FURNACE DESCRIPTION & INSTALLATION OPTIONS
Your NORSEMAN™ Solid Fuel Warm Air Furnace
is designed to provide supplemental or central heating
for your home. This solid fuel furnace may be installed
in conjunction with a central furnace that is in proper
operating condition and meets all national and/or
local building codes, safety standards, required controls
and has been installed in accordance with appropriate
standards of the National Fire Protection Association
and in accordance with the clearances specified on the
furnace nameplate.
Installation of NORSEMAN™ Furnaces must
be accomplished by a qualified heating contractor
(one who is engaged in, and is responsible for, or is
thoroughly familiar with the installation and operation
of gas, oil, and solid fuel burning heating appliances,
who is experienced in such work and 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 in-
stalled to provide clearances to combustible materials
not less than specified in the individual classifications
and marked on the furnace. The chimney must be suit-
able for use with residential type or building heating
appliances which burn solid fuel.
The furnace is designed to operate in ei-
ther parallel air flow arrangement with a central
furnace or as a stand alone central furnace. (See con-
nection option diagrams, figures 17 – 23, on pages
19 – 22.)
CENTRAL FURNACE INSTALLATION
As a central furnace, the unit functions
independently of any other heating system. The
blower(s) will come on when the plenum temperature
reaches the setting on the blower control.
PARALLEL INSTALLATION
When the NORSEMAN™ War m Air Fur-
nace is installed in parallel with an existing cen-
tral heating furnace, it is designed to turn on the
central unit blower whenever the Warm Air Fur-
nace blower turns on. The NORSEMAN™ blower
will only come on when the temperature in the
plenum has reached the setting on the blower
control. This insures there will be sufficient warm air
in the system to provide for efficient operation. When
the central system thermostat calls for heat, the central
system will operate by igniting the burner and turning
on the blower. It is possible that both systems will oper-
ate simultaneously. For the most efficient use of your
NORSEMAN™ Warm Air Furnace, it is recommended
that it be fired as much as possible in order to reduce
the demand on the central heating system. An optional
forced draft kit (Model DK-50) is available that operates
from a wall thermostat. When the temperature falls
below the setting on the wall thermostat, the forced
draft will come on.
T h e w a r m a i r s u p p l y o u t l e t o f t h e
NORSEMAN™ Furnace MUST NOT BE CON-
NECTED TO THE COLD AIR RETURN of the
central heating furnace because of the possibility of
overheating components of the central furnace and
causing it to operate other than it was designed.
Operating external static pressure and air tem-
perature rise of existing furnace must be within ratings
marked on the central furnace nameplate. Test opera-
tion of central furnace after installation of supplementary
furnace.
