SMOKE WHEN THE DOOR IS OPENED.
SECTION I
INTRODUCTION
Your new Buck 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 secondary
air which is mixed with primary air in the unit’s firebox. For peak performance, we suggest
the use of hard seasoned wood.
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 secondary 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.
Under specific test conditions this heater has been shown to deliver heat at rates ranging from
approximately 11,800 to 40,900 BTU/HR.
These unit may also be used with optional room air blower. To order the optional motor
assembly you must specify the stove model number and give the following part number:
*Model 51 Motor Assembly—MA 5126715
For operation and use of this electrical assembly, see instructions provided with the motor
assembly kit.

SECTION II
MASONRY INSERT INSTALLATION
The Model 51 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. It is not necessary to direct connect this unit unless
installed in an 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
1. The hearth must be of masonry construction and must extend a minimum of 20" in front of
the firebox opening and a minimum of 16" 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.
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 or newspapers
Vacuum cleaner or whisk broom
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/Rachet Set
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 cloths 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. 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. 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 cold air from entering the fireplace
chamber.

INSTALLATION PROCEDURE (Use a Listed Direct or Positive Connect) Not Shown
FIGURE 2 POSITIONING
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 panel 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. Take top trim panel mounting bracket supplied with unit. 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. If not using direct connect kit, continue.
7. 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.
8. Reinstall the top trim panel by sliding the rear lip of the top trim panel underneath the front lip of the mounting
bracket already secured to top of unit.
POSITIONING THE HEATER
NOTE: It is not necessary to direct connect this unit
unless installed in an improperly drawing fireplace or
oversized flue. It is recommended a chimney connector
be installed from the appliance flue collar to the first
fireplace chimney section.
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. Center the heater in the fireplace opening.
MOUNTING THE TRIM PANELS
After the unit is positioned, mark the mounting position
of the trim panels as follows:
1. Set the side trim panels in place, flat against the
face of the fireplace. Mark down the front edge of
the trim panel with a pencil to make a vertical
reference line. (See Figure 3.)
2. 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.
3. Slide the unit out of the fireplace far enough to work
behind the trim panel reference lines.
FIGURE 3 MOUNTING TRIM PANELS

NOTE: Mount the top trim panel so that it sits in front of the top of the side trim panels..
9. Obtain the brass trim kit provided with insert kit and slip over the top and sides of trim panels. (Top ends of
brass may need to be trimmed to fit.)
10. 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.
11. Using insulation provided, peel and stick to back of panels overlapping fireplace dimensions by 1" on each
side and top. (See Figure 4.)
12. Next using high heat silicone or furnace cement run heavy bead of caulking around where panels meet the
stove. (See Figure 4.)
13. 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 loos-
ening the mounting screws and repositioning in the slot. With bar lift stove up in front. Place insulation
across front and the surface of hearth or bottom of fireplace to make complete seal.
14. 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.
FINAL CHECK
1. Recheck the specified clearances.
2. Remove all foreign material from the firebox area.
3. Open the primary air draft.
4. Plug the power cord into a 115V AC outlet if optional motor is being used.
5. Place rumpled pieces of newspaper in the stove. Light it and close the door. Ensure that the
stove draws properly through the primary draft.
6. Check for smoke leaks around the door.
7. Open the door 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 pre-
heated 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.
FIGURE 4

CAUTION
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.

3. Measure up so there will be at least 1/4" rise per foot of horizontal connector pipe,
maintaining clearances to the ceiling as noted in Figure 6. This will give you the center of
the hole for the chimney penetration.
4. After locating the center of the penetration, install the tee-box and chimney as per the
chimney manufacturer's specifications.
5. Connect the chimney collar to the tee-box using #24 ga. minimum blued or black steel
connector pipe. DO NOT use galvanized pipe. Connect each section so the 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 these units to a masonry chimney, determine that the masonry fireplace
wall pass-through connector thimble meets the NFPA-211 Code and local building codes
and is a minimum of 18" from the ceiling. If the connector thimble does not meet
these codes, the pass-through connector must be modified. (See Figure 7.)
Figure 7

Connectors may pass through walls or partitions constructed of combustible material if the
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 the conditions of the listing.
(b) Selected or fabricated in accordance with the conditions and clearances as stated in
the 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.
In addition, a connector to a masonry chimney shall extend through the wall to the inner
face or liner but not beyond, and shall be firmly cemented to masonry.
EXCEPTION: A thimble may be used to facilitate removal of the chimney connector for
cleaning, in which case the thimble shall be permanently cemented in place with high-
temperature cement.
2. Once the through-the-wall thimble codes are met, simply connect the chimney collar to
the 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 the appliance to the chimney.
(b) Connect each section so the crimped end faces downward.
(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 the ceiling above the unit so that the weight is hanging in the
center of the flue exit (A small weight on a string will serve as a plumb bob). Mark the
ceiling where the string is suspended to locate the center of the chimney hole.
2. After locating the center of the hole, install the ceiling support box, chimney flashing
and rain cap.
3. Next, install a New Buck Corporation chimney connector to the flue exit of the heater.
4. Install Double Wall Connector and chimney system per manufacturer’s written operating
instructions. See manufacturer's list of tested pipes in this manual.

FINAL CHECK
1. Recheck the specified clearances.
2. Remove all foreign material from the firebox area.
3. Open the primary air draft.
4. Plug the power cord into a 115V AC outlet when using with optional motor.
5. Place crumpled pieces of newspaper in the stove. Light it and close the door. Ensure
that the stove draws properly through the primary draft.
6. Check for smoke leaks around the door.
CAUTION
Open the door 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.
CAUTION
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.
