INSTALLATION
Please see all methods of Installation in
Appendix at the rear of this booklet.
Pipe to combustible:
Sides: 21"
Back: 18"
The installation must be made only on a non-
combustible floor.
d) Install the smoke pipe connector to the chim-
ney with 26-gauge pipe and elbows (to be pur-
chased separately), maintaining the proper clear-
ances for the specific model. Seal the smoke pipe
in the chimney with furnace cement. (The chimney
connector shall be securely 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-gauge pipe and
connectors (to be purchased separately). (See Fig.
15) 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 junc-
tion box that is mounted on the back of the Furnace.
See Wiring Diagram (Fig. 11). Remove the cover
from electrical junction box and connect power
supply wires to wires designated, using wire nuts.
The power cord supplied may be used for installa-
tion, 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 degrees F., and shut off the
fan when the temperature in the plenum is reduced
to 100 degrees F. This avoids overheating the
plenum.
The electrical supply for operation of this fan
control switch is to be obtained from the same
electrical supply as the central hot air heating sys-
tem. Follow the instructions of the wiring diagram
(Fig. 11). Do not make connections across the
thermodisc in the furnace.
Make electrical wire connections in accordance
with NFPA Standard No. 70 and local codes in the
power supply junction box (See Fig. 13). The wiring
to complete the connections should be 18 AWG
minimum copper and 90 degrees centigrade in a
cable.
This is a furnace, not a free standing stove.
You must direct heated air from 8" outlets 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 Elec-
trical 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
appliance:
a) Wood or Coal Burning Furnace needs air for
combustion 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" de-
termine that air is of adequate makeup. (Refer-
ence N.F.P.A. Nos. 30&54, Code for Installation
of Gas & Oil Equipment).
4. Have "Authority Having Jurisdiction" is to inspect
all chimneys and installations for adequate venting
and for compliance with standard and local codes
and regulations regarding installation of wood burn-
ing appliances.
5. Installation for Supplemental Heat Application to
Existing Central System. (See Fig. 2 for typical
installation.)
a) Place Wood or Coal Burning Furnace so that
the chimney connector will be as short as practical
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 or Coal Burning Furnace as
close as practical to the existing central hot air
heating system, maintaining clearances as stated
on the label on the fuel door.
c) Clearance from combustible materials must
comply with those stated on the label on the fire
door:
Unit to combustible:
Front: 48"
Back: 30"
Sides: 12"
Plenum to Ceiling: 6"
