APPROVALS
The burner and controls are listed by Underwriters' Laboratories Inc.
Accordingly, the burner bears one of the UL labels indicating periodic
inspection of the production of this equipment.
All ASME tanks are built to the standards of Section IV of the American
Society of Mechanical Engineers code and are stamped with their symbol.
The National Board of Boiler and Pressure Vessel Inspectors papers are
furnished upon request. The NB number and HLW symbol (to the right)
are on the plate located just below cleanout on tank. (May be viewed by
removing cleanout cover on jacket).
The heater and burner rating plates or labels provide valuable information.
When ordering parts or inquiring about a unit, be sure to include all
