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:

Unit to Combustible: Front: 48"

Back: 30"

Sides: 12"

Plenum to Ceiling: 2"

Pipe to Combustible:

Sides: 18"

Back: 18"

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.

NOTE: THE MAXIMUM STATIC PRESSURE AT THE CENTRAL OR COMBINED PLENUM MUST NOT
