Your Furnace is designed to be installed in a parallel
air flow arrangement with a gas or oil-fired forced air
upflow-type central furnace, or it may be installed as a
central furnace.
HOW THE FURNACE FUNCTIONS
This furnace is designed to be a supplemental or
central heating source for your home. This solid fuel
furnace may be installed in conjunction with a properly
operating central furnace that is listed or certified in
accordance with nationally recognized safety standards
and equipped with the required controls and other safety
features and which has been installed in accordance with
appropriate standards of the National Fire Protection
Association with installation clearances specified in the
furnace nameplate marking. The installation must be
accomplished by a qualified agency (one who is engaged
in, and is responsible for, or is thoroughly familiar with
the installation and operation of the gas, oil, and solid
fuel burning heating appliances, who is experienced
in such work, familiar with all the requirements of the
authority having jurisdiction.) The installation shall be
in strict accordance with the manufacturer's installation
instructions furnished with the solid fuel furnace. The
chimney connector of the furnace is to be installed to
provide clearances to combustible material not less than
specified in the individual classifications and marked on
the furnace. The chimney connector must be connected
to a chimney suitable for use with residential type or
building heating appliances which burn solid fuel. The
Furnace is designed to operate in either parallel or series
air flow arrangement with the central furnace or as a
central furnace.
CENTRAL FURNACE INSTALLATION
As a central furnace, the unit functions independently
of any other system. The blower will come on when the
plenum temperature reaches the setting on the blower
control.
PARALLEL INSTALLATION (U.S. ONLY)
The design is such that when the blower comes on, the
blower on the central system also comes on. The blower
will only come on when the temperature in the plenum
has reached the setting on the blower control. This is to
ensure that there is sufficient warm air in the system to
make it efficient for the unit to operate. When the central
system thermostat calls for heat, the central system will
operate by the burner igniting and the blower coming on. It
is possible that both systems will operate simultaneously.
It is recommended that for the most efficient use of this
furnace, that it be fired as much as possible in order to
reduce the demand on your existing central heating
system. This unit has an optional forced draft kit that
operates from a wall thermostat. When the temperature
falls below the setting on the wall thermostat, the forced
draft will come on (U.S. Stove Option 11/DIKL) The warm
air supply outlet of the this furnace shall not be connected
to the cold air return of the central furnace, because the
possibility exists of components of the central furnace
overheating and causing the central furnace to operate
other than is intended.
SERIES INSTALLATION
This type of installation uses only the blowers of the
existing central furnace. The solid fuel fan/limit control
must also control the functions of the existing furnace. All
electrical power must come from a single branch circuit.
LOCATING THE FURNACE
1. The furnace should be located in the same room
as the central system and as close as possible, but
not closer than 9". There should be no wall between
the furnace and the warm air outlet duct that is
connected directly to the warm air outlet plenum of
the central furnace.
2. Place the furnace on a noncombustible floor.
3. Ensure you have the clearances shown in this
manual from the furnace and the connector pipe
to combustible surfaces. If you have a solid brick
or stone wall behind your furnace, you can place
the furnace as close as you wish to the wall. If the
wall is only faced with brick or stone, treat it as a
combustible wall.
