and one flat washer furnished with insulator assembly).
2. Screw on first half nut firmly.
3. Position first washer.
4. Electric wiring to heating elements must be installed in accor-
dance with National Electrical Code and local electrical codes by a
qualified person.
Electric Shock Hazard. Any installation involving electric
heaters must be effectively grounded in accordance
with the National Electrical Code to eliminate shock
hazard.
5. Connect lead wire.
6. Position second washer.
7. Screw on second half nut tightly.
8. Position insulator skirt allowing slots to slip over leads.
9. Position wave spring on insulator skirt (if needed).
10. Position insulator cap to line up with threaded terminal of heater.
11. Turn cap clockwise until seated firmly on insulator skirt.
Do not exceed 25 inch pounds of torque when tightening the hex nuts on the heater terminals. Excessive
torque will result in stripping the terminals from the
refractory of the heating element. Do not use tool to
tighten cap. Ceramic insulator is fragile and overtightening cap will cause breakage.
Note: If lead wire is too heavy to permit cap to seat firmly, omit washers.
