UVSRC Series Fireboxes

Install Fan Kit Assembly
Refer to the Fan Kit (Model FK12) installation instruc-
tions for field installation. (Fig. 8)
WHEN INSTALLED, THE FIREBOX MUST BE
ELCTRICALLY CONNECTED AND GROUNDED (See
Figure 14) IN ACCORDANCE WITH LOCAL CODES,
OR IN THE ABSENCE OF LOCAL CODES:
U.S. INSTALLATIONS — Follow local codes and the
National Electrical Code ANSI/NFPA No. 70.
Cold Climate Insulation
In cold climates, insulation of the enclosure around the
firebox is suggested to avoid problems with cold air.
Insulating the enclosure around the firebox is
recommended, but not a requirement.
The following steps are suggested to minimize cold air
problems.
Insulate the base of the firebox with a noncombustible
insulation. This step is particularly important for outside
wall installations over concrete slab floor construction. If
a platform is used to raise the firebox, the insulation
should be placed on top of the platform before the
firebox is set. (Fig. 9)
Refer to Page 5, Figure 3 for minimum clearances to
combustibles.
Inspect joints of the firebox as well as the points of
sealing between the firebox and the finishing materials.
Any cracks should be sealed with noncombustible
caulking or insulation. Refer to Figures 9 and 10 for
details of sealing between the firebox and finishing
materials.
When a firebox is installed in a chase or on an outside
wall, the enclosure should be insulated like any other
outside wall of the home. Plywood or hardboard may be
placed on the standoffs and insulation placed on this
surface. (Fig. 10) Noncombustible insulation, such as
vermiculite, Pearlite, Zonalite or unfaced fiberglass
insulation, may be used between the exterior of the
firebox and chase drywall up to 1" from the top of the
firebox.
