Wood Storage and Care:
KEEP WOOD COVERED AT ALL TIMES. This cannot be over emphasized. Wood stored/stacked, uncovered, exposed to rain and
snow has a higher moisture content, causing the formation of creosote, excess smoke, and it takes longer to ignite as well as producing
poorer fires with lower sustained BTU output. Unseasoned wood ends up costing more in time trying to achieve and maintain proper
temperatures in the firebox, while using more wood with less heat output. Covering the woodpile will keep it dry and offer you the hottest
fires with the greatest BTU output. If you store the wood near your furnace, be sure to maintain proper clearance from the furnace to
prevent a fire hazard. DRY WOOD WILL PRODUCE HOTTER FIRES AND INCREASE BTU OUTPUT.
Follow instructions included with the moisture meter that was supplied with this unit to make sure that you are using seasoned wood to
achieve the cleanest burn and highest efficiency possible.
When using the moisture meter, in addition to following the manufacturer’s instructions, look for readings under 30% moisture content.
Also seasoned wood will be noticeably lighter weight than green wood, generally has darker ends with cracks or splits visible.

Furnace Installation
• Installation is to be performed by a qualified installer.
• Always consult local building inspectors for codes concerning the installation of your furnace.
• Always have access to a backup generator, 2000 watt minimum.
• Use Class “A” HT 2100 All Fuel 6 Inch Chimney for your Shelter Furnace.
• Never use galvanized pipe in your flue connection.
• Inspect the flue periodically for structural integrity.
• Clean the flue regularly to prevent creosote accumulation.
• Never use chemicals or gasoline to start or maintain your fire.
• Never burn garbage, oil, trash, or gasoline in your furnace.
• Never leave the fuel door or ash door open during operation.
• Remove ashes on a daily basis, before ashes reach the grates, to ensure proper air flow.
• 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.
• NEVER UNPLUG THE FURNACE FROM THE POWER SOURCE. THIS WILL CAUSE THE FURNACE TO OVERHEAT. If it is too
warm in the house, lower the temperature on the thermostat; and/or use less fuel.
• Never leave the ash pan or fuel door open in an attempt to regulate the fire. This will overheat the furnace and void the warranty.
• Do not connect this unit to a chimney flue serving another appliance.
• Refer to nameplate on furnace for additional information.
WARNING: RISK OF FIRE
• DO NOT operate with flue draft exceeding .08 water column inches (19.9 Pa).
• DO NOT store fuel or other combustible materials within marked installation clearances.
• Inspect and clean flues and chimney regularly.
• DO NOT operate your furnace with the fuel door or ash door open.
DANGER: Risk of Fire and Explosion. Do not burn garbage, gasoline, naphtha, engine oil, or other flammable liquids/inappropriate
materials.
