Page 6: General Information
Your Shelter Furnace is designed to be either a supplemental or central heating source for your home. This wood burning furnace may be installed in parallel with a properly operating electric, gas or oil-fired central furnace, listed or certified in accordance with a nationally recognized safety standard, and within clearances specified on Shelter Furnace nameplate. -

IMPORTANT: Please keep in mind that different chimney manufacturers’ pipe will not interchange with other brands. A tube of high-temp silicone caulk is included with your furnace. Before using the silicone to install the anchor plate to the top of your Shelter Furnace, ensure the chimney you purchased will fit the anchor plate. -
Page 8: Installing The Anchor Plate
You must install the wall thermostat for the furnace to operate. When the wall thermostat calls for heat, the draft motor will engage, allowing combustion air to flow into the firebox. This causes a hotter fire, increasing the heat in the heat chamber. When the home reaches the selected temperature on the wall thermostat, it will disengage the draft motor and the fire in the firebox will reduce to a low burn until the thermostat calls for another heat cycle. -
Page 9: Chimney Location And Clearances
Chimney Location and Clearances: Requires Class “A” HT 2100 All Fuel 6” Chimney The furnace requires a minimum of 6 feet of chimney. When positioning the furnace, maintain the “10/2 Rule” for the chimney – In order to determine proper chimney height above the roof, measure from the side of the chimney horizontally. As you move up the chimney, the length of the measurement increases. -
Page 10: Wood Storage And Care
• Never use wet, unseasoned wood or wood exposed to a recent rainfall. Doing so causes a rapid accumulation of hazardous creosote, which is a proven cause of flue fires. • Never burn plastics, wood products containing glue, or wood that has been treated with chemical preservatives in your Shelter Furnace. The combustion of these substances may release harmful, toxic gases. -

Page 16: Fuel Recommendations
For the SF4200 model, heat resistant gloves are recommended when loading the furnace. Only use dry, seasoned hardwoods in your Shelter Furnace rather than high resin woods such as pine. Firewood should be cut at least one full season prior to the time of its intended use for optimum heat output. Firewood should be stacked to provide a free flow of air between the logs; this allows... -
Page 17: Heat Dump And Fuse Link System
Draft Blower: The draft blower plays an important role in the operation of your Shelter Furnace. When the wall thermostat calls for heat, the draft motor turns on and supplies fresh air into the firebox producing a hotter fire, which in turn provides more heat in the heat chamber. The heat is then sent through the duct system throughout your home. -
Page 18: Creosote Prevention
For safety and efficiency, it is recommended that the chimney system be inspected and cleaned prior to each heating season. Power Failure: In case of power failure, to prevent your Shelter Furnace from over-heating and causing damage to the electrical components, follow these steps: • Make sure the ash door is closed. - Page 19 ALWAYS: • Locate the Shelter Furnace on a level, solid, non-combustible surface. • Follow local codes concerning installation requirements. • Connect power cord to a grounded 110 outlet. • Connect cold air return to the house. • Use Class “A” HT2100 All Fuel 6 inch chimney.
