ALWAYS KEEP YOUR WOOD COVERED YEAR ROUND; DRY WOOD WILL PRODUCE MORE BTU OUTPUT AND LONGER BURN
TIMES.
This EPA-Approved Shelter Furnace is an airtight central outdoor furnace engineered to accommodate the heating requirements of the
average sized home, even during winter’s coldest months, with a heat output range up to 140,000 BTUs. It is constructed of high grade,
heavy gauge steel and is continuously welded to assure the utmost in structural strength. In addition, the heat exchanger is lined with
insulated stainless steel to ensure many years of energy efficient service.
The design of the secondary combustion chamber increases fuel efficiency by creating a “secondary burn” of smoke and wood gases
before they are vented up the chimney. By sending the gases back through the secondary combustion chamber, less fuel is wasted, the
furnace burns at a higher efficiency, and for longer burn times.
The cast iron door is custom fitted to provide an airtight seal, greatly extending the burn time and ensuring maximum efficiency in fuel
consumption. The heavy-duty cast iron grates aid in convenient ash removal and reduce maintenance; the insulated wrap-around sides
are designed for maximum heat transfer.
For total comfort and convenience, a thermostatically controlled 1800 CFM circulation blower system has been installed. The blower
draws the cold air from the home, across the heat chamber before going through the hot air duct and returning the warm air to your home.
This fully automatic blower disperses heat rapidly to your home, minimizing recovery time. Average burn time per load of fuel is 8 to
12 hours depending on wood type and condition, desired temperature within the home and amount of fuel. We have incorporated all
of these features as standard equipment, offering you the most efficient, durable and affordable appliance possible. Abnormally cold
weather could reduce the burn time.
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. When in a parallel installation the static
pressure of the central furnace plenum may not exceed 0.15 water column inches and the maximum setting on central furnace limit
switch is 182°F. With the Shelter Furnace in an “Interconnection Arrangement” your furnace should be upstream of the central furnace.
The Shelter Furnace warm air supply should never be connected to return air for the central furnace. A qualified installer should perform
the installation.
This is a wood burning furnace – it cannot be turned “off and on” to control the furnace temperature like gas or electric furnaces. Once
the fire is established, it has to burn until it burns itself out.
This wood heater needs periodic inspection and repair for proper operation. It is against federal regulations to operate this wood heater in
a manner inconsistent with operating instructions in this manual. Efficiency was determined using the higher heating value of the fuel per
B415.1-10 testing requirements. Dry seasoned wood will develop greater BTU output. A well-insulated dwelling will always lead to better
results and overall improved fuel usage efficiency.
