Installation

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). (See Fig. 13) If central
air conditioning 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. 11).  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.

g) Optional Plenum Fan Control Switch (Part No.

11PCS) is available for installation on the plenum of
central hot air heating furnace. The purpose of this
switch is to activate the circulating fan of the central hot
air heating furnace when the temperature in the plenum
exceeds 120° Fahrenheit. The switch would activate the
fan at 120° Fahrenheit, and would shut off the circulating
fan when the temperature in the plenum is reduced to
100° Fahrenheit . This avoids overheating the plenum.

The electrical supply for operation of this fan control

switch is to be obtained from same electrical supply as
the central hot air heating system. (See Fig. 13) Follow
the instructions of the  wiring diagram (Fig. 14). Do not
make connections across Limit Control in the furnace.

Make electrical connections in electrical junction

box presently mounted on the furnace. Make electrical
connections in accordance with NFPA Standard No. 70
and local codes in the power supply junction box (See
Fig. 14). The wiring to complete the connections should
be 18 AWG minimum copper and 90° Centigrade in a
cable.
