Determinethesafestandmostefcientlocation
foryourDESAdirect-ventreplace.Makesure
thatraftersandwallstudsarenotinthewayofthe
ventingsystem.Choosealocationwheretheheat
outputisnotaffectedbydrafts,airconditioning
ducts, windows or doors. Figure 2 shows some
commonlocations.Beawareofallrestrictionsand
precautionsbeforedecidingtheexactlocationfor
yourreplaceandterminationcap.
When deciding the location of your replace,
followtheserules:
• Donotconnectthisreplaceventingtoachim-
neyueservingaseparatesolid-fuelburning
replaceorappliance.
• Due to high temperatures, do not locate this
replaceinhightrafcareas,windyordrafty
areasornearfurnitureordraperies.
• Properclearancesmustbemaintained.
• Ifyourreplaceistobeinstalleddirectlyon
carpeting,vinyltileoranycombustiblemate-
rialotherthanwood,itmustbeinstalledona
metalorwoodpanelextendingthefullwidth
anddepthofthereplace.SeeFigure3.
• Yourreplaceisdesigned tobeused inzero
clearanceinstallations.Wallorframingmaterial
canbeplaceddirectlyagainstanyexteriorsur-
faceontheback,sidesortopofyourreplace,
except where standoff spacers are integrally
attached.Ifstandoffspacersareattachedtoyour
replace,thesespacerscanbeplaceddirectly
againstwallorframingmaterial.Seeframing
detailsonpage5.
• Ifyouplanoninstallingatelevisionorenter-
tainmentcenterrecessedaboveyourreplace,it
isrecommendedthatyoumaintainaminimum
18"abovetopoflouveropening.
• Whenlocatingterminationcap,itisimportant
toobservetheminimumclearancesshownin
Figure7,page8.
• If recessing into a wall, you can avoid extra
framingbypositioningyourreplaceagainst
analreadyexistingframingmember.
• Do not recess termination cap into a wall or
siding.
• Youmaypainttheterminationcapwith450ºF
heat-resistantpainttocoordinatewiththeex-
teriornish.

iftheterminationcapistobeinstalleddirectly
ona combustible nishsuchasvinyl, wood,

• Ventpipeairspaceclearancestocombustibles
are 1" on all sides except on the horizontal

Figure16onpage11).
• Havereplaceandselectedventcomponentson
