OPERATION
The schematic diagrams show all systems in the idle
condition:
• Burner off, no call for heat.
• Pyrostat contacts closed (RA116A).
• "Cold”contactsclosed, “hof’contacts open (RA117A,
RA817A).
• Safety switches closed.
• All relays de-energized.
NORMAL OPERATING SEQUENCE
On a thermostat (or line voltage controller) call for heat,
the ignition, oil valve, and burner motor start. The safety
switch begins heating. Afterthe burner flame is established,
the stack temperature rises and expands the bimetal
detector element. The Pyrostat contacts open (RA116A) or
the "hot” contacts close and the “cold” contacts open
(RA117A, RA817A), de- energizing the safety switch heater.
The ignition circuit de-energizes (RA117A, RA817A only).
When the call for heat is satisfied, the system returns to
the idle condition.
IGNITION FAILURE
Iftheburnerflameis not established within approximately
75 seconds (nominal) of a thermostat (or line voltage
controller) call for heat, the Pyrostat contacts (RA116A) or
“cold” contacts (RA117A, RA817A) remain closed. During
that time, the safety switch is heated. If the burner flame is
not established after 75 seconds (nominal), the system
locks out and cannot be started again until the safety switch
is manually reset.
BURNER FLAME FAILURE DURING THE RUNNING
CYCLE
RA116A
The loss of burner flame reducesthe stacktemperature,
closes the Pyrostat contacts, and energizes the safety
switch. If the burner flame is not re-established within the
75 second (nominal) safety switch timing, the system locks
out and cannot be started again until the safety switch is
manually reset.
RA117A, RA817A
The loss of burner flame reducesthe stacktemperature,
opens the "hot” contacts, and shuts the system down by
de-energizing the 2K burner motor relay. After a one
minute (approximate) scavenging period, the "cold” con
tacts close and energize the safety switch heater. If the
thermostat (or line voltage controller) is still calling for heat,
the Protectorelay control makes one attempt to restart the
system. If the burner flame is not re-established in 75
seconds (nominal), the system locks out and cannot be
started again until the safety switch is manually reset.
POWER FAILURE DURING THE RUNNING CYCLE
A power failure shuts off the ignition and burner motor.
If the thermostat is still calling for heat when power is
restored, the stack temperature must cool and return the
system to the idle position. Once the system returns to the
idle condition, it begins the normal operating sequence.

WARNING
FIRE HAZARD
CAN CAUSE SEVERE BURNS
START THE SYSTEM
1. Ensure the Pyrostat detectors are in step.
2. Push in and release the safety switch reset button.
3. Open the hand valve in the oil supply line.
4. Set the limit control and thermostat to call for heat.
5. Close the line switch. The burner should start.
Ensure the combustion chamber is free of oil or
oil vapor before starting system.
STEP THE PYROSTAT DETECTOR CONTACTS
The detector contacts are actuated by a friction clutch
that is mounted on a rod connected directly to the heatactuated element. Occasionally, this clutch gets "out of
step” after a long period of idleness. To place the clutch and
the contacts “in step,”
1. Remove the cover.
2. Pull the lever forward 1/4 inch (Fig. 8).
3. Slowly release the lever.
4. Replace the cover.
CHECK THE SAFETY FEATURES
Simulate Flame Failure:
1. Follow the starting procedure to turn on the burner.
2. Close the hand valve in the oil supply line.
3. The RA116A locks out after 75 second (nominal)
safety switch timing. The RA117A and RA817A lock out
after one minute (approximate) scavenging period and 75
second (nominal) safety switch timing.
4. Reset the safety switch and open the hand valve in
the oil supply line.
Simulate Ignition Failure:
1. Follow the starting procedure to turn on the burner,
except do not open the oil supply hand valve.
2. Safety switch locks out after 75 second (nominal)
safety switch timing. Ignition and burner motor stops and
oil valve closes.
3. Reset the safety switch and open the hand valve in
the oil supply line.
Simulate Power Failure:
1. Follow the starting procedure to turn on the burner.
2. With the burner running, trip the circuit breaker or
remove the fuse to turn off power to the system. The burner
should stop.
3. Restore power. The burner should restart.
FIG. 8—STEPPING THE PYROSTAT DETECTOR CON
TACTS.
Check the Scavenger Timing:
1. Follow the starting procedure to turn on the burner.
2. With the burner operating normally, open and im
mediately close the line switch. The burner should stop
immediately.
3. After recycle timing (one minute approximately), the
burner should restart automatically.
If the system does not operate as described, proceed to
Troubleshooting.
