SECTION I
INTRODUCTION
Your new MODEL 74 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.
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 optional motor assembly
you must specify the stove model number and give the following part number:
*Model 74 Motor Assembly—MA 5126715
For operation and use of this electrical assembly, see instructions provided with the motor
assembly kit.

MASONRY INSERT INSTALLATION
The Model 74 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.”

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 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.

POSITIONING THE HEATER
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
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 one of the installation methods shown on
(Page 6.) 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.
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.
8
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. Using insulation provided, peel and stick to back of panels overlapping fireplace dimensions by 1" on each
side and top. (See Figure 4.)
11. Next using high heat silicone or furnace cement run heavy bead of caulking around where panels meet the
stove. (See Figure 4.)
12. 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.
13. 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.
FIGURE 4
FINAL CHECK
1. Recheck the specified clearances.
Remove all foreign material from the firebox area.
2.
Open the primary air draft.
3.
4. Plug the 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 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 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.
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.
