R4184D; R8184G,M,N,P

Protectorelay

Oil Primary Controls

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 instruc-

tions 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.
