Furnace Installation

Installing Wood/Coal High Limit Switch-

SF2600 only.

First, install the sheet metal sides as described in the previous section. Install the snap disc switch into the hole on the right side sheet metal. Then mount the open backed junction box around the snap switch. Proceed with wiring as shown on page 10. Also refer to Figure D. in this section.

Mounting The Oil Burner- SF2600 only.

Remove oil burner unit from it’s box. Loosen the four bolts in the pipe on the front of the furnace. Insert the nose of the oil gun into the pipe. Before sliding the oil burner all the way in, apply the gasket around the nose of the oil gun by wrapping it around the nose. Next, slide the oil burner into the pipe and secure it by tightening the four bolts around the collar. Be sure to tighten the bolts evenly to locate the oil burner in the center of the pipe. The final set-up of the oil burner should be done by an experienced oil burner technician with the proper equipment. Refer to the SF2600 wiring diagram on page 10 and the oil burner manual for proper burner set-up. There is also a section at the end of this manual with specific oil burner instructions.

Venting Guidelines.

Your Harman hot-air furnace must be vented to it’s own separate flue-lined “Class A” chimney, not less than 8” X 8” in size. The chimney must be capable of providing a draft reading of at least .06” water column on a draft meter, in order to function properly. The Chimney must be a minimum of 16 ft. high, and must be two feet higher than anything within 10 ft. The chimney must also be at least 3 ft. higher than the point at which it exits or passes by the roof. A barometric damper must be installed in the flue to eliminate excessive draft. Any horizontal sections of connector pipe must have at least 1/4 in. per foot rise. Limit the number of elbows to two or less. All joints in the connector pipe must be secured with sheet metal screws.

Assembly.

Bolt the shaker handle to the block on the lower left side of the furnace, using the bolts and lock-washers provided.

Bolt the two manual draft controls to the front load door. Proper installation allows the draft controls to open approximately 1/2” from the door surface. See Figure 1.

Bolt the automatic draft control to the bottom door. Be sure to hold the unit straight while

tightening. After the automatic draft control is mounted, the two wires must be strung through the flexible conduit and two fittings supplied. The knockout plug of the junction box must be removed to install the conduit fitting. Check the door of

the automatic draft control to assure proper operation. Warning: Keep pieces of wood or coal out of the draft door opening mechanism, as this could cause the door to stick.

NOTE: Oil the hinge at the begining of the heating season with a light oil.

The junction box is best mounted on the side of the furnace about 1 in. back and 8 in. from the top of the sheet metal side. (fig. C or D) If this location is inconvenient, anywhere on the right side will work.
