2. The installation is to be done in compliance with National Fire Protection Association installation standards: No. 89M, 90B, 211, 70 (National Electrical 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" 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" is to inspect all chimneys and installations for adequate venting and for compliance with standard and local codes and regulations regarding installation of wood burning 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" Pipe to combustible: Sides: 21" 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 separately), maintaining the proper clearances 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 junction 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 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 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 system. Follow the instructions of the wiring diagram (Fig. 11). Do not make connections across Limit Control 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. 12 Figure 12 6" MIN. PLENUM 2" MIN.
