THAT IS TOO SMALL OR LARGE IN DIAMETER, OR TOO SHORT, CAN CAUSE
YOUR STOVE TO SPILL SMOKE WHEN THE DOOR IS OPENED.

SECTION I

INTRODUCTION

Your new MODEL 21 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 natural wood, loading wood length way from front to
rear. You should not burn trash or garbage, artificial or paper logs, gift wrapping,
treated or painted wood or any type of coal.

“DO NOT USE CHEMICALS OR FLUIDS TO START THE FIRE.”
“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 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.

A factory-built prefabricated chimney may be used for your unit when installed in compliance
with the manufacturer's specification and uniform building code.

These units may also be used with optional room air blower. To order the optional motor
assemblies you must specify the stove model number and give one of the following part
number:

*Model 21 Motor Assembly—MA 210715

For operation and use of these electrical assemblies, see instructions provided with the motor
assembly kits.

MASONRY INSERT INSTALLATION

The Model 21 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 consid­erations when installing a woodstove. 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. ”DO NOT CONNECT THIS UNIT TO A
CHIMNEY FLUE SERVING ANOTHER APPLIANCE.”

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 .R=0.06

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

protector, 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:
Thermal conductance = C = Btu = W
(hr)(ft²)(°F) (m²)(°K)

Thermal conductance = K = (Btu)(inch) = W = (Btu)

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
450o F- 600o F
7/32" drill bit and drill
Socket/Ratchet Set

INSTALLATION PREPARATION

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 a 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.

FIGURE 2 POSITIONING

POSITIONING THE HEATER

NOTE: If the three suggested installations have been

chosen, certain steps must be followed when installing
the heater into a masonry fireplace.

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, 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.

FIGURE 3 MOUNTING TRIM PANELS

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. 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.

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.

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 unit and slip over the top and sides of trim panels. (Top ends of brass

may need to be trimmed to fit.)

10. If direct connect or positive connect kit is not used, follow instructions in (mounting trim panels, steps 1-4c)

on (Page 8).

11. 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.

12. Using insulation provided, peel and stick to back of panels overlapping fireplace dimensions by 1” on each
side and top. (See Page 8, Figure 3).

13. Next using high heat silicone or furnace cement run heavy bead of caulking around where panels meet the
stove. (See Figure 4).

14. 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.

15. 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

SILICONE

SCREW

FIGURE 4

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 doors. Ensure that
the stove draws properly through the primary draft.

6. Check for smoke leaks around the doors.

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 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

10

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.
