Step 4. Noncombustible material (minimum
requirements) with wood mantel or other com-
bustible projections: To install the firebox with
a wood mantel, shelf or other combustible
projection above firebox opening, at least 9" of
noncombustible material must be installed
above the fireboxes described in this manual
(
Figure 4 ).
Example: The bottom of the mantel may project
from the wall a maximum of 2
¹⁄₂
" at a minimum
of 9" above the opening. The top shelf of the
mantel may project a maximum of 6" at a
minimum of 14
¹⁄₂
" above the opening.

Note: The following steps represent the normal
sequence of installation. Each installation is
unique, however, and might require a different
sequence.
Step 1. Position firebox prior to framing or into
prepared framing.
Step 2. Field wire main power supply to circu-
lating models for fan kit. (Electrical connections
should only be performed by an experienced,
licensed/certified tradesman.)
Step 3. Plumb gas line. (Gas connections should
only be performed by an experienced, licensed/
certified tradesman.)
Step 4. Install unvented gas log room heater
per the instructions provided with the unvented
room heater.
Step 5. Complete finish wall material, surround
and optional hearth extension to your individual
taste.
INSTALLATION
Gas Line Installation
CAUTION: PLUMBING CONNECTIONS SHOULD
ONLY BE PERFORMED BY A QUALIFIED, LI-
CENSED PLUMBER. MAIN GAS SUPPLY MUST
BE OFF WHEN PLUMBING GAS LINE TO FIRE-
PLACE OR PERFORMING SERVICE.
Consult all local codes.
It is recommended that the
¹⁄₂
" gas line enter
the right side of the firebox. Connect the gas
line before the firebox is enclosed in the fin-
ished wall. The gas knockout is determined by
a 1
¹⁄₈
" round indentation located at the bottom
and slightly off center in the side refractories.
THE KNOCK-OUT IS ALWAYS REMOVED
FROM INSIDE THE FIREBOX. If removal is
attempted from the outer wrapper, side-re-
fractory damage may occur. With a medium-
sized hammer, lightly tap the surface of the
indentation. The refractory material is very
thin in this area and is easily removed. Once a
small hole has been made, continue tapping
until you have reached sufficient diameter for
the gas line to fit through. The entire knockout
does not have to be removed.
Remove insula-
tion in the gas line channel.
Install only a
¹⁄₂
" (1
¹⁄₂
" max.) inside diameter
approved gas line through the firebox wall for
connection to the unvented room heater inside
the firebox.
If your mantel profile is unsafe, you may either:
• Raise the mantel to an acceptable height, or
• Remove the mantel.
Step 5. Floor clearance: This firebox must be
installed at least 5" above any combustible
flooring material, such as carpeting or asphalt
tile, which is closer than 14" to the base of the
firebox (
Figure 5 ).
Figure 5
The firebox may also be installed nearer to the
floor if a minimum of 14" of noncombustible
material such as slate or marble is installed
between the base of the firebox and the com-
bustible flooring (
Figure 6 ).

ASSEMBLY STEPS
Note: Illustrations shown in this manual reflect
“typical” installations with nominal dimensions
and are for design and framing reference only.
Actual installations may vary due to individual
design preferences. However, always maintain
minimum clearances to combustible materials
and do not violate any specific installation re-
quirements. Refer to the Framing Specifica-
tions Figures on page 7.
The UVFCE system consist of three basic
