SMOKE WHEN THE DOOR IS OPENED.
SECTION I
INTRODUCTION
Your Buck Stove is 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 unit's firebox.
For peak performance, we suggest the use of natural seasoned hard wood, loading wood
length way from front to rear.
NOTE: Soft woods such as pine, create more creosote, clogging of chimney and produce a less effi-
cient burn performance.
You should not burn trash or garbage, artificial or paper logs, gift wrapping, treated or
painted wood or any type of coal, or flammable fluids.
The primary air, which is controlled by the user, burns the wood. Secondary air is admitted into
firebox through secondary air tubes at top of firebox. This secondary air burns impurities in
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 use of these
electrical assemblies, see instructions provided in this manual starting on page 30.

SECTION II
MASONRY INSERT INSTALLATION
The Model 81 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 acceptability of fireplace and chimney for use with a
woodstove. Both construction and condition of fireplace are important consid-
erations when installing a woodstove. The chimney should extend at least 3' above roof and
at least 2' above any point of roof within 10'.
CAUTION
REMEMBER TO HAVE YOUR CHIMNEY INSPECTED FOR LEAKS AND BLOCKAGE
BEFORE YOU INSTALL YOUR STOVE. “DO NOT CONNECT THIS UNIT TO A
CHIMNEY FLUE SERVING ANOTHER APPLIANCE.”

MINIMUM CLEARANCES
Floor Protection:
When installing freestanding heater, a floor protector must be use. Floor protection must be
3/8” minimum thickness non-combustible material or equivalent.
How to use alternate materials and how to calculate equivalent thickness
An easy means of determining if a proposed alternate floor protector meets requirements listed
in the appliance manual is to follow this procedure:
1. Convert specification to R-value:
R-value is given—no conversion is needed.
K-factor is given with a required thickness (T) in inches:
C-factor is given: R=1/C
2. Determine the R-value of the proposed alternate floor protector.
Use the formula in step (1) to convert values not expressed as “R”
For multiple layers, add R-values of each layer to determine the overall R-value.
3. If the overall R-value of the system is grater than the R-value of the specified floor protec-
tor, the alternate is acceptable.
Example:
The specified floor protector should be 3/4” thick material with a K-factor of 0.84.
The proposed alternate is 4” brick with a C-factor of 1.25 over 1/8” mineral board with a
K-factor of 0.29.
Step (a): Use formula above to convert specification to R-value. R= 1/K x T = 1/0.84 x .75 =
0.893
Step (b): Calculate R of proposed system. 4” brick of C=1.25, therefore Rbrick = 1/C = 1/1.25
=0.80 1/8” mineral board of K = 0.29, therefore Rmin.bd. =1/029 x0.125 = 0.431
Step (c): Compare proposed system R of 1.231 to specified R of 0.893. Since proposed
system R is greater than required , the system is acceptable.
Definitions:
Install in accordance with 24 CFR, Part 3280 (HUD).

Flashlight
1 tube of RTV silicone, Code 103 or 106, or high temperature rubber cement rated between
450oF- 600o F
7/32" drill bit and drill
Socket/Ratchet Set
INSTALLATION PREPARATION
Fireplace:
1. Locate furniture and other materials away from front of fireplace to allow free access to
fireplace.
2. Cover hearth and adjacent floor areas with a drop cloths to protect from soiling or marring
surface.
3. Remove existing fireplace damper plate.
4. Thoroughly clean fireplace of ashes and soot.
5. Check chimney and smoke chamber for excessive buildup of creosote or soot. Also, check
for obstructions, such as bird’s nests. If chimney is excessively dirty, clean it or have
someone clean it professionally BEFORE installing or using room heater.
6. If fireplace has an ash dump or outside air provision, these must be sealed off with metal or
tightly packed non-combustible insulation to prevent cold air from entering fireplace
chamber.

panels as follows:
1. Place side trim panels flat against face of fireplace.
Mark front edge of trim panel with a pencil to make a
vertical reference line. (See Figure 3).
2. Place top (long) trim panel on top of unit.
The panel should be flat against the outside face
of fireplace and standing vertically. Mark along
lower edge of trim panel with a pencil to make a
reference line for mounting.
3. Slide unit out of fireplace far enough to work
behind trim panel reference lines. FIGURE 3 MOUNTING TRIM PANELS
FIGURE 2 POSITIONING
4. Mount side trim panels. (See Figure 3).
a. Position side trim panel on reference line.
b. Drill mounting holes in center of side trim panel mounting brackets to allow for adjustment in and out if
necessary.
c. Mount trim panel using self-tapping screws provided.
5. Place top trim panel on reference mark. Top trim panel mounting bracket (supplied) must overlap rear lip of
top trim panel. Drill mounting holes in top of stove using holes in bracket as guide. Tighten screws.
6. Follow installation procedures in listed direct connect or positive connect kit you are using and install heater
and connect kit in fireplace. If not using one of installation methods shown on Page 8, continue.
7. Slide unit back into fireplace. Check to be sure that trim panels are properly positioned and lie flat against
front of fireplace. If one or more of panels is out of position, slide unit out and reset by loosening mounting

NOTE: Mount top trim panel so that it sits in front of top of side trim panels.
9. Obtain brass trim kit provided with insert kit and slip over top and sides of trim panels. Top ends of brass may
need to be trimmed to fit (See Figure 4).
10. Using insulation provided, peel and stick to back of panels overlapping fireplace dimensions by 1" on each
side and top. (See Figure 4A).
11. Next using high heat silicone or furnace cement run heavy bead of caulking around where panels meet the
stove. (See Figure 4A).
12. Slide unit back into fireplace. Check to be sure that trim panels (and brass) are properly positioned and lie flat
against front of fireplace. If panels are out of position, slide unit out and reset by loosening mounting screws
and repositioning in slot. With bar lift stove up in front. Place insulation across front and surface of hearth or
bottom of fireplace to make complete seal.
13. To check seal of panels, use candle flame and go around entire area sealed by silicone and insulation. If flame
leans toward inside of fireplace, add additional insulation. This ensures an airtight seal.
FINAL CHECK
1. Recheck specified clearances.
2. Remove all foreign material from firebox area.
3. Primary Air Control: The primary air intake draft control is located at right bottom side of hearth. It is
operated by moving handle out to open (to allow air into the firebox) or in (to control or close off) air into
firebox. (See Figure 4).
4. Plug power cord into a 115V AC outlet if optional motor is being used. “Do not run power cord under unit
or in high traffic areas.
5. Place rumpled pieces of newspaper in stove. Light it and close door. Ensure that stove draws properly through
primary draft.
NOTE: “Do not use grate or elevate fire. Build wood fire directly on inner bottom of fire box.”
6. Check for smoke leaks around door.
7. Open door and check for smoke escaping from front of stove. Smoking usually ndicates a defective or poorly
positioned chimney. Some chimneys with a marginal draft can be pre-heated by lighting newspaper and
holding it near open damper with a poker or fire tong. Once chimney heats up, a proper draft can usually be
obtained.
If a thorough review of Troubleshooting Guide in the rear of manual does not reveal problem, contact your dealer
for assistance.

ALTERNATE FLOOR PROTECTORS MATERIAL
Floor Protection:
When installing freestanding heater, a floor protector must be use. Floor protection must be
3/8” minimum thickness non-combustible material or equivalent.
How to use alternate materials and how to calculate equivalent thickness
An easy means of determining if a proposed alternate floor protector meets requirements listed
in the appliance manual is to follow this procedure:
1. Convert specification to R-value:
R-value is given—no conversion is needed.
K-factor is given with a required thickness (T) in inches:
C-factor is given: R=1/C
2. Determine the R-value of the proposed alternate floor protector.
Use the formula in step (1) to convert values not expressed as “R”
For multiple layers, add R-values of each layer to determine the overall R-value.
3. If the overall R-value of the system is grater than the R-value of the specified floor protec-
tor, the alternate is acceptable.
Example:
The specified floor protector should be 3/4” thick material with a K-factor of 0.84.
The proposed alternate is 4” brick with a C-factor of 1.25 over 1/8” mineral board with a
K-factor of 0.29.
Step (a): Use formula above to convert specification to R-value. R= 1/K x T = 1/0.84 x .75 =
0.893
Step (b): Calculate R of proposed system. 4” brick of C=1.25, therefore Rbrick = 1/C = 1/1.25
=0.80 1/8” mineral board of K = 0.29, therefore Rmin.bd. =1/029 x0.125 = 0.431
Step (c): Compare proposed system R of 1.231 to specified R of 0.893. Since proposed
system R is greater than required , the system is acceptable.

manufacturer's specifications.
5. Connect chimney collar to tee-box using #24 ga. minimum blued or black steel connector
pipe. (DO NOT USE GALVANIZED PIPE). Connect each section so crimped end faces
downward and secure each section to each other using three (3) sheet metal screws or rivets.
C. Wall Exit Into Masonry (Using Single Wall Pipe)
1. Before connecting this unit to a masonry chimney, determine that masonry fireplace wall
pass-through connector thimble meets NFPA-211 Code and local building codes and is
a minimum of 18" from ceiling. If connector thimble does not meet these codes, the pass
-through connector must be modified. (See Figure 8).
Figure 8
Connectors may pass through walls or partitions constructed of combustible material if
connector is:
(a) Either listed for wall pass-through or is routed through a device listed for wall pass-
through and is installed in accordance with conditions of listing.
(b) Selected or fabricated in accordance with conditions and clearances as stated in NFPA
-211 Code. Any unexposed metal that is used as part of a wall pass-through system
and is exposed to flue gases shall be constructed of stainless steel or other equivalent
material that will resist corrosion, softening, or cracking from flue gases at temperatures
up to 1800oF.
Page 17

NOTE: In addition, a connector to a masonry chimney shall extend through wall to inner
face or liner but not beyond and shall be firmly cemented to masonry.
EXCEPTION: A thimble may be used to facilitate removal of chimney connector for
cleaning, in which case, thimble shall be permanently cemented in place with high-temperature
cement.
2. Once through-the-wall thimble codes are met, simply connectchimney collar to wall pass-
through connector using #24 ga. minimum, blued or black steel connector pipe as follows:
(a) Maintain 1/4" rise per foot (horizontal length) from appliance to chimney.
(b) Connect each section so crimped end faces downward or back toward unit.
(c) Secure each section to each other using at least three (3) sheet metal screws or rivets.
(d) Use three (3) sheet metal screws to fasten pipe to connector collar on heater.
D. Ceiling Exit-Close Clearance
1. Suspend a plumb bob from ceiling above unit so that weight is hanging in center of
flue exit. (A small weight on a string will serve as a plumb bob). Mark ceiling where
