DESCRIPTION
The Fireye BurnerPRO is a compact, microprocessor based, primary flame safeguard control system
designed to provide the proper burner sequencing, ignition and continuous flame monitoring for on-
off, multi-stage, or modulating burners used in commercial heating and process equipment firing oil
and gas fuels. The system is designed for use in non-permanent operations that requires burner recy-
cle at least once every 24 hours.
Flame monitoring for the UV version is accomplished by the built in amplifier and compatible UV
scanner. Control functions and timings are factory set via unique micro controller firmware. Through
seven SMART LEDs, the control provides current operating status and lockout information in the
event of a safety shutdown. Refer to the BurnerPRO ordering information section later in this docu-
ment for the various combinations of control functions and timings.
A complete BurnerPRO system includes the BP110/230, flame scanner and wiring base. The Burn-
erPRO performs a safety self-test on every start. If a flame is detected prior to a start or during the
purge cycle, the fuel valves are not energized and the control locks out. The LEDs and alarm termi-
nal is used to annunciate the presence of a lockout condition.
Additional functions of the BurnerPRO include:
•Non-volatile lockout capability
•Proof of fuel valve closure
•Air-flow proving
•A run/check feature allows the operator to stop the program sequence in different
positions (Purge, Ignition, PTFI and MTFI)
•Remote and local Reset
•One second flame failure response time
•Smart LEDs provide on board diagnostic lockout information
•Real-time internal diagnostics for added safety integrity
•Extended temperature operation (-40°C to 60°C) with an over-temp inhibit feature
•High capacity relay contacts


Install the wiring base where the relative humidity never reaches the saturation point. The Burner-
PRO is designed to operate in a maximum 90% relative humidity environment. Do not install the
BurnerPRO where it can be subjected to vibration in excess of 0.5G continuous maximum vibration.
Allow at least one inch clearance (2.5 cm) around control for service and installation.
1. Wiring must comply with all applicable codes, ordinances and regulations.
2. Wiring must comply with NEC Class 1 (Line Voltage) wiring or equivalent regional code.
3. Torque rating on terminal block screws is 4.4 in/lbs to 5.3 in/lbs.
4. Limits and interlocks must be rated to simultaneously carry and break current to the ignition
transformer, pilot valve and main fuel valve(s).
5. Recommended wire routing of lead wires:
a. Do not run high voltage ignition transformer wires in the same conduit with any other
wires.
b. Do not route flame detector lead wires in conduit with line voltage circuits. Use separate
conduit where necessary.
6. Maximum wire lengths:
a.The maximum lead wire length is 200ft. (61 meters) to terminal inputs (Operating limits,
interlocks, valves, etc.).
b. Flame Detector lead wires: see section on flame scanners
c. Remote reset: The maximum length of wire is 500 feet (152 meters) to a normally open
remote reset push-button, but should remain within sight and sound of the burner.
A good grounding system should be provided to minimize the effects of AC quality problems. A
properly designed ground system meeting all the safety requirements will ensure that any AC voltage
quality problems, such as spikes, surges and impulses have a low impedance path to ground. A low
impedance path to ground is required to ensure that large currents involved with any surge voltages
will follow the desired path in preferences to alternative paths, where extensive damage may occur to
equipment.
BEFORE INSTALLING THE BURNERPRO CONTROL
WARNING: Controls require safety limits utilizing isolated mechanical contacts. Electronic
limit switches may cause erratic operation and should be avoided.
CAUTION: Ensure that electric power is turned off. Refer to SN-100 for recommended
grounding techniques. Ensure that wiring base terminal is connected to protective earth.
Be aware that power to some interlocks (operating controls, air flow switches, modulating
circuits, etc.) may be derived from sources other than what is controlling the BurnerPRO.

LED INDICATOR LIGHTS
The BurnerPRO control module has seven (7) LED indicator lights to annunciate the operating sta-
tus of the control, as well as provide the reason for the last lockout condition. The "Open Damper"
and "Close Damper" LEDs provide easy set-up of the modulating motor end switches. Each LED
has a graphic symbol to describe its function (see Table below).
Table 5:
The “SMART” LEDs provide a flame strength display during check mode. In check mode, the status LED is yellow,
the fan LED is blinking and LEDs 2-6 grow up from status forming a bar graph. Each LED lit represents 20% of the
total flame signal. See Table 6, Note 1. (5 LEDs lit is 100%, 2 LEDs is 40%)
FAN Lights when the blower motor is energized (terminal 6) and flashes when the RUN/CHECK switch is in the
“CHECK” position during Minimum, Open, PTFI, and MTFI.
OPEN
DAMPER
Will blink when the modulator motor is being driven to the high fire position. Once the high purge switch
closes, this LED will light constant. The LED provides the status of the purge sequence.
CLOSE
DAMPER
Will blink when the modulator motor is being driven to the low fire position. Once the low fire switch closes,
this LED will light constant. This LED provides the status of the low fire start interlock circuit.
AUTO Will light when the control releases to automatic modulating control.
IGNITION Will blink during Pilot Trial For Ignition (PTFI). Will light constant during Main Trial For Ignition (MTFI).
FLAME Will light whenever flame is detected by the flame scanner.
ALARM In the event of a lockout condition, the Alarm LED is illuminated and the remaining LEDs will light up to indi-
cate the lockout condition. See “Safety Lockout Codes.”

FLAME SCANNERS
INSTALLATION - UV SCANNERS
Where possible, obtain the burner manufacturer’s instructions for mounting the scanner. This infor-
mation is available for most standard burners. The scanner mounting should comply with the follow-
ing general instructions:
1. Position the UV1AL, UV90L or UV5 scanner within 39 inches (1 meter) of the flame to be
monitored. Consult SC-108 bulletin for more information.
2. Select a scanner location that remains within the ambient temperature limits of the UV Scanner.
3. The UVlAL scanner is designed to seal off the sight pipe up to 1 PSI pressure. Higher furnace
pressures must be sealed off. To seal off positive furnace pressure up to 50 PSI for the UV1AL
scanner, install a quartz window coupling (#60-1257). Add cooling air to reduce the scanner
sight pipe temperature.
4. Install the scanner on a standard NPT pipe (UV1AL: 1/2”) 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 (P/N: 60-302). The sight pipe must permit an
unobstructed view of the pilot and/or main flame, and both pilot and main flames must com-
pletely cover the scanner field of view.
5. Smoke or unburned combustion gases absorb ultra-violet energy. On installations with negative
pressure combustion chambers, a small hole drilled in the UV1AL sight pipe assists in keeping
the pipe clean and free from smoke. For positive pressure furnaces, provide clean air to pressur-
ize the sight pipe, if necessary.
6. Two UV Scanners may be installed on the burner if it is necessary to view two areas to obtain
reliable detection of the flame. They must be wired in parallel.
7. To increase scanner sensitivity with UV1AL scanner, a quartz lens permits location of the scan-
ner at twice the normal distance. Use 1/2” x 1 1/2” pipe nipple between UV1AL scanner and the
coupling.
8. Request the assistance of any Fireye field office for recommendations of a proper scanner instal-
lation on a non-standard application.

WIRING - UV SCANNERS
To connect the scanner to the control, the UV1AL scanner is supplied with 36" or 72"
(0.9 m or 1.8 m) of flexible cable. The UV90L is supplied with a terminal block. Use two #18 AWG
conductors to connect the UV90L to the control. The UV5 is supplied with 80” (2m) of flexible
cable (detachable).
If it is necessary to extend the scanner wiring, the following instructions apply:
There is no polarity associated with the scanner wiring, except for the UV5. Scanner wires must be
installed in a separate conduit. The wires from several scanners may be installed in a common con-
duit.
1. Selection of Wire
a. Wiring: For extended scanner wiring up to 500 feet (152 M), and for shorter lengths to reduce
signal loss, use a shielded wire (Belden 8254-RG62 coaxial cable, or equal) for each scanner
wire. The ends of the shielding must be taped and not grounded.
b. Avoid asbestos insulated wire.
c. Multi-conductor cable is not recommended without prior factory approval.
2. High voltage ignition wiring must not be installed in the same conduit with flame detector
wires.
SYSTEM OPERATION
The fixed series timings determine the functional operation of the BurnerPRO control (e.g. purge
timing, trial for ignition timings, etc.) The BurnerPRO offers a single multi-functional button and its
functions are as follows:
RESET
The BurnerPRO control provides two methods of resetting the control in the event of a safety lock-
out: The push button reset and terminal 21 remote reset. Both reset methods can be used to stop the
control in its firing sequence at anytime to force a user/emergency lockout. A reset of the control can
be accomplished by momentarily pressing the reset button or engaging the remote reset terminal.
CHECK MODE
The push button reset switch has an added feature that allows the user to freeze the operational
sequence at certain times (Purge, Ignition, PTFI, and MTFI). This is known as CHECK MODE and
it is designed to aid in set-up, start-up and check-out of the burner and its associated interlocks. This
feature is very useful in pilot aiming and adjustment during commissioning or maintenance.
The check mode rules are:
•If the push button reset is held for at least 3 seconds, the status LED changes from green to yel-
low to signal that the control is in check mode.
•Momentarily pressing the push button reset while in check mode transitions the control into nor-
mal operating sequence, thus disabling check mode.
•The control locks out during Purge, Ignition, or PTFI states if check mode is active longer than
30 minutes
•The control allows check mode in MTFI for 2 minutes. The control automatically cancels check
mode after 2 minutes in MTFI state and resumes normal operation.
•When in check mode during PTFI or MTFI states, the control uses the open, close, auto, igni-
tion, and flame LEDs to annunciate the flame signal strength. Every illuminated LED (starting
with the flame LED) represents a 20% signal strength.

NOTES:
1)Presence of flame at this point results in a lockout.
2)When CAST (terminal 13) is open and POC (terminal 12) is open at this point, control locks out after 10 min-
utes. When CAST is open and POC is closed, control remains in same state indefinitely.
3)Control locks out if FEEDBACK (terminal 8) is not present after 10 minutes.
4)CAP (terminal 14) input is required to proceed. Otherwise, control locks out, after 10 minutes.
5)FEEDBACK (terminal 8) must remain present. Otherwise, control locks out, after 10 minutes.
6)Presence of real flame is mandatory. Otherwise, control locks out. Flame failure results in Post-Purge at
lockout.
7)The control locks out if POC (FVES) cannot be proven closed upon call for heat.
EXPLANATION OF SEQUENCE STATES
1) POWER ON
This is the application of power to the control. It's important that a single phase (110/230 VAC 50/
60 Hz) is applied to the control and the inputs to the control are sourced from the same phase.
2) INITIAL SYSTEM CHECK
During this state, the control undergoes an internal Power-On Self-Test (POST) to verify that the
hardware and software are operating properly. The non-volatile lockout feature forces the control
to move to lockout if the last lockout condition was not cleared prior to power off. The control fur-
ther checks the critical input and output terminals to make sure they are in the proper state. The
control expects the flame to be completely extinguished at this point.
3) PRECONDITIONS FOR BURNER STARTUP
The control verifies that the air-flow switch is in the Normally Closed position via the Combus-
tion Air Switch Test (CAST) input and a verification of the main fuel shutoff valve (POC/FVES)
is performed as well. Flame must not be present at this point. Failure to prove POC or CAST input
will lead to a halt in the state sequence or the control will proceed to lockout.
4) CALL FOR HEAT
The recycle limit (terminal 5) is energized to alert the control to start a burner cycle.
5) PREPARE FOR PURGE CYCLE
The control turns on the combustion blower (terminals 6 & 7).
6) MOVE TO PURGE
The control commands the damper actuator to move to the OPEN (high fire) position. It expects
the actuator to report a successful transition to the OPEN position by energizing the FEEDBACK
input (terminal 8). The control also checks to make sure that the airflow switch is operating by
monitoring the CAP input.
7) PURGE
The control purges the combustion vessel for a period of time (length of purge is based on the
control series installed).
8) MOVE TO IGNITION
Upon successful purging, the control moves to ignition by energizing the MINIMUM output (ter-
minal 10). It expects the actuator to report a successful transition to the MINIMUM (LOW FIRE)
position by energizing the FEEDBACK input (terminal 8). Flame must not be present at this
point.
9) IGNITION
The control energizes the ignition transformer by activating terminal 16. It's critical that the
damper actuator remain at the MINIMUM (LOW FIRE) position during this state. Flame must not
be present at this point.

18

10) PILOT TRIAL(1st safety time)
The control turns on the pilot flame by energizing terminal 17. The MAIN direct output (terminal
18) is also energized for systems that implement direct light-off of the main flame during pilot.
The control doesn't check for flame during this phase as the flame may not be fully established.
11) PILOT TRIAL(1st safety time)
The ignition transformer is turned off. The pilot flame signal is proven during this phase. Failure
to “see” a flame results in a lockout.
12) MAIN TRIAL (2nd safety time)
The main fuel valve (piloted) output (terminal 19) is energized to light-off the main flame. Flame
signal must be present during this phase.
13) MAIN TRIAL (2nd safety time)
The pilot output (terminal 17) is turned off during this phase. Flame signal must remain present.
14) RELEASE TO MODULATION
After successfully establishing flame, the control proceeds to relinquish modulation control to the
boiler management system. Flame signal must remain present. Terminal 20 is energized.
15) MOVE TO SHUTDOWN
Move to shutdown occurs when the load demand has been satisfied and the RECYCLE LIMIT
(terminal 5) is open. This forces the control to close the main fuel valves by de-energizing
MAIN_direct (terminal 18) and MAIN_piloted (terminal 19) outputs. The combustion air blower
remains on for post-purge. Flame afterburn is allowed during this phase
16) SHUTDOWN
The control proceeds to purge the combustion chamber for a period of time (length of post-purge
is based on the control series installed). Then it proceeds to the MINIMUM (low-fire) position
and later to the ECONOMY (closed) position. After successfully completing a post-purge cycle,
the control turns off the combustion air blower. Any flame afterburn is expected to be completed
at the completion of post-purge.
17) LOCKOUT
The control proceeds to a lockout state when it detects an internal or external fault condition. The
reset button and remote reset terminal can be used to exit the lockout state. However, the control
will revert to lockout if the fault condition is not rectified.
