FLAME SAFEGUARD CONTROLS
WARNING: Selection of this control for a particular application should be made by a competent professional, licensed by a state or other government agency. Inappropriate application
of this product could result in an unsafe condition hazardous to life and property.
DESCRIPTION
The Fireye® M4RT1 Flame Safeguard Control is a compact burner management system. It is
designed to provide automatic ignition and continuous flame monitori ng for commercial sizes of
heating and process burners that use gaseous fuels.
Flame monitoring is accomplished by a Flame Rod detector, the built in amplifier and programmer.
Control functions and timing are factory set with onboard jumpers. Functions such as recycle/nonrecycle, purge timing, and pilot trial for ignition (P.T.F.I.) time are determined by the jumpers. Flame
Failure Response Time (F.F.R.T.) is fixed at three seconds. LED indicator lights indicate the operating status of the control.
In the event of ignition failure, or following a safety shutdo wn, the unit locks out, activating an
alarm circuit. Cycling the power OFF and back on will reset the control. A manual reset option can
be special ordered. Remote reset (via remote pushbutton) is also available as a special order option.
A detailed description of the programmer sequence is found later in this document. Test jacks are
provided to permit flame signal measurement during operation.
The M4RT1 control incorporates a safety checking circuit that is operative on each start. If flame
(real or simulated) is detected prior to a start or during the purge, the fuel valves will not be energized, and the unit will lock out.
All M4RT1 controls do not require a wiring base due to the terminals included on the relay board.
See INST ALLATION OF CONTROL, SCANNERS, AND FLAME DETECTORS (page 2) for temperature and wiring requirements.

INSTALLATION OF CONTROL, SCANNERS, AND FLAME DETECTORS
Wiring Base
Mount the control in an enclosure/burner panel that provides the proper protection fo r the control.
The location should be free from moisture, excessive vibration and within the specified ambient temperature rating. The control may be mounted in any angular position.
All wiring should comply with applicable electrical codes, regulations, and local ordinances. Use
moisture resistant wire suitable for at least 90 degrees C. Circuit recommendations are found on
pages 10 through 11. Consult the factory for assistance with non-standard applications.
WARNING: Installer must be trained and qualified. Follow the burner manufacturer's instructions, if supplied. Otherwise, proceed as follows.
WARNING: Controls require safety limits utilizing isolated mechanical contacts. Solid state
limit switches are not acceptable and should not be used due to their high leakage currents.
WARNING: Remove power from the control before proceeding.
Replaceable Fuse
The M4RT1 is designed with a field replaceable fuse. The fuse is located on the printed circuit
board. The fuse will blow as a result of an overload conditio n on Terminals 3, 4 or 5. To replace the
fuse, remove power from the system. Using a small screwdriver or similar tool, remove th e fuse
from its holder. Install a Fireye replacement fuse (P/N 23-176) or equivalent 8 amp fuse (e.g. Littlefuse 225008P, 8 amp, 125V).
®
WARNING: Turn off the power when installing or removing the control.
INSTALLATION - 69ND1 FLAME ROD
The 69ND1 flame rod proves a gas pilot flame and/or main gas flame. It is a spark plug type unit
consisting of
a spark plug connector for making electrical connections. The 69ND1 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
The following instructions should be observed:
1. Keep flame rod as short as possible.
2. Keep flame rod at least
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 bu rning), the electro de tip should ext end

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 provide a minimum signal reading of 6.0 VDC.
Note: Interference fr om the ignition spark can alter the true signal reading by adding to, or subtracting from it. This trend sometimes may be reversed by interchanging the primary wires (line voltage)
to the ignition transformer . This interfer ence can also be r educed 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 ad equate
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.
WIRING OF FLAME RODS
For proper operation of flame rectification systems, it is necessary to maintain at least 20 megohms
insulating resistance in the flame rectification circuit.
1. The scanner should be wired using metal cable or rigid conduit.
2. High voltage wiring must not be installed in the same conduit with scanner wiring.
Selection of Scanner Wire
1. Use #14, 16, or 18 gauge wire with 90 C, 600 volt insulation for up to 20 feet distance.
2. The type of insulation used with flame rectification is i mportant, since it must protect against
current leakage resistance to ground. Use Belden 8254-RG62 Coaxial Cable (or equal) for runs
greater than 20 feet. Maximum wiring run not to exceed 100 feet.
MAINTENANCE
Type 69ND1 Flame Rod
The flame rod and its insulator should be kept clean by washing routinely with soap and water. Rods
should be routinely replaced as they oxidize.
Flame Signal Strength
Routine observation of the flame signal strength will forewarn any deterioration in the capability of
the flame detector or its application.

RESET
®
In the event of a lockout condition, the M4RT1 can be reset via a minimum one second power interruption to terminal 7.
RESET OPTIONS (Special Order)
1. Optional M4RT1 reset push button. When this optional reset pushbutton is installed, the M4RT1
can be reset by depressing this button for a minimum of one second.
2. Remote reset option. With this option, the M4RT1 is provided with two additional screw termi-
nals. Using those terminals, a remote, dry contact pushbutton switch can be connected. The
maximum wire length is 100 feet (no.18 AWG wire size is recommended).
CAUTION: Remote reset is recommended only on a control solely for proved ignition programming (pilot ignited burner) or a control for use only with appliances in which unburned
fuel cannot accumulate and that is intended for installation in inaccessible locations such as
open-flame, ceiling-suspended gas heaters.
W ARNING: Selection of the Purge time and Recycle / Non-Recycle operation for a particular
application, by changes to the factory default jumpers described below, should only be performed by a competent professional, licensed by a state or other government agency. Inappropriate selection of these safety critical parameters could result in an unsafe condition
hazardous to life and property.
PROGRAMMER JUMPER SETTINGS
The M4RT1 has a series of 8 jumpers that are used to configure the Pu rg e timing, Pilot Trial for Ignition (PTFI) timing, and recycle or non-recycle operation.
Purge Timing
Jumpers JP1 through JP5 are used to select the Purge timing for the M4RT1. The available Purge
timing selections are 5, 7, 30, 60, and 240 seconds and any additive combination of those ti mes.
Selecting two or more Purge timing jumpers will result in a Purge time period equal to the sum of the
jumpers selected. Selection of a Purge time is accomplished by cutting or not installing the associated jumper. The factory set, default Purge time of 5 seconds (JP1 not installed) is always selected.
The Table below lists all available Purge times and how to select those by cutting jumpers JP2
through JP5.

Pilot Trial for Ignition
Jumpers JP6 and JP7 are used by the factory only to select the PTFI for the M4RT1. The available
PTFI timing selections are 5 and 10 seconds. The factory set, default PTFI time is 10 seconds (JP6
installed, JP7 not installed). The PTFI time may only be set by the factory.
Recycle/Non-recycle Operation
Jumper JP8 is used to select either Recycle or Non-Recycle operation of the M4RT1. The factory
set, default is Recycle operation (JP8 installed). To select Non-Recycle operation, cut jumper JP8.
LED INDICATOR LIGHTS
The M4RT1 has 5 LED lights to indicate the operating status of the control. The function of these
lights are:
Opr Ctrl (Operating Control): This LED is lighted whenever input terminal 7 is energized. The
burner system safety interlocks and operating control should be wired in series and connected to the
M4RT1 terminal 7.
Air Flow: This LED is lighted whenever all of these conditions exist:
— Input terminal 7 is energized (operating control and safety interlocks closed).
— Input terminal 6 is energized (proof of airflow switch is closed).
— Output terminal 8 is energized (blower motor).
PTFI: This LED is energized only during the Pilot Trial For Ignition Period.
Flame: This LED is lighted whenever an adequate flame signal is detected between the M4RT1
terminals S1 & S2.
Alarm: This LED is energized whenever a safety lockout occurs. (See APPLICATION AND
FUNCTION section).
NOTE: The M4RT1 is not powered until the user’s operating control is energized.
®
APPLICATION AND FUNCTION
The M4RT1 provides prepurge, ignition and flame safeguard for heating and process gas fired burners. The “recycle” or “non-recycle” operation is determined by the #8 jumper on the top PCB. Purge
timing, as well as trial for ignition timing is also set by the jumpers. See JUMPER SETTINGS on
page 5.
The M4RT1 amplifier circuitry is designed to utilize a flame rod for flame detection. The Flame Failure Response Time (F.F.R.T.) is fixed at 3 seconds.
Pilot Ignited Burners - “Recycle” Operation
With jumper #8 in the “recycle” position, the typical wiring arrangement illustrated on page 10 for
pilot ignited burners provides the following function:
1. With power applied to Terminal 7 (Opr Ctrl LED lighted), the burner motor circu it (Terminal 8)
is energized. The control then waits for the proof of airflow input (Terminal 6) to be energized
2. The Pre-Purge timing starts when terminal 6 is energized.
3. Following the prepurge period (as determined by jumpers #1 through #5), KL-1 closes, ener-
gizing Terminal 3 which powers the pilot gas valve and Terminal 4 which powers the spark ignition. A five or ten sec. (as determined by jumpers #6 or #7) trial for ign ition is initiated (
LED lit).
4. When pilot flame is detected (Flame LED lit), KF-1 closes, energizing Terminal 5 which powers
the main fuel valve, KF-2 opens de-energizing Terminal 4 which shuts off the spark ignition.
5. When the operating control opens its circuit, or if a power failure occurs, the entire system is de-
energized. Power interruptions in the millisecond range do not affect the operation of the control. Power interruptions of longer duration will cause the control to recycle.

6. In the event the pilot flame is not detected by the end of trial for ignition period (PTFI), the pilot
gas valve (Terminal 3) and spark ignition (Terminal 4) are de-energized. A safety shutdown
occurs followed in approximately 30 seconds by a safety lo ckout that de-energizes the blower
motor (Terminal 8) and energizes the lockout alarm circuit (Alarm LED lighted).
7. In the event of a flame failure during a firing period, the pilot and main fuel valves are de-ener-
gized. Following the prepurge period (as determined by jumpers #1 through #5), with proven air
flow (Air Flow LED lit), the pilot gas valve and spark ignition are re-energized and a five or ten
sec. (as determined by jumpers #6 or #7) trial for ignit ion is initiated (PTFI LED lit). If pilot
flame is detected (Flame LED lit), the main fuel valve is energized, the spark igni tion is de-energized. In the event the pilot flame is not detected by the end of trial for ignition period (PTFI),
the pilot gas valve (Terminal 3) and spark ignition (Terminal 4) are de-energized. A safety shutdown occurs followed in approximately 30 seconds by a safety lockout that de-energizes the
blower motor (Terminal 8) and energizes the lockout alarm circuit (Alarm LED lighted).
8. Manual Reset (supply power cycled off/on) is required following any safety lockout.
NOTE: Wait 10 seconds after lockout before restarting the control.
Pilot Ignited Burners - “Non-recycle” Operation
The function of “non-recycle” pilot ignited burners is the same as described for the “recycle” controls, except that the “non-recycle” operation will lock out following any flame failure. “Recycle” or
“non-recycle” operation is determined by the position of jumper #8. See Programmer jumper settings on page 5.
Direct Spark Ignited Burners - “Recycle” Operation
With jumper #8 in the “recycle” position, the typical wiring arrangement illustrated on pages 10 and
11 for direct spark ignited burners provides the following function:
1. With power applied to Terminal 7 (Opr Ctrl LED lighted), the burner motor circuit (Terminal 8)
is energized. The control then waits for the proof of airflow input (Terminal 6) to be energized.
2. The Pre-Purge timing starts when terminal 6 is energized.
3. Following the selected prepurge period (as determined by jumper #1 through #5), KL-1 closes,
energizing T erminal 3 which powers the primary main fuel valve, and Terminal 4 which powers
the spark ignition. A five or ten second (as determined by jumper #6 and #7) trial for igniti on is
initiated (PTFI LED lit).
4. When pilot flame is detected (Flame LED lit), KF-1 closes, energizing Terminal 5 which pow-
ers the secondary main fuel valve, and KF-2 opens, de-energizing Terminal 4 which shuts off
the spark ignition.
5. When the operating control opens its circuit, or if a power failure occurs, the control is de-ener-
gized. Power interruptions in the millisecond range do not affect the operation of the control.
Power interruptions at longer duration will cause the control to recycle.
6. In the event the pilot flame is not detected by the end of trial for ignition period (PTFI), the pilot
gas valve (Terminal 3) and spark ignition (Terminal 4) are de-energized. A safety shutdown
occurs followed in approximately 30 seconds by a safety lo ckout that de-energizes the blower
motor (Terminal 8) and energizes the lockout alarm circuit (Alarm LED lighted).
Direct Spark Ignited Burners - “Non-recycle” Operation
The function of “non-recycle” direct spark ignited burners is the same as described for the “recycle”
controls, except that the “non-recycle” operation will lock out following any flame failure. “Recycle” or “non-recycle” operation is determined by the position of jumper #8. See Programmer Jumper
Settings on page 5.

INSTALLATION TESTING
Use of Test Meter
Testing the Fireye M4RT1 Control requires the use of a test AC-DC multimeter, with a 1,000 ohm/
volt DC rating or greater, or a digital meter with 500K input impedance or greater.
With the test meter on the DC scale, and the test meter leads inserted into the test jacks. A steady DC
voltage reading of 6 to 18 volts should be obtained when the control is detecting flame, and zero
volts when no flame is present.
With the test meter on the AC scale, line and load voltages may be measured at the identified test
points on the chassis.
On the M4RT1 control, a micro-ammeter may be connected in series with the wire to Terminal S2.
Normal flame will produce a meter reading between 4 and 10 micro-amps.

Flame Signal Testing
1. Manually shut off the main fuel valve for a pilot ignited burner, or the secondary fuel valve for a
direct spark ignited burner.
2. Set the test meter on the DC scale and insert the test leads into the test jacks on the amplifier
module. (If the meter reads backwards, reverse the meter leads). Red - Plus, Black - Negative.
3. Initiate a normal startup.
4. When flame is established, the test reading should be normal: a steady DC voltage reading of 6
to 18 volts.
5. Inadequate flame signal may be improved by:
a Assuring that the flame detector and wiring installati ons have followed the instructions on
pages 3 and 4.
b Assuring that the flame detector is clean and within the ambient temperature limits.
c Assuring that the flame is sufficiently large to detect.
d Assuring that the flame quality (fuel to air ratio, combustion air velocity) is satisfactory.

Minimum Pilot Test
This test insures that the flame detector will not sense a pilot flame too small to l ight th e main fl ame
reliably. It must be made on every new installation as well as following the repositioning of the flame
detector. This procedure should not be used on a direct spark ignited burner.
1. Manually shut off the fuel to the main burner.
2. Connect a test meter to the test jacks.
3. Initiate a normal startup.
4. Reduce the fuel to the pilot until the DC voltmeter reads approximately 6 volts or when the pilot
is at the minimum to provide a reliable main flame light-off. See WARNING below. This is the
minimum pilot.
5. Slowly turn on the main fuel and insure that the main flame lights off promptly and normally.
WARNING: If light off is delayed, shut off the power to the installation. Realign the flame
detector so that pilot flame detection requires a larger pilot flame. Repeat this test until the
main flame lights reliably with minimum pilot.
W ARNING: The minimum pilot test must be accomplished by a trained and qualified burner
technician.
6. After the minimum pilot test is completed satisfactorily, increase the pilot flame to normal size,
and observe that the main flame is properly established during a normal cycle ("Run-Check"
switch in the "Run" position).
Flame Failure Test
1. T emporarily connect spark ignition and pilot valve to Terminal #3.
2. Initiate a normal startup.
3. Manually shut off all fuel and observe the loss of flame signal on the test meter.
4. If flame signal does not reduce to zero within the flame failure response time of the control, a
grounded metallic shield may need to be inserted between the flame ro d and spark ignition to
prevent interference.
5. IMPORTANT: When the test is completed, reconnect the spark ignition to Terminal #4.
