CAUTION

YOUR CHIMNEY MUST BE CORRECTLY SIZED. A CHIMNEY 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 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.

SECTION II

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.”

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.

Page 10

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.

Open the primary air draft.

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.

Chimney

This model is designed for connection to the following listed 2100º UL103 HT chimneys and parts. Follow chimneys manufacturer's instructions carefully.

Simpson Duravent Metal Fab Security Airjet Selkirk Metal Bestos Jakes Evans

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.

Floor Protection:

Floor protection must be 3/8” minimum thickness non-combustible material or equivalent.

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

Page 15

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) (hr)(ft²)(°f) (m)(°K) (hr)(tf)(°F)

Thermal conductance = R = (ft²)(hr)(°F) = (m²)(°K) Btu W

Install in accordance with 24 CFR, Part 3280 (HUD).

FLOOR PROTECTION

Floor protector must be 3/8" minimum thickness non-combustible material or equivalent.

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.

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, therefor 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) (hr)(ft²)(°f) (m)(°K) (hr)(tf)(°F)

Thermal conductance = R = (ft²)(hr)(°F) = (m²)(°K) Btu W

Install in accordance with 24 CFR, Part 3280 (HUD).

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 buildup 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.

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 the ground, well away from all combustible materials pending final disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the 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 the flue lining. When ignited this creosote makes an extremely hot fire.

SECTION VII

OPERATION

This section of the manual is to help you get the 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 seasoned natural 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 the home being too warm for comfort.

The following steps will serve as a guide for operating your stove.

BUILDING A FIRE

1. Open the door.

2. Open the primary air control under hearth, push in. To close pull all the way out.

3. Twist two pieces of non-colored newspaper into a roll and place them on the floor of the firebox.

4. This model is not designed for the use of grates, andirons or other methods of supporting the fuel.

5. Lay several pieces of dry kindling on top of the newspaper.

6. Place three or four small pieces of firewood, 2"-3" in diameter, on top of the kindling.

7. Light the newspaper in the front. Close and latch the door. Don't leave the fire unattended at this point. The draft system of the heater should start quickly. It may be necessary to preheat the chimney to get the draft started. To do this, open the door and add newspaper to the top rear of the wood. Light or let this paper ignite and allow to burn while holding the door slightly cracked. Once the draft has started, close and lock the door. You are overheating the unit if the chimney and or connector glows red.

8. NOTE: After embers and a coal bed have been established, load the heater with

seasoned natural hard wood, placing it length way front to rear.

NOTE: THE FUELING DOOR MUST REMAIN CLOSED DURING OPERATION.

BURN RATE LOW MED-LOW MED-HI HI AIR SETTINGS 5/16” 3/8” 5/8” WIDE OPEN

NOTE: If the optional blower is being used on the Model 74, operate the blower in the “OFF” position for the first thirty (30) minutes after starting the fire and in the “OFF” position for thirty (30) minutes after refueling the fire. Set fan speed according to desired Heat output. Do not run power cord underneath heater, or in walk way or heavy traffic areas.
