TELEVISION CONSIDERATIONS
Installing a television above an rebox has become increasingly
popular;however, the area above anyreboxgetshotandmost
TV manufacturers recommend against placing their products near
a heat source.
If you install a television above this rebox, Empire Comfort
Systems accepts no responsibility for damage or injuries. Follow
the television manufacturer’s installation instructions, including any
recommendations regarding proximity to heat sources.
IfyouhaveaTVaboveyourrebox,turnoffthereboxandletit
cool completely before servicing or touching any buttons on the TV.

44373-0-0522Page 10
Inplanningtheinstallationfortherebox,itisnecessaryto
determine where the unit is to be installed. Gas supply piping
should also be planned at this time.
Thereboxcanbemountedonanyofthesesurfaces:
1. Aatcombustibleornon-combustiblesurface.
2. A raised platform combustible material.
3. Fourcornersofthereboxsocontactismadeonallfour
perimeter edges on its bottom.
(Example: Four concrete blocks - if allowed by local code.)
Ifthereboxisinstalleddirectlyoncarpeting,tileorother
materialotherthanwoodooring,itshouldbeinstalledona
metal or wood panel extending the full width and depth of the
rebox.
Decide what components to include in your installation.
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.
Installthereboxinanareashelteredfromdirectwind,which
maycauseerraticamesandmainburneroutage.Erraticames
could also cause soot on logs, walls or ceiling. Flame outages
and sooting are nuisances but pose no safety issues.
Typical installation may include covered patio, gazebo or an
outside wall of a house.
• Minimum porch area – 96 sq ft
• Minimum ceiling height – 84 inches
Installation in partial enclosures must conform with one of the
following conditions:
• With walls on all sides, but with no overhead cover. See
Figure 4.
FIREPLACE
Figure 4
• Within a partial enclosure which includes an overhead cover
and no more than two side walls. These side walls may be
parallel, as in a breezeway or at right angles to each side.
See Figure 5.
FIREPLACE
Figure 5
• Within a partial enclosure that includes an overhead cover and
three side walls, as long as 30 percent or more of the horizontal
periphery (perimeter of walls and open side) of the enclosure
is permanently open. See Figure 6.
FIREPLACE
Figure 6
If installing in a screened in porch, the open space must be adjusted
(increased) from 30 percent (adjusted open space = 30% / % open
area of the screen mesh). “Example, if you used a screen with a
66% open area, the minimum open space of your building must
be 46% of the periphery. If you have a covered screened-in porch
that has two side walls that are 16’, one wall that was against the
house that’s 20’ and one open side that’s 20’, you would have a
perimeter of 72’. You would need to have 33’ of the perimeter open
(72’ x 46% = 33’).”
(Contact your screen manufacturer or screen dealer to
determine your screens open area).
Outdoor Firebox Enclosure Requirements
Donotinstallreboxuntilallnecessaryprovisionsaremadefor
combustion and ventilation air. Consult the written instructions
providedwiththereboxforinformationconcerningcombustion
and ventilation air. In the absence of instructions, refer to
theNationalFuelGasCode,ANSIZ223.1/NFPA54,Airfor
Combustion and Ventilation, or applicable local codes.

Finishing
All joints (top, bottom and sides), where the wall or decorative
facingmaterialmeetsthereboxsurroundmustbesealedwitha
non-combustible material (300°F + Sealant).
NOTICE: 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 rebox be cleaned with a stainless steel
cleaner immediately.
Cleaning Instructions at Installation
This rebox 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.

GAS LINE CONNECTION
ThereboxisdesignedtoacceptagaslineforanANSIapproved
burner.Havethegas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 hook-up at the
installed burner. The Commonwealth of Massachusetts requires
thataexiblegasconnectorcannotexceedthreefeetinlength.
Gasaccessholesareprovidedonbothsidesoftherebox.See
Figure 12. 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 13.
After the brick panel knockout is removed, the rebox wrap will
havearoundmetalknockoutthatmustberemovedalso.Usea
screwdriver to punch out the metal knockout.
