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 DOOR IS OPENED. SECTION I INTRODUCTION Your new MODEL 74 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.
SECTION II MASONRY INSERT INSTALLATION The Model 74 may be installed using an all masonry fireplace built in accordance with Uniform Building Code and National Fire Protection Association (NFPA). The first step in this type of installation is to determine acceptability of fireplace and chimney for use with a woodstove. Both construction and condition of fireplace are important considerations when installing a woodstove.
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.
SAFETY NOTICE If this appliance is not properly installed, a house fire may result. For your safety, follow the installation directions. Contact local building or fire officials about restrictions and installation inspection requirements in your area.
INSTALLATION PROCEDURE (Use a chimney connector or a Listed Direct or Positive Connect) (See Page 7). POSITIONING HEATER When positioning heater, following conditions MUST be met! (See Figure 2). 1. The front of damper opening must be positioned BEHIND rear edge of lintel to ensure proper draft. (See Figure 2). 2. Center heater in fireplace opening. FIGURE 2 POSITIONING MOUNTING TRIM PANELS Afterunit is positioned, mark the mounting position of the trim panels as follows: 1. 2. 3. 4. 5. 6. 7. 8.
9. NOTE: Mount top trim panel so that it sits in front of top of side trim panels. Obtain brass trim kit provided with insert kit and slip over top and sides of trim panels. Top ends of brass may need to be trimmed to fit (See Figure 4). 10. Using insulation provided, peel and stick to back of panels overlapping fireplace dimensions by 1" on each side and top. (See Figure 4A). 11. Next using high heat silicone or furnace cement, run heavy bead of caulking around where panels meet stove. (See Figure 4A).
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 HEATER FINISH MAY BE DAMAGED.
SECTION III PRE-FAB INSERT INSTALLATION The Model 74 has been tested with the following UL listed manufactured Pre-Fab Fireplaces: Heatilator Tempco Marco Woodside Security Preway FMI Majestic The Model 74 will fit any of models that are large enough to accept them. NOTE: A full chimney liner is required in a Zero Clearance or pre-fab fireplace. NOTE: The ash lip, smoke baffle and smoke shelf may be removed if necessary to provide room for these models.
SECTION IV RESIDENTIAL FREESTANDING INSTALLATION Select an installation location that will give best airflow from front of heater to remainder of the home. PREPARING STOVE FOR INSTALLATION 1. Inspect unit for any obvious physical damage. 2. Plug power cord into a 115V AC outlet to test motor and fan. Do not run power cord under unit or in high traffic areas. 3. Check primary air draft control to ensure that it slides freely.(See Figure 4). 4. Remove any items from within the firebox.
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. Floor Protection: When installing freestanding heater, a floor protector must be use.
CAUTION SPECIAL METHODS ARE REQUIRED WHEN PASSING THROUGH A WALL OR CEILING. SEE INSTRUCTIONS AND BUILDING CODES. DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE. DETERMINING CHIMNEY LOCATION A. CEILING EXIT (USING SINGLE WALL (minimum 24ga.) pipe and 2100° UL 103 HT type chimney system listed with manufacturer in this section of manual.) (See Page 13). 1. Suspend a plumb bob from ceiling above unit so that weight is hanging in center of flue exit.

3. Measure up so there will be at least 1/4" rise per foot of horizontal connector pipe, maintaining clearances to ceiling as noted in (Figure 6 Page 15). This will give you center of hole for chimney penetration. 4. After locating center of penetration, install tee-box and chimney, as per chimney manufacturer's specifications. 5. Connect chimney connector to tee-box using #24 ga. minimum blue or black steel connector pipe. DO NOT use galvanized pipe.
Connectors may pass through walls or partitions constructed of combustible material if connector is: (a) Either listed for wall pass-through or is routed through a device listed for wall passthrough and is installed in accordance with conditions of listing. (b) Selected or fabricated in accordance with conditions and clearances as stated in NFPA211 Code.

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.
SECTION VII OPERATION This section of 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. NOTE: Soft woods such as pine, create more creosote, clogging of chimney and produce a less efficient burn performance.
