1. All electrical work must conform to Local and National Electrical Codes. This unit must be connected to a separate 15 amp maximum branch circuit. The minimum wire size allowable is No. 14AWG Copper. NOTE: The use of UL Listed connectors of the proper size is required.

2. The duplex receptacle may be installed in either the left or right wiring compartment. Remove the desired wiring compartment cover and discard.

3. Drill hole through floor or wall at knockout location where branch circuit supply will enter the wiring compartment. (This may require removing the heater).

4. Feed branch circuit supply wire through drilled hole and knockout in heater. Install cable connector (not supplied).

5. Connect branch circuit supply to duplex receptacle as shown in wiring diagram, (Figure 3).

6. Reconnect power at main fuse or circuit breaker distribution panel for the heater and duplex receptacle.

INSTALLATION

1. All electrical work must conform to Local and National Electrical Codes. The use of UL Listed connectors of the proper size is required. Supply wiring must be suitable for 90° C.

2. Remove the control box cover where the power supply leads are. Remove small knockout in back of baseboard and make aligning hole in wall (See Figures 6 and 7). Fish thermostat wires through this hole.

3. Loosely install both transfer relay screws. Attach baseplate as shown in Figures 6 or 7.

4. Slide transformer/relay under loosely installed screws in base plate and tighten screws. NOTE: For left end installation transformer/relay is mounted upside down.

5. Push the red and white transformer wires through the hole in the top of the baseplate. Make 24V thermostat connections in the compartment formed by the baseplate and the top of the wiring compartment. (See wiring diagram Figure 4).

6. For right end connection remove wire nut and connect power supply wire (L2) to the larger yellow wire and to the element lead wire. Connect power supply wire (L1) to larger black wire and connect blue wire to return wire. (See wiring diagram Figure 4).

CHECK OPERATION

1. Before connecting power supply, be sure all thermostats are turned to “LOW” or “NO HEAT”.

2. Connect power supply at distribution box. Wait 3 to 5 minutes and check to see that none of the heaters are operating. Should any of the heaters be operating, disconnect power supply and check wiring.

3. If none are operating, turn the thermostats to the highest position and wait 3 to 5 minutes. Check to see that all heaters are operating. If any are not operating, disconnect power supply and check wiring.

PR24C and PR120C

1. All electrical work must conform to Local and National Electrical Codes. The use of UL Listed connectors of proper size is required.

2. On PR24 model, using 24 volt class 2 control circuit wiring, remove small knockout in back of baseboard and make aligning hole in wall (See Figures 8 or 9). Route 24 volt class 2 external control circuit wires through this hole. On PR120 model, the control circuit wiring connections may be made in the heater wiring compartment.

3. Attach baseplate to back of wiring compartment with screws provided. (See Figure 8 or 9). Insert snap bushing in appropriate hole in baseplate top.

4. Mount power relay on baseplate and securely fasten with screw provided. See Figure 8 or 9 for proper mounting location on baseplate.

5. On PR24 model, using 24 volt class 2 control circuit wiring, push the two red relay wires up through the hole in the top of the baseplate. Make all external 24 volt class 2 control circuit wiring connections in the compartment formed by the baseplate and the top of the wiring compartment. On the PR120 model, connect external 120 volt control circuit wiring in the heater wiring compartment by connecting to the red control wire. The compartment formed by the base plate and top of the heater wiring compartment is not used on the PR120 Model.

6. For right end connection, remove wire nut and connect return wire to one black lead on power relay. Connect power supply wire (L1) to other black lead on power relay. Connect power supply wire (L2 or N) to element lead wire. (See wiring diagram, Figure 5A).

7. For left end connection, remove wire nut connecting the limit control and connect limit control wire to one black lead on power relay. Connect power supply wire (L1) to other black lead on power relay. Connect power supply (L2 or N) to crossover wire. (See wiring diagram, Figure 5B).

8. If more heaters are to be connected to same power relay, refer to wiring diagram Figure 5C. Do not exceed ampacity rating of power relay.

FSJ2 and FS

The FS Filler Sections provide for a uniform appearance by covering open space between heaters or between the end of a heater and the wall. If heaters are butted together, Marley Model Number FSJ2 Joiner Strip should be used. These instructions are provided to assist you in the installation and prevent unnecessary problems that you may encounter. Read and study these instructions as well as the instructions provided with the heaters before installing.

CAUTION

To prevent possible damage to internal wiring, prior to installing the filler section, remove the heater junction box cover(s) at the end of the heater(s) where the filler is to be installed. Position all wiring in the junction boxes so it is not in the area where the self-tapping screw (Step 4) will be installed.

1. Mount the heaters on the wall in accordance with the heater installation instructions. Make sure the heaters are at the same mounting height from the floor to assure a level mounting of the filler section.

2. Position the filler section on top of the heater(s) and press down toward the bottom of the filler to assure a tight fit. The section will snap into place. Do not mount over the junction box screw.

3. If the filler section is to be mounted between a heater and a wall, a block of wood to support one end of the filler should be attached to the wall, level with the top of the heater.

4. Attach filler sections with sheet metal screw, supplied by others, in the bottom of the filler and into the baseboard.
