Fig. 3—Typical hookup for Tradeline R8184G with indicator light and isolated alarm relay.
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
IMPORTANT
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.
Mount control as shown in Fig. 1 or 2. After mounting,
make low voltage connections to the screw terminals. Strip
leads 3/8 in. [10 mm] and insert under terminal screw. See
Fig. 1 or 2. Connect cad cell leads to F-F terminals and
thermostat leads to T-T terminals. See Fig. 3 or 4.
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.
