Firebox must be wired to the house electrical system in
order for the blowers to operate. This blower system does not require
a wall switch. Refer to the VCBK3 blower assembly installation
instructions for details.
Electrical connections are made through the cover on the right side
of the firebox as illustrated in Figure 21. Use 14 AWG copper wire
for all connections. Be certain the firebox is properly grounded to the
green wire.

FINISHING YOUR FIREBOX
Combustible materials may make direct contact with the sides and
the top of the firebox face. It is important that combustible materials
do not overlap the face itself. Brick, tile or other noncombustible
materials may be applied to the face provided that any gap between
the material around the firebox opening is caulked to prevent the
seepage of combustible products.
CAUTION: DO NOT COVER UP THE TOP OR BOTTOM
FACE LOUVERS.

MANTEL
A mantel may be installed if desired (see Figure 22) for minimum
heights above and beyond opening of firebox face.
Woodwork, such as wood trim and mantels, and other combustible
material, shall not be placed within 6 inches of a firebox opening.
Combustible material above and projecting more than 1

/
2
inches
from a firebox opening shall not be placed less than 12 inches from
the top of the firebox opening. NFPA Standard 211 sections 7-3.3.3.
DAMPER OPERATION
The flue gas damper is located inside the firebox similar to a
conventional masonry fireplace. Look within the top of the firebox
and locate the damper handle extending from the damper (see Figure
23) for operating the damper. This can be easily accomplished with
a firebox poker.
FIRE:
Use seasoned hardwood or when using vent-free or
decorative gas appliance use natural or propane/LP gas.
