WIRING DIAGRAMS

Models PDP/BDP gas-fired unit heaters

Diagram Selection

Diagrams are provided for both single and three-phase circuits,

and are readily identified in the Selection Table on the following

page. The Selection Table enables easy selection of the correct

wiring diagram after the electrical components of the unit

heater have been determined. The control codes are listed to

aid in locating the correct diagram.

Diagram Interchangeability

The following gas-fired unit heater wiring diagrams are for

either 115-volt, 60-Hertz, single-phase power, or for 230-volt,

60 Hertz, three-phase electrical service.

The 115v/60Hz/1φ diagrams may also be utilized for 230v/60Hz/

1φ by substituting 230-volt components for the 115-volt shown.

The 230v/60 Hz/3φ diagrams may be modified to 460v/60

Hz/3φ by adding a 460v to 230v step down transformer and

wiring the unit as shown in the wiring “inset” on all 3-phase

wiring diagrams.

The 460v/60Hz/3φ diagrams may also be utilized for 575v/60Hz/

3φ by substituting 575-volt components for the 460-volt shown.

NOTE: As indicated in every diagram, all wiring must comply

with the National Electrical Code and all local codes. All

components must agree with their respective power source.

Abbreviations and Symbols

To facilitate interpretation and enable simplification

the abbreviations and symbols have been selected as

recommended by ANSI (American National Standards

Institute) and NEMA (National Electrical Manufacturers

Association) standards.
