WIRING DIAGRAMSModels PDP/BDP gas-fired unit heaters
Diagram SelectionDiagrams 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 InterchangeabilityThe 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.

Wiring Diagram SelectionA. Field and Submittal Wiring Diagram Selection
Wiring in the field changes little when the brand of the controls furnished on the unit heater changes. Select correct wiring diagrams as follows:
1. Determine unit heater model and size.
2. Select control code number from Table 1.
3. Reference unit heater model in the Page Location Index with control code number and determine correct page number for single-phase or three-phase control. Single-phase wiring diagram page numbers are in the upper left of box and three-phase diagrams are in the lower right of box.
4. Wiring diagrams for unit heater accessories are listed in Table 2. Use the accessory diagrams along with the unit wiring diagrams for complete wiring instructions.
B. Service and Troubleshooting
Because internal or factory wiring may vary depending on controls manufacturer, the wiring diagrams must be selected with the series identity number when servicing or troubleshooting a unit heater control system. Wiring diagrams in this bulletin are for unit heaters manufactured after June 2003 and the series identity number is the 5th thru the 7th digits of the unit heater serial number.
EXAMPLE: Serial No. – 01121010697 has a series identity number of 101.
To select the correct wiring diagram:
1. Determine unit heater model and size from serial plate located on the side of the unit.
2. Determine the control code numbers from box marked Control Code, also on the serial plate.
3. Determine the series identity number of the unit heater, then proceed with Step 3 of Field and Submittal Wiring Diagram Selection.
Example SelectionSelect correct single-phase wiring diagram for a PDP175A Control Code 11, series identity number 101.
Locate the Page Location Index which shows the page numbers for PDP and BDP units with series identity number 101 (see page iii). Select the page number where the column for the PDP175 intersects with the line for control code 11. The correct single phase wiring diagram for this unit is found on page 1 in the upper left portion of box. If the unit also had a summer/winter switch the accessory wiring diagram found on page C-2 as per Table 2, would also be required for complete wiring information.
Two-in-one DiagramsTwo wiring diagrams are furnished for each circuit configuration in this manual. Included are a connection diagram at the left for field installation and circuit schematic at the right to aid in continuity and trouble shooting.
The heavier lines in the connection diagram indicate line voltage; the lighter lines indicate low voltage. Solid lines show pre-wiring performed at the factory; dotted lines inform the installer of connections required to put the heater in operation.
