17. Set the heater in place on the steamer with the heat transfer paste in contact
with the steamer bottom. The notch in the heater casting should be towards
the front of the steamer and the heater wires should be towards the electrical
compartment. Try not to get paste on the studs when putting the heater in place.
Center the holes in the casting on the studs.
18. Swing the heater mounting brackets back over the heater.
19. Place the large fender washers over the center studs.
20. Place a spring washer over each stud. Spring washers are conical shaped
washers that flatten out as the nuts are tightened against them. The spring
washers should point up like a miniature volcano. The purpose of the
spring washer is to allow the heater to expand and contract with changes in
temperature.
21. Install new nuts on the studs and hand tighten. Use an inch pound torque
wrench and tighten each nut to 37 inch pounds per the tightening sequence in
FIG 4.4F Do not over-tighten the nuts. Repeat the tightening procedure with the
torque wrench to check that each nut is at 37 inch pounds.
