Furnace Installation

To ensure a safe installation, it is recommended that this furnace be installed by a qualified installer.

The sheet metal top and sides can be easily removed to reduce the chance of dents or scratches on the painted surfaces.

To remove the sheet metal, first lift off the top section. Now, the sides can be removed by lifting up and out away from the furnace.

To lighten the SF2600, the oil burner heat exchanger should be removed. Do so by first removing the sheet metal as described above. Remove the front sheet metal by first removing the burner collar. Now remove the the two long bolts on each side of the heat exchanger. (Figure B) The entire unit can now be lifted off and moved separately.

Caution: This furnace must not be installed closer than 24 inches at the sides and 30 inches from the rear to combustible materials. The unit may

only be installed on a non-combustible floor surface such as concrete floor or concrete pad on dirt floor. The hot air plenum must be a minimum of 2 inches from the ceiling or other combustibles above the plenum.

Locate the furnace as close to the chimney as possible while still maintaining the above clearances. No more than 8 feet of stovepipe should be used, including two or less 90° elbows. All horizontal runs of pipe should have a minimum 1/4 in. rise per foot. All stove pipe must be 24 gauge or thicker.

When re-installing the heat exchanger, inspect the gasket around the furnace opening, and replace if necessary. (Figure A) Place the heat exchanger in position and secure with the long bolts and nuts. Be sure the gasket is compressed evenly.

Re-install the sheet metal by sliding the groove on the bottom of each side panel over the steel lip on the furnace. The top sheet metal piece holds the sides in place. The SF2600 front cover gets installed by angling the bottom edge over the lip on the top of the firebox. The side edges must slide into the grooves on each side and pushed in flush with the sides and top. This front piece is held in place by the black ring which gets tightened around the burner pipe. Do not over tighten as this will push the sheet metal in too far.

Inspect Gasket prior to re- installing heat exchanger.
