SECTION I
INTRODUCTION
Your new MODEL 94NC is a non-catalytic unit designed to meet the most stringent emissions
standards without use of a catalytic combustor. This effect is achieved through use of
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
efficient 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 user, burns the wood. Secondary air is admitted into
firebox through secondary air tubes at top of the firebox. This secondary air burns impurities
in smoke released from initial wood burning. The temperature necessary for this combustion
is maintained through 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 :
11,900 BTU/HR. on Low
42,100 BTU/HR. on High
This unit is equipped with a standard room air blower.

FINAL CHECK
1. Recheck specified clearances.
2. Remove all foreign material from firebox area.
3. Open primary air control.
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 firebox) or in (to control or close off) air into
firebox. (See Figure 7).
4. Plug power cord into a 115V AC outlet. “Do not run cord under unit or in high traffic areas.
5. Place crumpled 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 fire box bottom.”
6. Check for smoke leaks around door.
7. Open door and check for smoke escaping from front of 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 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 rear of manual does not reveal
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.
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

Chimney
This model is designed for connection to any listed 2100º UL103 HT chimneys and parts.
Follow chimneys manufacturer's instructions carefully.
This room heater must be converted to (1) a chimney complying with the requirements for
Type HT chimneys in the Standard for chimneys, Factory-Built, Residential, Type and
Building Heating Appliance, UL 103, or (2) a code approved masonry chimney with a flue
liner. The chimney size should not be less than or more than three times greater than the cross-
sectional area of the flue collar.
Floor Protection:
Floor protection must be 3/8” minimum thickness non-combustible material or equivalent, and
have an R-value of 0.30.
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 greater 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
(Continued on next page)
Page 12
Download from Www.Somanuals.com. All Manuals Search And Download.
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.

that stove draws properly through primary draft.
door. Ensure
6. Check for smoke leaks around door.
CAUTION
Open door and check for smoke escaping from 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 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 rear of manual does not reveal 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
unit will allow these fumes to escape. DO NOT build a large, roaring fire until this curing
is complete or heater finish may be damaged.

SECTION VI
WOOD HEATER SAFETY
Certain safety hazards are inherent in any wood heater installation. You should be aware of
these so that a safe and proper installation can be made.
1. FAULTY CHIMNEY: An older masonry chimney should be thoroughly checked to be sure
there are no holes or weak spots which could allow sparks or hot gases to escape.
2. HEAT CONDUCTION: Placing combustible materials too close to a heater or chimney can
be a fire hazard.
By keeping these particular hazards in mind as you install and use your room heater you can
ensure a safe, reliable installation.
The chimney and chimney connector should be inspected once every two months. Any build-
up of soot should be removed to prevent the risk of a chimney fire. To remove chimney or
chimney connector: Remove screws or fasteners. Remove pipe and clean with steel brush.
Replace chimney or chimney connector, and replace screws and/or fasteners.
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.
CAUTION: Never remove ashes from heater with blower running.
DISPOSAL OF ASHES: Ashes should be placed in a metal container with a tight fitting lid.
The closed container of ashes should be placed on a non-combustible floor or on ground, well
away from all combustible materials pending final disposal. If ashes are disposed of by burial
in soil or otherwise locally dispersed, they should be retained in closed container until all
cinders have thoroughly cooled.
CREOSOTE-FORMATION AND NEED FOR REMOVAL: When wood is burned slowly,
it produces tar and other organic vapors, which combine with expelled moisture to form
creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-burning
fire. As a result, creosote residue accumulates on flue lining. When ignited this creosote
makes an extremely hot fire.

SECTION VII OPERATION
This section of the manual is to help you get maximum efficiency and maximum smoke
(particulate) reduction from your heater. If you should experience any difficulty or have any
questions concerning your heater, contact your dealer for assistance. NOTE: The
manufacturer recommends that for maximum performance burn natural seasoned
hard wood.
Build a fire for maximum efficiency. This model burns wood and extracts heat so efficiently,
a large fire is not necessary. A large fire not only wastes energy, it usually results in home
being too warm for comfort.
The following steps will serve as a guide for operating your stove.
BUILDING A FIRE
1. Open door.
2. Open primary air control. Primary Air Controls: 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 firebox) or in (to control or close off) air into firebox.
3. Twist two pieces of non-colored newspaper into a roll and place them on floor of firebox.
NOTE: “Do not use grate or elevate fire. Build wood fire directly on inner bottom of fire box.”
4. This model is not designed for use of grates, andirons or other methods of supporting fuel.
5. Lay several pieces of dry kindling on top of newspaper.
6. Place three or four small pieces of firewood, 2"-3" in diameter, on top of kindling.
7. Light newspaper in front. Close and latch door. Don't leave fire unattended at this point.
The draft system of heater should start quickly. It may be necessary to preheat chimney
to get draft started. To do this, open door and add newspaper to top rear of wood. Light
or let this paper ignite and allow to burn while holding the door slightly cracked. Once
draft has started, close and lock door. You are over- heating the unit if the chimney and or
connector glows red.
8. NOTE: After embers and a coal bed have been established, load heater with seasoned
natural hard wood, placing it length way front to rear.
NOTE: THE FUELING DOOR MUST REMAIN CLOSED DURING OPERATION.

ROOM AIR BLOWER OPERATION
Your heater is equipped with a room air blower. For operation and wiring see figure 14.
For your convenience your heater is equipped with a rheostat with which you are able to select
air flow. The auto and manual switch will allow you to select the position at which thermostat
will function.
Figure 14
Auto-position: After heater has warmed up and Auto-Manual switch is placed in “Auto”
position and rheostat is in desired position, then fan will automatically come on. When stove
cools off fan will automatically shut-off.
Manual position: You must turn room air blower on and off.
NOTE: Plug power cord into a 115V AC outlet. Set switch to “Manual” and rheostat to
“High” position to ensure motor operates properly. Route cord to prevent damage to
cord insulation from heat and sharp objects. Keep cord out of the way of traffic to
prevent damage caused by tripping, etc.
