B. Design and Installation Considerations
NOTICE: Check building codes prior to installation.
• InstallationMUSTcomplywithlocal,regional,stateand
national codes and regulations.
• Consultinsurancecarrier,localbuildinginspector,re
o󰀩cialsorauthoritieshavingjurisdictionoverrestrictions,
installation inspection and permits.
• Before installing,determinethefollowing:
- Wherethereplaceistobeinstalled.
- Theventsystemcongurationtobeused.
- Gas supply piping.
- Electrical wiring.
- Framingandnishingdetails.
- Whetheroptionalaccessories-devicessuchasa
fan, wall switch or remote control - are desired.
1. Selecting Fireplace Locations
Thisreplacemaybeusedasaroomdivider,installed
alongawall,acrossacornerorusedinanexteriorchase.
See Figure 2.2.
Locatingthereplaceinabasementshouldbeavoided.
Locatingnearfrequentlyopeneddoors,centralheat
outletsorreturns,orotherlocationsofconsiderableair
movementcana󰀨ecttheperformance.
Considerationshouldbegiventothesefactorsbefore
deciding on a location.
NOTICE:
A minimum 1-1/2 in. air clearance at the back and
a minimum 1-1/2 in. air clearance to the sides of the
replaceassemblymustbemaintained.
Chimney sections at any level require a 2 in.
minimum air space clearance between the framing
and chimney sections.

• Thechaseisconstructedusingframingmaterialsmuch
thesameasthewallsinyourhome.Avarietyofsiding
materials may be used including brick, stone, veneer
brick,orstandardsidingmaterials.
• In constructing the chase, several factors must be
considered:
- Maintain a 2 in. (51 mm) air space around the
chimney.
- The chase top must be constructed of non-
combustiblematerial.
- Incoldclimates,arestopspacerandatticinsulation
shieldshouldbeinstalledinaninsulatedfalseceiling
at the 8 ft. (2438 mm) level above the replace
assembly.Thisreducesheatlossthroughthechase.
- In cold climates, the walls of the chase should be
insulatedtothelevelofthefalseceilingasshownin
Figure3.3.Thiswillhelpreduceheatlossfromthe
homearoundthereplace.
WARNING! You must install false ceilings and ceil-
ing restops at each oor of the chase or every 10 ft
(3.05 m) to control spread of re.
WARNING! Risk of Fire! DO NOT sealareabetweenre
stop opening and chimney pipe except where they enter
the attic or leave the warm air envelope of the home (use
600° F sealant).
WARNING! Risk of Fire! You must maintain a minimum
2 in. (51 mm) air space clearance to insulation and oth-
er materials surrounding the chimney system.
• Insulationandothermaterialsmustbermlysecuredto
prevent accidental contact with chimney system.
• The chase must be properly blocked to prevent blown
insulation or other combustibles from entering and
makingcontactwithreplaceorchimney.
• Failure to prevent contact between insulation or other
materials and chimney system may cause overheating
andre.

attic insulation shield.
• Failure to keep insulation and other materials away from
chimneypipecouldcausere.
• DO NOTosetchimneyinsideinsulationshield.
• Combustible material may come into contact with the attic
insulation shield as long as the required clearances are
maintained to the chimney pipe.
Double-check the Chimney Assembly
Continueassemblingthechimneysectionsupthrough
the ceiling restops as needed. While doing so, be
aware of the height and unsupported chimney length
limitationsgivenunderSection5.

E. Firebrick Installation
• Theinteriorofthereplacemustbenishedwitheither
refractorypanelsorrebrickinstalledwithmortar.
• Use an indoor/outdoor medium duty refractory mortar
meetingASTMC199.FirebrickmustmeetASTMC27
andC1261.Alsorebrickinstallationshouldcomplywith
local and/or regional codes.
• It is highly recommended that rebrick be laid up by
someonewithmasonryexperience.Itisrecommended
tointerlacerebricksinthejointbetweenthebackand
side walls. Use minimum 1/8” grout spacing. Some
rebrickswillneedtobecut-to-sizeforpropert-up.
• Mortarmaybeusedtolltheleadingedgesoftheside
wallstothenon-combustiblereplacefacingmaterial.
• Startinstallingrebrickatthefrontedgeoftherebox
oorandworktowardtheback.Leave1/2”expansion
gapsfromrebricktothereboxsidesandback.These
gapswillallowroomforrebricktoexpandduringuse
andshouldnotbelledwithmortar.Theseexpansion
gapswillbehiddenbybackandsiderebrick.
• Installrebrickagainstthebackwalloftherebox.Leave
1/2”expansiongapstothereboxsides.
• Install rebrickagainst bothside walls of the rebox.
Startinstallingrebrickfromthefrontoftherebox.
• Itisnotunusualforinstalledrebricktodevelopheat
stresscracksintherebrickormortar.
• If installing an approved front or door, please double
check the dimensions needed in the installation
instructionstoensurethefrontordoorwilltafterthe
