If additional ventilation to adjoining room
is supplied with grills or openings, add the
volume of these rooms to the total volume
of the space.
2. Multiply the space volume by 20 to deter-

If the actual Btu/Hr used is less than the

AIR FOR COMBUSTION AND VENTILATION
ventilation Air From outdoors
veNtIlAtIoN AIR
Provide extra fresh air by using ventilation
grills or ducts. You must provide two perma-
nent openings: one within 12" of the ceiling
and one within 12" of the floor. Connect these
items directly to the outdoors or spaces open
to the outdoors. These spaces include attics
and crawl spaces. Follow the National Fuel
Gas Code, ANSI Z223.1/NFPA 54, Air for
Combustion and Ventilation for required size
of ventilation grills or ducts.
Ventilation air from inside Building
This fresh air would come from an adjoining
unconfined space. When ventilating to an
adjoining unconfined space, you must provide
two permanent openings: one within 12" of the
ceiling and one within 12" of the floor on the
wall connecting the two spaces (see options
1 and 2, Figure 4). You can also remove door
into adjoining room (see option 3, Figure 3).
Follow the National Fuel Gas Code, ANSI
Z223.1/NFPA 54, Air for Combustion and
Ventilation for required size of ventilation
grills or ducts.
IMPORTANT: Do not provide openings for
inlet or outlet air into attic if attic has a thermo-
stat-controlled power vent. Heated air entering
the attic will activate the power vent.

IMPORTANT: Make sure firebox is level.
If firebox is not level, log set will not work

Note: Your firebox is designed to be used in
zero clearance installations. Wall or framing
material can be placed against any exterior
surface on the rear, sides, top or bottom of
your firebox, except where standoff spacers
are integrally attached. If standoff spacers are
attached to your firebox, these spacers can
be placed directly against wall or framing ma-
terials. Use the dimensions shown for rough
opening to create the easiest installation.

*Minimum 16" from Side Wall
Use dimensions shown for rough openings
to create the easiest installation (see Built-In
Firebox Installation, page 11).
mantel clearances for built-In Installation
If placing custom mantel above built-in firebox,
you must meet the minimum allowable clear-
ance between mantel shelf and top of firebox
opening shown in Figure 6, page 11. These
are the minimum allowable mantel clearances
for a safe installation. Use larger clearances
wherever possible to minimize the heating of
objects and materials placed on the mantel.

installing firebox into a framed-in enclosure.
This makes the front of firebox flush with wall.
Optional brass trim accessories are available
(see Accessories, page 18). The brass trim
will extend past sides of firebox approximately
1/2". This will cover the rough edges of the

rotary squirrel cage type blower with magnetic
attachment and variable speed control. The
BK3 is a triple fan blower system with an on/
off rocker switch.
Locate the recessed knockout in one of the
firebrick sidewall liners (see Figure 9 on page
12 and Figure 10). Firmly tap the center of
the knockout with a chisel until it is released.
Carefully chisel the rough edges of the hole
to smooth edges. This hole will line up with
the hole in the outer casing.
On 32" models only, the blower must be
installed by removing the lower face panel
and placing blower into its proper mounting
position. The 36" and 42" models can use
this method or remove the bottom front re-
fractory brick liner and access panel to allow
installation through the firebox bottom (see
Figure 11).

Decide which way you intend to gain access model bk Installation
into the bottom rear of the firebox to install 1. Attach the power cord to blower motor by
the blower accessory. The lower front panel
can be removed easily by snapping out the
front with a flat blade screwdriver. Use cau-
tion not to scratch any surfaces. Models with
louvered front panels can also be removed by
inserting fingertips between slots and gently
pulling out. DO NOT FORCE. The panels are
actually held in place by means of a retention
dimple embossed on the edge of removable
panels.
firmly pushing two female terminals at end
of power cord onto two spade terminals
on blower motor (see Figure 13).
2. Attach green ground wire from power cord
to blower housing using screw provided
(see Figure 13). Tighten screws securely
with a phillips screwdriver.
3. Place blower against lower rear wall of
firebox outer wrapper with exhaust port di-
rected upward. Depending on your model,
you may have to carefully route the blower
assembly past controls and brackets and
position blower inside back opening. The
blower will be held in position against the
back wall by magnets incorporated onto
blower housing (see Figure 13).
Accessibility to the bottom on 36" and 42"
models only, can also be gained through the
access panel underneath the bottom front
refractory brick liner. Lift the bottom front
refractory brick liner up and out of the firebox
floor, exposing the rectangular shaped access
panel (see Figure 11, page 13). The sides and
back refractory brick liner pieces do not have
to be removed. Lift access panel out by using
finger holes. Blower accessory BK or BK3 can
now be installed.
4. Be certain that all wire terminals are
securely attached to terminals on blower
motor and that the screw retaining the
green ground wire is tight.
5. Position speed control bracket over flange
on hearth pan by sliding it up between
firebox face and hearth pan flange, then
down until seated onto lower flange of lou-
ver opening (see Figure 14, page 15).

approved by FMI PRODUCTS, LLC. Warranty parts must be obtained through authorized dealers of this
product and/or FMI PRODUCTS, LLC who will provide original factory replacement parts. Failure to use
