Oil Fired EDS 3.5 Installation, Operation & Service

Notes
1. Before attempting to recycle unit after a nuisance shut
down: On flame failure or expiration of trial ignition,
electrical supply power to burner must be interrupted
for 5 minutes to allow safety switch to reset. Power can
be interrupted at burner service switch or at the
thermostat. Do not reset control more than 2 times as
accumulation of oil in the combustion chamber can and
will occur. Contact service personnel for assistance.
2. Do not attempt to field repair control components. It is
recommended defective components be replaced as
factory replacement units.
A. PRELIMINARY REQUIREMENTS PRIOR TO
STARTING SYSTEM
1. The system must be installed in compliance with
clearances to combustibles (see pages 4 - 6). Units
installed in public garages should be in accordance
with the ANSI/NFPA 88A-current standard for USA and
CAN 1-B149 .or .2 for Canada. Units installed in
aircraft hangars should be in accordance with
ANSI/NFPA 409-current standard for USA and
enforcing authority for Canada. All reflectors should be
in position and installed according to the installation
instructions and Start Up section tube system of this
manual.
2. Make sure all supply piping has been purged clean.
NOTE: Maximum oil supply to burner assemblies shall
not exceed 3 PSI.
3. The electrical system must be installed according to
local codes and the wire must be adequately sized for
the installation in accordance with the Electrical Wiring
Specification in the Installation Instructions and Start-
Up section of this manual. See that the fan is correctly
wired so the exhauster is running in the correct
direction and that none of the equipment is pulling
more than the specified capacities stated in the
Electrical Wiring section mentioned above.
4. Adjustment of the damper on system is required so
that proper air flow for each burner is obtained.
B. TO START SYSTEM
1. Check to insure that oil supply system is in operation.
2. Check all burners to insure that fusible oil valves at
each burner are open.
3. Turn the main power switch to ON and check fuses.
4. Set the thermostat higher than the existing
temperature of the area to be heated. The following
steps should then take place automatically:
The vacuum exhauster is powered and will start. The
vacuum created by the exhauster pulls in the burner
air flow switch and supplies power to the ignition
control, opening the oil solenoid and generating spark
for ignition. The spark will ignite the oil.
5. Check all burners to see that they are operating.
Flame should be visible through the view window.
6. Set the thermostat down to the desired temperature.
7. When the system is initially fired, any oil that is on the
pipe work and fittings will burn off and form a light
haze in the building which can best be removed by
ventilation system in the building, or opening doors.
This is a one time problem and will not recur.
8. Burner tube may have a faint red glow in a darkened
room (950°F approx.).
9. On start-up there will be condensation in system for
approximately 2 minutes as fan discharge
temperature gets above the condensation point. The
condensation will be dried up in the pipe and
discharged through the fan. This results in a slight
spitting of this moisture out of the fan discharge for
approximately 4 minutes from initial start-up.
C. RESETTING THE FLAME SAFETY CONTROL
The Reflect-O-Ray
®
Oil Fired EDS3.5 burner system is
equipped with an automatic lockout control which is
activated after 5 seconds if the burner should fail to ignite.
If your burner should lock out, it should be reset by the
follow method:
1. Make sure that the vacuum exhauster is operating.
The reset button on the back of the ignition control will
be lit (red LED lamp/button) signifying lockout.
2. Wait five minutes. Press the reset button and the
ignition sequence will start. Ignition should occur. Do
not reset the burner more than two times.
3. The system will now automatically recycle on the
thermostat to maintain desired room temperature.
IF THE BURNER WILL NOT LIGHT AFTER TWO RESET
TRIALS, CONTACT YOUR INSTALLER FOR SERVICE.
D. STOPPING THE SYSTEM FOR SERVICE
1. For servicing an individual burner or exhauster, turn
off the service toggle switch that should be mounted
within two feet of the unit. Close the oil supply valves
at the burner assembly.
2.
To service the thermostat, turn off the electrical power
at the main power disconnect box.
3.
Before servicing any fuel oil component; shut off the
oil supply and remove all electrical power.
CHECK SAFETY SHUTDOWN PERFORMANCE
NOTE: Read steps 1-7 below before starting safety
shutdown or safety lockout tests for the direct ignition (DI)
module.
1. Turn fuel oil supply off at the burner.
2. Set the thermostat or controller above room
temperature to call for heat.
3. Watch for ignition spark immediately or following pre-
purge.
4. Time length of ignition operation.
5. After the module locks out, open fuel oil valve.
6. Set the thermostat below room temperature and wait
five minutes.
7.
Set thermostat above room temperature. Reset the
burner by pushing the button on the back of the oil
burner. Operate system through one complete cycle to
ensure all controls operate properly.
