FURNACE INSTALLATION INSTALLATION OPTIONS The installation of this furnace includes supplying electrical power, return (fresh air) ductwork, and supply air ductwork. This furnace may be installed in two different confi gurations. 1) Stand alone wood furnace 2) Add-on wood furnace See kit installation section in this manual to ensure proper assembly, installation and operation of your new 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 specifi ed clearances. The clearances will change depending on what kits are installed with your furnace. See the tables and diagram below to determine the clearances for your furnace.
DUCTWORK 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 qualifi ed heating technician and follow his recommendations as to the safest and most effi cient method of installation. This furnace can be installed in three ways, as a stand alone unit, parallel, and in series with an existing furnace.
STAND ALONE INSTALLATION If installing this furnace as a stand alone unit, ensure all local codes and all instructions in this manual are followed, including clearance to combustibles, fl oor protector specifi cations and safety warnings.

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 inside the furnace and inspect for damage, including the fi rebrick as some breakage could occur during shipment.
ELECTRICAL INSTALLATION All electrical connections should be done by a qualifi ed electrician It is recommended to connect the furnace to its own 15 amp 120 Volt circuit from the house power supply 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).
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”...
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 Specifi...
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”...
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, fi restops (where needed), insulation shield, roof fl ashing, chimney cap, etc. Maintain proper clearance to the structure as recommended by the manufacturer.
WOOD HEAT UTILIZATION The top down method of fi re building is recommended for this appliance. After making sure that the stove air intake controls are fully open (completely pull-out towards you), Place the largest pieces of wood on the bottom, laid in parallel and close together.

OPERATION NOTICE: To minimize the risk of smoke spillage when opening the door with a fi re 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.

HEATING WITH YOUR WOOD FURNACE 1) Spread the fi re and coals evenly towards the center of the combustion chamber before loading your furnace fully or adding more wood. 2) Avoid overfi lling the combustion chamber. Air must be allowed to circulate freely through the upper portion of the combustion chamber for the stove to perform best.
If a chimney or creosote fi re occurs, close all dampers immediately. Wait for the fi re to go out and the heater to cool, then inspect the chimney for damage. If no damage results, perform a chimney cleaning to ensure there is no more creosote deposits remaining in the chimney.
SMOKE AND CO MONITORS Burning wood naturally produces smoke and carbon monoxide(CO) emissions. CO is a poisonous gas when exposed to elevated concentrations for extended periods of time. While the modern combustion systems in heaters drastically reduce the amount of CO emitted out the chimney, exposure to the gases in closed or confi ned areas can be dangerous.
MAINTENANCE Your wood furnace is a high effi ciency 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.
