andtherequirementsofthisrebox.
Checkallttingsforleaksbeforelightingthegaslogset.
Inplanningtheinstallationfortherebox,itisnecessarytodetermine
wheretheunitistobeinstalledandwhetheroptionalaccessories
aredesired.Gassupplypipingshouldalsobeplannedatthistime.
A gas shut-off must be in this line.
Thereboxcanbemountedonanyofthesesurfaces:
1. Aathardcombustibleornon-combustiblesurface.
2. Araisedplatformofcombustibleornon-combustiblematerial.

andFigure 5(louveredmodels).
4. Supportedunderallfourcornersofthereboxsothatcontact
ismadeonallfourperimeteredgesonthebottomoftheunit
(Example:Fourconcretemasonryblocks).
Ifthereboxisinstalleddirectlyoncarpeting,tileorothercombustible
materialotherthanwoodooring,itshouldbeinstalledonametal
orwoodpanelextendingthefullwidthanddepthoftheunit.
Atthispoint,youshouldhavedecidedwhatcomponentstoinclude
inyourinstallation,andwherethereboxistobelocated.Ifthis
hasnot beendone, stop andconsult your dealerfor assistance
with this planning.
Planning Your Installation
PleasenotethattheoptionalVFA2FreshAirkitavailableforuse
withtheVentFreeFireboxmustbeinstalledatthetimeoftheinitial
installation.Refertopages10,11and12fordetailedinstructions
fortheairkit.
