Vermont Castings • Deant Flexburn 1975 Installation Manual_R1 • 2021 - ___ • 08/21 58390-035i
A. Design and Installation Considerations
Considerationmustbegivento:
 • Safety
 • Convenience
 • Tra󰀩cow
 • Chimneyandchimneyconnectorrequired
Itisagoodideatoplanyourinstallationonpaper,usingexact
measurementsforclearancesandoorprotection,before
actuallybeginningtheinstallation.Ifyouarenotusingan
existingchimney,placetheappliancewheretherewillbea
clearpassageforafactory-builtlistedchimneythroughthe
ceilingandroof.
Werecommendthataqualiedbuildinginspectorandyour
insurancecompanyrepresentativereviewyourplansbefore
andafterinstallation.
Ifthisapplianceisinanareawherechildrenmaybenear
itisrecommendedthat youpurchaseadecorativebarrier
togoinfrontoftheappliance. Remembertoalwayskeep
childrenawaywhileitis operatinganddonotletanyone
operatethisapplianceunlesstheyarefamiliarwiththese
operatinginstructions.
C. Negative Pressure
Negativepressureresultsfromtheimbalanceofairavailable
fortheappliancetooperateproperly.Itcanbestrongestin
lowerlevelsofthehouse.
Causes include:
• Exhaustfans(kitchen,bath,etc.)
• Rangehoods
• Combustionair requirementsfor furnaces,water
appliancesandothercombustionappliances
• Clothesdryers
• Locationofreturn-airventstofurnaceorairconditioning
• ImbalancesoftheHVACairhandlingsystem
• Upperlevelairleakssuchas:
- Recessedlighting
- Attichatch
- Ductleaks
B. Fire Safety
Toprovide reasonable resafety, the followingshouldbe
givenseriousconsideration:
1. Install at least one smoke detector on each oor of
your home to ensure your safety. They should be
located away from the heating appliance and close
to the sleeping areas. Follow the smoke detector
manufacturer’splacementandinstallationinstructions,
andbesuretomaintainregularly.
22 Getting Started
Checkbuildingcodespriortoinstallation.
• InstallationMUSTcomplywithlocal,regional,stateand
nationalcodesandregulations.
• Consultinsurance carrier,localbuilding, reo󰀩cials
or authorities having jurisdiction about restrictions,
installationinspection,andpermits.

b. Notifyredepartment.
Notice: Hearth & Home Technologies assumes no
responsibility for the improper performance of the
appliancesystemcausedby:
• Inadequatedraftduetoenvironmentalconditions
• Downdrafts
• Tightsealingconstructionofthestructure
• Mechanicalexhaustingdevices
• Overdraftingcausedbyexcessivechimneyheights
• Idealperformanceiswithheightofchimneyof16feet
(4.88m)measuredfromthebaseoftheappliance.
Asphyxiation Risk
• Negativepressure cancause spillage
of combustion fumes, soot and carbon

therequirementsofPartJoftheBuildingRegulations2000
(CombustionAppliancesandFuelStorageSystems).This
canbeachievedbyensuringthatthehearthisconstructed
and sized in accordance with the guidelines included in
section2ofapproveddocument‘J’.Thesizeandclearances
ofthehearthareasfollows:
Theconstructedhearthshouldbeconstructedinaccordance
withtherecommendationsindocumentJ,andshouldbeof
minimumwidth840mmandminimumdepth840mm(ifa
freestandinghearthb)above)oraminimumprojectionof
150mmfromthejamb(ifarecessedheartha)above).
Unlessthestovehearthiscompletelynoncombustible,the
bottomheat shieldshould beinstalled toprovide radiant
protection for framing which may be below the hearth.

Do not assume that your replace hearth is completely
noncombustible.
Many fireplace hearths do not meet the “completely
noncombustible”requirementbecausethebrickorconcrete
infrontofthereplaceopeningissupportedbyheavywood
framing.(Figure11)Becauseheatpassesthroughbrickor
concretereadily,itcaneasilypassthroughtothewood.As
aresult,suchreplacehearthscanbearehazardandare
consideredacombustibleoor.
Keep in mind, also, that many raised hearths will extend
lessthantherequiredclearancefromthefrontoftheheater
whenitisinstalled.Insuchcases,su󰀩cientoorprotection
