WARNING
Appliance materials of construction, products of combustion and the fuel contain alumina, silica,
heavy metals, carbon monoxide, nitrogen oxides, aldehydes and/or other toxic or harmful
substances which can cause death or serious injury and which are known to the state of California
to cause cancer, birth defects and other reproductive harm. Always use proper safety clothing,
respirato r s and equipment when servicing or working nearby the appliance.
This boiler co ntains very hot water u nder high pressures. Do not unscrew any pipe fitting s nor
attempt to disconnect any comp onents of this boil er without positively assuring the water is cool
and has no pressure. A lways w ear protective clothing and equipment when installing, starting
up or servicing this boiler to prevent scald injuries. Do not rely on the pressure and temperature
gauges to determine the temperature and pressure o f the boiler. This boiler contains components
w hich become very hot w hen the boiler is operating. Do not touch any components unless they
are cool.
This appliance must be properly vented and connected to an approved vent system in good
condition. Do not ope rate boiler with the absence of an unapproved vent system.
This boiler needs fresh air for safe operation and must be installed so there are provisions for
adeq uate combustion and ventilation air.
The interior of the venting and air intake systems m u st b e inspected and cleaned before the start
of the heating season and should be inspected periodically throughout the heating season for
any obstructions. Clean and unobstructed venting and air intake systems are necessary to allow
noxious fum es that could cause injury or loss of life to vent safely and will con tribute toward
maintaining th e boiler's efficiency.
This boiler is supplied with controls which may cause the boiler to shut down and not re-start
withou t service. If dam age du e to frozen pipe s is a pos sibility, the hea ting system s hould
not be left u n atttended in cold weather; or appropriate safeguards and alarms should be installed
on the heating system to prevent dam age if the boiler is inoperative.
This boiler is designed to bu rn No. 2 fuel oil only. D o not use gasoline, crankcase drainings, or
any oil containing gasoline. Never burn garbage o r paper in this boiler. Do not convert to any
solid fuel (i. e. wo o d, co al) or gaseous fuel (i. e. natural g as, LP/propane). All flammable d ebris,
rags, paper, wood scraps, etc., should be kept clear of the boiler at all times. Keep the boiler area
clean and free of fire hazards.
Do not operate boiler on combustible floor without a factory supplied floor shield. Concrete over

I. Pre-Installation
A. INSPECT SHIPMENT carefully for any signs of
damage.
1. ALL EQUIPMENT is carefully manufactured,
inspected and packed. Our responsibility ceases
upon delivery of the crated boiler to the carrier in
good condition.
2. ANY CLAIMS for damage or shortage of shipment
must filed immediately against the carrier by the
consignee. No claims for variances from, or
shortage in orders, will be allowed by the manufacturer unless presented within sixty (60) days after
receipt of goods.
B. LOCATE BOILER in front of final position before
removing crate.
1. LOCATE so that smoke pipe connection to chimney will be short and direct. BOILER IS NOT
SUITABLE FOR INSTALLATION ON COMBUSTIBLE FLOOR unless combustible floor shield,
supplied by Burnham, is used. DO NOT install on
carpeting.
2. FOR BASEMENT INSTALLATION, provide a
solid base, such as concrete, if floor is not level, or
if water may be encountered on floor around boiler.
3. PROVIDE SERVICE CLEARANCE of at least 48”
from the front of the jacket for servicing of burner
and removal of tankless heater.
For minimum clearances to combustible materials. See
Figure 2.
Figure 2: Minimum Clearances to Combustible Materials
NOTE:
1.Listed clearances comply with American National Standard ANSI/NFPA 31, Installation of Oil Burning Equipment.
2.RSA boilers can be installed in rooms with clearances from combustible material as listed above. Listed clearances can not
be reduced for alcove or closet installations.
3.For reduced clearances to combustible material, protection must be provided as described in the above ANSI/NFPA 31
standard.
7
C. PROVIDE AIR SUPPLY AND VENTILATION to
accommodate proper combustion. If natural ventilation is inadequate, provide a screened opening or duct
from the boiler room to the outside. The opening or
duct must be sized so the boiler input will not exceed
4,000 BTUH/Sq. In. of free area. If other air consuming appliances are near the boiler, the air inlet should
be larger. Consult respective manufacturers.
D. VENTILATION AIR must be provided to maintain
the ambient temperature at safe limits. Local and
national codes may apply and should be referenced.
1. In unconfined spaces (basement) in buildings of
conventional frame, brick, or stone construction,
infiltration normally is adequate to provide air for
ventilation.
2. In confined spaces, two permanent openings, one
near the top of the enclosure and one near the
bottom, shall be provided. Each opening shall have
a free area of not less than 1 sq. inch per 1000
BTUH of the total input of all appliances in the
space.
3. PROVIDE COMBUSTION AND VENTILATION
AIR. Local code provisions may apply and should be
referenced.
than 50 ft3/1000 BTU per hour then the space is
considered a confined space.
D. For boiler located in an unconfined space of a conven-
tionally constructed building, the fresh air infiltration
through cracks around windows and doors normally
provides adequate air for combustion and ventilation.
E. For boiler located in a confined space or an unconfined
space in a building of unusually tight construction,
provide outdoor air with the use of two permanent
openings which communicate directly or by duct with
the outdoors or spaces (crawl or attic) freely communicating with the outdoors. Locate one opening within 12
inches of top of space. Locate remaining opening
within 12 inches of bottom of space. Minimum
dimension of air opening is 3 inches. Size each
opening per following:
1. Direct communication with outdoors. Minimum
free area of 1 square inch per 4,000 BTU per hour
input of all equipment in space.
2. Vertical ducts. Minimum free area of 1 square
inch per 4,000 BTU per hour input of all equipment in space. Duct cross-sectional area shall be
same as opening free area.
3. Horizontal ducts. Minimum free area of 1 square
inch per 2,000 BTU per hour input of all equipment in space. Duct cross-sectional area shall be
same as opening free area.
Alternate method for boiler located within confined
space. Use indoor air if two permanent openings
communicate directly with additional space(s) of
sufficient volume such that combined volume of all
spaces meet criteria for unconfined space. Size each
opening for minimum free area of 1 square inch per
1,000 BTU per hour input of all equipment in spaces,
but not less than 100 square inches.
A. Determine volume of space (boiler room). Rooms
communicating directly with the space in which the
appliances are installed, through openings not furnished with doors, are considered a part of the space.
Volume(ft3) = Length(ft) x Width(ft) x Height(ft)
B. Determine total input of all appliances in the space.
Add inputs of all appliances in the space and round the
result to the nearest 1000 BTU per hour.
C. Determine type of space. Divide Volume by total input
of all appliances in space. If the result is greater than
or equal to 50 ft3/1000 BTU per hour, then it is
considered an unconfined space. If the result is less
F. Louvers and Grilles of Ventilation Ducts
1.All outside openings should be screened and
louvered. Screens used should not be smaller than
1/4 inch mesh. Louvers will prevent the entrance of
rain and snow.
2.Free area requirements need to consider the
blocking effect of louvers, grilles, or screens
protecting the openings. If the free area of the
louver or grille is not known, assume wood louvers
have 20-25 percent free area and metal louvers and
grilles have 60-75 percent free area.
3.Louvers and grilles must be fixed in the open
position, or interlocked with the equipment to open
automatically during equipment operation.

III. Water Piping and Trim
WAR N I NG
Failure to properly pipe boiler may result in improper ope ration and dam age to boiler or
structur e .
Oxyg en contam ination of boi le r wa t e r will c a use c orrosion of iron a nd steel bo iler
c ompone nts, and can lead to boiler failure. Burnh am's Standard Warranty does no t cover
problems caused by oxygen contamination of boiler water or scale (lime) build-up c aused
by freque nt a ddition of water.
A. Design a piping system and install boiler which will
prevent oxygen contamination of boiler water and
frequent water additions.
1. There are many possible causes of oxygen contamination such as:
a. Addition of excessive make-up water as a result
of system leaks.
b. Absorption through open tanks and fittings.
c. Oxygen permeable materials in the distribution
system.
2. In order to insure long product life, oxygen sources
should be eliminated. This can be accomplished by
taking the following measures:
a. Repairing system leaks to eliminate the need for
addition of make-up water.
b. Eliminating open tanks from the system.
c. Eliminating and/or repairing fittings which
allow oxygen absorption.
d. Use of non-permeable materials in the distribu-
tion system.
e. Isolating the boiler from the system water by
installing a heat exchanger.
WARN ING
System supply and return piping must
be conn ected to corr ect boiler pipe.
Burnham recommends sizing the
s ystem circulator to su pply sufficient
flow (GPM) to allow a 20°F temper ature
diff eren tial i n the s ys tem . When s izing
the system circu lator, the pressur e
drop of all radiators, baseboard and
radiant tubing and a ll connecting
piping must be considered.
3. Connect System supply and return piping to boiler.
See Figures 8 and 9. Also, consult I=B=R Installation and Piping Guides. Maintain minimum ½
inch clearance from hot water piping to combustible materials.
a. If this boiler is used in connection with refrig-
eration systems, the boiler must be installed so
that the chilled medium is piped in parallel with
the heating boiler using appropriate valves to
prevent the chilled medium from entering the
boiler. See Figure 7. Also, consult I=B=R
Installation and Piping Guides.
b. If this boiler is connected to heating coils
located in air handling units where they may be
exposed to refrigerated air, the boiler piping
must be equipped with flow control valves to
prevent gravity circulation of boiler water
during the operation of the cooling system.
c. If boiler is used with an Alliance™ Indirect-
Fired Domestic Water Heater, install the
Alliance™ as a separate heating zone. Refer to
the Alliance™ Installation, Operating, and
Service Instructions for additional information.
d. Use a system bypass if the boiler is to be
operated in a system which has a large volume
or excessive radiation where low boiler water
temperatures may be encountered (i.e. converted
gravity circulation system, etc.) The bypass
should be the same size as the supply and
return lines with valves located in the bypass
and return line as illustrated in Figure 10 in
order to regulate water flow for maintenance of
higher boiler water temperature. Set the bypass
and return valves to a half throttle position to
start. Operate boiler until the system water
temperature reaches its normal operating range.
Adjust the valves to maintain 180°F to 200°F
boiler water temperature and greater the 120°F
return temperature. Adjust both valves simultaneously. Closing the boiler return valve while
opening the bypass valve will raise the boiler
return temperature. Opening the boiler return
valve while closing the by-pass valve will lower
the boiler return temperature.
e. A water boiler installed above radiation level
must be provided with a low water cutoff device
as part of the installation.
12
Figure 7: Recommended Piping for Combination Heating and Cooling (Refrigeration) System
B. Install Pressure Relief Valve. See Figures 8 and 9.
Pressure Relief Valve must be installed with spindle in
the vertical position. Installation of the relief valve
must be consistent with ANSI/ASME Boiler and
Pressure Vessel Code, Section IV.
C. Install Drain Valve in return piping. See Figures 8
and 9.
D. Oil, grease, and other foreign materials which accumu-
late in new hot water and a new or reworked system
should be boiled out, and then thoroughly flushed. A
qualified water treatment chemical specialist should be
consulted for recommendations regarding appropriate
chemical compounds and concentrations which are
compatible with local environmental regulations.
E. After the boiler and system have been cleaned and
flushed, and before refilling the entire system add
appropriate water treatment chemicals, if necessary, to
bring the pH between 7 and 11.

F. CONNECT TANKLESS HEATER PIPING AS
SHOWN IN FIGURE 11. See Table 1 for Tankless
Heater Rating.
WAR N I NG
In stall autom atic mixing valve at tankl ess
heater outlet to avoid risk of burns or
scalding due to excessive ly hot water at
fixtures. Adjus t and m aintain the mixing
valve in accor dance wi th the ma nufa cturer's
instructions. Do not operate tankless
heater without mixing valve.
THE FOLLOWING GUIDELINES SHOULD BE
FOLLOWED WHEN PIPING THE TANKLESS HEATER:
1. FLOW REGULATION — If flow through the
heater is greater than its rating, the supply of
adequate hot water may not be able to keep up with
the demand. For this reason a flow regulator
matching the heater rating should be installed in
the cold water line to the heater. The flow regulator
should preferably be located below the inlet to the
heater and a minimum of 3’ away from the inlet so
that the regulator is not subjected to excess temperatures that may occur during “off” periods when
it is possible for heat to be conducted back through
the supply line. The flow regulator also limits the
flow of supply water regardless of inlet pressure
variations in the range of 20 to 125 psi.
2. TEMPERING OF HOT WATER — Installation of
an automatic mixing valve will lengthen the
delivery of the available hot water by mixing some
cold water with the hot. This prevents the possibility of scalding hot water at the fixtures. In addition,
savings of hot water will be achieved since the user
will not waste as much hot water while seeking a
water temperature. Higher temperature hot water
required by dishwashers and automatic washers is
possible by piping the hot water from the heater
prior to entering the mixing valve. The mixing
valve should be “trapped” by installing it below the
cold water inlet to heater to prevent lime formation
in the valve. Refer to Figure 11.
3. FLUSHING OF HEATER — All water contains
some sediment which settles on the inside of the
coil. Consequently, the heater should be periodically backwashed. This is accomplished by installing hose bibs as illustrated and allowing water at
city pressure to run into hose bib A, through the
heater, and out hose bib B until the discharge is
clear. The tees in which the hose bibs are located
should be the same size as heater connections to
minimize pressure drop.
4. HARD WATER — A water analysis is necessary
to determine the hardness of your potable water.
This is applicable to some city water and particularly to well water. An appropriate water softener
should be installed based on the analysis and
dealer’s recommendation. This is not only beneficial to the tankless heater but to piping and fixtures
plus the many other benefits derived from soft
water.

IV. Venting
A. General Guidelines.
1. Vent system installation must be in accordance with
these instructions and applicable provisions of local
building codes. Contact local building or fire
officials about restrictions and installation inspection in your area.
2. The RSA Series is designed to be vented into a
fireclay tile-lined masonry chimney or chimney
constructed from type-L vent or a factory built
chimney that complies with the type HT requirements of UL103. The chimney or vent pipe shall
have a sufficient draft at all times, to assure safe
proper operation of the boiler. See Figure 12 for
recommended installation.
a. Install a draft regulator (supplied by installer)
following the instructions furnished with the
regulator. See Figure 13 for alternate regulator
locations.
b. With any new or replacement installation the
chimney has to be considered. Chimneys that
have a high heat loss become less suitable as the
heat loss of the home goes down and the
efficiency of the boiler goes up. Most homes
have a chimney appropriate for the fuel and the
era in which the home was built. That may
have been a coal fired or an inefficient oil fired
boiler built into a home without insulation or
storm windows. With increasing fuel prices that
home probably has been insulated and fitted
with storm windows so that the heat loss of the
home has been reduced. This requires less fuel
to be burned and sends less heat up the chimney.
A new boiler probably has a higher efficiency
than the boiler being replaced. That probably
means that the stack temperature from the new
boiler will be lower than that from the old boiler
and with less room air being drawn up the
chimney to dilute the stack gases. The combination of a large uninsulated chimney, reduced
firing rate, reduced firing time, lower stack
temperature and less dilution air can, in some
cases, contribute to the condensing of small
amounts of water vapor in the chimney. Such
condensation, when it occurs, can cause chimney deterioration. In extreme cases, the chimney may have to be lined to insulate the chimney
and thus prevent the condensation. The
addition of dilution air into the chimney may
assist in drying the chimney interior surfaces.
A massive chimney on a cold, or exposed
outside wall may have produced adequate draft
when it was fired with a higher input and
greater volumes of heated gases. With reduced
input and volume, the draft may be severely
affected. In one instance our research showed a
new chimney of adequate sizing produced only .035” W.C. after 30 minutes of continuous firing
at 13.0% CO2. Outside wall chimneys take
longer to heat up and can have .00” W.C. draft
at burner start-up. You may have to consider a
special alloy chimney flue liner with insulation
around it and stabilizing draft cap or even a
draft inducing fan in severe cases.
c. For the same reasons as in (2.) above, heat
extractors mounted into the breeching are not
recommended.
3. For minimum clearances to combustible materials
refer to Figure 2.

VII. System Start-Up
A. Verify that the venting, water piping, oil piping, and
electrical system are installed properly. Refer to
installation instructions contained in this manual.
B. Confirm all electrical, water and oil supplies are turned
off at the source and that the vent is clear from
obstructions.
C. Fill entire heating system with water and vent air from
system. Use the following procedure on a Series Loop
or multi-zoned system installed as per Figure 8 or 9.
1. Close isolation valve in boiler supply piping.
2. Isolate all circuits by closing zone valves or
balancing valves.
3. Attach a hose to bib cock located just below
isolation valve in boiler supply piping. (Note Terminate hose at a suitable floor drain or outdoor
area).
10. Open isolation valve in boiler supply piping.
11. Remove hose from bib cock.
D. CONFIRM that the boiler and system have no water
leaks.
E. CHECK CONTROLS, WIRING AND BURNER to be
sure that all connections are tight and burner is rigid.
Verify that all electrical connections have been
completed, fuses installed, that the oil tank is filled and
oil lines have been tested.
F. LUBRICATION. Follow instruction on burner and
circulator label to lubricate, if oil lubricated. Most
motors currently used on residential type burners
employ permanently lubricated bearings and thus do
not require any field lubrication. Water lubricated
circulators do not need field lubrication.
G. SET CONTROLS with burner service switch turned
“OFF”.
1. SET ROOM THERMOSTAT about 10° above
room temperature.
2. PRESS RED RESET BUTTON on R4184D Oil
Primary Control and release.
4. Starting with one circuit at a time, open zone valve
or valve.
5. Open bib cock.
6. Open fill valve (Make-up water line should be
located directly after isolation valve in boiler supply
piping between air scoop and expansion tank).
7. Allow water to flow into drain until discharge from
hose is bubble free for 30 seconds.
8. When zone is completely purged of air, close zone
valve or balancing valve. Open the zone valve for
the next zone to be purged. Repeat this step until
all zones have been purged. At completion, open
all zone valves or valves.
9. Close bib cock, continue filling the system until the
pressure gauge reads 12 psig. Close fill valve.
(Note - If make-up water line is equipped with
pressure reducing valve, system will automatically
fill to 12 psig.
3. SET HIGH LIMIT dial on L8124C/L8148A at
temperature to suit requirements of installation.
H. REMOVE GUN ASSEMBLY
1. Check nozzle size, head size, gun setting, and
positioning of electrodes. This information is
shown in Figure 23, and Tables 4 and 4A.
2. Reinstall gun assembly.
I.VERIFY OIL BURNER SETTINGS BEFORE
STARTING
1. BURNER AIR BAND AND AIR SHUTTER
SETTINGS, see Tables 4 and 4A.
2. OPEN ALL OIL LINE VALVES.
3. Attach a plastic hose to fuel pump vent fitting and
provide a container to catch the oil.
4. REMOVE GAUGE PORT PLUG from fuel pump
and install pressure gauge.
J. START OIL BURNER
1. Open vent fitting on fuel pump.
2. TURN ‘ON’ BURNER service switch and allow
burner to run until oil flows from vent fitting in a

3. Close vent fitting and burner flame should start
immediately.
4. If the burner does not start immediately, check the
manual overload switch on the motor, if so
equipped, and the safety switch on the burner
primary control.
K. ADJUST OIL PRESSURE
1. Locate oil pressure adjusting screw and turn
screw until Pressure Gauge reads the correct
pump pressure required for the specific boiler.
Refer to table 4 & 4A.
2. DO NOT REMOVE PRESSURE GAUGE until
later.
L. OTHER ADJUSTMENTS
1. ADJUST THE AIR BAND AND/OR AIR SHUTTER.
Beckett Burners:
a. Adjust air supply by loosening lock screws and
moving the air shutter and if necessary the air
band. Refer to Table 4 and 4A preliminary
settings.
2. ADJUST DRAFT REGULATOR for a draft of
-.02” (water gauge) over the fire after chimney has
reached operating temperature and while burner is
running.
3. READJUST AIR BANDS on burner for a light
orange colored flame while draft over the fire is
-.02” w.c. Use a smoke test and adjust air for
minimum smoke (not to exceed #1) with a minimum of excess air. Make final check using suitable
31
Figure 23: Electrode / Head Setting
instrumentation to obtain a CO2 of 11.5 to 12.5%
with draft of -.02” w.c. in fire box. These settings
will assure a safe and efficient operating condition.
If the flame appears stringy instead of a solid flame,
try another nozzle of the same type. Flame should
be solid and compact. After all adjustments have
been made, recheck for a draft of -.02” w.c. over the
fire.
4. TURN “OFF” BURNER and remove pressure
gauge. Install gauge port plug and tighten. Start
burner again.
M. FLAME FAILURE
The RSA boiler controls operate the burner automatically. If for unknown reasons the burner ceases to fire
and the rest button on the primary control has tripped,
the burner has experienced ignition failure. Before
pressing the rest button, call your serviceman immediately.
N. CHECK FOR CLEAN CUT OFF OF BURNER
1. AIR IN THE OIL LINE between fuel unit and
nozzle will compress when burner is on and will
expand when burner stops, causing oil to squirt
from nozzle at low pressure as burner slows down
and causing nozzle to drip after burner stops.
Usually cycling the burner operation about 5 to 10
times will rid oil line of this air.
(Non-Burnham Drawing
Copy from other Manual)
2. IF NOZZLE CONTINUES TO DRIP, repeat step
N.1. If this does not stop the dripping, remove cut
off valve and seat, and wipe both with a clean cloth
until clean. Then replace and readjust oil pressure.
If dripping or after burn persist replace fuel pump.
O. HINTS ON COMBUSTION
a. NOZZLES— Although the nozzle is a relatively
inexpensive device, its function is critical to the
successful operation of the oil burner. The
selection of the nozzle supplied with the RSA
boiler is the result of extensive testing to obtain
the best flame shape and efficient combustion.
Other brands of the same spray angle and spray
pattern may be used but may not perform at the
expected level of CO2 and smoke. Nozzles are
delicate and should protected from dirt and
abuse. Nozzles are mass produced and can vary
from sample to sample. For all of those reasons
a spare nozzle is a desirable item for a serviceman to carry.
b. FLAME SHAPE — Looking into the combus-
tion chamber through the flame plug hole, the
flame should appear straight with no sparklers
rolling up toward the top of the chamber. If the
flame drags to the right or left, sends sparklers
upward or makes wet spots on the combustion
chamber, the nozzle should be replaced. If the
condition persists look for fuel leaks, air leaks,
water or dirt in the fuel as described below.
c. FUEL LEAKS— Any fuel leak between the
pump and the nozzle will be detrimental to good
combustion results. Look for wet surfaces in the
air tube, under the ignitor, and around the air
inlet. Any such leaks should be repaired as they
may cause erratic burning of the fuel and in the
32
extreme case may become a fire hazard.
d. AIR LEAKS— Any such leaks should be
repaired, as they may cause erratic burning of
the fuel and in extreme cases may become a fire
hazard.
There may be many possible causes of leaks in
oil lines such as:
i.Fitting leaks due to misflared tubing or
damaged fitting.
ii. Fuel line leak due to crushed or bent tubing.
iii. Filter connection leaks.
iv. Tank connection leaks.
The following actions can eliminate air leaks:
i.Bleed pump as detailed in System Start-Up
Section of this manual.
ii. Replace flare fittings.
iii. Replace oil supply line.
iv. Repair oil filter leaks
v.Replace or repair tank fittings.
e. GASKET LEAKS— If 11.5% to 12.5% CO
with a #1 smoke cannot be obtained in stack,
look for air leaks around the canopy seal. Such
air leaks will cause a lower CO2 reading in the
stack. The smaller the firing rate the greater
effect an air leak can have on CO2 readings.
f. DIRT— A fuel filter is a good investment.
Accidental accumulation of dirt in the fuel
system can clog the nozzle strainer and produce
a poor spray pattern from the nozzle.
g. WATER— Water in the fuel, in large amounts,
will stall the fuel pump. Water in the fuel
pump, in smaller amounts, will cause excessive
wear on the pump, but more importantly water
does not burn. It chills the flame, causes smoke,
and allows unburned fuel to pass through the
combustion chamber and clog the flueways of
the boiler.
h. COLD OIL— If the oil temperature approach-
ing the fuel pump is 40°F or lower, poor
combustion or delayed ignition may result. Cold

oil is harder to atomize at the nozzle. Thus, the
spray droplets get larger and the flame shape
gets longer. An outside fuel tank that is above
grade or has fuel lines buried in the ground
above the frost line is a good candidate for cold
oil. The best solution is to place the tank and oil
lines in the ground below the frost line.
i. HIGH ALTITUDE INSTALLATIONS
Typically, the rule to use for high altitudes is to
increase the air supply by 4% per each 1000 ft.
above 2000 ft. altitude from sea level. This
means that the air setting will have to be higher
than the calibration marks in proportion to the
altitude. Use instruments and set for 11.5 to
12.5% CO2.
j. START-UP NOISE — Late ignition is the cause
of start-up noises. If it occurs recheck for
electrode settings, flame shape, air or water in
the fuel lines.
k. SHUT DOWN NOISE — If the flame runs out
of air before it runs out of fuel, an after burn
with noise may occur. That may be the result of
a faulty cut-off valve in the fuel pump, or it may
be air trapped in the nozzle line. It may take
several firing cycles for that air to be fully
vented through the nozzle. Water in the fuel or
poor flame shape can also cause shut down
noises.
P. TEST CONTROLS
1. CHECK THERMOSTAT OPERATION. Raise and
lower thermostat setting as required to start and
stop burner.
2. VERIFY PRIMARY CONTROL SAFETY FEATURES using procedures outlined in Instructions
furnished with control (See back of Control Cover)
or Instructions as follows:
33
a. Simulate flame failure:
•Follow the starting procedure to turn on the
burner.
•Close the hand valve in the oil supply line.
•Safety switch should lock out in approxi-
mately 15 seconds. Ignition should stop
and oil valve should close. Blower will stop
after postpurge period.
•Push red reset button to reset safety switch.
b. Simulate ignition failure:
•Follow the starting procedure to turn on the
burner, but do not open the oil supply hand
valve.
•Safety switch should lock out in approxi-
mately 15 seconds. Ignition and motor
should stop and oil valve should close.
•Push red reset button to reset safety switch.
c. Simulate power failure:
•Follow the starting procedure to turn on the
burner.
•With the burner running, turn off the power
to the system by tripping the circuit breaker
or removing the fuse.
•Burner should stop.
•Restore power. Burner should start.
3. VERIFY HIGH LIMIT OPERATION.
a. Adjust thermostat to highest setting.
b. Observe temperature gauge. When temperature
is indicated, adjust limit to setting below
observed temperature. Burner should stop.
c. Adjust limit to setting above observed tempera-
ture. Burner should start.
4. CHECK LOW WATER CUTOFF (if so equipped).
a. Adjust thermostat to highest setting.
b. With boiler operating, open drain valve and
slowly drain boiler.
c. Burner should stop when water level drops
below low water cutoff probe. Verify limit,
thermostat or other controls have not shut off
boiler.
d. Adjust thermostat to lowest setting. Refill
boiler.
Q. Boiler is now ready to be put into service.
A leaky system will increase the volume of make-up
water supplied to the boiler which can significantly
shorten the life of the boiler. Entrained in make-up
water are dissolved minerals and oxygen. When the
fresh, cool make-up water is heated in the boiler the
minerals fall out as sediment and the oxygen escapes
as a gas. Both can result in reduced boiler life. The
accumulation of sediment can eventually isolate the
water from contacting the steel. When this happens
the steel in that area gets extremely hot and eventually
cracks. The presence of free oxygen in the boiler
creates a corrosive atmosphere which, if the concentration becomes high enough, can corrode the steel
through from the inside. Since neither of these failure
types are the result of a manufacturing defect the
warranty does not apply. Clearly it is in everyone’s
best interest to prevent this type of failure. The
maintenance of system integrity is the best method to
achieve this.
d. Adjust thermostat to lowest setting. Adjust limit
to desired setting.
