CHAPTER 1
INTRODUCTION
A. GENERAL INFORMATION
CB Prore S1/Series burners are assembled, wired and
tested at the factory. They are listed by the Underwriters Laboratory, CSD-1, NFPA-85, I.R.I., F.M., including the National Electrical Code (NEC) and associated insurance underwriters. Where applicable, the Canadian Gas As­sociation (CGA) B149 and Canadian Standards Association (CSA) B140 codes shall prevail. Other regulatory agency control options are available.
CAUTION
ONLY FACTORY AUTHORIZED BURNER SERVICE PERSONNEL SHOULD START-UP, ADJUST, OR SERVICE THIS EQUIPMENT
The operator must be familiar with the individual functioning of all controls to understand the operations and procedures described in the manual. Identify and locate each item in the illustrations as they are described in the following sections.
B. DESCRIPTION
The CB Prore S1/Series oil burners are of the low
pressure, air atomizing (nozzle) type. Gas burners are of the peripheral mix type. All burners feature ignition by
spark-ignited gas pilot ame. With either fuel, the burner
operates with full modulation. A switch permits changeover
from automatic fully modulated ring to manually set ring
at any desired rate between minimum and maximum. Ad­ditional safeguards assure that the burner always returns
to minimum ring position for ignition.
S1/Series burners are designed for automatic, unattended operation except for periodic inspection and maintenance. After selecting the proper overload settings for the starter, the rest of the control panel components require little at­tention except for occasional cleaning.
C. OPERATING CONTROLS The burner is supplied with a remote control panel and
with a burner mounted junction box.
CONTROL PANEL
The control panel contains a ame safeguard program-
ming control, motor starters, relays, time delays and termi­nal strips mounted internally on a panel sub-base. Lights,
switches, potentiometers, a control circuit breaker and ame
safeguard displays are mounted externally on the panel as indicated below.
1. ON-OFF BURNER SWITCH - (for gas or oil only)
2. FUEL SELECTOR SWITCH - Gas-Off-Oil (for combination gas-oil burners only)
Gas position: Selects gas as the ring fuel .
NOTE
WHEN CHANGING FROM OIL TO GAS FUEL, ALLOW PROGRAMMER TO COMPLETE POST PURGE AND SHUTDOWN BEFORE MOVING SELECTOR SWITCH TO GAS PO­SITION. THIS WILL ALLOW THE INTERLOCK CIRCUIT TO OIL-AIR PUMP OR COMPRES­SOR TO DE-ENERGIZE
Off position: Burner off.
Oil position: Selects oil as the ring fuel.
3. CONTROL CIRCUIT BREAKER - supplementary low overcurrent protection only. No larger than 15 amps.

The ame safeguard programmer incorporates a ame
sensing cell (scanner) to shut down the burner in the event
of pilot ame or main ame failure. Other safety controls
shut down the burner based on sequence of operation as
shown in the manufacturers ame safeguard manual.
E. COMBUSTION AIR HANDLING SYSTEM
The combustion air handling system consists of two major
components:
1. DAMPER ASSEMBLY. A multi blade system regulates the combustion air volume and is positioned by a modulating motor. The dampers are
normally ALMOST CLOSED in the low-re position and opens as the burner drives toward a high-re position.
2. MOTOR DRIVEN IMPELLER. The diameter of the impeller determines available air pres­sure and the width determines air capacity in cubic feet per minute. Alternate motor-impeller combinations are available
for 50 cycle or 60 cycle power and for ring against either
moderate or high furnace pressure. For higher altitudes and higher furnace pressures, motor and impeller combinations are determined at the factory.
F. FIRING RATE CONTROLS
Regardless of the fuel used, burner input is fully modulated
between low re and high re on boiler demand. Firing rate
is controlled by the potentiometer-regulated modulating motor. Combustion air control damper, oil metering valve
and/or gas volume buttery valves are through variable
rate rod and lever linkages. The modulating motor rotates 90 degrees from low to high position. Flow rate through each component is adjusted by position­ing the control rods on the levers and the angular position of levers on shafts. Lever on the modulating motor shafts
actuate the high re position proving switch.
G. FIRING HEAD
Access to the ring head is provided by swinging open
the impeller housing. First, disconnect the damper linkage,
Figure 1-1
Sec1:4
Figure 1-2
release the housing latch and swing the housing to open position. An internal gas pilot is standard on all burners. Pilot gas pressure is adjusted at the pilot pressure regula­tor.
H. OIL SYSTEM AIR ATOMIZING
S1 Model burners use compressed air for atomization. Atomizing air is independent of combustion air. The system is supplied with a separate compressor module for mount­ing near the burner.
3-WAY SOLENOID VALVE.
Metered oil enters the common port of the 3-way solenoid valve. During shutdown, pre and post purge the valve is de-energized (N.C. port closed) and all metered fuel oil returns to the storage tank. When the valve is energized, metered oil is directed to the nozzle through the normally closed port.
NOZZLE ASSEMBLY.
The nozzle assembly consists of four main parts: body, compression spring, swirler, and tip. The swirler is held against the nozzle tip by the compression spring. The nozzle body has inlet ports for air and oil lines. Metered
fuel oil enters the nozzle body and ows through a tube to
the swirler. Oil is forced from the core of the swirler to the side ports where it meets with the atomizing air. Atomizing air enters and passes through the nozzle body to grooves in the swirler, where it mixes with fuel oil. Air/oil passes
through grooves and out of the nozzle orice in a cone of atomized oil. Proper velocity and angle of the ne spray
ensures good mixing with the combustion air, providing
quiet starts and excellent combustion efciency.

ATOMIZING AIR PROVING SWITCH
Pressure actuated switch contacts close when sufcient
atomizing air pressure is present.The oil valve will not open unless switch contacts are closed.
SEPARATE COMPRESSOR MODULE
All burners have a burner mounted oil metering unit and a separate compressor module. The system functions as follows:
AIR COMPRESSOR MODULE
Air is supplied by a positive displacement rotary vane compressor. This provides a constant volume of atom­izing air regardless of pressure. The compressor module
includes motor, air/oil reservoir tank, air lter and lube oil cooling coil. Air enters the compressor through the lter. The air ows from the compressor into the air-oil separating and reservoir tank. Filtering material and bafes separate
the lube oil from the compressed air. The tank air pres­sure forces lubricating oil from the tank to the compressor to lubricate bearings and vanes. A sight glass indicates the level of lubricating oil in the air/oil reservoir. Lubricat­ing oil must be visible in the gauge glass at all times. Air
compression heat is absorbed in part by the ow of lube
oil, creating a hot oil mist. The air/oil mist is cooled by a coil assembly. Lube oil is also cooled before entering the compressor.
OIL METERING
The oil metering unit is a MAXON Synchro ow control
valve. The multiple screw cam assembly provides mechani­cal adjustment capabilities to the fuel ratio at each valve position throughout the entire capacity range.
OPERATION
Fuel is delivered to the metering system at 50 to 70 psi. Metered oil is delivered to the common port of a 3-way solenoid valve for transfer to the burner nozzle through the normally closed port or back to the storage tank through the normally open port. During pre- and post purge, metered
oil is returned to the tank. During normal ring, all metered
oil is delivered to the nozzle. Air enters a rotary vane compressor through an air cleaner
where it is compressed to atomizing pressure. Air ows
from the compressor to an air/oil tank which serves the multiple purpose of dampening air pulsation, lube oil mist recovery, lube oil and atomizing air storage. Oil vapor is extracted by a mist eliminator in the upper section of the tank. Atomizing air from the upper tank section is delivered to the nozzle at a constant volume. Air pressure increases
as the burner ring rate increases. Atomizing pressure may
be adjusted by the valve located on the compressor air breather. The valve allows air to be bled from the tank to the compressor inlet. Delivery rate of the fuel oil metering is controlled by the modulating motor through adjustable linkage.
Figure 1-3
Sec1:5
I. GAS SYSTEM Gas is introduced into the combustion zone from a
circular manifold through multiple ports in the blast tube, and through a pre-mix zone. Firing rate is determined by the size and number of ports, by manifold pressure and by
combustion zone pressure. The ring rate is regulated by a rotary, buttery type throttling valve at the manifold inlet.
The valve is actuated by an adjustable linkage from the
modulating motor. Depending upon specic requirements,
one or two safety shutoff, motorized main gas valves are provided for installation in the gas train upstream of the
buttery valves. Safety shutoff gas valves are wired into
the programming control to automatically open and close at the proper time in the operating sequence.
MAIN GAS TRAIN COMPONENTS
Depending upon the requirements of the regulating au­thority, the gas control system and gas train may consist of some, or all, of the following items. A typical gas train is shown in Figure 1-4.
GAS VOLUME VALVE.
Two buttery type valves are positioned by linkage from the modulating motor and controls the rate of ow of gas.
MAIN GAS VALVES.
Electrically operated safety shutoff valve(s) that open to admit gas to the burner. Standard U.L. burners include: One motorized gas valve w/closure interlock and one standard motorized valve.
MAIN GAS REGULATOR
Regulates gas train pressure to specied pressure re­quired at inlet to gas train. Input is set by main gas pressure regulator adjustment.
MAIN GAS COCKS
For manual shutoff of the gas supply upstream of the pressure regulator. A second shutoff cock downstream of the main gas valve(s) provides a means of testing for leakage through the gas valve(s).
HIGH GAS PRESSURE SWITCH.
A pressure actuated switch that remains closed when gas pressure is below a pre-selected setting. Should the pressure rise above the setting, the switch contacts will open causing main gas valve(s) to close. This switch requires manual reset after being tripped.
LOW GAS PRESSURE SWITCH.
A pressure actuated switch that remains closed when gas pressure is above a pre-selected setting. Should the pressure drop below this setting, the switch contacts will open, causing main gas valve(s) to close. This switch requires manual reset after being tripped.
PILOT GAS TRAIN
GAS PILOT VALVE.
A solenoid valve that opens during the ignition period to admit fuel to the pilot. It closes after main ame is estab­lished.
GAS PRESSURE REGULATOR. Reduces gas pressure to that required by the pilot.
GAS PILOT SHUT-OFF COCK. For manually closing the pilot gas supply.
Sec1:6
Figure 1-4
OPERATION
Metered gas ows through the main gas shutoff cock,
through the pressure regulator to the automatic gas valves
and buttery valve to the gas manifold. The buttery gas valve modulates ow to burner input demand. The buttery valves are positioned through
mechanical linkage by the modulating motor. The air control damper is positioned simultaneously by the modulating motor. The automatic gas valve(s) cannot be energized unless the combustion air proving switch is closed. The low and high gas pressure switches must be closed to prove proper gas pressure. A normally open vent valve, if required, is located between the two automatic gas valves. This valve is shut when the automatic gas valves are open. When the automatic valves are closed, the vent valve is open for venting gas to the outside, should any be present.
Sec1:7
CHAPTER 2
INSTALLATION
A. APPLICATION
Electrical power available is usually 230/460 volt, 3 phase, 60 cycle, or 380 volt, 3 phase, 50 cycle. Control circuit is 115 volt, single phase, 60 cycle or 115 volt, single phase, 50 cycle. Refer to the electrical schematic diagram shipped with the burner. Power connections are made at the control panel. The burner is furnished with a burner mounted junction box and remote control panel. Wiring from the burner junction box to remote panel, panel to boiler controls, low water controls, remote compressor motor and remotely located fuel valves is furnished by the installer.
B. INSTALLATION
Locate the burner properly. The burner is designed for operation with the blast tube level. Do not tilt burner up or excessively downward. Installation of the refractory oven or combustion cone, shipped with the burner, is shown in Figures 2-1 and 2-2. Securely support the burner pedestal
on the oor or foundation. Allow enough clearance at the
rear of the burner to allow the housing to swing open for service and maintenance. The face of the boiler and burner
ange must be sealed with the gasket provided with the
burner. Carefully place the gasket over the dry oven bolts
before it is mounted onto the burner ange. The I.D. of
the dry oven and burner blast tube are concentric. Due to bolt hole tolerances, the dry oven may have to be shifted to accomplish this. After the dry oven nuts are properly tightened, the burner and dry oven assembly can then be mounted into the boiler.
C. PACKING PLASTIC REFRACTORY AROUND OVEN
The area between the outside circumference of the dry oven and existing refractory should be packed with Kaiser Refractory Mono T-9 Airset or equal within two hours after coating the dry oven with Trowleze. From inside the furnace, ram plastic refractory from the front to the rear parallel to outside surface of the dry oven.
supply entrance and pass through the return line and on to the tank. Metered oil is pumped (by the metering pump) to the common port of a 3-way valve. With the 3-way valve de-energized, the metered oil returns to the tank through the back pressure valve and return line. When the 3-way valve is energized, metered oil is passed on to the burner oil nozzle and atomized by air from the compressor. The proper strainers, check valves, vacuum and pressure gauges, etc. should be installed as indicated. All lines should be pressure tested after installation.
CAUTION
IT IS IMPORTANT THAT YOU PROVIDE S U P P O R T F O R T H E H O U S I N G WHEN IN THE OPEN POSITI O N TO PREVENT DAMAGE TO THE HINGES AN D SUBSEQUE NT COMPONE NTS.
F. CIRCULATING OIL PUMP A circulating oil pump is required to deliver fuel oil from
the storage tank to the burner at a minimum of 150% of
the maximum burner ring rate. The excess oil allows a
margin for piping error, viscosity changes in the fuel oil, and circulating pump wear. Correct pipe sizing is deter­mined by circulating rate , not burner capacity. Install the pump as close to the supply tanks as possible. Suction lift should be as low as possible. Maximum suction of 15" Hg vacuum is good practice for either light or heated heavy oil. The strainer should be installed in the suction line just ahead of the circulating pump to prevent foreign material from entering the pump. Locate the strainer so it may be easily cleaned.
G. OIL PRESSURE REGULATOR
An oil pressure regulator should be installed in the sup­ply line, close to the burner to regulate oil pressure. Oil pressure is 50 to 70 PSI to the metering valve.
D. SEPARATE COMPRESSOR MODULE
For oil burners supplied with the separate compressor module, piping to the burner is installed as shown in Figure 2-4. Copper tubing for the installation is not supplied with the burner.
E. TYPICAL OIL SUPPLY LOOP
Continuous oil circulation must be supplied to the burner
at a rate of 50 percent greater than the high-re burning
rate. The oil circulating pump should be located as close as possible to the storage tank to keep suction lines short and minimize suction loss. Note that the supply line is higher above the burner metering pump inlet to help eliminate air problems. The return line to the tank is connected at the discharge port of the 3-way valve. Note that the return line should be a minimum of 20 inches higher than the supply line. Since air rises to the highest point, it will rise from the
Sec1:8
H. GAS PIPING
Refer to Figures, 2-6 for typical gas piping schemat­ics. Gas service and house piping must supply the quantity of gas demanded by the unit at the pressure required at the burner gas train inlet. All piping must be in strict accor­dance with applicable codes, ordinances and regulations of the supplying utility. In the absence of other codes, piping should be in accordance with the following standards: "National Fuel Gas Code" NFPA No. 54, ANSI No. Z 223.1. (for Canada: the Canadian Gas Association (CGA) B149 and Canadian Standards Association (CSA) B140 codes shall prevail)
Gas train components upstream of the buttery valve
are shipped loose. These components should be mounted
by the installer as close to the buttery valve as practical.
Normally, the control train is ordered to suit a particular code

or insurance regulation - such as Underwriters Laboratories , Inc., CGA, Factory Mutual, or Industrial Risk Insurance. Arrange gas piping at the burner so that the burner is accessible for servicing without disassembly. The gas pilot supply line must be connected upstream of the main gas regulator. If a reducing bushing is required between the house piping and the burner piping, it should be close to the burner shut-off valve. The gas piping must be internally clean and free of foreign material. Before using in service, a leak test must be performed.
I. INSTALLATION CHECKLIST
All burners are carefully assembled and tested at the factory, but before being placed in service, all connectors should again be checked for looseness caused during shipment. Check:
1. Electrical terminals in the control panel and on all electrical components.
2. Pipe ttings and unions.
3. Tubing connections.
4. Nuts, bolts, screws.
Before operating pumps, metering heads and compres-
Figure 2-3
sors, make certain that reservoirs are properly lled with the specic lubricant. Open all necessary oil shut-off
valves. Do not run compressors, pumps, or metering units without oil. Before connecting electrical current to any component,
be sure the supply voltage is the same as that specied
on component nameplates. Before burner operation, be sure all motors are rotating in the correct direction. See Motor Rotation Reference on Sec1:13.
Before ring, make sure that the refractory ame cone is properly sealed to the burner mounting ange and the
boiler front plate. Make certain that the operator in charge is properly instructed in the operation and maintenance procedures.
CAUTION
THE BURNER REFRACTORY CONE IS AIR-CURED ONLY. HEAT-CURING MUST BE INITIATED AT INITIAL START-UP. RUN THE BURNER AT LOW FIRE FOR A PERIOD OF 6 TO 8 HOURS BEFORE STARTING TO GRADUALY INCREASE THE FIRING RATE. FAILURE TO DO SO WILL RESULT IN DAMAGE AND CRACKS IN THE REFRACTORY.

CHAPTER 3
OPERATION
A. PREPARATIONS FOR STARTING
When the installation is complete and all electrical, fuel, water and vent stack connections are made, make certain said connections are tight. The operator should become familiar with the burner, boiler controls and components. To identify controls and components, refer to contents of Chapter 1. Adjustment procedures given in Chapter
4 should be reviewed prior to ring. The wiring diagram
should also be studied along with the operating sequence of burner programmer. Read and understand starting instructions before at­tempting to operate the burner. Before attempting to start the burner, the following checks must be made:
1. BOILER.
Check the boiler water level. Be sure all boiler valves are installed correctly and positioned properly. Set the high limit control sightly above the desired temperature. Set modulating controls at the desired temperature or pressure.
2. BURNER. Check the electrical power supply to the burner in ac­cordance with the nameplate voltage on all motors and the control circuit. Check the direction or rotation of the motors. Open the housing to check the electrode setting. Refer to Chapter 5, Figure 5-2, Sec1:30. Check the gas pilot pressure at the pilot gas regulator. Normal setting is 18" to 20" W.C.
For protection in shipment, the ame safeguard control
chassis is shipped unmounted. Check all screw connec-
tions before attaching ame safeguard chassis to base.
Screw must be secure to assure low resistance connec­tions. The relay chassis is mounted on the sub-base with a screw which, when tightened, completes the connection between the sub-base and chassis contacts. Press manual reset button to be sure safety switch contacts are closed. Check control linkage for proper movement of the air volume damper and fuel metering components. This can be done by loosening the linkage at the actuator level and manipulating by hand.
Check the air shutter and adjust low-re setting.
3. FIRING PREPARATIONS FOR OIL BURNERS.
Prior to initial ring, oil ow pressure and temperature should be veried.
Inspect the compressor lube oil sump level. Add oil to bring the oil level to the midpoint or slightly higher in the reservoir sight glass. Fill with non-detergent SAE30 oil. Make certain that the drive belts or couplings are aligned and properly adjusted.
To verify air ow and pressure, momentarily ip the switch
“ON” and immediately turn “OFF”. The programmer will continue through its cycle, however, without ignition or en­ergizing the fuel valves. Observe the air pressure gauge.
With compressor running and no oil ow, the pressure
should be approximately 10 psi. If the burner is a dual fuel model, make certain that the main gas shut off cock is closed and the fuel selector switch set to “OIL”.
OIL FLOW.
Open all valves in the oil suction and return line. The burner oil metering units are not capable of creating suction. Fuel oil must be supplied to the metering unit at a nominal 50 to 70 psi pressure by a circulating supply pump. A vacuum (or compound pressure-vacuum) gauge should be installed in the oil suction line, and its reading noted. This gauge indicates the tightness of the suction system.
4. OIL- AIR TANK (LUBE OIL). Check the lube oil level in the air-oil tank. Inspect oil level regularly. Loss of oil will damage the compressor. Fill the tank with non detergent SAE30 oil to a level midway up
the sight glass. Do not overll the tank.
For normal environment use SAE30 oil. For a 32 degree F. and below environment use SAE10 oil. Change oil every 2000 hours of operation.
5. FIRING PREPARATIONS FOR GAS BURNERS.
A representative of the gas utility should turn on the gas. Determine by a test gauge upstream of the burner regulator
that sufcient pressure exists at the entrance to the gas
train. The gas pressure regulator must be adjusted to the pressure required and the pressure setting recorded. On combination fuel models, set the selector switch to gas. On initial start-up, it is recommended that the main gas shutoff cock remain closed until the programmer has cycled through pre-purge and pilot sequences to determine that the main gas valve opens. Turn the burner switch "OFF"
and let programmer nish its cycle. Check to see that gas
valve closes tightly. Set the high and low gas pressure switches. Check for leaks and determine there is adequate gas pressure available at the burner for operating at full capacity. Check with the local utility if necessary. Check gas pres­sure at the pilot and the main burner. Close the manual gas valve.
B. ELECTRICAL INTERFERENCE TEST
Prior to putting the burner into service, conduct the fol­lowing test to ascertain that the ignition spark will not cause
the ame relay to pull in.
1. GAS FIRED.
Close the pilot and the main line manual gas valves. Start the burner and at time of pilot trail with just the
electrical ignition system energized, the ame relay
should not pull in (i.e. be energized). Upon completion of successful test, proceed with start-up proceedures.
Sec1:16
2. OIL FIRED
Disconnect the electrical power to the burner. Disconnect the electric oil safety shutoff valve. Reconnect electric power to the burner. Close the pilot line manual gas valve, if used. Start burner and at the time of pilot trial, with just the
electrical ignition system energized, the ame relay
should not pull in. Upon completion of successful test, disconnect power supply. Reconnect oil safety shutoff valve and turn on manual pilot gas valve. Reconnect power supply and proceed with start-up procedures.
C. GAS PILOT FLAME ADJUSTMENT
The gas pilot ame is regulated by adjusting the pres­sure setting of the pilot regulator. Normal setting is 18"
to 20" WC when the pilot is burning. The ame must be sufcient to be proven by the ame detector and ignite the main ame.
Although it is possible to visibly adjust the size of the
pilot ame, obtain a proper DC volt or microamp reading of the ame signal. The ame safeguard amplier has a meter jack for this
purpose. At initial start-up and during planned maintenance,
test the pilot ame signal, pilot turndown, and safety switch
lockout.
D. START-UP SEQUENCE
The programming control sequences the operation of all controls and components through the starting, ignition, r­ing, and shutdown cycle. The burner and control system are in starting condition when: a. The operating and high limit control (temperature or pressure) are below their cutoff setting; b. All power supply switches are closed; c. Power is present at the control panel. Refer to the manufacturers literature on programming controls and burner wiring diagrams for detailed informa­tion.
Begin starting sequence, with burner switch off, and 1. with all manual valves closed. Switch main power on. (Power On) light.
When ring oil, open the manual oil valves.2.
When ring on gas, open the main manual gas valve.3.
When ring on gas, manually reset the high and low 4.
gas pressure switches.
Place the gas / oil selector switch in position for 5. desired fuel. With all limit and operating controls calling for heat, the burner will follow the Flame Safeguard Sequence below.
When the burner motor starts, open the gas cock.6.
If ring on gas, when the main fuel lamp lights 7. indicating pilot ame proven open the the manual
leak test valve.
Time in Seconds External Operation
0 Provided the fuel valve is proven closed

7 Air ow must be proven before ignition,
or the ame safeguard will lockout. If the interlock circuit opens during a ring
period, the burner will shut off and the
ame safeguard will lockout.
60 Firing on gas and providing the air ow
and low-re have been proven, the pilot
ignition transformer and ignition lamp are energized and the gas pilot valve opens to ignite the pilot.
70 Firing on oil, providing air ow and pilot
have been proven, the main fuel lamp lights. When on gas or oil, the main valve opens to ignite the burner at low
re.
80 The pilot ignition transformer is de-ener-
gized, and the main safety shut-off pilot
valve closes, scanner proves main ame
only. If the low/auto swtich is in the auto position, the following will occur:
On gas, the buttery valve and the burn­er air louvre moves to "low-re" position.
On oil, the metering pump and the burner
air louvre moves to "low-re" position.
100 "Normal run" position. Burner continues.
E. AUTOMATIC SHUTDOWN
Limit or operating controls open:
100 Fuel valves close. Main fuel lamp goes
off. Flame safeguard timer starts.
115 Flame safeguard timer and burner motor
stop. Burner is ready for start-up on the next call for heat.
F. MANUAL SHUTDOWN
1. Turn gas/oil selector switch off. Burner shuts down in Automatic Shutdown as above.
2. When burner motor stops, close all manual valves.
G. SAFETY SHUTDOWN
1. If at any time during the operating cycle a ame failure
occurs, the burner shuts down as in Automatic Shutdown,
with an additional post-purge, and the ame failure lamp
is energized.
A. The lockout switch on the ame safeguard control must be manually reset before the burner will re
again.
2. If a low water condition occurs, the burner shuts down as in Automatic Shutdown.
3. If a high or low gas pressure condition occurs while
ring on gas, the burner shuts down as in Automatic
Shutdown.
A. Condition must be corrected and the respective gas pressure switch manually reset before the burner
will re again on gas.
Sec1:17
H. START-UP AND OPERATING
GAS BURNERS
Close the main and pilot gas cocks. Make sure the “ON-OFF” switch is in the “OFF” position and the fuel se­lector switch on “GAS”. Actuate the manual reset button
of the ame safeguard control to close the safety switch
contacts. Set the “MANUAL-AUTO” switch in the “MANUAL” position.
Set the manual potentiometer in low re position.
Open the gas pilot cock.
Set the “ON-OFF” switch to “ON”. The burner will start and pre-purge. After pre-purge, the ignition transformer and the gas pilot solenoid are energized. Before proceeding, conduct electrical interference and pilot turndown tests if not previously done. Refer to Paragraph B.
On initial start-up it is recommended that the main gas shutoff cock remain closed until the programmer has cycled through prepurge and pilot sequence. Then determine that
main gas valve opens. When this is conrmed, turn the burner switch “OFF” and let programmer nish its cycle.
Check to see that gas valve has closed tightly. If ignition does not occur, turn the burner switch “OFF” and allow programmer to recycle for a new ignition trial.
start-up of a combination burner, it is recommended that
oil ring be adjusted before gas ring. Gas low ring rate is set to match oil low re rate.
Be sure the “ON-OFF” switch is in the “OFF” position and the fuel selector switch is on “OIL”. Actuate the manual
reset button of the ame safeguard control to close the
safety switch contacts. Be sure the “MANUAL-AUTO” switch is in “MANUAL” position. Set manual modulating
control potentiometer in “LO” re position.Open the pilot
gas valve (if used).
Set the “ON-OFF” switch to “ON”. The burner will start and pre-purge. After pre-purge, the ignition transformer and the gas pilot are energized. Before proceeding, con­duct electrical interference and pilot turndown tests if not previously done. Refer to Chapter 4, Sections C and D.
Observe the primary atomizing air pressure gauge on the air/oil tank. The gauge reading should be approximately 10 psi during pre-purge.
When the pilot ame is proven, the programmer will pro­ceed to the main ame position. Allow the burner to operate in low re, to warm the boiler before moving to high-re.
Turn burner “ON” and after pilot ignition when the ame
relay pulls in, the slow opening, motorized, main gas valve is energized. Slowly open the downstream manual shutoff
gas cock. Main ame should ignite at this time. The gas valve and air damper continue advancing until high re is
reached. Do not repeat unsuccessful light off attempts without rechecking burner and pilot adjustment. Vent fuel vapors from the combustion chamber after each unsuccessful
light off attempt. Set the gas low re rate by adjusting buttery valve and air linkage. When low re is adjusted,
shut down burner. Restart several times to be sure the
low re setting is suitable. Readjust if necessary. Never
start the burner with fuel vapor in the furnace. In case of emergency, open main power switches and close all fuel valves. After combustion adjustments are satisfactorily set, allow the heating vessel to slowly reach normal operating pressure or temperature.
Turn the potentiometer switch to the high re position. Check high re at this point using combustion instru-
ments.
Do not disturb established low re adjustment. Allow the burner to return to low re position before adjusting high
or intermediate settings.
High re combustion analysis typically is 9 to 10.5 percent
CO2. When conditions covered above are assured, refer to Sections I and J.
OIL BURNERS
The fuel selector switch should be set to “OIL”. On initial
Typically, for No. 2 through 4 oil, CO2 is 8 to 11 percent
at low re.
Turn the manual potentiometer switch to the high re position. Check high re combustion at this point. Do not disturb previously established low re adjustment. Allow the burner to return to low re position before adjusting
high or intermediate settings. The primary atomizing air
pressure will increase automatically with the oil ow rate.
Typically, for No. 2 oil, CO2 is 10 to 13 percent at high
re.
When conditions covered above are assured, refer to sections I and J
I. NORMAL OPERATION
Normal operation must be with the “MANUAL-AUTO” switch selector at “AUTO”. In automatic operation, the operating cycle always pro­ceeds sequentially through pre-purge, pilot ignition, main
ame ignition, run and post-purge. The length of purge
and ignition trial vary according to the type of programmer used. During the run cycle, burner input is regulated to the load demand by the modulating pressure or temperature control on the boiler. The burner will continue to modulate until the operating pressure or temperature is reached. Programmer control operation should be tested when the burner is initially placed into service, when a control is replaced, and at scheduled intervals in the maintenance program. Refer to adjustment procedures and maintenance instruc­tions given in Chapters 4 and 5.
Sec1:18
J. SHUTDOWN
When the operating limit control setting is reached or the burner switch is turned “OFF”, the following sequence occurs:
The fuel valve(s) de-energize and ame extinguishes.
The blower motor continues running during post-purge. At the end of the post-purge, the blower motor is de-en­ergized. The programmer returns to its starting position and stops. Unit is ready to restart. Abnormal shutdown might result from motor overload,
ame outage, low water, current or fuel supply interruption,
combustion or atomizing air pressure below minimum level, tripped circuit breakers, blown fuses, or other interlock devices. Check for cause and correct before restarting burner.
Safety shutdown caused by ignition or ame failure will
actuate a red indicator light and energize an audible alarm (if so equipped). If the programmer has a non-recycling interlock circuit, any interruption in this circuit during the
pre-purge or ring cycle will cause a safety shutdown. This
type of shutdown requires manual reset of the program­ming control and must be corrected before operation can be resumed.
WARNING
AN ULTRAVIOLET FLAME SENSOR ELECTRICAL SPARK INTERFERENCE TEST MUST BE PERFORMED AFTER FINAL ADJUSTMENT. SEE THIS SECTION PARAGRAPH
"B" FOR ADDITIONAL INFORMATION.
Sec1:19
CHAPTER 4
ADJUSTMENTS
A. GENERAL
While each burner is tested at the factory for correct operation before shipment, variable conditions such as burning characteristics of the fuel used and operating load conditions may require further adjustment after installation
to assure maximum operating efciency.
Prior to placing the boiler into initial service, a complete inspection should be made of all controls, connecting piping, wiring and all fastenings such as nuts, bolts and setscrews to be sure that no damage or misadjustments occurred during shipping and installation.
A combustion efciency analysis made during the initial
start-up will help to determine what additional adjustments are required in a particular installation.
B. COMBUSTION ADJUSTMENT ON GAS AND OIL
Efcient combustion cannot be properly judged by ame
appearance, although it may help in making preliminary settings. The proper settings of air-fuel ratios must be determined
by ue gas analysis. Combustion gas analysis indicates
the air to fuel ratio and the degree of complete combustion. Instruments are available to measure carbon dioxide (CO2), oxygen (O2), and carbon monoxide (CO).
STACK TEMPERATURE Net stack temperature is obtained by subtracting the
ambient temperature from the ue gas temperature. A
high net stack temperature indicates wasted heat. Stack temperature should be as low as possible without causing
ue gas condensation.
Stack heat loss can be reduced by decreasing either the
temperature or the volume of the ue gas, or both. Flue
gas temperature is reduced by improving heat transfer or by reducing excess combustion air. A certain amount of excess air is necessary to complete combustion. More
efcient burners require minimum excess air.
SMOKE MEASUREMENT
Smoke measurements can be made using a variety of different methods. The standards will vary somewhat according to the equipment used, and instructions accom­panying the instrument should be followed. Smoky combustion can result from: Improper air delivery,
insufcient draft, improper fuel viscosity, improper fuel-air
ratio, excessive air leaks in the combustion chamber, or improper fuel oil temperature.
GAS ADJUSTMENTS
Low re combustion analysis typically is 7 to 9 percent
CO2 and less than .04 percent CO (400 ppm). High re reading typically is 9 to 10.5 percent CO2 and less than .04 percent CO.
FUEL OIL ADJUSTMENTS
Adjust for a “clean re”. Typically for No. 2 oil, CO2 is 8 to 11 percent at low re and 10 to 13 percent at high re,
with a maximum of #1 spot (ATSM D2156 Shell-Bacharach scale).
C. ELECTRICAL INTERFERENCE TEST
Prior to putting the burner into service, conduct the fol­lowing test to ascertain that ignition spark will not cause
the ame relay to pull in.
GAS FIRED
Close the pilot and main line manual gas valves. Start the burner and at time of pilot trial with just the
electrical ignition system energized, the ame relay should
not pull in (i.e. be energized). Upon completion of successful test, proceed with start-up procedures.
OIL FIRED
Disconnect the electrical power to the burner. Disconnect the electric oil safety shutoff valve. Reconnect electric power. Close the pilot line manual gas valve, if used. Start burner and at the time of pilot trial, with just the
electrical ignition system energized, the ame relay should
not pull in. Upon completion of successful test, disconnect power supply. Reconnect oil safety shutoff valve and turn on manual pilot gas valve. Reconnect power supply and proceed with start-up procedures.
D. GAS SYSTEM
GAS PRESSURE
Gas must be supplied at a pressure high enough to overcome the pressure loss in the burner gas train and furnace pressure while running at full input. Refer to name­plate inside control panel for gas pressure requirements at train inlet and manifold. The pressures listed are based on nominal 1000 Btu/cu ft natural gas at elevations up to 2000 feet above sea level.
GAS FLOW
The volume of gas is measured in cubic feet as determined
by a meter reading. The gas ow rate required depends
on the heating value (Btu/cu ft). The supplying utility can provide this information as well as pressure correction factors. To determine the required number of cubic feet per hour of gas, divide burner input (Btu/hr) by the heating value (Btu/cu ft).
NOTE
WHEN CHECKING THE INPUT RATE, MAKE SURE NO OTHER EQUIPMENT IS OPERATING ON THE SAME METER.

MAIN GAS PRESSURE REGULATOR
The gas pressure required at the burner manifold is the pres-
sure that is required to re the burner at its rated capacity.
The gas pressure regulator must be adjusted to achieve this pressure to assure full input. Refer to manufacturer’s literature for regulator adjustment.
WARNING
AN ULTRA-VIOLET FLAME SENSOR ELECTRI­CAL SPARK INTERFERENCE TEST MUST BE PERFORMED AFTER FINAL ADJUSTMENT. SEE SECTION C OF THIS CHAPTER FOR ADDITIONAL INFORMATION.
LOW GAS PRESSURE SWITCH Turn adjusting screw until indicator moves to a pressure setting slightly below the operating gas pressure. The control will break a circuit if pressure is below this set point.
The control should be nally adjusted to prevent operation
with low gas pressure, but not at a pressure so close to normal operating pressure that unnecessary shutdowns occur. The switch must be manually reset after tripping. To reset, allow gas pressure to rise and press the manual reset button.
reading. With the high re air-fuel ratio established, the gas pres­sure regulator needs no further adjusting.
Recheck low re and adjust if necessary.
Proper setting of the air/fuel ratios at all rates must be determined by combustion analysis.
GAS VALVES ADJUSTMENT
The secondary valve feeds gas to the inner spuds. A slot in the valve stem in relationship to the shut/open scale on the valve indicates the blade position. Both low and high-
re positions are approximate. Adjustments to the valve
should be made on the secondary valve linkage arm. To increase the travel, move the linkage arm closer to the pivot point. To decrease the travel, move the linkage arm away from the pivot point. The primary valve which feeds the outer spuds should be adjusted as normal. See Diagrams 4-5 at the end of this section for adjustments.
HIGH GAS PRESSURE SWITCH
Turn adjusting screw until indicator moves to a pressure setting slightly above the maximum operating gas pressure. The control will break a circuit if pressure exceeds this value. The control should be adjusted to prevent operation with excessive gas pressure, but not at a pressure so close to normal operating pressure that unnecessary shutdowns occur.This switch must be manually reset after tripping. To reset, allow gas pressure to drop and press the manual reset button.
GAS COMBUSTION ADJUSTMENT
After operating for a sufcient period of time to assure a warm boiler, make adjustments for most efcient combus­tion.The buttery gas valve directly controls the rate of ow. The low re light-off setting should be regarded as preliminary until proper gas pressure for high re operation
is established.
Determine the actual gas ow from a meter reading at high re. With the buttery valve open and with regulated gas pressure set, the actual ow rate should be quite close
to the required input. If corrections are necessary, increase or decrease the gas pressure by adjusting the gas pressure regulator, following manufacturer’s directions for regulator adjustment.
When proper gas ow is obtained, take a ue gas analysis
Figure 4-1
CAM TRIM ADJUSTMENT
Fine tuning the modulating cam.
After low and high re adjustments are complete, nal
adjustment is made with the cam assembly to obtain a
good air/fuel ratio throughout the entire ring range. The input of combustion air is xed at any given point in the
modulating cycle. The fuel input may be varied to obtain
correct ue gas readings. The adjustment is made to the
metering cam by means of the 14 adjusting screws which are turned in (clockwise from the hex-socket end) to in-
crease the ow of fuel, and out (counterclockwise from
the hex-socket end) to decrease it. A 3/32" hex key is required. It will be necessary to cut off the short end of the
hex key to approximately 3/8" to adjust the rst two socket head setscrews at the low re position. Take a combustion analysis at various points of the cam prole. Adjustment

E. OIL SYSTEM
OIL METERING SYSTEM.
Fuel oil supply to the integral metering unit must be 50 to 70 psi. The oil spray should ignite as soon as the oil solenoid valve opens. If a burner failure occurs, check the following:
1. See that the oil tanks are not empty.
2. That all oil valves between the burner and the tank are open.
3. That the suction line is not airbound.
4. That the low-re setting has not been disturbed.
5. That there is pressure at the integral metering unit, but not to exceed 80 psi.
6. That the circulating pump turns freely.
7. Check for a clogged strainer at the suction side of the circulating pump.
8. Check for a dirty burner strainer.
9. Check for a plugged or carboned nozzle. This will show up as excessive primary air pressure.
10.That the oil by-pass valve is not by-passing the metered fuel oil.
To adjust the metering valve, proceed as follows:
1. Check that the air dampers are closed.
2. During pre-purge, check that the valve travels its full quadrant range from minimum to maximum.
3. The oil ow is adjusted by screwing "in" the locking allen
screws located on the side of the valve. With SYNCHRO valve at minimum position, screw down (clockwise) to permit
fuel ow to the burner. Once your ame is established and rened at this position, screw all remaining screws down at
Sec1:22
least the same level as your rst adjusting screw.
4. A preliminary setting can be established with all the re­maining screws. Generally each succeeding screw needs to be screwed in approximately one full turn deeper than its preceding screw. A smooth "stair-step" gradient pre­set at this point from low to high will simplify the remaining adjustment steps.
5. Adjust each screw to match the air supply and obtain a clean re. Take combustion analysis as referred in sec­tion B.
6. Advance valve to the #2 screw position and adjust.
7. Progressively work your way up through each adjusting screw position, developing a smooth progression slope from
your rst screw to the maximum position. Take combustion readings at each point. To adjust the ame at any position, you must move the ow control valve to the number you
desire to adjust. This aligns the adjusting screw directly on top of the fuel valve plunger. A resulting adjustment of the screw is directly applied to the fuel valve plunger and its interconnected valve body linkage.
8. Rene adjustments as needed, always turning valve so
that position indicator matches screw being adjusted. To avoid possible damage to cam strips, always turn all higher numbered screws in as far as the last one adjusted. For more fuel, turn screw in (clockwise). For less fuel, turn screw out (counter-clockwise). If screw must be turned
in ush with carrier casting, increase fuel pressure and
re-adjust.
9. Cycle burner from minimum to maximum and rene adjustments if necessary. Always set ow control valve to
the numbered position you wish to adjust. See Diagram 4-6 for adjustments.
ATOMIZING AIR PRESSURE.
Atomizing air in the air/oil tank is regulated by adjusting
valve in the return air line on integral metering units or in the air inlet on air compressor module burners. The air pressure is indicated by the pressure gauge at the air/oil
tank. A minimum of 10 psi air pressure in low re is sug­gested. As the ring rate increases, the air pressure also
increases. Air pressure will be less with light oils. If any change in atomizing air pressure is made, check ignition several times for reliable light off. Adjustments should be
set to obtain reliable ignition with best low and high re
combustion results. If the required atomizing air pressure cannot be maintained, a lack of lubricating oil may be the
cause or the intake lter may be dirty.
Figure 4-3
ATOMIZING AIR PROVING SWITCH. The knurled nut between the switch and bellows is turned in to raise pressure setting. The minimum amount of atom­izing air is during pre- and post-purge. During pre-purge, adjust switch until it breaks the circuit. Readjust switch above this circuit break point to actuate under a condition of minimum pressure, but not so close as to cause nuisance shutdowns. Since the pressure of the atomizing air is at minimum when no fuel is present at the nozzle, adjustment of the switch should be made while the unit is purging, but
not ring.
indicates the air to fuel ratio and the degree of complete combustion. The closer the rod comes to parallel with the lever, the slower the rod moves. The angles of the driven levers on the jackshaft can be adjusted to vary
the rate of good air/fuel ratio throughout the entire ring range. The input of combustion air is xed at any given
point in the modulating cycle. The fuel input may be varied to obtain correct ue gas readings. The adjust­ment is made to the metering cam by means of the 14 adjusting screws which are turned in (clockwise from
the hex-socket end) to increase the ow of fuel, and out
(counterclockwise from the hex-socket end) to decrease it. A 3/32" hex key is required. It will be necessary to cut off the short end of the hex key to approximately
3/8" to adjust the rst two socket head setscrews at the low re position. Take a combustion analysis at vari­ous points of the cam prole. Adjustment can be made
without cycling the burner; then operate the automatic modulating cycle to assure satisfactory results. Tighten the locking set screws.
G. FIRING RATE CONTROLS
Firing rate adjustments are made at the modulating motor linkages to the combustion air inlet damper, oil
metering valve and main gas buttery valve. Settings
are determined by the operating length of the levers and the angular position on the shafts. Increasing the lever lengths on damper, pump or valve decreases the
ow rate. Driving and driven levers are approximately
parallel, but the angles can be adjusted to vary the rate of change. The most rapid rod travel occurs when the lever is perpendicular to the rod. The closer the rod comes to being parallel with the lever, the slower the rod moves.
ALWAYS allow the burner to return to low re position before adjusting high or intermediate settings. DO NOT
alter low re settings. Normally, the air control damper will be almost closed in low re position. For best pilot
operation, the damper should be set as low as possible.
Excessive opening in low re can cause pilot ignition
problems. Air to the pilot is supplied under pressure to compensate for variations in furnace pressure, but the
damper must be in low re position for reliable ignition. (See Figure 4-4, 4-7, 4-8)
F. LINKAGE-MODULATING MOTOR
The linkage consists of adjustable cams, levers, rods and ball joints that transmit motion from the modulating motor to
the air damper, gas buttery valve, and oil metering unit.
When properly adjusted, coordinated movement of the air and fuel control devices provide proper fuel/air ratios
through the ring range. In linkage adjustments, several
important factors serve as guides:
1. The modulating motor must be able to complete its full travel range. Restrictions will damage the motor and /or the linkage.
2. Lever and rod adjustments should be made with
the motor in the low re position.
The modulating motor will be stopped at the end of its stroke by an internal limit switch. Combustion gas analysis

MAINTENANCE
WARNING
ANY COVER PLATES, ENCLOSURES, OR GUARDS ANCHORED TO THE BURNER, OR ANY BURNER RELATED EQUIPMENT, MUST REMAIN IN POSITION AT ALL TIMES. ONLY DURING MAINTENANCE AND SERVICE SHUTDOWN CAN THESE COVER PLATES, ENCLOSURES, OR GUARDS BE REMOVED. THEY MUST BE REPLACED, AND SECURELY ANCHORED BEFORE TESTING, ADJUSTING, OR RUNNING THE BURNER OR BURNER RELATED EQUIPMENT.
CAUTION
IT IS IMPORTANT THAT YOU PROVIDE SUPPORT FOR THE HOUSING WHEN IN THE OPEN POSI­TION TO PREVENT DAMAGE TO THE HINGES AND SUBSEQUENT COMPONENTS.
A. GENERAL
A maintenance program avoids unnecessary down time, costly repairs, and promotes safety. It is recommended that a record be maintained of daily, weekly, monthly, and yearly maintenance activities. Electrical and mechanical devices require systematic and periodic inspection and maintenance. Any “automatic” features do not relieve the operator from responsibility, but rather free him from certain repetitive chores, providing time for upkeep and maintenance. Unusual noise, improper gauge reading, leak, sign of overheating, etc., can indicate a developing malfunction, requiring corrective action.
tions demand. A periodic safety check procedure should be established to test the complete safeguard system. Tests should verify safety shutdown with a safety lock out upon
failure to ignite the pilot or the main ame, and upon loss of ame. Each of these conditions should be checked
on a scheduled basis. The safety check procedures are contained in the manufacturer’s bulletin.
D. FIRING HEAD INSPECTION
Disconnect the damper linkage, release the impeller housing latch and swing the housing open for access to the
ring head. Inspect the ame scanner lends to be sure it
is clean and the support tube is in proper position to sight
the ame through the hole in the diffuser. Inspect the lead wire to the ignition electrode. It must be rmly attached
and the insulation should be clean and free of cracks. The oil nozzle should be inspected periodically depending on the grade of oil burned and the cleanliness of the environ­ment.
E. PILOT AND IGNITION ELECTRODE
The ignition transformer requires little attention other
than making sure the ignition wire is rmly attached to the
transformer and the electrode. Be sure the wire insulation is in good condition and not grounded. Failure to keep the ignition electrode clean and properly set can cause faulty operation. Refer to Figure 5-1, for electrode gap setting and position. The pilot assembly is supported by a socket in the diffuser and gas inlet tube. No adjustment is required
except proper positioning of the electrode wire.
IGNITION PILOT ELECTRODE SETTING
GAP - 3/32"
B. CONTROL SYSTEM
Most operating controls require very little maintenance beyond regular inspection. Examine electrical connec­tions. Keep the controls clean. Remove any dust from the interior of the control. Covers should be left on controls at all times. Keep the control cabinet doors closed. Dust and dirt can damage motor starters and relay contacts. Starter contacts are plated with silver and are not harmed
by discoloration. Never use les or abrasive materials
such as sandpaper on contact points.
C. PROGRAMMING CONTROL
This control requires no adjustment, nor should any at­tempt be made to alter contact settings or timing logic. Those programmers with contacts may require occasional clean­ing. If so, follow instructions given in the manufacturer’s bulletin. Never use abrasive materials. The manufacturer’s bulletin also contains troubleshooting information. The ame detector lens should be cleaned as often as condi-

IT IS ESSENTIAL THAT THE CAM SPRING, CAM FOLLOWER BEARING WHEEL AND CAM FOLLOWER ARM AT THE PIVOT POINT BE GREASED SPARINGLY EVERY MONTH TO ENSURE SMOOTH OPERATION OF THE CAM ASSEMBLY. REGULAR AUTOMOTIVE BEAR­ING GREASE SHOULD BE USED.
G. OIL NOZZLE
Successful burner operation requires use of the proper style
nozzle tip and keeping the orice clean. Standard nozzle
tips furnished on the burners are of a special emulsifying
type which delivers a spray of extreme neness and at
an angle which insures proper mixing with the air stream. Unsatisfactory performance and loss of efciency can re­sult from the use of nonstandard nozzle tips. If the burner
ame becomes stringy or lazy, it is possible that the nozzle
spring is not properly in place or the nozzle is clogged. This problem is usually indicated by an abnormally high reading on the atomizing air pressure gauge on the air-oil tank. To

remove the nozzle, disconnect the oil and air tubes to the nozzle assembly. Refer to Figure 2. To clean the nozzle tip and swirler, unscrew the tip from the nozzle body. Use care not to distort the tube. Hold the nozzle body in a vise or use two wrenches, one on the body and one on the tip. Disassemble the nozzle tip. Carefully clean all parts in solvent and reassemble the nozzle. To insure proper atomizing, the tip must be screwed in tightly with the swirler seating spring pressing the swirler tight against the nozzle
tip. Turn the swirler a few times to be sure it ts snugly in the nozzle and the spring is pressing the two parts rmly
together. When reinstalling, be sure the nozzle is centered with the proper distance from the diffuser.
H. DIFFUSER
The diffuser is factory set and does not require attention under normal operating conditions. If fouled with carbon, the diffuser should be removed for cleaning. First remove the electrode and scanner leads, the gas pilot assembly, air and oil tubes and the nozzle support assembly, before you attempt to remove the diffuser. Mark the diffuser rela­tive position to the blast tube, with a scribed or pencil line where the three mounting screws are located, to insure that the diffuser is placed back in the same position. Remove the three screws holding the diffuser to the blast tube and slowly pull the diffuser along the blast tube towards the
ring head. Keep the diffuser as parallel as possible. If it
should became stuck or tight, do not apply any tool which
would distort the shape or blade conguration. A small
wooden block tapped gently against the diffuser's outer edge will help expedite its removal. Clean all carbon from the diffuser vanes and reinstall in reverse order,
Sec1:31
aligning the diffuser with the scribed marks. Do not at­tempt to drive the diffuser back along the blast tube with anything other than a small block of wood tapped against the diffuser's outer edge. When reinstalling, be sure the diffuser is centered.
I. FIRING RATE CONTROLS Check all rods and linkages. Make sure all connections
are tight. Adjust if necessary. Perform a combustion test as per Chapter 4 Adjustments, and readjust burner if nec­essary.
J. BURNER MOUNTING INSPECTION
The seal between the burner ange and furnace front
plate must not permit combustion gases to escape. Pe­riodic inspection is important. If leakage occurs, refer to Chapter 2, Section D for proper sealing procedure.
K. FUEL OIL SYSTEM
FUEL OIL CIRCULATING PUMP.
Failure of the circulating pump to deliver sufcient oil may
be due to one of the following reasons:
1. Insufcient fuel oil in the storage tank.
2. Suction line or check valve clogged.
3. Air leaks or air traps in the suction line. If the line has a high point at which an air trap can occur, the line must be changed.
4. Oil strainer clogged (line strainer or burner strainer).
5. Suction line piping too small.
6. Pump rotating in wrong direction
7. Three phase pump motor operating on single phase because of fuse failure.
8. Low voltage applied to pump motor.
PRIMARY AIR COMPRESSOR
The air compressor itself requires little maintenance,
however its life is dependent upon sufcient clean, cool
lubricating oil. The oil level in the air-oil tank must be checked regularly. Lack of oil will damage the compressor.
Disassembly or eld repairs to the air compressor are not
recommended. Check the air-oil tank sight glass for proper oil level. The level should be kept at midpoint up the glass. The compressor rotor must turn freely. All tube connections must be air tight. Alignment of the compressor and motor sheaves and proper belt tension are important. Belt tension is adjusted according to the displacement on the belt with thumb pressure. The displacement should be 3/8 to 1/2 inch. To adjust, loosen the two bolts on the compressor mounting
ange and the three setscrews which hold the compressor
in place.
The mounting ange is slotted at the top, which permits belt tightening. If the slot in the mounting ange is insuf­cient for obtaining proper belt tension, the modular base
has two extra holes for this purpose. Move the top bolt to the next hole and adjust. Tighten bolts and setscrews. Replace belt guards. If belt becomes frayed or cracked, replace it.
CAUTION
DO NOT ATTEMPT FIELD REPAIR OF THE COMPRESSOR. INSTALLATION OF A NEW COMPRESSOR IS MANDATORY. SEND THE OLD COMPRESSOR IN FOR REPAIR OR EXCHANGE (WHERE ALLOWED).
AIR CLEANER
Never operate the compressor without the air cleaner in place. The cleaner should be cleaned at regular intervals. The correct oil level must be maintained in the air cleaner. Use the same oil used for air compressor lubrication.
OIL-AIR TANK
Check the lube oil level in the oil -air tank. Inspect oil level regularly as loss of oil will damage the compressor. Change oil every 2000 hours of operation. The oil-air tank
should be drained once a year and thoroughly ushed.
Remove the mist eliminator pads from the upper section of
the tank, wash thoroughly in kerosene and dry. Rell with
non detergent SAE30 oil to a level midway up the sight glass. For normal environment use SAE30 oil. For a 32 degree F. and below environment use SAE10 oil.
OIL LEVEL SIGHT GAUGE The oil level sight gauge can be cleaned by removing it from the air-oil tank and soaking it in a detergent solution. If cleaning the gauge proves unsatisfactory, replace it.
COMPRESSOR OIL FILTER (Lube Oil Strainer)
The lube oil strainer prevents foreign materials from entering the compressor. The strainer screen must be cleaned at regular intervals. The screen is easily removed for cleaning by unscrewing the bottom plug. Immerse in solvent and thoroughly clean.
OIL STRAINERS
Oil strainers should be cleaned frequently to maintain
a free and full ow of fuel. The strainer screen must be
removed and cleaned at regular intervals. The screen should be removed and cleaned thoroughly by immersing it in solvent and blowing it dry with compressed air. Light oil strainers should be cleaned each month. Heavy oil strainers should be checked and cleaned as often as the experience indicates the necessity.
L. GAS SYSTEM
MOTORIZED MAIN GAS VALVES.
Should the valve fail to operate, check for voltage at the valve. Make certain that the main shutoff cock is closed
prior to testing. The actuator is not eld repairable nor
should it be disassembled. Replace the actuator if the valve fails to operate. After replacement, cycle the valve with the fuel shutoff to determine that it opens and closes. If the valve has a visual indicator, observe its position for correct operation.
Sec1:32
SOLENOID VALVES.
A slight hum from the solenoid is normal when the coil is energized. Should the valve fail to operate, check that there is voltage at the valve coil. If there is no voltage at coil, check for loose wiring connections. If there is proper voltage at the valve coil and the valve still fails to open, replace the coil. Refer to manufacturer’s bulletin for correct procedure in coil replacement. Should it become necessary to replace the complete
valve, be sure that the ow is in the drection of the arrow
on the body. Test for gas leaks and check valve action several times to ensure proper operation before attempting to relight burner.
CAUTION
ALL POWER MUST BE DISCONNECTED BEFORE SERVICING THE VALVES.
M. ELECTRICAL SYSTEM
Because of the many types of ame safeguard systems
applicable to this equipment, complete descriptions of all D/Series burner electrical systems are beyond the scope of this manual. An individual electrical schematic drawing is shipped with each burner and complete operation and troubleshooting instructions are available from the various
ame safeguard system manufacturers.
ELECTRIC MOTORS.
Motor supply voltage must not vary more than 10 percent from nameplate ratings. At initial start-up and at least once a year thereafter, check the motor current with a meter while
the burner is in high re position. If the reading exceeds
the nameplate rating plus service factor, determine the cause and correct it immediately. In dusty locations, clean the motor regularly to assure adequate cooling. Lubricate in accordance with the manufacturer’s instructions.
N. EXTENDED SHUTDOWN
When shutting down the burner for an extended period of time, the operator should use the following general guide­lines to protect the burner from its surrounding elements. This will add to the operating life of the burner.
1. Turn the main electrical disconnect switch to the burner to OFF.
2. Close all main fuel valves.
3. If the burner operates in a damp environment, cover it with plastic to protect all electrical components
from moisture. Remove the ame safeguard control
and store in a dry atmosphere.

TROUBLE SHOOTING SHOULD BE PERFORMED ONLY BY PERSONNEL WHO ARE FAMILIAR WITH THE EQUIPMENT AND WHO HAVE READ AND UNDERSTOOD THE CONTENTS OF THIS MAN­UAL. FAILURE TO FOLLOW THESE INSTRUC­TIONS COULD RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
WARNING
DISCONNECT AND LOCK OUT THE MAIN POW­ER SUPPLY IN ORDER TO AVOID THE HAZARD OF ELECTRICAL SHOCK. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN SERI­OUS PERSONAL INJURY OR DEATH.
A. AWARENESS
Chapter 6 assumes that:
1. The unit in question has been properly installed and that it has been running for some time.
2. The operator has become thoroughly familiar with both the burner and the manual by this time.
The points set forth under each heading are brief, pos­sible causes, suggestions or clues to simplify locating the source of the trouble. Methods of correcting the trouble,
once it has been identied, may be found elsewhere in this
manual.
If the burner will not start or operate properly, the Trouble Shooting Section should be referred to for assistance in pinpointing problems that may not be readily apparent.
The program relay has the capability to self-diagnose and to display a code or message that indicates the failure
condition. Refer to the control bulletin for specics and
suggested remedies.
Familiarity with the programmer and other controls in the system may be obtained by studying the contents of this manual. Knowledge of the system and its controls will make trouble shooting that much easier. Costly downtime or delays can be prevented by systematic checks of actual operation against the normal sequence to determine the stage at which performance deviates from normal. By following a set routine may possibly eliminate overlooking an obvious condition, often one that is relatively simple to correct.
If an obvious condition is not apparent, check each con­tinuity of each circuit with a voltmeter or test lamp. Each
circuit can be checked and the fault isolated and corrected. In most cases, circuit checking can be accomplished between appropriate terminals on the terminal boards in the control cabinet or entrance box. Refer to the wiring
schematic supplied for terminal identication.
NEVER ATTEMPT TO CIRCUMVENT ANY OF THE SAFETY FEATURES.
WARNING
THE CAUSE FOR LOSS OF FLAME OR ANY OTHER UNUSUAL CONDITION SHOULD BE INVESTIGATED AND CORRECTED BEFORE ATTEMPTING TO RESTART. FAILURE TO DO SO MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
WARNING
DO NOT REPEAT UNSUCCESSFUL LIGHTING ATTEMPTS WITHOUT RECHECKING THE BURNER AND PILOT ADJUSTMENTS. DAMAGE TO THE BOILER OR SERIOUS PERSONAL INJURY OR DEATH MAY RESULT.
WARNING
DO NOT RE-LIGHT THE PILOT OR ATTEMPT TO START THE MAIN BURNER, EITHER OIL OR GAS, IF THE COMBUSTION CHAMBER IS HOT AND/OR IF GAS OR OIL VAPOR COMBUSTION GASES ARE PRESENT IN THE FURNACE OR FLUE PASSAGES OR WHEN EXCESS OIL HAS ACCUMULATED. PROMPTLY CORRECT ANY CONDITIONS CAUSING LEAKAGE. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
B. EMERGENCY SHUT DOWN
In case of emergency, shut down the burner by turning the On-Off switch to the "OFF" position. Turn the fuel selector switch to the OFF position. Shut off the main manual fuel shut off valves on the fuel supply line. The unit can also be shut down with the main electrical power disconnect. Inspect the burner carefully and trouble shoot before re-starting the unit. Follow instruction in Chapter 3 for starting and operating.

Installation, Operation, and Service Manual
WARNING
ONLY FAC TORY AUTHOR I Z E D BURNER SERVICE PERSONNEL SHOULD START- UP, ADJUST, OR SERVICE THIS EQUIPMENT.
CHAPTER 7
WARNING:
THE F.G.R. SHUTOFF VALVE SHOULD NEVER BE
MOUNTED IN THIS POSITION! THE MODUTROL
MOTOR CAN NOT BE MOUNTED VERTICALLY, (VERTICAL
IS DEFINED BY THE AXIS OF THE MOD. MOTOR SHAFT)
DAMAGE TO THE MODUTROL MOTOR WILL RESULT.
LOW NOx SYSTEM
This section covers the adjustments for the Low NOx burners. The Low NOx burners are equipped with a Flue
Gas Recirculation system (F.G.R.). The ue gases are
duct to the air housing and the burner combustion air fan
is used to pull ue gases from the stack. The F.G.R. rate is
controlled by a damper blade linked to the modutrol motor.
Top or bottom connection is used with a anged adaptor to
the damper box. Fresh air and F.G.R. is mixed and injected in the combustion zone. All F.G.R. duct piping should be covered with a minimum of 2" of insulation and supported as required. The burner is designed to operate with < 30
ppm NOx corrected @ 3% O2 throughout the ring range, when ring natural gas. The following controls are used
for a safe operation of the system.
A. F.G.R. SHUTOFF VALVE. (Figure 7-1)
The F.G.R. shutoff valve is located as close to the stack as
possible. A modutrol motor with a 90 degree stroke opens and closes the F.G.R. shutoff valve in 15 seconds. Proof of closure for the shutoff valve is provided by an auxiliary switch in the modutrol motor. The modutrol motor has a maximum temperature rating of 150°F. This valve should never be mounted with a motor shaft in a vertical position. Damage to the modutrol motor will result. During pre purge and post purge, the F.G.R. shutoff valve is closed to prevent any unused gas fumes from returning to the combustion zone.
B. F.G.R. DAMPER ASSEMBLY (Figure 7-3, 7-4)
The F.G.R. control is mounted to a F.G.R. damper on the burner. A burner mounted modutrol motor with link­age connections, coordinates the air, fuel and NOx control devices to provide proper fuel/air/NOx ratios through the ring range. The modutrol motor must be able to com­plete its full travel range. Restrictions will damage the motor and /or the linkage. Linkage consists of adjustable levers, rods and ball joints that transmits motion from the modutrol motor to the F.G.R. control damper. Lever and rod adjustments should be made with the motor in the
low-re position. The angles of the driven levers on the
modutrol motor jackshaft can be adjusted to vary the rate of change. The closer the rod is to the lever hub, the less distance the rod and control blade will travel. The F.G.R. damper regulates the volume of combus­tion air. Position of the damper blade is controlled by a
modutrol motor. The damper blade in the low re position
is normally almost closed. The F.G.R. damper and F.G.R. control valve blades open as the modutrol motor drives
toward the high re position where ue gas is pulled into the regulated combustion air ow above the damper blade
as controlled by the F.G.R. control valve. Combustion air
mixed with ue gas is passed on through the blast tube to
the combustion zone. Follow the instructions in Chapter 4 for the adjustment procedures.
NOTE
IT IS SUGGESTED THAT ALL F.G.R. PIPING BE SCH #40, 14" I.D., AND BE COVERED WITH A MINIMUM OF 2" OF INSULATION
