Cleaning Instructions
This appliance is built using mostly high-grade stainless steel to
resist rust-through. In outdoor applications, all stainless steel will
develop a dull patina and, depending on the local environment
and on the materials used in the installation, may develop some
surface oxidation (rust). This does not affect the performance
of the rebox, and does not require any action to correct. If you
prefer keeping your rebox front looking factory-fresh, clean it as
required with stainless steel cleaner.
When installation application includes highly acidic applications
such as mortar or stone etching, do not remove the protective
PVC lm from the stainless steel until after this application is
complete. Once the lm has been removed we recommend that
the appliance be cleaned with a stainless steel cleaner immedi-
ately.
Please note that areas where the lm has been formed (corners,
hems, etc.) may require extra cleaning due to the properties of
the lm. Ensure that all protective lm has been removed from
the rebox prior to burning the appliance.

In planning the installation for the rebox, it is necessary to determine
where the unit is to be installed and whether optional accessories
are desired. Gas supply piping should also be planned at this time.
The rebox can be mounted on any of these surfaces:
1. A at non-combustible surface.
2. A raised platform non-combustible material.
3. Four (4) corners of the rebox so contact is made on all four
perimeter edges on the bottom of the unit.
(Example: Four (4) concrete masonry blocks.)
If the rebox is installed directly on carpeting, tile or other combustible
material other than wood ooring, 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 components to include
in your installation, and where the rebox is to be located. If this
has not been done, stop and consult your dealer for assistance
with this planning.
This rebox is intended for installation on an outdoor patio or
in your yard. This rebox shall be used only outdoors in a well
ventilated space and shall NOT be used in a building, garage, or
other enclosed area.
It is recommended that this rebox be installed in a “sheltered” area.
Direct wind will cause an erratic ame and possible pilot or main
burner outage. This erratic ame could also lead to excessive black
soot. These issues are nuisance issues rather than a safety issues.
Typical installation may include covered patio, screened porch,
gazebo or an outside wall of a house.
• Minimum porch area – 96 square feet
• Minimum ceiling height – 82 inches
Minimum of two walls to be open or screened to the following
guidelines.
• Minimum screen area – 64 square feet
• Minimum top of screen height (side walls) – 70 inches
Installing the Hood
A stainless steel hood is furnished with each outdoor rebox. The
hood MUST be installed before the rebox is used. Failure to do
so may create a possible re hazard.
Finishing
Hearth extensions are recommended, not a requirement for these
gas reboxs.

The rebox is designed to accept a 3/8-inch gas line for an approved
ventless gas logset. Have the line installed by a qualied service
person in accordance with all building codes. Consult local building
codes to properly size the gas supply line leading to the 3/8-inch
hook-up at the unit. The state of Massachusetts requires that a
exible appliance connector cannot exceed three feet in length.
Gas access holes are provided on both sides of the rebox. See
Figure 8. Carefully remove the knockout in the refractory brick
panel using a large standard screwdriver and hammer. First, place
screwdriver in groove next to plug and pry sideways to pop out
main plug. Then remove the remaining concrete in hole with gentle
tapping with ball peen hammer and/or screwdriver. A masonry drill
and bit may also be used to create a clean hole for the gas line to
pass through. See Figure 9.
After the brick panel knockout is removed, the rebox wrap may
have a round metal knockout that must be removed also. Use a
screwdriver to punch out the metal knockout.
Check gas type. Use only the gas type indicated on the gas log
set rating plate. If the gas listed on the plate is not your type of gas
supply, DO NOT INSTALL. Contact your dealer for proper model.
Always use an external regulator for all LP reboxes to reduce the
supply tank pressure to a maximum of 14" w.c. This is in addition
to the regulator tted to the log set.
WARNING: CONNECTION DIRECTLY TO AN UNREGULATED
L.P. TANK CAN CAUSE EXPLOSION.
Install only a ANSI Z21.97.1/CSA 2.41 ventless log set into this
rebox.
