of the
firebox.
Check gas valve type. Use only the gas type indicated
on the gas log rating plate. If the gas listed on the plate
is not your type of gas supply, DO NOT INSTALL. Con-
tact your Dealer for the proper model.
U.S. INSTALLATIONS – Follow local codes and the
National Fuel Gas Code ANSI Z223.1/NFPA 54.
Always check for gas leaks with a mild
soap and water solution. Do not use an
open flame for leak testing.
Always use an external regulator for all LP fireboxes to
reduce the supply tank pressure to a maximum 14" w.c.
This is in addition to the regulator fitted to the vent-free
heater.
When using copper or flex connector use only approved
fittings. Always provide a union so that gas line can
be easily disconnected for burner or fan servicing. See
gas specification for pressure details and ratings.
WARNING: Connection directly to an un-
regulated LP tank can cause an explosion.
For final connection of the gas log heater to the gas
line, see Section 5 and Figure 6.
Cold Climate Insulation
In cold climates, insulation of the enclosure around the
firebox is suggested to avoid problems with cold air.
1/2" Gas Supply
1/2" x 3/8" Shut-Off Valve
Insulating the enclosure around the firebox is recom-
mended, but not a requirement
3/8" Nipple
3/8" Union
The following steps are suggested to minimize cold air
problems.
3/8"
Insulate the base of the firebox with a noncombustible
insulation. This step is particularly important for outside
wall installations over concrete slab floor construction.
If a platform is used to raise the firebox, the insulation
should be placed onto the platform before the firebox is
set. (Fig. 7)
Nipple
Gas Supply Line
FP598
Fig. 6 Typical gas supply installation.
Refer to Page 5, Figure 3 for minimum clearances to
combustibles.
Install Gas Log Heater
Inspect joints of the firebox as well as the points of seal-
ing between the firebox and the finishing materials.
1. Connect the shutoff valve, union and any required
approved fittings (See NOTE below) between the valve
and the gas line.
When a firebox is installed in a chase or on an outside
wall, the enclosure should be insulated like any other
outside wall of the home. Plywood or hardboard may
be placed on the standoffs and insulation placed on this
surface. (Fig. 8)
Access to the gas line on the UV Series firebox is made
through the left or right side of the firebox. Locate the
appropriate gas line in the outer casing of the firebox
and remove the insulation from the gas line tube.
From the inside of the firebox, locate the knockout on
the firebrick - be sure you are on the appropriate or gas
line side of the firebox. Using a flat- bladed screwdriver
or small chisel and hammer, carefully tap around the
knockout until it loosens and falls out.
2. Install the Vent-Free Gas Log Heater exactly as
described in the instructions for the heater. If for any
reason, you do not have these instructions, contact
your dealer or manufacturer for another copy.

in Figure 3. Failure to do so may create a fire hazard.
Use Top Slot
WARNING: When the black surround is covered
by a brick surface, (Fig. 13), use an extended hood.
The hood should extend out to the brick surface
(Refer to Figs. 13 and 14) and be attached to the
firebox. The maximum brick to noncombustible sur-
face that may extend out past the black surround
surface is 4¹⁄₄".
