FIRESTOP SPACERS (FS-10)
Firestop spacers are required at each point
where the chimney penetrates a oor space.
Their purpose is to establish and maintain
the required clearance between the chimney
and the combustible materials. When the pipe
passes through a framed opening into a living
spaceabove,therestopmustbeplacedonto
theceilingfrombelowasshowninFigure12.
They also provide complete separation from
one oor space to another or attic space as

PENETRATING ROOF
Tomaintaina2"clearancetothepipeona
roof with a pitch, a rectangular opening must
be cut.
1. Determinecenterpointthroughwhichpipe
will penetrate roof.
2. Determine center point of roof. Pitch is
distance the roof drops over a given span,
usually 12". A 6/12 pitch means that roof
drops 6" for each 12" measured horizon-
tally down from roof rafters.
3. Useroofopeningchart(Figure14,page

hazardmaybecreated(seeFigure30).
Areplaceequippedwithglassdoorsoperates
muchdifferentlythanareplacewithanopen
front.Areplacewithglassdoorshasalimited
amount of air for combustion.
Excessiveheatwithinthereplacecanresultif
toolargeareisbuiltorifcombustionairgate
isnotcompletelyopen.Thefollowingtipsshould
be followed to assure that both the replace
and glass door retain their beauty and function
properly.Boththeuedamperandglassdoors
mustbefullyopenedbeforestartingre.Thiswill

PUREFIRE EMISSION CONTROL SYSTEM
This replace is equipped with a PureFire
Emission Control System. The Catalytic
Hoodsystemreducesparticulatesemissions
inawoodburningreplacetomeettheEPA
Wood-Burning Fireplace Program Phase 2
emission level.
TheEPAqualifyinglabel,shownonpage18,
willbeafxedtothecatalyst.Beforelighting
therstre,removeandmaintainthislabelin
a safe place if needed for permits or building
inspection.Priortobeginninginstallation,con-
tactyourlocalbuildingofcialtodeterminethe
needtoobtainapermit.Forproperoperation,
catalyst must be replace every 3 to 5 years.
FUELING GUIDELINES
Thereplacegratemustalwaysbesecured
totheretainingbracketsprovided.Theposi-
tion of the grate must be centered against the
backwalloftherebox.
Burn only dry, seasoned (cured) wood with
less than 20% moisture. Avoid the use of
treated, painted and laminated wood. Never
burngarbageorotherforeignmaterials.Do
notusearticiallogs,colorednewspaperor
petroleumbasedrestarters.Avoidwoodwith
high salt content. All of these materials may
contain compounds which can shorten the
life of the catalyst. Wet or unseasoned wood
may lower catalytic temperatures and result
ininefcientoperation.
Thecatalystisdesignedtofunctionatopti-
mumefciencywhenthereplaceisburning
clean, dry, cord wood as replace fuel.A
simple visual inspection of the chimney dur-
ing the wood burning process will determine
catalyst performance.
The fuel load should always be placed on
thebackofthegrate. Usecleandry wood,
seasoned cord wood is the best choice.
Never burn trash, plastics, gasoline, rubber,
industrialsolvents,ammableliquids,naptha,
household garbage, material treated with
petroleum products, leaves, paper products,
cardboard or salt driftwood.
RefertoyourFMIPRODUCTS,LLCHome-
owner's Guide includedwithyourreplacefor
properrebuildingtechniqueandashremoval
procedures.Thesefuelingguidelinesmustbe
followed in order to achieve maximum emis-
sionsperformancefromthePureFireSystem.
OPERATION
Theproperuseofawoodburningreplace
equipped with the catalyst will signicantly
reducetheemissionsthatitproduces.Simple
fuel considerations with regard to moisture
content, size, and quality of fuel will help
control the production of wood smoke and
improve the performance of the catalyst and
replace efciency. With proper care, the
catalyst will provide years of fuel savings
and lowered emissions. By following some
simple guidelines, you will ensure maximum
performance and longevity.
Thesmokethatisusually seencomingout
of a chimney is essentially a combination of
unburned fuel (carbon and hydrogen) and
moistureintheformofwatervapor.Thecata-
lyst is a technology that provides secondary
combustion for the wood burning process.
MAINTENANCE
ThePureFireSystemisamaintenancefree
technology.Donotattempttoremoveorclean
thecombustor.Thedirectamefromthere
will clean the combustor. Only a certified
technicianshouldremovetheunit.Toensure
properreplaceoperation,thePureFireSys-
tem should be replaced every 3 to 5 years
(see Parts on page 20).
NOTE:Chimneysmokemaybevisibleduring
therst8to10minutesofreplaceoperation
whenthereisrstgettingstartedandthe
nal8to10minutesofoperationwhilethere
isdissipating.Undernormaloperatingcondi-
tions, you should see little or no smoke coming
out of the chimney. If continuous smoke is
visible, make sure only dry seasoned wood
isbeingburned.Ifvisiblesmokecontinues,
the combustor has ceased to function or there
isthermalcrumbling.CallFMIPRODUCTS,
