INSTRUCTIONS FOR ORDERING PARTS
All parts orders must show heater Model No., Item No., Part
No., and Description. We recommend that only parts sup-
plied by the manufacturer be used on this unit. A locally
purchased part may appear to be identical, although in real-
ity it might endanger the heater or the persons operating the
heater.
The heater should be serviced only by a trained,
experienced service person.
Read the section on “Servicing” before ordering
parts.
For parts order, call [phone].
