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 thermo-  
stat. Through a C554 Cad Cell Flame Sensor, the R8184  
monitors the burner flame and shuts down the system on  
ignitionfailureoronflamefailureduringtheruncycle.Alight  
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.

INSTALLATION  
[
WHEN INSTALLING THIS PRODUCT…  
1. Read these instructions carefully. Failure to follow  
LOCATION  
them could damage the product or cause a hazardous  
condition.  
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 am-  
bient 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).  
2. Check the ratings given in the instructions and on the  
product to make sure the product is suitable for your  
application.  
3. Installer must be a trained, experienced service tech-  
nician.  
4. After installation is complete, check out product op-  
MAKEWIRINGCONNECTIONSANDMOUNTCONTROL  
Wiring must comply with all local codes and ordinances.  
Before mounting the control, make line voltage connec-  
tions 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.  
eration as provided in these instructions.  
CAUTION  
1
. Disconnect power before beginning installation to  
prevent electrical shock or equipment damage.  
. Make sure combustion chamber is free of oil or  
vapor before starting system.

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

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.  
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.

Troubleshooting.  
WARNING  
Can cause severe burns.  
Make sure combustion chamber is free of oil or oil  
vapor before starting system.  
. Push in and release red reset button.  
. Open hand valve in oil supply line.  
. Make sure system is powered. Check circuit  
breaker or fuse and close system switch, if  
provided.  
. Set thermostat to call for heat.  
. Burner should light and operate until call for  
heat ends.
