Leveling an Upflow Unit
When the side return air inlets are used in an upflow ap-
plication, it may be necessary to install leveling bolts on the
bottom of the furnace. Use field-supplied corrosion-resist-
ant 5/16 inch machine bolts (4) and nuts (8), See figure 10.
NOTE - The maximum length of the bolt is 1-1/2 inches.
1 - Lie the furnace on its back and drill a 5/16 inch diame-
ter hole in each corner of the furnace's bottom. See fig-
ure 10 for the correct location of the holes, Drill through
the bottom panel and the bottom flange of the cabinet,
2 - Install one bolt and two nuts into each hole. Screw the
first nut onto a bolt and then insert the bolt into a hole, A
fiat washer may be added between the nut and the bot-
tom of the unit,
3 - Screw another nut onto the bolt on the inside of the fur-
nace base. A flat washer may be added between the
nut and the bottom of the unit,
4 - Adjust the outside nut to the appropriate height and
tighten the inside nut to secure the arrangement,
