Unpacking And Preassemble UNPACKING 1. Remove all packaging from the furnace. 2. Remove the supplied parts from the furnace. BRICK ALIGNMENT Inspect for any damage. Ensure that the bricks and ash plug are positioned correctly and not broken (see illustration for proper brick arrangement). Proper Fire Brick Alignment TOOLS AND MATERIALS NEEDED FOR INSTALLATION The following is a list of tools and materials needed to install your furnace. • 7/16” socket wrench.
Furnace Installation INSTALLATION OPTIONS P The installation of this furnace includes supplying electrical power, return (fresh air) ductwork, and supply air P ductwork. This furnace may be installed in two different configurations. 1. Stand alone wood furnace 2. Add-on wood furnace S S S See kit installation section in this manual to ensure proper assembly, installation and operation of your new S furnace.
MAINTENANCE CLEARANCES Your furnace has recommended minimum maintenance clearance requirements. These clearances insure that there is adequate room to preform maintenance and service your furnace. DO NOT store fuel within the specified clearances. See the table and diagram below to determine the clearances for your furnace.
Duct Work Installation We strongly recommend that the hot air ductwork be installed by a home heating specialist. If doing the installation yourself, before you decide which installation will best suit your needs, consult a qualified heating technician and follow his recommendations as to the safest and most efficient method of installation. This furnace can be installed in three ways, as a stand alone unit, parallel, and in series with an existing furnace.

Accessory Installation ASSEMBLY OF FURNACE Your furnace requires the following items to be assembled or installed by the service person: Blowers and Blower Controls Electrical Connections 1. Remove all parts from the unit (blowers, thermodisc, and all wiring) and inspect for damage, including the firebrick as some breakage could occur during shipment. 2. Install the thermodisc on rear of furnace cabinet with the two screws provided.
Electrical Installation All electrical connections should be done by a qualified electrician It is recommended to connect the furnace to its own 15 amp 120 Volt circuit from the house power supply 105°C NOTE: Wire leads from the distribution blower are usually BOTH BLACK. Makes no difference which leads from the motor(s) connects to the corresponding leads coming out of the conduit.
Chimney Installation CHIMNEY Your wood furnace may be hooked up with a factory built or masonry chimney, matching the diameter of the exhaust. If you are using a factory built chimney, it must comply with UL 103 or CSA-B365 standard; therefore it must be a Type HT (2100°F). It is extremely important that it be installed according to the manufacturer’s specifications. If you are using a masonry chimney, it is important that it be built in compliance with the specifications of the National Building Code.
MASONRY CHIMNEY Ensure that a masonry chimney meets the minimum standards of the National Fire Protection Association (NFPA) by having it inspected by a professional. Make sure there are no cracks, loose mortar or other signs of deterioration and blockage. Have the chimney cleaned before the furnace is installed and operated. When connecting the furnace through a combustible wall to a masonry chimney, special methods are needed as explained in the “Combustible Wall Chimney Connector Pass-Throughs” Section.
COMBUSTIBLE WALL CHIMNEY CONNECTOR PASS-THROUGHS Method A. 12” (304.8 mm) Clearance to Combustible Wall Member: Using a minimum thickness 3.5” (89 mm) brick and a 5/8” (15.9 mm) minimum wall thickness clay liner, construct a wall pass-through. The clay liner must conform to ASTM C315 (Standard Specification for Clay Fire Linings) or its equivalent. Keep a minimum of 12” (304.8 mm) of brick masonry between the clay liner and wall combustibles.
CHIMNEY CONNECTOR Your chimney connector and chimney must have the same diameter as the furnace outlet. If this is not the case, we recommend you contact your dealer in order to insure there will be no problem with the draft. The furnace pipe must be made of aluminized or cold roll steel with a minimum thickness of 0.021” or 0.53 mm. It is strictly forbidden to use galvanized steel. Your connector should be assembled in such a way that the male section (crimped end) of the pipe faces down.
FACTORY BUILT CHIMNEY When a metal prefabricated chimney is used, the manufacturer’s installation instructions must be followed. You must also purchase (from the same manufacturer) and install the ceiling support package or wall pass-through and “T” section package, firestops (where needed), insulation shield, roof flashing, chimney cap, etc. Maintain proper clearance to the structure as recommended by the manufacturer.
OPERATING THE PRIMARY AND SECONDARY AIR SETTINGS Primary air- is the driving air supply that feeds the fire in the heater. This air is introduced through the damper in the feed door to sustain the combustion. Secondary air – is the air supply that is typically introduced above the fire to effectively “re-burn” the smoke created in the primary combustion before the exhaust gasses exit the stove.
Operation The top down method of fire building is recommended for this appliance. After making sure that the stove air intake controls are fully open (open all three air controls to there maximum setting). Place the largest pieces of wood on the bottom, laid in parallel and close together. Smaller pieces are placed in a second layer, crossways to the first. A third layer of still smaller pieces is laid crossways to the second, this time with some spaces between.
NOTICE: To minimize the risk of smoke spillage when opening the door with a fire in your furnace, crack the door open no more than 1” and wait for at least 10 seconds before opening it more to allow pressure stabilization inside the furnace. Smaller pieces of wood will dry faster. All logs exceeding 6” in diameter should be split. The wood should not be stored directly on the ground. Air should circulate through the cord.
OPERATION Controlled combustion is the most efficient technique for wood heating because it enables you to select the type of combustion you want for each given situation. The wood will burn slowly if the wood furnace air intake control’s are adjusted to reduce the oxygen supply in the combustion chamber to a minimum. On the other hand, wood will burn quickly if the air control’s are adjusted to admit a larger quantity of oxygen in the combustion chamber.
CAUTIONS: • Ashes could contain hot embers even after two days without operating the furnace. • The ash pan can become very hot. Wear gloves to prevent injury. • Never burn the furnace with the ash trap open. This would result in over firing the furnace. Damage to the furnace and even house fire may result. TAMPER WARNING This wood heater has a manufacturer-set minimum low burn rate that must not be altered.
Maintenance Your wood furnace is a high efficiency furnace and therefore requires little maintenance. It is important to perform a visual inspection of the furnace every time it is emptied, in order to insure that no parts have been damaged, in which case repairs must be performed immediately. Inspect and clean the chimney and connector pipe periodically for creosote buildup or obstructions.
