Honeywell R8184G User Manual

R8184G PROTECTORELAY

OIL PRIMARY

APPLICATION

The TRADELINE intermittent ignition oil primary control operates the oil burner, oil valve (if desired) and the ignition transformer in response to a call for heat from the thermostat. Through a C554 Cad Cell Flame Sensor, the R8184 monitors the burner flame and shuts down the system on ignition failure or on flame failure during the run cycle. A light emitting diode (LED) on the terminal strip lights when the safety switch opens to provide safety shutdown indication. A manual reset button is provided to reset the safety switch after lockout.

For convenience in system maintenance, the safety switch can be manually opened using a lever on the front of the control. Clock thermostats that power the clock through the primary control transformer will lose time during lockout unless backup batteries are installed.

R8184G is component recognized by Underwriters Laboratories Inc. and meets their flammability test requirements for a final enclosure.

LOCATION

1. Mount on a 4 x 4 inch junction box, directly on the main burner, or inside the appliance cabinet. In replacement applications, mount in the same location as the old control.

2. Ensure the operating temperatures are within the ambient temperature range. Ambient temperature ranges are either -40° to 130° F [-40° C to 54° C] or -40° F to 150° F [-40° C to 66° C] (Refer to box label).

MAKE WIRING CONNECTIONS AND MOUNT CONTROL

Wiring must comply with all local codes and ordinances.

Before mounting the control, make line voltage connections as shown in Fig. 1 or 2. Splice leads with solderless connectors. Do not exceed load ratings shown on the device label.

If cad cell leads are run with line voltage wires, breakout knockout at the bottom of the low voltage terminal strip and thread can cell leads through the hole.

If necessary use control as a template to mark and drill new mounting holes. Mount using No. 6 screws (obtain locally).

CHECKOUT

START SYSTEM

WARNING

Fire hazard. Can cause severe burns. Make sure combustion chamber is free of oil or oil vapor before starting system.

1. Push in and release red reset button.

2. Open hand valve in oil supply line.

3. Make sure system is powered. Check circuit breaker or fuse and close system switch, if provided.

4. Set thermostat to call for heat.

5. Burner should light and operate until call for heat ends.

CHECK SAFETY FEATURES

Simulate flame failure:

1. Follow starting procedure to turn on burner.

2. Close hand valve in oil supply line.

3. Safety switch should lock out approximately in safety switch timing indicated on label. Indicator light should come on. Ignition and motor should stop and oil valve should close.

Simulate ignition failure:

1. Follow starting procedure to turn on burner, except do not open oil supply hand valve.

2. Safety switch should lock out in safety switch timing (see label). Indicator light should come on. Ignition and motor should stop and oil valve should close.

Simulate power failure:

1. Follow starting procedure to turn on burner.

2. With burner running, trip circuit breaker or remove fuse to turn off power to the system.

3. Burner should stop.

4. Restore power. Burner should restart.

If system does not operate as described, proceed to

Troubleshooting.

TROUBLESHOOTING AND MAINTENANCE

This control contains no field-serviceable parts. Do not attempt to take it apart. Replace entire control if operation is not as described.

PRELIMINARY STEPS

1. Check wiring connections and power supply. Make sure power is on to the controls, burner motor, and ignition transformer.

2. Make sure limit control is closed.

CHECK OIL PRIMARY RELAY

NOTE: You’ll need an insulated jumper wire with both ends

stripped.

1. Disconnect cad cell leads from F-F terminals.

2. Reset safety switch and set thermostat to call for heat. Burner should start.

3. Within safety switch timing, jumper F-F terminals with insulated jumper wire. Burner should continue to run.

4. After safety switch timing, remove jumper. Burner should shut down in safety switch timing.

5. If operation is not as described, replace oil primary control.
