not waterproof. Water and condensing water vapor may enter the
chase under certain conditions.
Thereboxwillnotperformasanexteriorwall.Moisture
penetration must be considered for construction that places the
reboxinstructurewallsoronmoisturesensitivesurfaces.
When installed next to exterior walls: Empire Comfort Systems
recommendsthereboxchasebeconstructedoutsidethe
structure's weather envelope. Where the platform meets the wall,
useaashingdetailsimilartothatrequiredforattacheddecks.
Chase platforms, including hearths should slope away from the
structureat1/4inchperfoot.Thereboxcanbeshimmedlevel.
When installed on surfaces where water may collect or cause
damage: Empire Comfort Systems recommends a slope of
1/8 inch to 1/4 inch per foot towards the drain port suggested.
Thereboxcanbeshimmedlevel.
Hearthsshouldslopeawayfromthefrontofthereboxand
chase at 1/8 inch to 1/4 inch per foot. Metal safety strips must
be on top of any combustible hearth materials used for moisture
management.
Whenpurchasingareboxwerecommendyoualsobuya
weathercoverorglassdooraccessorytoprotectthereboxfrom
moisture.Neverinstallthereboxwheremoisturecannotdrain

Qualied Installing Agency
Installation and replacement of gas piping, gas utilization
equipmentoraccessoriesandrepairandservicingofequipment
shallbeperformedonlybyaqualiedagency.Theterm"qualied
agency"meansanyindividual,rm,corporationorcompany
which either in person or through a representative is engaged
in and is responsible for (a) the installation or replacement of
gas piping or (b) the connection, installation, repair or servicing
ofequipment,whoisexperiencedinsuchwork,familiarwithall
precautionsrequiredandhascompliedwithalltherequirements
of the authority having jurisdiction.
Whenthereboxisconnectedtoaxedpipingsystem,the
installation must conform with local codes, or in the absence
of local codes with the National Fuel Gas Code, ANSI Z223.1*/

During manufacture and fabricating, components of this
appliance are treated with oils, lms, and/or bonding
agents. These are not harmful, but may produce smoke and
smells as they are burned off during initial operation of the
appliance. This is normal.
Solidfuelsshallnotbeburnedinthisrebox.
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.
When installation application includes highly acidic applications
such as acid wash 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
immediately.
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rebox.
Commonwealth of Massachusetts: The installation must be
madebyalicensedplumberorgastterintheCommonwealth

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.
WARNING: CONNECTION DIRECTLY TO AN
UNREGULATED L.P. SUPPLY CAN CAUSE AN EXPLOSION.
