SMOKE WHEN THE DOOR IS OPENED.
SECTION I
INTRODUCTION
Your Buck Stove is a non-catalytic unit designed to meet the most
stringent emissions standards without the use of a catalytic combustor. This effect is
achieved through the use of a secondary air which is mixed with primary air in
the unit's firebox. For peak performance we suggest the use of hard seasoned wood.
DO NOT BURN GARBAGE OR FLAMMABLE FLUIDS.
The primary air, which is controlled by the user, burns the wood. Secondary air is admitted into
the firebox through the secondary air tubes at the top of the firebox. This secon-
dary air burns the impurities in the smoke released from the initial wood burning. The
temperature necessary for this combustion is maintained through the firebrick refractory. If
any more technical information is necessary contact your local dealer.
This heater is equipped with a standard room air blower. For operation and uses of these
electrical assemblies, see instructions provided in this manual on page 35.

SECTION II
MASONRY INSERT INSTALLATION
The Model 18 may be installed using an all masonry fireplace built in accordance with the
Uniform Building Code and National Fire Protection Association (NFPA). The first step in
this type of installation is to determine the acceptability of the fireplace and chimney for use
with a woodstove. Both the construction and condition of the fireplace are important consid-
erations when installing a woodstove. NOTE: It is not necessary to direct connect this
unit unless installed in improper drawing fireplace or oversized flue. The chimney
should extend at least 3' above the roof and at least 2' above any point of the roof
within 10'.
CAUTION
REMEMBER TO HAVE YOUR CHIMNEY INSPECTED FOR LEAKS AND BLOCKAGE
BEFORE YOU INSTALL YOUR STOVE.
MINIMUM CLEARANCES
A. Unit to adjust to Side Wall
B. Front Floor Protector
C. Side Floor Protector
D. Side Wood Trim
E. Top Wood Trim
F. Mantel or Brackets

1. The hearth must be of masonry construction and must extend a minimum of 16" in front of
the firebox opening and a minimum of 8" to either side of the firebox opening.
2. If there is not minimum hearth protection from the front of the firebox opening and the
front of the masonry hearth, a floor protector must be used in front of the hearth to
protect combustible materials. The floor protector must be 3/8" minimum thickness non-
combustible material or equivalent.
With the floor protector or hearth extension material specified as one layer of 2" thick brick
with a K* factor of 5.0, you may use alternate materials as long as the K factor(s) is calculated
as follows:
FORMULA: Required thickness = (K of alternate material/K of millboard) x (thickness
of millboard)
EXAMPLE: An alternate inorganic non-combustible millboard with a K of .9375
would require a thickness as follows:
Required thickness = (.9375/5.0) x 2 in.
= 3/8 inch
K FACTORS OF ALTERNATE MATERIALS
Material K Required Thickness
Ceroform 126 .21 1/8"
Limestone 8.0 3.2"
Concrete 8.0 3.2"
Sandstone 13.0 5.2"
Marble 18.0 7.2"
A hearth extension or floor protector thickness above four (4) inches is generally not acceptable
due to cost, floor load capacity, and look. The alternate we recommend is using Ceroform No.
126 millboard 1/8" minimum and putting any type decorative brick or stone (any thickness) on
top of it.
*The “K” factor represents the thermal conductivity of a material and is the time rate of heat
flow through a homogeneous material under steady-state conditions, through unit area, per unit
temperature gradient in the direction perpendicular to a surface.

POSSIBLE TOOLS NEEDED FOR INSTALLATION
If you decide to install your own stove, there are several hand tools you may need to do the
job. If you do not already have them, they are readily available at most hardware stores.
Caulking gun
Large adjustable wrench (may not be needed)
Drop Cloths
Vacuum cleaner or whisk broom
Flashlight
1 tube of RTV silicone, Code 103 or 106, or high temperature rubber cement rated between
450° F - 600º F
7/32" drill bit and drill
Socket/Ratchet Set
Insulation (provided in trim kit package)
INSTALLATION PREPARATION
FIREPLACE
1. Locate furniture and other materials away from the front of the fireplace to allow free
access to the fireplace.
2. Cover the hearth and adjacent floor areas with the drop cloth to protect from soiling or
marring the surface.
3. Remove the existing fireplace damper plate.
4. Thoroughly clean the fireplace of ashes and soot.
5. If the fireplace has an ash dump or outside air provision, these must be sealed off with
metal or tightly packed non-combustible insulation to prevent this cold air from entering
the fireplace chamber.
CAUTION
CHECK THE CHIMNEY AND SMOKE CHAMBER FOR EXCESSIVE BUILDUP OF
CREOSOTE OR SOOT. ALSO CHECK FOR OBSTRUCTIONS, SUCH AS BIRD'S
NESTS. IF THE CHIMNEY IS EXCESSIVELY DIRTY, CLEAN IT, OR HAVE
SOMEONE CLEAN IT PROFESSIONALLY BEFORE INSTALLING OR USING THE
ROOM HEATER.
7

INSTALLATION PROCEDURE (Without Direct or Positive Connect Kit)
POSITIONING THE HEATER
When positioning the heater, the following
conditions MUST be met! (See Figure 2.)
1. The front of the damper opening must be
positioned BEHIND the rear edge of the lintel
to ensure proper draft. (See Figure 2.)
2. The vertical plane of the fireplace front must
fall BEHIND the side cold air vent on top of
the unit. (In other words, it is possible to have
the heater too far in as well as not far enough.)
3. Center the heater in the fireplace opening.
MOUNTING THE TRIM PANELS
After the unit is positioned, as shown in Figure 2,
mark the mounting position of the trim panels as
follows:
1. Set the top (long) trim panel in place on top of
the unit. The panel should be flat against the
outside face of the fireplace, and standing
vertically. Mark along the lower edge of the
trim panel with a pencil to make a reference
line for mounting.
2. Set the side trim panels in place behind and
against the intake covers, again, flat against the
face of the fireplace. Mark down the edge of
the trim panel to make a vertical reference line.
3. Slide the unit out of the fireplace far enough to work behind the trim panel reference lines.
4. Mount the side trim panels. (See Figure 3.)
a. Position the trim panel on the reference line.
b. Drill mounting holes in center of trim panels mounting brackets to allow for adjustment in and out if
necessary.
c. Mount the trim panel using the self-tapping screws provided.
5. Place top panel back on reference mark. Mount top trim panel by drilling mounting holes in center of trim
panel mounting brackets, with top end side of top panel overlapping side panel.
6. Using insulation provided, peel and stick to back of panels overlapping fireplace dimensions by 1" on each
side and top. (See Figure 3.)
FIGURE 2
FIGURE 3

7. Next using high heat silicone or furnace cement, run heavy bead of caulking around where panels meet the
stove. (See Figure 4.)
8. Using the brass trim provided with kit, place side brass trim (with straight edge down) over each outer edge
of side trim panel. Next place top brass trim over top trim panel. All 45º corners should match. If not, trim
to fit with a metal cutting blade.
9. Slide the unit back into the fireplace. Check to be sure that the trim panels (and brass) are properly positioned
and lie flat against the front of the fireplace. If panels are out of position, slide the unit out and reset by
loosening the mounting screws and repositioning in the slot. With bar, lift stove in front. Place insulation
across front and the surface of hearth or bottom of fireplace to make complete seal.
10. To check seal of panels, use candle flame and go around the entire area sealed by silicone and insulation. If
flame leans toward inside of fireplace, add additional insulation. This ensures an airtight seal.
WHEN USING DIRECT OR POSITIVE CONNECT KIT FOLLOW STEPS 1-4c.
5. Place top panel back on reference mark. Take top trim panel mounting bracket supplied with unit and position
bracket so it overlaps rear lip of top trim panel. Drill mounting holes in top of stove using holes in bracket as
guide. Tighten down screws.
6. Now, follow the installation procedures in the listed direct connect or positive connect kit you are using and
install the heater and connect kit in the fireplace.
7. Using the brass trim provided with kit, place side brass trim (with straight edge down) over each outer edge
of side trim panel. Next place top brass trim over top trim panel. All 45º corners should match. If not, trim
to fit with a metal cutting blade.
8. Slide the unit back into the fireplace. Check to be sure that the trim panels are properly positioned and lie flat
against the front of the fireplace. If one or more of the panels is out of position, slide the unit out and reset by
loosening the mounting screws and repositioning in the slot.
NOTE: If side and top panels gap due to unevenness of fireplace (normally on rock faced fireplaces) you will
need to drill a 5/32" hole through both side and top panels near where the panels intersect and install a #10 self-
threading screw to eliminate the gap. Paint screws to match.

FINAL CHECK
1. Recheck the specified clearances.
2. Remove all foreign material from the firebox area.
3. Open the primary air draft.
NOTE: Plug the power cord into a 115 VAC outlet. Route the cord to prevent damage to the
cord insulation from heat and sharp objects. Keep the cord out of the way of traffic to prevent
damage caused by tripping, etc.
4. Place crumpled pieces of newspaper in the stove. Light it and close the doors. Ensure
that the stove draws properly through the primary draft.
NOTE: “Do not use grate or elevate fire. Build wood fire directly on hearth.”
5. Check for smoke leaks around the doors.
6. Open the doors and check for smoke escaping from the front of
the stove. Smoking usually indicates a defective or poorly positioned chimney. Some
chimneys with a marginal draft can be preheated by lighting newspaper and holding
it near the open damper with a poker or fire tong. Once the chimney heats up, a proper
draft can usually be obtained.
If a thorough review of the Troubleshooting Guide in the rear of the manual does not reveal
the problem, contact your dealer for assistance.
NOTE: The unit is painted with a specially formulated high temperature paint that cures
during the first two or three firings. You may notice a slight smoking effect and an odor
of burning paint when you build the first fires. This is normal and is not a cause for
alarm. In some cases, these fumes will activate a smoke alarm. Opening a window near
the unit will allow these fumes to escape. Do not build a large, roaring fire until this
curing is complete or the heater finish may be damaged.
The connector and/or chimney should be inspected at least once a month during the heating
season to determine if a creosote buildup has occurred.
CAUTION
NEVER USE GASOLINE, GASOLINE-TYPE LANTERN FUEL, KEROSENE,
CHARCOAL LIGHTER FLUID OR SIMILAR LIQUIDS TO START OR “FRESHEN
UP” A FIRE IN THE HEATER. KEEP ALL SUCH LIQUIDS WELL AWAY FROM
THE STOVE WHEN IT IS IN USE. ALL FLUIDS OF THIS TYPE GIVE OFF
VOLATILE FUMES AND CAN AND WILL EXPLODE!! DON'T TAKE A CHANCE
WITH THE SAFETY OF YOUR HOME AND FAMILY.

SECTION III
PRE-FAB
ZERO CLEARANCE INSERT INSTALLATION
The Model 18 may be installed into any UL listed prefabricated fireplace that is large enough to
accept it.
MINIMUM CLEARANCES
Except for “NOTE(S)”, FOLLOW MASONRY INSTALLATION CLEARANCES FOUND
IN YOUR OPERATIONS MANUAL.
INSTALLATION PREPARATION
Pre-Fab Zero Clearance Fireplace
1. Locate furniture and other materials away from the front of the fireplace to allow free access
to the fireplace.
2. Cover the hearth and adjacent floor areas with drop cloths to protect from soiling or marring
the surface.
3. Remove the existing fireplace damper plate/damper rod assembly.
4. Thoroughly clean the fireplace of ashes and soot.
5. Check the chimney and smoke chamber for excessive buildup of creosote or soot. Also,
check for obstructions, such as bird’s nests. If the chimney is excessively dirty, clean it, or
have someone clean it professionally BEFORE installing or using the room heater.
6. The Ash Lip, Smoke Baffle and Smoke Shelf may also be removed, if necessary, to provide
room for the Model 18. Any other alteration to the unit will void ALL NBC manufacturer’s
responsibility and liability. The WARNING label below must be attached to the back of
the fireplace.
NOTE: Plug the power cord into a 115 VAC outlet. Route the cord to prevent damage to the
cord insulation from heat and sharp objects. Keep the cord out of the way of traffic to prevent
damage caused by tripping, etc.

NOTE: DO NOT BLOCK ANY EXISTING LOUVERS OR VENT ON THE EXISTING
PREFAB WITH ANY TRIM PANELS FOR THE MODEL 18.
NOTE: If the Pre-Fab Zero Clearance Fireplace is not equipped
With HT-2100 degree UL Listed pipe, a UL-1777 Liner must be
Installed the the Full Length of the chimney, and attached to the
Flue Exit of the Insert.
NOTE: If the Pre-Fab Zero Clearance Fireplace is equipped with
HT-2100 degree UL Listed pipe, one of the two following methods
must be met:
HEATER INSTALLATION
1. There are two listed and tested methods of installation of the Model 18 heater into a zero-
clearance or pre-fab fireplace.
A. 6" Increaser
1. The preferred method is to use an increaser made of 24 gauge (minimum) stainless
steel to go from 6" inside diameter to exact diameter of the fireplace throat/chimney.
See Figure A.
2. Position the increaser into the throat/chimney of the Zero-Clearance Cabinet at a
height slightly higher than the Model 18 will be after installation. NOTE: The
increaser may be a two part slip connector type, if desired.
B. Ceramic Blanket
1. The second method is to use a 6" stainless steel connector (rigid or flex) and a
ceramic blanket (available from your dealer). See Figure B.
2. Cut the connector at least 18" long and tightly wrap the upper portion of the
connector with the ceramic blanket to almost the size of the fireplace throat/chimney.
3. Insert the connector into the fireplace throat/chimney and use additional ceramic
insulation and tightly pack around the connector and the throat/chimney at a height
slightly higher than the Model 18 will be after installation. NOTE: The increaser may
be a two part size connector type if desired.

ALTERNATE FLOOR PROTECTORS MATERIAL
Floor protector must be 3/8" minimum thickness non-combustible material or equivalent.
With the floor protector or hearth extension material specified as one layer of 2" thick brick
with a K* factor of 5.0, you may use alternate materials as long as the K factor(s) is calculated
as follows:
FORMULA: Required thickness = (K of alternate material/K of millboard) x (thickness
of millboard)
EXAMPLE: An alternate inorganic non-combustible millboard with a K of .9375
would require a thickness as follows:
Required thickness = (.9375/5.0) x 2 in.
