Attention:Add3-3/4"to"A"Dimensionwhenusingushmantelbase.
Framing dimension A includes a three inch clearance for standoffs on re-
box.
Any vent-free Gas Log Heater must be “For use with approved ANSI
Z21.11.2 unvented room heater.”
Follow and complete the installation instructions of the gas log set
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.
3. Recessedintotheoorasillustratedby Figure 4(ushface),
and Figure 5 (louvered models).
4. Supportedunderall(4)cornersofthereboxsothatcontact
is made on all four perimeter edges on the bottom of the unit
(Example: Four (4) 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

reboxfacingmaterial.Thereboxframingshouldbeconstructed
of 2 x 4 lumber or heavier. The framing headers may rest on the
topofthereboxstandoffs.RefertoFigures 6 and 7forrebox

providedonthereboxtoattachreboxtoframing.Differenthole
locationscan beused fornishing materialswith thicknessesof
3/8", 1/2" and 3/4". Attach these materials with screws provided,
two (2) per framing bracket. See Figure 8.
Framingbracketsshouldtdirectlyagainstframingmaterial.Use
at least one (1) nail per bracket to secure in place.
Checksquarenessofthereboxpriortosecuringtoframedopening.
See Figure 9.
Figure 8
Ablackhoodthatisfurnishedwitheachrebox(oroptionalhood)
MUST be installed before the rebox is used. Failure to do so
may create a possible re hazard. The hood is located behind
upper louver, or inside the rebox on ush face units. If brass,
stainless steel, or hammered pewter hoods are desired, they can
be purchased as an option. Attachment is the same as the standard
black hood.

Thereboxisdesignedtoaccepta3/8-inchgaslineforanapproved
vent-freegaslogset.Havethelineinstalledbyaqualiedservice
person in accordance with all building codes. Consult local building
codes to properly size the gas supply line leading to the 3/8-inch
hook-up at the unit. The state of Massachusetts requires that a
exibleapplianceconnectorcannotexceedthreefeetinlength.
Gasaccessholesareprovidedonbothsidesoftherebox.See
Figure 11. On models with refractory brick panels installed,
carefully remove the knockout in the refractory brick panel using a
large standard screwdriver and hammer. First, place screwdriver in
groove next to plug and pry sideways to pop out main plug. Then
remove the remaining concrete in hole with gentle tapping with ball
peen hammer and/or screwdriver. A masonry drill and bit may also
be used to create a clean hole for the gas line to pass through.
See Figure 12.
When installing optional ceramic ber side panels into rebox,
laypanelonaatsurface.Removethegaslineknockout(round
depression) in the appropriate side panel using a drill or utility knife.
When installing decorative stainless steel or reflective black
liners,gasaccessholesinthebottomofthereboxarerequired.
If no access holes are available in the bottom of the rebox,
see Installation Instructions for decorative liners for proper hole
placement.
Afterthebrickpanelknockoutisremoved,thereboxwrapmay
have a round metal knockout that must be removed also. Use a
screwdriver to punch out the metal knockout.
Check gas type. Use only the gas type indicated on the gas log
set rating plate. If the gas listed on the plate is not your type of gas
supply, DO NOT INSTALL. Contact your dealer for proper model.
AlwaysuseanexternalregulatorforallLPreboxestoreducethe
supply tank pressure to a maximum of 14" w.c. This is in addition
totheregulatorttedtothelogset.
WARNING: CONNECTION DIRECTLY TO AN UNREGULATED
L.P. TANK CAN CAUSE EXPLOSION.
