Furnace Clearances and Operation
Before beginning your installation, consult with local authorities regarding the codes governing all such installations. DO NOT connect
your Shelter Furnace to any flue that is servicing ANY other appliances.
The Shelter Furnace may be placed outdoors or indoors. If outdoors, it must be placed on a level, non-combustible base, preferably
a 4’ x 8’ concrete pad, as close to the home as clearances to combustibles permit – do not place the furnace more than 30 feet from
the house. The furnace must be connected to a grounded electrical circuit with access to a backup generator (2000 watt minimum). If
locating the furnace more than 10’ from the home, a minimum of 6’ of Class “A” HT 2100 All Fuel 6 inch Chimney Pipe is required. If
installing indoors, your furnace must be placed on a non-combustible floor. Air for combustion must be provided into the room where the
furnace is located. Allow air free access to furnace for combustion and ventilation.
Maintain the following clearances:
• Front = 48 inches
• Rear = 12 inches
• Sides = 6 inches
• Heat Duct = 6 inches for the first 16 inches from the back of the furnace, and 3 inches beyond
Class “A” HT 2100 All Fuel 6 inch Chimney Pipe is required for optimum performance and must maintain a 2 inch clearance from
combustibles. The Shelter Furnace will ship with an anchor plate and four #10 ¾” galvanized screws with washers and gaskets to match
the chimney your dealer supplies. If the anchor plate provided with your furnace does not fit the chimney your dealer has in stock, please
call our toll free number, 1-800-875-4788 for assistance.
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.
Guy wire brackets are attached to the sides of the Shelter Furnace. A heavy gauge of stainless steel wire can be purchased from your
dealer or at a local hardware store to use as guy wire to help support your chimney. Attach the appropriate chimney pipe lengths to the
adaptor plate finishing with a chimney cap. IMPORTANT: Your furnace requires its own chimney system and cannot share a flue with any
other product. DO NOT USE GALVANIZED OR BLACK PIPE TO VENT YOUR FURNACE.
Once you have met local requirements governing the installation and positioning of the furnace, install the Electrical Control Kit. Open
the Electrical Control Kit and confirm that all items were shipped with your Shelter Furnace. IMPORTANT: ENSURE THE POWER CORD
IS PLUGGED INTO A GROUNDED ELECTRICAL SUPPLY. Do NOT connect the furnace to your ductwork at this time. Build a small fire
– DO NOT fill the firebox to full capacity during the initial firing. Your new furnace has a protective coating of oil or paint on the surface,
which could produce smoke or odors during the initial firing and will burn off. Allow adequate ventilation during this initial, break-in firing
to let any odors escape. This initial firing also allows the metals to cure. After successfully completing the initial firing, you are ready to
attach the hot air duct and cold air return to complete your installation. See diagram below.
This wood heater has a manufacturer-set minimum low burn rate that must not be altered. It is against federal regulations to alter this
setting or otherwise operate this wood heater in a manner inconsistent with operating instructions in this manual.
