DESCRIPTION
Fireye Series D10-20 Burner Management controls provide ignition and main flame failure protec-
tion for automatically ignited oil and gas burners. In conjunction with limit-operating controls and
interlock devices, it automatically programs with solid state timing logic, the burner/blower motor,
ignition, main fuel valve(s) and firing rate motor. The control cycles automatically when the operat-
ing control closes and also following a power interruption, but must be manually reset following a
safety shutdown.
The start-up programming includes a safe start check on each start. If flame signal (real or simulated)
is detected, the ignition will not be energized and safety lockout will occur. An open damper
prepurge and subsequent proof of the low fire position of the firing rate motor before ignition occurs
at each start up. Terminals are provided for a main fuel valve proof of closure interlock which must
be closed before startup and during the prepurge. An interlock circuit is provided for airflow
switches, fuel pressure switches etc. which must be closed during the prepurge and firing period.
Control type 70D10 will initiate a safety lockout if this circuit opens during the prepurge, ignition or
firing period. Control 70D20 will recycle and initiate a complete restart if this circuit opens during
the prepurge, ignition or firing period.
The control system is designed to deenergize all fuel valves within 4 four seconds following flame
failure. An alarm circuit actuates audible and visual alarms after a safety lockout. Plug-in amplifier
modules permit the selection of Ultraviolet, repetitive self-check Ultraviolet, “AUTOCHECK” infra-
red, or Rectification methods of flame detection. For increased safety and reliability, Fireye 72D1R1-
3 Autocheck infrared amplifiers (using the pulsing flame signal) and 72DUVS-45UV5 Ultraviolet
amplifier scanner (using a scanner shutter) check the function of the flame detecting system for any
component failure during each burner firing cycle. Meter test jacks on each amplifier module provide
flame signal readout with a DC voltmeter.
The solid state programmer is a plug-in module. An optional spark cutoff model is available. A test
switch permits the operator to stop the startup programming before energizing the main fuel valves,
for test purposes.

Inappropriate application of a control could result in an unsafe condition hazardous to life
and property. Selection of a control for a particular application. Inappropriate application of
a control could result in an unsafe condition hazardous to life and property. Selection of a
control for a particular application should be made by a competent professional, such as a
boiler/burner service technician licensed by a state or other government agency.
INSTALLATION
CAUTION: installer must be a trained safety control technician.Verify that electrical power
is disconnected before starting installation. Follow the burner manufacturer’s instructions, if
supplied. Otherwise proceed as follows:
Wiring Base
Mount the control wiring base on the burner or on a panel. The location should be free from exces-
sive vibration and within the specified ambient temperature rating. The base may be mounted in any
angular position. All wiring should comply with applicable electrical codes and be suitable for 75C
min. The terminals in the wiring base are designed to permit a variety of connection methods — wire
loop, eyelet, lug or quick connect. A green grounding terminal is provided for equipment bonding.

Circuit recommendations are provided on page 8. Consult with the factory for assistance with non-
standard applications.
ELECTRICAL RATINGS
VA ratings (not specified as pilot duty) permit the connection of transformers and similar devices
whose inrush current is approximately the same as their running current. VA pilot duty ratings permit
the connection of relays, solenoid valves, lamps, etc. whose total operating load does not exceed 10
times the rating.
Running and locked rotor ratings permit the connection of relays, solenoid valves, lamps, etc. whose
total operating load does not exceed the published rating and whose total inrush current does not
exceed 10 times the rating.
Running and locked rotor ratings are intended for motors. VA and VA pilot duty loads may be added
to a motor load provided the total load does not exceed the published rating.
CAUTION: Published load ratings assume that no contact be required to handle inrush
current more often than once in 15 seconds.The use of control switches, solenoids, relays, etc.
which chatter will lead to premature failure of switches in the Fireye control. Similarly the
contacts cannot be expected to handle short circuit currents without damage. It is important
to run through a test operation (with fuel shut off) following the tripping of a circuit breaker,
a blown fuse or any known instance of chattering.
INSTALLING THE PROGRAMMER AND AMPLIFIER MODULES
To assemble or disassemble a control and its plug-in modules, place the unit on a work bench,
remove the two module retained hold-down screws and lift off the module retainer. The module
retainer cannot be removed if the control is secured onto a wiring base.
Insert the appropriate Amplifier module in the slots at the left side of the unit and gently push the
module into position. Insert the appropriate Programmer module in the slots at the right side of the
unit and gently push the module into position.
Replace the module retainer and tighten the two hold-down screws. The unit cannot be installed on a
wiring base if the module retainer is not in place.
BEFORE INSTALLING THE CONTROL
CAUTION: Make sure that electric power is shut off.
Verify that the supply voltage connected to Terminals Ll, L2 is 120 volts AC nominal. Test the elec-
trical field wiring for short circuits and grounds. The recommended method requires the use of an
ohmmeter set on its lowest resistance scale.
1.
Touch the meter probes together and calibrate it accurately to assure a reliable test.

6

2.
Disconnect the neutral wire (L2) from the control system at the power source. Clip one meter
test lead to the grounded green terminal on the lower right side of the wiring base and with the
other probe touch each other terminal. At no time should the meter read other than infinity.
3.
Reconnect the neutral wire (L2) at the power source. Remove.the test probe from the grounded
terminal and reconnect it to Terminal L2 in the wiring base. With the other probe, touch each
other terminal. It is normal to obtain a resistance reading on the meter at some terminals during
this test as there are resistive loads (coils, transformers, lamps, etc.) connected whose normal
DC resistance may be less than 5 ohms. However, at no time should the test meter read zero
ohms.
4.
If either a ground or a short circuit is detected, it must be eliminated before the control is
plugged into the wiring base and power turned on. Otherwise, the control may be destroyed or
improper operation occur.
INSTALLING THE CONTROL
CAUTION: Make sure that electric power is shut off.
1.
Check the electrical tabs on the bottom of the chassis—if they are bent out of position, reposi-
tion them with your fingers using the angle on the bottom of the red tag shipped with the control
as a guide.
2.
Insert the slots at the bottom of the assembled control in the tabs on the wiring base. Push the
control into position. Insert a screwdriver through the hole in the top of the control and tighten
the retaining screw.
Before testing the control operation on the boiler, close the manual main fuel supply. Failure
to do this may cause injury or property damage.

®
Step: 1.
Close the manual main
Step: 2.
Recheck all limit circuit wiring for proper operation and correct connection.
Step: 3.
Confirm that the automatic main fuel valves are wired to terminal 7.
Step: 4.
Power the control and electrically check the proper sequence of operation according to the
Operation section in this bulletin.
Step: 5.
After assuring yourself that all interlocks and valves are properly wired and that the
sequence of operation is correct, open the manual main shut-off valve and proceed cau-
tiously through the boiler light off process. Check all safety interlocks for proper shut down
of the boiler.
INSTALLATION—UV SCANNERS
Where possible, obtain the Burner Manufacturer's Instructions for mounting the scanner. This infor-
mation is available for most standard burners manufactured. The scanner mounting should comply
with the following General Instructions:
1.
Position the UVI, UV2 scanner within 18 inches of the flame to be monitored, the 45UV5
within 30 inches, closer if possible.
2.
Select a scanner location that will remain within the ambient temperature limits of the UV Scan-
ner. If cooling is required, use an insulating coupling (Fireye #35-69 for UVI, UV2 Scanners,
#35-127-1 for 45UV5) to reduce conducted heat.
3.
The UVI, UV2, 45UV5 Scanners are designed to seal off the sight pipe up to I PSI pressure.
Higher furnace pressures should be sealed off. To seal off positive furnace pressure up to 100
PSI for UVI, UV2 Scanners, install a quartz window coupling (#60-1257). For 45UV5 Scan-
ners, use #60-1199 coupling. Add cooling air to reduce the scanner sight pipe temperature.
4.
Install the scanner on a standard IPS pipe (UVI-
1
/
2
'', UV2-
3
/
8
", 45UV5-1") whose position is
rigidly fixed. If the scanner mounting pipe sights through the refractory, do not extend it more
than halfway through. Swivel flanges are available if desired (#60-302 for UVI, UV2 Scanners,
#60-1664-3 for 45UV5). The sight pipe must permit an unobstructed view of the pilot and/or
main flame, and both pilot and main flames must completely cover the scanner field of view.
5. Caution: The scanner must not sight the ignition spark- directly, or any part of the burner
that can reflect the spark back to the scanner. The scanner must not see a pilot flame that
is too small to reliably ignite the main flame.
6.
Smoke or unburned combustion gases absorb ultraviolet energy. On installations having nega-
tive pressure combustion chambers, a small hole drilled in the UVI, UV2 sight pipe will assist in
keeping the pipe clean and free from smoke. The 45UV5 has a
3
/
8
" plug in the mounting flange
that can be removed. For positive pressure furnaces, provide clean air to pressurize the sight
pipe, if necessary.
7.
Two UVI or UV2 Scanners may be installed on one burner if it is necessary to view two areas to
obtain reliable detection of the flame. They should be wired in parallel. Only one repetitive self-
checking 45UV5-1009 Scanner may be installed on a burner.
8.
To increase scanner sensitivity with UVI, UV2 Scanners, a quartz lens permits location of the
scanner at twice the normal distance. Use

9.
Request the assistance of any Fireye Field Office for recommendations of a proper scanner
installation on a non-standard application.
Since oil and gas flames radiate more ultraviolet energy from the base of the flame than from further
out in the flame, this fact should be taken into consideration when installing the scanner sight pipe.

Wiring—UV Scanners
To connect the scanner to the control, the UVI Scanner is supplied with 36" or 72" of flexible cable.
The UV2 with 36" of flexible cable. The 45UV5-1009 is supplied with four 72" lead wires. Install
them in a suitable length of flexible armor cable and connect it to the control. A conduit connector is
supplied with the scanner. Connect black wires (shutter) to terminals Ll, L2; red wires (UV tube) to
Terminals Sl, S2. If it is necessary to extend the scanner wiring, the following instructions apply:
Scanner wires should be installed in a separate conduit. The wires from several scanners may be
installed in a common conduit.
1. Selection of Wire
— Use #14, 16, or 18 wire with 75°C, 600 volt insulation for up to 100 foot distances (signal
loss approximately 20% at 100 feet).
— For extended scanner wiring up to 500 feet, and for shorter lengths to reduce signal loss, use
a shielded wire (Belden 8254-RG62 coaxial cable, or equal) for each scanner wire of UV I,
UV2 and red wires of 45UV5-1009. The ends of the shielding must be taped and not
grounded.
— Asbestos insulated wire should be avoided.
— Multiconductor cable is not recommended without prior factory approval.
2.
High voltage ignition wiring should not be installed in same conduit with flame detector wires.
INSTALLATION — INFRARED SCANNER TYPE 48PT2
Where possible, obtain the burner manufacturer's instructions for mounting the scanner, otherwise
proceed as follows: A single scanner is used to detect both pilot and main flames. The sight pipe on
which the scanner mounts must be aimed so that the scanner sights a point at the intersection of main
and pilot flames.
Proper scanner positioning must assure the following:
1. Reliable pilot flame signal.
2.
Reliable main flame signal.
3.
A pilot flame too short or in the wrong position to ignite the main flame reliably, must not be
detected.
4.
Scanner must have unobstructed view of flame being monitored.
5.
Flame being monitored must completely cover scanner field of view.
6.
To avoid nuisance shutdowns, it is important to avoid sighting hot refractory and to keep scanner
temperature low (below 125°F).
The maximum UV signal
from a flame is found in
the first one-third of the
visible flame taken from

7.
When the proper position has been established, drill a hole through the furnace wall and install a
4" to 8" length of threaded
1
/2'' black iron pipe on which to mount the 48PT2 scanner.
8. When a satisfactory sighting position has been confirmed by operating tests, the sight tube
should be firmly welded in place.
Wiring
Attach the cable supplied with the scanner to a junction box. Splice the cable wires to a pair of wires
not smaller than #18. Install the complete run in a separate conduit to the control. Continuous con-
duit bonding between scanner and control is mandatory! Scanner may be located up to 100 feet from
control. Do not pass scanner wiring through any junction box containing other wires. Do not run
other wires through scanner conduit. Asbestos insulated wire should be avoided.
Keeping the Scanner Cool
The Firetron Scanner (Temperature Limit 125°F.) should never get too hot to grasp comfortably in
the hand. Keep the scanner cool by one or more of the following methods.
1.
Use 6" to 8" length of pipe between scanner and hot furnace front plate.
2.
Use insulating tube (Part No. 35-69) on the end of the iron pipe.
3.
Force air into sighting tube.
4.
Make sure sighting tube does not extend more than halfway into refractory wall.
5.
Use Fireye Sealing Union (Part No. 60-801) when using method 3 above.

INSTALLATION—69ND1 FLAME ROD
The 69NDI flame rod proves a gas pilot flame and/or main gas flame. It is a “spark plug” type unit
consisting of 1/2ll N.P.T. mount, a KANTHAL flame rod, a glazed porcelain insulating rod holder
and a spark plug connector for making electrical connection. The 69NDI is available in 12", 18" or
24" lengths.
The flame rod may be located to monitor only the gas pilot flame or both the gas pilot and main gas
flames. It is mounted on a
1
/2” N.P.T. coupling. The following instructions should be observed:
1. Keep flame rod as short as possible.
2. Keep flame rod at least 1/2" any refractory.
3. Flame rod should enter the pilot flame from the side so as to safely prove an adequate pilot flame
under all draft conditions.
4. If the flame is nonluminous (air and gas mixed before burning), the electrode tip should extend
at least 1/2" into the flame, but not more than half-way through.
5. If the flame is partly luminous, the electrode tip should extend only to the edge of the flame. It is
not necessary to maintain absolutely uninterrupted contact with the flame.
6. It is preferable to angle the rod downward to minimize the effect of sagging and to prevent it
from coming in contact with any object.
7. An adequate grounding surface for the flame must be provided. The grounding surface in actual
contact with the flame must be at least four times greater than the area of the portion of the flame
rod in contact with the flame. It is essential to adjust the flame rod and ground area ratio to pro-
vide a maximum test meter reading.
Note: Interference from the ignition spark can alter the true test-meter reading by adding to or sub-
tracting from it. This trend sometimes may be reversed by interchanging the primary wires (line volt-
age) to the ignition transformer, and may be made ineffective by the addition of grounded shielding
between the flame rod and ignition spark.
8. Proven types of flame grounding adapters as shown below may be used to provide adequate
grounding surface. High temperature stainless steel should be used to minimize the effect of
metal oxidation. This assembly may be welded directly over the pilot or main burner nozzle.

Start-up
1. With power applied, the limit-operating control circuit closed and the main fuel valve interlock
closed, the burner/blower motor (Terminal M) is energized, the running interlock circuit (air
flow switch) closes. The “Blower” indicator (LED), and “Purge” indicator (LED) lights.
2. The firing rate motor is driven toward the open damper position.
3. Control type 70D10 - when the firing rate motor reaches its open damper position (Highfire), the
open damper interlock closes and initiates the prepurge interval of 30 seconds. If the interlock
does not close, the programming will pause until it closes. Control type 70D20 - a prepurge of
30 seconds is initiated
4. When the prepurge is completed, the “Purge” indicator (LED) goes out, the firing rate motor is
driven toward the low fire position.
5. Following the 30 second delay to permit the firing rate motor to reach the low fire position, a
check is made for the low fire start interlock. If it is not closed, the programming sequence will
pause until it closes.
6. With proven low fire position, the spark ignition and pilot valve are energized (Terminal 5 and
6). The “TFI” indicator (LED) lights.
7. Programmer 71D70 deenergizes the spark ignition after 5 seconds, when connected to Term. 5.
8. When the pilot flame is proven, the “Fireye” indicator (LED) lights.
9. Following a 10 second proven pilot stabilization period, the main fuel valve(s) (Terminal 7) is
energized. The TFI indicator (LED) goes out.
10. With 71D60 programmer, following a 10 second (Terminal 5) or 15 second (Terminal 6) main
flame trial for ignition, the pilot ignition is deenergized. With 71 D70 programmer, following a
10 second main flame trial for ignition, the pilot ignition (Terminal 6) is deenergized. The firing
rate motor is released to automatic control, and the “AUTO” indicator lights.
11. End of supervised start-up program.
Normal Shutdown
1. When the operating control circuit opens, the main fuel valve is deenergized, the firing rate
motor is driven to the closed damper position.
2. Following a 15 second post purge, the burner/blower motor is deenergized.
3. All indicators (LED) go out.

12

Note: If the main fuel valve interlock is not closed at the start, the control will not initiate a start up—
(70D10 will lock out).If it opens during the prepurge—and remains open, the programming sequence
will not proceed. The burner/blower motor will be deenergized in 15 seconds.
Safety Shutdown
1. Control D10. If the running interlock circuit does not close, the control will lock out and the
blower motor will be de-energized. If the interlock circuit opens during a firing period, all fuel
valves will be de-energized and the control will lock out. Control D20. If the running interlock
circuit does not close, the burner/blower motor will continue to run.The start-up programming
sequence will not be initiated. If the interlock circuit opens during a firing period, the burner will
be shut off, and a new start up programming will be initiated.
2. If pilot flame is not detected during the 10 second pilot trial for ignition period, the pilot valve and
ignition transformer will be deenergized and the control will lockout on safety.
3. If main flame is not detected at the end of the main flame trial for ignition period, all fuel valves
will be deenergized and the control will lockout on safety.
4. If the main flame fails during a firing cycle, all fuel valves will be deenergized within 4 seconds
after loss of flame signal and the control will lockout on safety.
5. Manual reset is required following any safety lockout.
Description of Functions of Operating Controls
1. Operating Controls: Generally pressure or temperature activated. Normally, when the operating
control closes, the burner start-up programming starts. When the operating control opens, the
burner shuts off. They are connected between Terminals Ll and 13.Llimit switches: Generally
pressure, water level or temperature activated.
2. Recycle - When it is desired to stop the burner when the limit switch opens and restart it when the
limit switch closes, they are connected between Terminals Ll & 13.

13
®
3. Non-Recycle - With the Dl0 unit, limit switches may be connected in the circuit between Terminals
3 and P. If a limit switch opens during the trial for ignition or firing period, all fuel valves will be
deenergized and the control will lockout on safety. If the limit switch opens momentarily during the
prepurge period and recloses, the purge period will be extended for the amount of time the switch
was open. If the limit switch stays open during the purge period, the control will lockout on safety.

4. Fuel Valve Proof of Closure Interlocks: Usually an integral switch mounted on the main fuel valve
and activated by the valve stem and is connected between Terminal 3 and 13. The valve proof of clo-
sure interlock prevents a burner start-up if the valve stem is not in the valve closed position.
Note: The use of a Fuel Valve End Switch is highly recommended. All D-Series systems have this provi-
sion and when properly connected, the switch will add additional safety to prevent hazardous situations.
5. Purge Interlock: Generally a firing rate motor linkage position switch or a differential air-pressure
switch, that proves a purge air flow rate. It is connected between terminals D & 8 on the D10. The
purge interlock proves that the purge air-flow rate is at maximum during the purge.
6. Running Interlocks: Generally are air flow switches, high and low fuel pressure switches, oil temper-
ature switches, atomizing medium pressure switches, and excess smoke density controls. These
interlocks prove proper conditions for normal operation of the burner. They are wired in series and
connected between Terminals 3 and P.
7. Low Fire Start Interlocks: Generally a firing rate motor linkage position switch or a damper position
switch, that prove the linkage and dampers are in their proper positions for burner light off. They are
connected between Terminals M and D.

USE OF AUXILIARY DEVICE IN M-D-8 CIRCUIT AT 70D10
CONTROL
The function of the low fire start and high fire purge interlock circuits internally in a
new Fireye 70D10 unit is accomplished by highly reliable solid state electronic cir-
cuitry. This prohibits the connection of power consuming devices (i.e. lamps, annun-
ciators, relays, timers, etc.) to the D or 8 terminals. If a need arises for an auxiliary
function such as an extended purge timer, it may be connected as follows:

INSTALLATION TESTING
To test the Series D10-20 controls for flame signal, a 1,000 ohm/volt (or greater) DC voltmeter or a
Digital meter with input impedance of 500K ohms or greater, should be used, set on a scale to read
the following test voltages:
Flame Signal DC Test Voltage
Drop Out Normal
5 volts 20-25 volts
Note: The Fireye 45UV5-1009 is a repetitive self-check scanner that contains a highly reliable shut-
ter that closes every 4 seconds to initiate a system check. When the shutter closes, the test jack volt-
age should go down to approximately zero, and then back to the normal reading in about 2 seconds.
To assure sufficient flame signal margin to hold in the flame relay during random momentary down-
ward fluctuations of flame signal, it is recommended that a signal close to normal be obtained. The
leads from the test meter plug into the red and black test jacks on the amplifier (red + black -).
Normal Pilot Flame Test
Caution:Beforemakingapilotflametest,manuallyshutoffthefuelsupplytothemainburner.
1. Place the “check-run” switch on the programmer in the “check” position. A small tool such as a
screwdriver is required. Turn power on and initiate a normal start-up.
2. Observe the pilot flame signal on the test meter. If the average voltage is below normal, readjust
the pilot flame or realign the detector.
3. During the pilot flame test and adjustment period, if flame is not detected the control will lock-
out. To reestablish the pilot flame trial for ignition (TFI), manual reset of the lock- out switch is
required, and a complete repurge accomplished.
4. When UV flame detection is used, a test is required to verify that UV radiation from the ignition
spark is not being detected. To accomplish this, manually shut off both pilot and main fuels. Ini-
tiate a normal start-up and when the TFI light comes on, observe the test meter which should
read no more than I volt. If more than I volt is observed realign the UV scanner, and/or shield
the spark from the scanner's view. Programmer 71D70 provides for ignition spark cutoff prior to
pilot flame proving when the ignition transformer is connected to Terminal 5 to assist with
installations where UV radiation from spark ignition is difficult to eliminate from the view of
the UV scanner.
5. With all methods of flame detection, check Pilot flame failure response by manually shutting off
the pilot fuel and then initiate a normal start-up. With no Pilot flame present, the control will
deenergize the pilot assembly at the end of the trial for ignition interval, and the control will
lockout. The “check-run” switch must be in the “run” position for this test.
MEASURING TEST JACK VOLTAGE
Main Flame Test (This test requires an interrupted pilot).
1. Proceed through a normal startup. After the pilot flame is shut off, observe the reading on the
test voltmeter. If the voltmeter reading is low, readjust main flame or realign detector.
2. Check main flame failure protection by manually shutting off the main fuel supply. Within 4
seconds after main flame goes out, the fuel valve will be deenergized. The alarm circuit will be
energized following safety lockout.

EXTERNAL METER CONNECTIONS
The test jacks are located on the amplifier card, if external access is desired for a panel meter the
shown below will assist you in locating the position to drill through on the front cover. The hole sizes
should be large enough to accommodate the body of the meta probes. The test jacks accept meter
probes up to .080” or 2mm diameter.
Minimum Pilot Test
This test assures that the flame detector will not detect a pilot flame too small to reliably light off the
main flame. The test should be made on every new installation, and following any repositioning of
the flame detector. This procedure should not be used on a direct spark ignited burner.
CAUTION: The minimum pilot test must be accomplished by a qualified burner technician.
1. Turn off the main fuel supply manually.
2. Place the “check-run” switch in the “check” position.
3. Turn power on and initiate a normal start-up.
4. Reduce the fuel supply to the pilot until the “Fireye” light goes out. (If a test meter is used, the
DC test jack voltage will be below 5 volts.)
5. Slowly increase the fuel to the pilot until the DC test jack voltage reads about 16-20 volts. This
is the minimum pilot flame that the flame detector will reliably detect.
6. Place the “Check-Run” switch in the “Run” position. When the main fuel safety shut-off valve is
energized, slowly open the manual main fuel valve.
7. Observe the light-off of the main flame. It must be smooth and normal.
8. CAUTION: If the main flame does not ignite immediately, shut off the main fuel. Realign
the detector to require a larger minimum pilot flame.
9. Repeat the test until reliable, smooth light-off occurs with the minimum pilot.
10. After this test is completed, increase the fuel to the pilot to its normal setting.

Test for Incandescent Refractory Hold-ln With Photocell Detector
Type 45CM I Photocell Scanners are actuated by light energy. To assure that the flame failure
response time is not extended by radiation from incandescent refractory, the following test is recom-
mended:
1. Operate the burner, following the burner manufacturer's instructions, until the refractory is at
maximum operating temperature.
2. Turn off the main fuel supply manually.
3. Observe the “Fireye” light (LED), which must go out within 4 seconds.
4. If the flame failure response time exceeds 4 seconds, reduce the amount of light at the Photocell
with a screen, an orifice or a filter lens, until the normal flame failure response is obtained.
Operational Test
When the installation and all burner adjustments are completed, the entire burner control system
should be tested in accordance with the burner manufacturer's instructions. The procedure should
verify the correct operation of:
1. Each operating control (temperature, pressure etc.).
2. Each limit switch (temperature, pressure, low water cut- off, etc.).
3. Each interlock switch (air-flow switch, high and low fuel pressure or temperature switches,
purge and low fire start switches, fuel valve proof of closure interlock, etc.).
4. Pilot flame failure response and lockout.
5. Main flame failure response and lockout.
6. Tight shutoff of all fuel valves.
Note: Before attempting to reset the lockout switch, wait approximately 2 minutes for the lockout
switch heater to cool.
SERVICING
Caution: Only trained and qualified Safety Control Technicians should attempt to service
Flame Safeguard Control installations. Special care must be exercised in troubleshooting a
burnercontrolsystem.Electricallylivepartsareexposedwhencoversofdevicesareremoved.
Additionally, safety interlocks and limit switches (air flow, fuel pressure, LWCO, etc.) should
not be jumpered out during troubleshooting, nor should any attempt be made to eliminate
or alter any portion of the programming sequence beyond use of the “Run-check” switch
during the pilot “trial for ignition” period of pilot ignited burners.
Servicing of Fireye D Series units is facilitated by the use of Plug-in Programmer and Amplifier
modules. Trouble with installations equipped with Fireye 70D10, 70D20 Controls can be readily iso-
lated by following the procedure in the sequence listed below. An AC-DC test meter is required. Test
points are located on the chassis board to assist with measuring line and load voltages (150 volt AC
scale).
Before beginning any troubleshooting, make sure that:
1. Installation and wiring have been made in accordance with the installation instructions.
2. Contact tabs on bottom of chassis are not bent out of position.
3. Chassis is properly secured to the wiring base.
4. The programmer is securely plugged in and the “Run- Check” switch is in the “Run” position.
5. The correct amplifier for the method of flame detection desired is securely plugged in
6. The flame detector is clean.
7. The lockout switch is reset.
