Oil Primary Controls
INSTALLATION INSTRUCTIONS
APPLICATION
The intermittent ignition R4184D and R8184G,M,N,P Oil
Primary Controls operate the oil burner, oil valve (if
desired) and the ignition transformer in response to a call
for heat from the thermostat.
The R8184M also provides automatic, nonrecycling control
of cooling systems and low voltage thermostat.
The R8184P provides 15-second valve on delay and
selectable 0-, 2-, 4-, 6-minute blower off delay for hydronic
and warm air systems. Select models have 30-minute
blower off delay timing.
All models use the C554A Cadmium Sulfide (cad cell)
Flame Detector to monitor the burner flame and shut down
the system on ignition failure or on flame failure during the
run cycle. A manual reset button is provided to reset the
safety switch after lockout. Clock thermostats (not
available on R8184P) that power the clock through the
primary control transformer lose time during lockout unless
backup batteries are installed.
All models (except the R8184G1310 and R8184G1328)
are Underwriters Laboratories Inc. component recognized
and meet flammability test requirements for a final
enclosure.
NOTE: R8184P is intended for use on oil burning
appliances that do not require a safety rated
prepurge and postpurge function as defined in
UL 296. The valve on delay and blower off delay
in this control are only intended to help establish
draft and reduce oil after drip-related problems.
INSTALLATION
When Installing this Product…
1. Read these instructions carefully. Failure to follow
instructions can damage the product or cause a
hazardous condition.
2. Check ratings given in the instructions and on the
product to make sure the product is suitable for your
application.
3. Make sure the installer is a trained, experienced
service technician.
4. After completing the installation, use these instructions to check out the product operation.
CAUTION
1. Disconnect the power supply before beginning
installation to prevent electrical shock or
equipment damage.
2. Be sure the combustion chamber is free of oil
or oil vapor before starting the system.
Location
쐃 Mount on a 4 x 4 junction box, directly on the main
burner housing or inside the appliance cabinet. See
Fig. 1.
쐇 Be sure that operating temperatures are between
-40°F and +130°F (-40°C and +54°C). Select
R8184G,P models have a maximum temperature of
150°F (66°C), but must be mounted parallel to the
ground to achieve 150°F (66°C). See Fig. 2.

쐇 Mount the control using no. 8 screws (obtained
locally).
Low Voltage Wiring Connections
After mounting, make low voltage connections to screw
terminals as follows:
• R4184D—connect the cad cell leads to the F-F
terminals. See Fig. 3.
• R8184G—connect the cad cell leads to the F-F
terminals and thermostat leads to the T-T terminals.
See Fig. 4 and 5.
• R8184M—connect the cad cell leads to the F-F
terminals and connect remaining low voltage wiring as
shown in Fig. 6.
NOTE: The Y and G terminals are
to the internal circuitry of the R8184M. The
Y and G terminals are provided to simplify
the connections of the cooling equipment.
• R8184N—connect the cad cell leads to the F1-F
terminals and thermostat leads to the T1-T2 terminals.
See Fig. 7.
• R8184P hydronic hookup. Connect the cad cell leads to
the F-F terminals. See Fig. 8.
• R8184P warm air hookup. Connect the card cell leads
to the F-F terminals and the thermostat leads to the
R-W terminals. See Fig. 9.

CHECKOUT
Start System
WARNING
FIRE OR EXPLOSION HAZARD CAN CAUSE
PROPERTY DAMAGE, SEVERE INJURY OR
DEATH
Be sure the combustion chamber is free of oil or oil
vapor before starting the system.
쐃 Push in and release the red reset button.
쐇 Open the hand valve in the oil supply line.
쐋 Make sure the system is powered. Check the circuit
breaker or fuse and close the system switch, if
provided.
NOTE: If the safety switch has just locked out, the
safety switch may need a minute to cool
down before it can be reset.
쐏 Set thermostat to call for heat.
쐄 Burner should light and operate until a call for heat
ends.
Check Safety Features
Simulate flame failure:
쐃 Follow the starting procedure to turn on the burner.
쐇 Close the hand valve in the oil supply line.
쐋 Safety switch should lock out in safety switch timing
indicated on the label (15, 30 or 45 seconds). Alarm
switch contacts close to initiate alarm on models
with remote dry contacts. Ignition and motor should
stop and oil valve should close.
Push red reset button to reset safety switch.
Simulate ignition failure:
쐃 Follow the starting procedure to turn on the burner,
but do not open the oil supply hand valve.
쐇 Safety switch should lock out in safety switch timing
indicated on the label. Alarm switch contacts close
to initiate alarm on models with remote dry contacts.
Ignition and motor should stop and oil valve should
close.
쐋 Push the red reset button to reset the safety switch.
Simulate power failure:
쐃 Follow the starting procedure to turn on the burner.
쐇 With the burner running, turn off the power to the
system by tripping the circuit breaker or removing
the fuse.
쐋 Burner should stop.
쐏 Restore power. Burner should start.
If system does not operate as described, go to the
TROUBLESHOOTING AND MAINTENANCE section.
TROUBLESHOOTING AND
MAINTENANCE
IMPORTANT
1. Only a trained, experienced service technician
should perform the troubleshooting procedure.
2. This control contains no field-replaceable parts.
Do not attempt to take it apart. Replace the entire
control if operation is not as described.
Preliminary Steps
쐃 Check the wiring connections and power supply.
Make sure power is on to the controls, burner motor
and ignition transformer.
쐇 Make sure the limit control is closed.
Check Oil Primary Relay
NOTE: You will need an insulated jumper wire with both
ends stripped.
쐃 Disconnect cad cell leads from F-F or F1-F
terminals.
쐇 Reset the safety switch and set the thermostat to
call for heat. Burner should start.
쐋 Within the safety switch timing, use insulated wire to
jumper F-F or F1-F2 terminals. Burner should
continue to run.
쐏 After the safety switch timing, remove the jumper.
Burner should shut down in the safety switch timing.
쐄 If the operation is not as described, replace the oil
primary control.
Check Cad Cell
쐃 Disconnect the power at the system switch, circuit
breaker, or fuse.
쐇 Disconnect cad cell leads from F-F or F1-F
terminals.
쐋 Clean the cell face with a soft cloth.
쐏 Make sure the cell is seated securely in the socket.
Be careful not to disturb the socket position.
쐄 Reconnect the cad cell leads to F-F or F1-F
terminals.
쐂 Reset the safety switch, turn on the power and set
the thermostat to call for heat.
쐆 If burner does not operate or if safety switch trips,
replace the cad cell. Order Honeywell part
no. 130367 Cad Cell.
