SECTION I
INTRODUCTION
The 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 firebox.
For peak performance, we suggest the use of natural seasoned hard wood. Load wood
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 firebox. This secondary air burns impurities in
the 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.
CAUTION
YOUR CHIMNEY OR FLUE MUST BE CORRECTLY SIZED. A CHIMNEY OR FLUE
THAT IS TOO SMALL OR LARGE IN DIAMETER OR TOO SHORT CAN CAUSE YOUR
STOVE TO SPILL SMOKE WHEN THE DOOR IS OPENED.

INSTALLATION PROCEDURE
(Use a chimney connector or a Listed Direct or Positive Connect) (See Page 6).
POSITIONING HEATER
When positioning heater, the following conditions
MUST be met. (See Figure 5).
1. The front of flue opening must be positioned
BEHIND rear edge of the lintel to ensure proper
draft. (See Figure 5).
2. Center heater in fireplace opening.
MOUNTING TRIM PANELS
NOTE: Mount top trim panel so that it sits in front of
top of side trim panels.
After unit is positioned, mark mounting position of trim
panels as follows:
1. Place side trim panels flat against face of fireplace.
Mark down front edge of trim panel with a pencil to
make a vertical reference line. (See Figure 6).
2. Set top (long) trim panel in place 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 6 MOUNTING TRIM PANELS
FIGURE 5 POSITIONING
FLUE OPENING
FRONT OF FIREPLACE
4. Mount side trim panels. (See Figure 6).
a. Position trim panel on reference line.
b. Drill mounting holes in center of trim panel mounting brackets to allow for adjustment in and out if neces-
sary.
c. Mount trim panel using self-tapping screws provided.
5. Place top panel back on reference mark. Take the top trim panel mounting bracket, position bracket so it over-
laps 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 installation procedures listed. Install heater and connect kit in fireplace. If not using one of
installation methods shown on (Page 7), then continue.
7. Slide unit back into fireplace. Check to be sure that trim panels are properly positioned so they lie flat against
front of fireplace. If one or more of panels is out of position, slide unit out and reset by loosening the
mounting screws and repositioning in the slot. Reinstall top trim panel by sliding rear lip of top trim panel
underneath front lip of mounting bracket.

Page 9
8. Obtain outer trim kit provided with insert kit. Slip it over top and sides of trim panels.(See Figure 7). (Top
ends of outer trim may need to be trimmed to fit).
9. Using insulation provided, peel and stick to back of panels. It will overlap fireplace dimensions by 1" on each
side and top. (See Figure 8).
10. Using high heat silicone or furnace cement run heavy bead of caulking around where back of panels meet
stove. (See Figure 8).
11. Slide unit back into fireplace. Check to be sure that trim panels (and outer trim) 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. Lift stove up in front by using the bar. Place insulation across the bottom and
surface of hearth, or bottom of fireplace, to make complete seal.
12. 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. 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) to let 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. 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.

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 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 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 13
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).
DETERMINING CHIMNEY LOCATION
A. CEILING EXIT (Using 8” inch Diameter Residential Single Wall (minimum 24-ga.)
Black Chimney Connector and any listed 2100 UL 103 HT type Chimney System ).
(See Page 14).
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 string is

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.
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 fire. 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.
