Please see all methods of Installation in Appendix at the rear of this booklet.
This is a furnace, not a free standing stove. You must
direct heated air from 12" outlet away from the furnace,
or it will not function properly.
1. This installation must be done by a qualified
heating equipment installer.
2. The installation is to be done in compliance with
National Fire Protection Association installation
standards: No. 89M, 90B, 211, 70 (National Electric
Code) and Uniform Mechanical Code 913, 6-4, in the
states where applicable. (Their code offers connecting
smoke pipe connectors into chimney with other fuel
burning appliances.)
3. Rooms large in comparison with size of the
appliances:
a) A Wood Burning Furnace needs air for combus-
tion and circulation to house.
b) Provision must be made to make up this air and
not starve gas or oil furnace of combustion air.
c) Have "Authority Having Jurisdiction"
determine that air is of adequate makeup. (Reference
N.F.P.A. Nos. 30 & 54, Code for Installation of Gas & Oil
Equipment)
4. Have "Authority Having Jurisdiction" to inspect all
chimneys and installations for adequate venting and for
compliance with standard and local codes and regula-
tions regarding installation of wood burning appliances.
5. Installation of Supplemental Heat Application to
Existing Central System. (See Fig. 12 for typical instal-
lation.)
a) Place Wood Burning Furnace so that the
chimney connector will be as short as possible and
avoiding unnecessary sharp turns in the smoke pipe
connector and the installation of devices that would
create excessive resistance to the flow of flue gases.
b) Locate the Wood Burning Furnace as close as
practical to the existing central hot air heating system,
maintaining clearances as stated on the label located on
the side of the furnace.
c) Clearances from combustible materials must
be complied with as stated on the label below the fuel
door:
The installation must be made only on a noncombustible
floor.
d) Install the smoke pipe connector to the chimney
with 26-gauge pipe and elbows (to be purchased sepa-
rately), maintaining the proper clearances for the spe-
cific model. Make sure that the proper clearances as
stated on the label and earlier in this manual are
maintained. Seal the smoke pipe in the chimney with
furnace cement. (The chimney connector shall be se-
curely supported, and joints fastened with sheet metal
screws or rivets.)
e) Install 8" diameter heat pipe to plenum of the
central hot air furnace. Use 26-guage pipe and connec-
tors (to be purchased separately). If central air condi-
tioning is installed in the plenum, install heat pipe above
the air conditioning unit. Secure heat pipe connection
with supports and sheet metal screws.
f) Connect electrical supply in the electrical
junction box that is mounted on the back of the Wood
Burning Furnace. See Wiring Diagram (Fig. 10). Re-
move the cover from electrical junction box. Connect
power supply wires to wires designated, using wire nuts.
The power cord supplied may be used for installation, if
permitted by local codes and regulations. If the power
cord supplied cannot be used, the power supply wiring
must be 90 degrees Centigrade in a metal cable and
should be completed by a qualified installer complying
with NFPA Standard No. 70 and local codes.
