NOTE: Your furnace may come partially
Prior to assembling, place the unit in the general vicinity of the installation. This should help minimize handling damage to the unit after assembly. Note: If your basement can't handle a height of 7' 8" you must lay the furnace on two, 2 x 4's to slide shrouds onto weldment. Then stand furnace up.
1.Unit side shrouds can be assemble by slipping the side shrouds into place from the top down. If they don't slide easily, open up the lip of the sides with a large screw driver then add a little oil. Sometimes a slight tapping with a block of wood and hammer may be re- quired, but do not force. When properly installed, the electrical
NOTE: The furnace is partially prewired all that is re- quired is the wiring of the distribution fan (see wiring diagram, page 18) and the wiring to wall the thermo- stat.

2.Attaching the distribution fan. First, remove the four
(4) bolts from the rear of the unit. Secondly, slide the distribution fan up to the rear of the furnace, line up the (4) holes and reattach the bolts and tighten se- curely.
3.Attach the draft fan to the back of the weld on the throat (2" throat hole with 3 mounting holes). It's best to use the self tapping screws without the draft fan to establish threads then mount blower. The electrical box on the blower should be facing downward. Draft fan air intake cover should be set at a 20% opening, about 1/2" opening.

4.After mounting the two (2) fans proceed to the fan control center.
NOTE: The best maintenance for fan motors is to keep them clean (exceptionally clean). Oiling with 20W N. detergent once a season will also help, but cleanliness is what prolongs motors life. (Two (2) drops on the draft blade, four (4) drops in the distribution fan.)
