The fi rebox may be positioned and then the
framing built around it, or the framing may
be constructed and the fi rebox positioned into
the opening.
Usually, no special fl oor support is needed for
the fi rebox, however, to be certain:
1.
Estimate the total weight of the fi rebox
system and surround materials such as
marble, brick, stone, etc., to be installed
(see
Product Referance Table
on
Page 10
for appliance weight).
2.
Measure the square footage of the fl oor
space to be occupied by the system and
surrounds.
3.
Note the fl oor construction, i.e. 2" x 6", 2" x
8" or 2" x 10", single or double joists, type
and thickness of fl oor boards.
4.
Use this information and consult your lo-
cal building code to determine if you need
additional support.
If you plan to raise the fi rebox, build the plat-
form assembly then position fi rebox on top.
Secure the platform to the fl oor to prevent
possible shifting.
Firebox Installation
Step 1.
Frame these appliances as illustrated in
Figures 7 through 9
.
All framing details must
allow for a minimum clearance to combustible
framing members as shown in
Figures 2
through 4
. Also refer to appliance specifi cations
on
Page 10
. Headers may be in direct contact
with the appliance top spacers but must not
be supported by them or notched to fi t around
them. All construction above the appliance
must be self supporting,
DO NOT
USE THE
APPLIANCE FOR STRUCTURAL SUPPORT.
NOTE:
The framed depth from a framed wall,
must always be measured from a fi nished
surface. If a wall covering such as drywall is
to be attached to the rear wall, then the depth
must be measured from the drywall surface.
It is important that this dimension be exact.
Step 2.
Level the fi rebox by checking the top
edge of the fi rebox. Shim if necessary.
Step 3.
Fireplace should be secured to side
framing members using the full length nailing
tabs at the top and bottom of the fi replace front
face. Use 8d nails (
see
Figure 5
).
Firebox Framing
Construct fi rebox framing following
Figures 7
through 9
and
Table 1
on
Page 11
for your
specifi c installation requirements. Refer to
Figure 6
on
Page 10
for fi rebox dimensions.
The fi rebox may be installed directly on a
combustible fl oor or raised on a platform of
an appropriate
height. When the appliance is
installed directly on carpeting, vinyl tile or other
combustible material, other than wood fl ooring,
the appliance shall be installed on a metal or
wood panel extending the full width and depth
of the appliance. Be sure fi rebox rests on a solid
continuous fl oor or platform with appropriate
framing for support and so that no cold air can
enter room from under the fi rebox.
NOTE:
The nailing fl ange and the area directly
behind the nailing fl ange is exempt from the
clearances described on the fi rebox clearance
label.
Step 4.
To safely operate the heater with con-
sideration of the mantel clearances the hood
must be installed (Models VRT2536WS and
VRT2542WS Only).
CAUTION
Do not block the heat-circulating
air inlets and outlets on these
fi reboxes. Doing so may create a
potential fi re hazard.
IMPORTANT
Under no circumstances shall the
fi rebox top spacers be removed or
modifi ed (see
Figure 6)
. The header
may be in direct contact with the top
spacers but must not be supported
by them, notched or altered to fi t
around them.
