This manual is provided as a guide to the correct operation and
maintenance of your Fulton Gas Fired Steam Boiler, and should be
permanently available to the staff responsible for the operation of
the gas fired boiler.
These instructions must not be considered as a complete code of
practice, nor should they replace existing codes or standards which
may be applicable.
The requirements and instructions contained in this section
generally relate to the standard Fulton Gas Fired Steam Boiler.
When installing a packaged unit, this entire section should be read
to ensure that the installation work is carried out correctly.
Prior to shipment the following tests are made to assure the
customer the highest standards of manufacturing:
a) Material inspections.
b)Manufacturing process inspections.
c)ASME welding inspections.
d)ASME hydrostatic test inspection.
e)Electrical components inspection.
f)Operating test.
g) Final Engineering Inspection
h)Crating inspection.
All units are crated for fork lift transport. Once uncrated, all units can
be transported with a forklift. Under no circumstances should weight
be allowed to bear on the jacket, control panel, or fan housing of any
Fulton Boiler.
Rigging your boiler into position should be handled by a competent
rigger experienced in handling heavy equipment.
The customer should examine the boiler for any damage, especially
the refractories. It is the responsibility of the installer to ensure
all parts supplied with the boiler are fitted in a correct and safe
manner.
NOTE
The installation of the Fulton Gas Fired Steam Boiler should
be carried out by competent personnel in accordance with the
standards of the National Fire Protection Association, National
or Canadian Electrical Code. All state and jurisdictional codes
beyond the scope of the applicable ASME Boiler and Pressure
Vessel Codes, for its corresponding classification, should be
followed in all cases. Jurisdictional authorities must be
consulted prior to installation.
WARNING
Operating the boiler beyond its design limits can damage the
boiler and can also be dangerous. Do not operate the boiler
outside its limits. Do not try to upgrade the boiler performance
by unapproved modifications. Unapproved modifications can
cause injury and damage. Contact your Fulton dealer before
modifying the boiler.
WARNING
A defective boiler can injure you or others. Do not operate a
boiler which is defective or has missing parts. Make sure that
all maintenance procedures are completed before using the
boiler. Do not attempt repairs or any other maintenance work
you do not understand. Obtain a Service Manual from Fulton
or call a Fulton Service Engineer.
- Do not store or use gasoline or other flammable vapors and liquids in the vicinity of
this or any other appliances.
- WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electrical switch; do not use any phone in your building.
• Immediately call your gas supplier from a neighbor’s phone. Follow the gas
supplier’s instructions.
• If you cannot reach your gas supplier, call the fire department.
- Installation and service must be performed by a qualified installer, service agency
or the gas supplier.
WARNING: If the information in this manual is not followed exactly, a fire or
explosion may result causing property damage, personal injury or loss of life.

Safety Warnings and Precautions
For Your Safety
The following WARNINGS, CAUTIONS, and NOTES appear in various sections of this manual.
They are repeated on these safety summary pages as an example and for emphasis.
WARNINGS must be observed to prevent serious injury, or death to personnel.
CAUTIONS must be observed to prevent damage or destruction of equipment or loss of operating effectiveness.
NOTES must be observed for essential and effective operating procedures, conditions, and as a statement to be highlighted.
It is the responsibility and duty of all personnel involved in the operating and maintenance of this equipment to fully understand the
WARNINGS, CAUTIONS, and NOTES by which hazards are to be eliminated or reduced. Personnel must become familiar with all
aspects of safety and equipment prior to operation or maintenance of the equipment.
WARNING
Care should be taken to ensure that the blow off receptacle
used meets the regulations covering such vessels. A means to
cool boiler blowdown water to <140
o
F prior to discharging to
floor drains is required for personnel and equipment
protection.
WARNING
Only properly trained personnel should install and maintain
water gauge glass and connections. Wear safety glasses
during installation. Before installing, make sure all parts are
free of chips and debris. Gauge glass valves must be fully
open to prevent boiler water damage if a gauge glass breaks.
WARNING
Prior to the commencement of any work requiring the removal
of cover plates and the opening of the control panel box, the
electrical supply to the boiler must be disconnected.
WARNING
DO NOT TAMPER WITH THE SAFETY FEATURES OF THE
LOW WATER SAFETY CUT OFF.
WARNING
When shutting down the boiler for any extensive repairs, shut
off main disconnect switches on both the boiler and the feed
water pump.
WARNING
Do not clean the gauge glass while pressurized. Ensure gauge
glass valves are fully shut prior to glass removal.
WARNING
Do not allow anyone to operate, service or repair this
equipment unless they fully understand all applicable sections
of this manual.
CAUTION
To prevent corrosion fatigue at the feedwater nozzle or
cold end corrosion, boiler feed water must be at least
140
o
F prior to entry into the boiler.
CAUTION
A temperature exceeding 100oF in the boiler room may
cause premature failure of electrical components in the
boiler control panel.
CAUTION
The water chemistry in the boiler must be kept within
limits outlined in this manual. Failure to do so will likely
cause premature boiler pressure vessel failure and poor
steam quality.
NOTE
After installation is complete and prior to operation the
pressure vessel should be cleaned or boiled out per
instructions included in this manual.
NOTE
a) The fused disconnect switch that controls the feed water
pump should be kept in the “on” position at all times during
the boiler operation as well as during the non-operating
period of the boiler.
b) This switch should be turned “off” only when repairs or
adjustments should be made.
NOTE
The feedwater pump will continue to operate until the water
reaches the correct level in the boiler. This level is
approximately the center of the water gauge glass.
NOTE
To ensure that your Fulton Steam Boiler is kept operating
safely and efficiently, follow the maintenance procedures set
forth in Section 4 of this manual.
NOTE
If only the top refractory is to be changed, the bottom
refractory need not be removed.
NOTE
The boiler blow off operation should be done once during the
day when the boiler is at 10 PSIG or less.
NOTE
After a new Fulton Boiler has been in operation for several
months, pieces of burned metal will be found in the space at
the bottom of the boiler. These pieces of metal are the remains
of a light gauge metal form which was used during
manufacture for forming the boiler insulation. This is a normal
condition and does not affect the efficiency or the life of the
boiler in any way.

The Gas Supply
a. Gas Piping should be installed in
accordance with National Fuel Gas
Code, ANSI-Z223-1-1984 or latest
addenda and any other local codes
which may apply. In Canada gas
installations must be in accordance with
the current CAN/CGA B149.1 and .2
and/or local codes.
b. Install a dirt trap ahead of all of the gas
valves.
c. The pipe and the fittings used must be
new and free of dirt or other deposits.
d. The piping must be of the proper size to
ensure adequate gas supply to the gas
head assembly. Consult your gas
company for specific recommendations.
e. 7” - 11” wc gas pressure is required
during run for 40-60 HP boilers with
standard burners. 9”-11” wc gas
pressure is required during run for 80
100 HP boilers with standard CSD-1
burners, 11”-13” wc gas pressure is
required for 80-100 HP IRI boilers. 40”
W.C. is required for 130-150 HP
f. For propane or butane gas: see “e”
above. Propane not available for LoNOx
boilers.
g. When making gas piping joints, use a
sealing compound resistant to the action
of liquefied petroleum gases. Do not use
teflon tape on gas line threads.
h. The main and the pilot gas pressure
regulators must be vented to the
atmosphere.
i. After gas piping is completed carefully
check all piping connections, (factory
and field), for gas leaks. Use a soap and
water solution.
CAUTION
Some soaps used for leak testing are
corrosive to certain types of metals.
Rinse all piping thoroughly with clean
water after leak check has been
completed.
j. The boiler must be disconnected at the
boiler shut off valve from the gas supply
piping system during any pressure
testing of the system at pressure in
excess of 1/2 PSIG-14" W.C.
k. The boiler must be isolated from the gas
supply piping system by closing the
shut-off cock during any pressure
testing of the gas supply piping system
at pressures equal to or less than 1/2
PSIG--14" W.C.
Installation
Page 22
Installation
For units equipped with Flue Gas
Recirculation (FGR), the ducting must
be insulated.
WARNING
CAUTION
Do not exceed the rated pressure of
the fuel train.
The Gas Supply
For LE Models
A minimum of 40” w.c. gas pressure is
required at the inlet of the gas train while
operating for the 40-100HP; 60” w.c. for
the 130-150HP boiler.
Basic Boiler, Condensate
Tank, and Blow-Down
Separator
NOTE
Where a condensate return tank is to be
fitted:
1. This should be vented to a safe
location.
2. This should have a capacity sufficient
to satisfy boiler consumption as well
as maintain proper return tank
temperature.
3. Vent pipe should not be down-sized
(this may cause pressure build up in
the condensate tank).
4. Return pipes must not be insulated.
This can cause overheating the
return system, causing a vapor lock
in the pump.
5. See Return System Instruction
Manual for detailed instructions.
NOTE
Care should be taken to ensure that the
blow-down receptacle used meets the
regulations covering such vessels. If in
doubt consult a Fulton Representative
for advice.
VMP IOM

VMP IOM
a. Make sure two check valves are
installed between the boiler and pump
(one check valve is supplied with the
unit).
b. In a closed system an end of the line
trap should be installed.
c. There are four blow-down valves on the
boiler: Two main bottom blow-down
valves, the gauge glass blow-down
valve, and the water column blow-down
valve. All blow-down connections must
be piped to blow-down seperator.
All these procedures should be done in
accordance with state and/or local codes.
The water column blow-down valve and the
gauge glass blow-down valve should be
connected to the main blow-down line.
Steam Supply
Pipe the steam supply line from the top right
side of the boiler.
Steam Safety Valve
1. Before installing, be sure that all pipes
and connections have been blown
clean. Pipe compound or dope is used
on external threads only. Be sure inlet of
valve is free of any foreign material.
2. Do not use a pipe wrench! When
making installation, use proper type and
size wrench.
3. The valve should be installed in a
vertical upright position in the
connection provided on the top left side
of the boiler with no unnecessary
intervening pipe. Under no
circumstances should there be a shut off
valve or restriction of any kind between
the safety valve and the connection
provided.
4. Do not cap or plug drain hole in the side
of valve body.
5. Since the purpose of this safety valve is
to protect against an overpressure
situation, it will loudly discharge hot
steam in doing so. Therefore, it is
recommended that a discharge pipe be
securely installed and run to a safe point
of disposal.
6. When a discharge pipe is used, it must
be of a pipe size equal to or greater than
that of the valve outlet. Use schedule 40
discharge pipe only. Do not use
schedule 80, extra strong or double
extra strong discharge pipe or
connections. It must be as short and
straight as possible and so arranged as
to avoid undue stress on the valve. It
must have an ample provision for
draining condensate at or near the valve
outlet. It must terminate freely to
atmosphere with no intervening valve of
any description and it must be securely
anchored and supported.
Steam Pressure Gauge
Assembly
The gauge should be facing front towards
the panel box and/or operator of the boiler.
Except as noted, each assembly or any of
its component parts may be oriented, other
than as shown to provide improved
operating clearances and/or view of gauge.
Before installing steam gauge on the
siphon, add a small amount of water to the
siphon to create a water seal to buffer the
gauge element. This must be done to
prevent inaccurate pressure readings and
/or premature failure of the gauge. Install
the steam gauge into the siphon on the
water column.

Blow-Down Valve
There are four blow-down valves on the
boiler: Two main bottom blow-down valves,
the gauge glass blow-down valve, and the
water column blow-down valve. All blowdown connections must be piped to blowdown seperator.
Feed Water Piping
1. Provisions must be made for adequate
water supply and properly sized piping.

2. When feeding the boiler using a return
system, the city water pressure should
not exceed 40 PSI. A pressure reducing
valve should be installed a head of the
return tank when above this pressure.
3. It is important that all piping be lined up
and not forced into place. It is
recommended that you begin piping at
the pump. If the lines are ended at the
pump, particularly if the last piece is cut
too short or long, the pump will be forced
to meet the pipe and strain or distortion
will result.
4. Do not use the pump as a piping
support. It is critical that the pipe be
independently supported near the pump
so no strain will be transmitted to the
unit.
5. Connect the feed water stop valve to the
feed water pipe at the rear of the boiler
and pipe it to the return system.
Water Column
Install the piping from the water column and
water gauge glass to a safe blow-down point.

Water Gauge and Gauge
Glass Installation
Instructions
NOTE
Only properly trained personnel should
install and maintain water gauge glass
and connections. Wear safety glasses
during installation. Before installing,
make sure all parts are free of chips and
debris.
NOTE
Keep gauge glass in original packaging
until ready to install.
1. Verify the proper gauge has been
supplied.
2. Examine the gauge glass and packings
carefully for damage before installation.
Do not use the glass if it contains any
scratches, chips, or any other visible
signs of damage.
3. Do not subject the gauge glass to
bending or torsional stresses.
4. Apply teflon tape or pipe dope to pipe
threads. Install top gauge fitting (fitting
without a drain valve) into the
uppermost tapping. Wrench tighten the
fitting until it is snug and the glass outlet
is pointing at five o’clock (about 1/8 turn
from its final downward vertical
position).
5. Install the bottom gauge fitting (the fitting
with a drain valve) until it is snug and the
glass outlet is pointing directly upward.
Verify top and bottom fittings are
threaded into the tappings the same
number of turns (distance A=distance
B).
6. Remove glass packing nut, friction
washer and glass packing from the
fittings, and place them, in the same
order, on to both ends of the gauge
glass. Push both packings about an inch
up the gauge glass.
7. Gently insert one end of the glass into
the top gauge fitting. Keeping the glass
inside the top fitting, gently rotate the top
gauge fitting clockwise until vertically
aligned with the bottom gauge fitting,
then inset glass into bottom fitting until
glass bottoms out on the shoulder inside
the bottom fitting.
8. Carefully raise glass about 1/16” and
slide lower glass packing down until the
glass packing contacts the lower gauge
fitting. DO NOT allow the glass to
remain in contact with any metal!
9. Carefully slide upper glass packing up
as far as possible.
10.Hand tighten both glass packing nuts,
then tighten 1/2 turn more by wrench.
Tighten only enough to prevent leakage.
DO NOT OVER TIGHTEN! If any
leakage should occur, tighten slightly, a
quarter turn at a time, checking for
leakage after each turn.
11.Install the protective guard, and utilize
automatic ball checks where necessary
to help prevent injury in case of glass
breakage.
WARNING
Improper installation or maintenance of
gauge glass and connections can cause
immediate or delayed breakage resulting
in bodily injury and/or property damage.

Water Supply
Feed water contains solids and dissolved
gases. These may promote formation of
scale; foaming, priming, surging, and solids
in steam; corrosion and pitting; or caustic
embrittlement. To prevent this, feedwater
must be studied individually and treated
accordingly by reputable professionals
specializing in this field. It is strongly
recommended that a competent water
treatment company be consulted prior to
the installation of the boiler.
The purpose of this treatment should be to
provide quality feedwater to the boiler such
that corrosion and deposition in the boiler
will be minimized. Dissolved oxygen, high
TDS levels and low pH can all be major
causes of corrosion. Untreated hardness is
the major cause of scale deposits. Poor
quality feedwater will require increased
blow-down and increased chemical
treatment costs to prevent boiler corrosion
and scaling.
One way to lower the amount of dissolved
oxygen in the boiler feed water is the
feedwater preheating option. This option
injects live steam into the feedwater to
increase the water temperature to at least
180 degrees F (82 degrees C) which
removes oxygen from the water.
TDS can be controlled by increasing the
number and/or duration of blow downs per
day from one to four.
The Fulton Warranty does not cover
damage or failure that can be attributed
to corrosion, scale or sludge
accumulations. Oxygen is corrosive. See
the Warranty Section of this manual for full
details.
Recommended Water

corrosion and/or deposits from forming.
Glossary of Water Supply
Corrosives and Inhibitors
DISSOLVED OXYGEN
Oxygen that is dissolved in the feedwater
will cause the steel in the boiler and the
feedwater system to be attacked by the
water in a manner described as “pitting”.
The pits that are produced can vary from
tiny depressions to holes large enough to
penetrate the boiler metal and are usually
covered with tubercles of iron oxide. Once
pitting starts, it may be extremely hard to
arrest. Pitting can proceed at a surprisingly
rapid rate and can occur not only in the
boiler proper, but also in pre-boiler
equipment such as economizers, feedwater
heaters, and feedwater lines.
SUSPENDED SOLIDS
Suspended solids are the undissolved
matter in water, including dirt, silt, rust and
any other insoluble matter. Normally
suspended solids are expressed in terms of
turbidity.The presence of suspended solids
in cooling water can increase impingement
type corrosion. Suspended solids may also
deposit in low velocity areas and create
differential aeration cells. Pitting can result.
The most common cause of high
suspended solids is high hardness
feedwater piping corrosion and inadequate
blow-down rate.
In line filters, or various types of
pretreatment can be used to lower the
suspended solids level. Various polymers
assist in holding solids in suspension. Boiler
blow-down is the best way to control
suspended solids.
ALKALINITY
Alkalinity is the capacity of a water to
neutralize acids. Common water alkalinities
consist of bicarbonate, carbonates,
hydroxide, phosphate, and silicate. These
alkalinities, especially bicarbonates and
carbonates, break down to form carbon
dioxide in steam, which is a major factor in
the corrosion on condensate lines. High
alkalinity also causes foaming and carry
over in boilers.
Both foaming and carry over cause erratic
boiler operation. When foaming occurs an
anti-foam should be added or increased.
The reason for the high alkalinity should be
determined. It may result from lack of
sufficient blow-down. Pretreated makeup
water and condensate should also be
checked. quite often the source of alkalinity
is an overdose of alkaline internal water
treatment chemical.
pH
pH is a measure of the degree of acid or
base of solution. Neutral pH ranges of 6.5-
7.5 will have negative influence on the
corrosion rate of carbon steel. A low pH can
result in corrosion of metals, while a high
pH can result in scale formation. Optimal
boiler pH is 9-11, slightly alkaline
In order to control boilers and equipment
used for the external treatment of make up
water, it is essential that frequent reliable
pH measurements be made.
Installation

CHLORIDES/CHLORINE
Chlorides are generally considered
detrimental in stainless steel systems only.
Stress corrosion cracking can occur from
high chlorides.
High chlorine levels can cause severe
corrosion. Corrosion from chlorine can be
controlled by removal via carbon filtration.
City water can contain high levels of
chlorine.
OIL
Oil is not a natural constituent of boiler
water; still it can frequently enter a system
through leaks in a condenser or other heat
exchanger. Oil can also enter a system
through the lubrication of steam driven
reciprocating equipment. Whatever the
source, the presence of oil in boiler water is
undesirable.
Foaming is one indication of oil in boiler
water. Its presence can also be confirmed
by first shaking a bottle containing boiler
water. If oil is present foam will result. To
ensure the foaming is being caused by oil,
add a small amount of powdered activated
carbon to the bottle containing the boiler
water and shake. Little or no foam will
appear if the foaming is caused by oil.
Often oil in boiler water will originate in the
condensate. This contaminated condensate
should be directed to the sewer until the
source of the oil is determined and corrective
steps taken. Boiler and boiler system piping
boil out procedure are designed to rid a
system of oil contamination.
IRON (OXIDES)
Iron in any of its oxide or complex forms is
undesirable in boiler water. It is very difficult
to disperse so that it can be removed the
bottom blow-down lines.
Iron in its various forms can originate in the
raw water makeup, condensate return water,
or form directly in the boiler as a result of
corrosion. Most iron oxide originates outside
the boiler. It concentrates in the boiler and it
tends to collect in stagnant areas. If a boiler
is using raw water makeup, iron is almost
certain to be a major component of
developing scale or sludge deposits.
WATER HARDNESS
Water hardness is the measure of
calcium and magnesium content as
calcium carbonate equivalents. Water
hardness is a primary source of scale in
boiler equipment. Hardness is removed
by water softeners or RO/DI systems. It
can also be treated with various
chemical treatments (i.e. Phosphates).
FEEDWATER
Feedwater is the combination of fresh
makeup and returning condensate that is
pumped to the boiler. Hot (>180°F)
feedwater, free of hardness, solids and
oxygen will yield the most protection to a
boiler.
CONDENSATE
Condensate is condensed steam that is
normally low in dissolved solids. Hence, it
does not contribute to the dissolved solid
content of the feedwater. In addition,
condensate is very expensive to waste. It's
been chemically treated, heated, pumped,
converted to steam, and condensed. This
costs money and when condensate is
returned to the boiler, money is saved.

Electrical Requirements
1. Connect wiring as shown in the wiring
diagram which is furnished inside the
electrical control panel box.
2. Be sure to install a separate disconnect
for each piece of equipment. The
disconnects should be installed in
compliance with the NEC (National
Electric Code) and all local codes.
3. Connections for an optional audible
alarm are provided in the control panel
and are clearly indicated on the diagram.
Fresh Air Supply
for Boiler
It is most important to provide free access of
air to the boiler. To burn fuel properly, it
requires one square inch opening of fresh air
for every 3,000 BTU input of fuel. (6.4cm
2
for
every 756 Kcal).
Proper ventilation of the boiler room is
essential for good combustion. Install twofresh air openings, one at a low level 24”
(610 mm) from floor and one at a higher
level in the boiler room wall.This will provide
a flow of air to exhaust the hot air from the
boiler room. Boiler room temp not to
exceed 100°F.
The following openings are recommended for
each size boiler:

150242.23
Be sure total BHP = proper make up air
opening size.
These measurements are subject to state
and local regulations. The installation of
exhaust fans in a boiler room is not
recommended.
An exhaust fan, or similar equipment can
create down draft in the stack or restrict the
burner’s air supply which will result In poor
combustion. It is essential that only fresh air
is allowed to enter the combustion air
system. Foreign substances, such as
combustible volatiles and lint, in the
combustion system can create hazardous
conditions.
Conventional Venting
The stack should rise continuously to the
connection with the chimney, and should
contain no more than two bends at 45°
angles or less. If required as the result of
space limitations, one 90° elbow can be
fitted at the back of the boiler. There should
be two feet of straight, horizontal flue before
any bends or turns. Any alternative stack
arrangement must supply a negative .02 .04” W.C. pressure (0.508 to 1.016 mm)
with the burner off.
The run in the total distance of stack ducting,
as measured in a straight line from the outlet
of the boiler to the outlet of the stack, should
not exceed 70% of the rise. With the
exception of a duct run described in Item a,
horizontal sections of ducting must be
avoided, and should not exceed four feet of
total run.
The stack and chimney must be
constructed from material that is rated for
1000°F operating temperature. Check all
local codes for exact requirements.
Adequate provision must be made for the
support of the weight of the chimney and
stack to avoid having too great a load
imparted to the flue outlet connection of the
boiler.
The proper flue size and draft control is
most important for proper burner operation.
The flue must be
as large or larger than the outlet on the
boiler. Avoid flue piping and elbows by
placing the boiler as close as possible to the
chimney.
A mechanical draft regulator should be
installed in the flue outlet. Do not install the
draft regu-lator prior to the first turn of the
flue.

Corrosion of flue pipe
In the case of a combustion flue pipe, acid
may develop over a long period of time per
the following process. Chlorine containing
gases, such as halocarbon refrigerants,
carbon tetrachloride, trichloroethylene, or
perchloroethylene, when drawn into
combustion air are broken down into
elemental chlorine gas which exits up the
flue pipe. If the flue pipe is cold, as it would
be if the combustion process had been off
for some time, the water vapor condenses
in the flue pipe during the first few minutes
of ignition and the chlorine in the
combustion gas dissolves in the water
forming hydrochloric acid. As the
combustion system flue line increases in
temperature, the water vapor no longer
condenses because the flue temperature is
above the dew point of the combustion gas.
The combustion gas then dries out
(dehydrates) the hydrochloric acid solution
leaving behind dry chloride salt.
When the next cold start-up occurs, the
process repeats except that more and more
chloride collects and concentrates along
the flue. As the quantity of chloride
increases it does not dehydrate completely
as the flue heats up and a corrosive poultice
develops which attacks the steel and will
also attack the boiler.
Concentration levels of only a
few ppm of chlorine containing compounds
in combustion air can produce serious
corrosion over long periods of time. High
chlorine containing compounds such as
carbon tetrachloride or perchloroethylene
would be prime suspects.
In addition, normal combustion creates
carbon dioxide which may condense in a
cold flue to form carbonic acid.
Installation Check Points
1. Make sure all piping connections are
complete and tight.
2. Make sure the pressure controls are
adjusted properly.
3. Make sure all electrical connections in
the control panel box, the water column,
and elsewhere are secure.
4. Make sure the door in the boiler room is
closed. Combustion air contaminates
can cause damage to the boiler jacket
and stack.
NOTE
After installation is complete and prior
to operation the pressure vessel should
be cleaned.

After the boiler has been installed and
before it is placed in service it is advisable
to purge the pressure vessel of any oil
film,dirt, or other impurities. Clean the
pressure vessel as follows:
1. Isolate the boiler from the system by
shutting off the main steam valve.
2. Remove the steam safety valve.
3. Mix washing soda with water in a onegallon container and pour it into the
boiler through the steam safety valve
opening.
4. The mixture of washing soda to water is
as follows:
7. Generate 15 PSI (1.054 kg/cm
steam and shut off the boiler. Allow this
hot solution to remain in the boiler for 10
minutes.
8. Drain and flush the boiler twice with
fresh water.
9.To remove all the oil and dirt from the
main steam and the condensate return
lines, allow the returns to go into a floor
drain or a safe discharge point for the
first week of operation.

Primary Air Adjustment
for Fulton Gas Fired
Steam Boilers
1. The primary air adjustment or main air
control is located at the fan housing
face. This control is used to supply the
burner with excess air needed to
facilitate good combustion. Too much or
too little air will result in poor
combustion. It is important to make sure
the lowest level of excess oxygen is
present while still maintaining a high
level of carbon dioxide and negligible
carbon monoxide. Using a CO
2
or O
2
tester it is possible to determine the
percent of excess air in the combustion
mixture.
2. It is a good policy on a gas fired unit to
have between 3.5% and 4% oxygen
present in the combustion. This will give
you 10.5% to 9.5% carbon dioxide. The
carbon monoxide level should always
be less than 400 PPM.
Secondary Air Adjustment
Procedure for Fulton Gas
Fired Steam Boilers
1. The secondary air control adjustment is
located on the top, right-hand side of the
burner assembly. This damper type air
controller is used to introduce air to and
through the blast tube of the burner. The
purpose of the secondary air adjustment
is to proportionately divide the air to the
center or outer fire chamber. By moving
the damper closed, the air is forced to
the outside of the fire chamber with less
air going down the blast tube area. By
pulling the damper open more air is
forced down the blast tube and less on
the outside wall of the deflector face and
fire chamber.
2. It is important in the combustion process
to maintain proper air mixtures between
the outer surface and center of the blast
tube area. On most boilers the damper
is locked in a wide open position.
However, if it is necessary to close the
damper, care should be taken to close
the damper slowly and no more than
1
/4
of the distance of the swing of the
damper assembly.
3. A visual examination down the blast
tube should reveal that no heat, flames
or fumes are backing up through the
burner plate area. If they are, the
secondary damper must be opened up
once again. Failure to remove the flame
or gases from the blast tube area can
cause a backfire as well as cause
premature failure of electrodes, flame
rods, and other burner components.
4. A visual inspection down the burner
view port should also show the fire
completely covering the furnace walls. If
the fire is tunneling down or is not to the
outside wall of the furnace, the efficiency
will drop off. Close the secondary air
damper until tunneling stops.

Operation
Boiler Controls
a. Flame safeguard burner control
This is the main control in the panel box.
The programmer in conjunction with a
sensing device, either a flame rod or an
ultra violet scanner, "supervises" the
ignition sequence - proves the flame is
satisfactory - and finally "monitors" the
established flame. Should any fault
occur, either during the ignition
sequence or during normal running, the
programmer will immediately go to
"lock-out" and the burner will shut down.
b. Low Water Cut-Off - Probe Type
Cuts off the unit when water level is too
low after a 3 second time delay to avoid
nuisance shut downs. As a standard
feature, Fulton boilers are equipped with
ASME CSD-1 Code controls which
include a manual reset feature on the
burner low water cut off relay and ASME
CSD-1 Code controls also feature an
independent second low water cut off
relay. Press the low water reset button
and the boiler will start.
CAUTION
Do not tamper with the safety features of
the low water safety cut out.
c. Pressure Relief Valve
Limits the maximum operating pressure
of the boiler.
d. Operating Steam Pressure Control
Located in the control panel box and
connected to the steam pressure gauge
assembly by means of a copper tube.
The pressure control regulates the
on/off cycle of the burner, shutting the
burner off when maximum pressure is
reached and switching on when the
steam pressure falls below a
predetermined level.
e. Sight Glass Isolation Valves
The brass sight glass isolation valves
are equipped with an internal ball check.
In the event that a sight glass should
break, the ball will seat, preventing the
discharge of steam and water. The
brass valve stem must be opened fully
to enable this feature. If the valve is in
any other position than full open, the ball
will not seat. For added safety all Fulton
boilers are equipped with gauge glass
protectors.
f. High Limit Pressure Control
Located in the control panel box and
connected to the water column
assembly by means of a copper tube.
The pressure is usually set 10 to 15 PSI
(.703 - 1.054 kg/cm
2
) above the
operating pressure, but below the
maximum pressure of the pressure
relief valve. If the pressure exceeds the
high limit pressure control setting, the
boiler will automatically shut off. The
high limit pressure control must be
manually reset by depressing the
plunger located on top of the control.
g. Air Pressure Switch
Mounted on the burner scroll, this switch
is operated by the pressure of air
entering the burner through the throat of
the scroll. Absence of air, or insufficient
pressure, will prevent the switch
completing the circuit, thus preventing
the burner from operating.
WARNING
When stopping the boiler for any
extensive repairs, shut off main
disconnect switches on both the boiler
side as well as the feed water side.
NOTE
To ensure that your Fulton Steam Boiler
is kept operating safely and efficiently,
follow the maintenance procedures set
forth in Section 4 of this manual.

Air and Gas Adjustment
for LE Models
The low emission burner can be best
described as a fuel staged, multi-radial
injection type. Two air/gas ratio electro
servo actuators control the fuel supplied to
this burner. A radial blade type fan supplies
the air. A direct-coupled reversing actuator
modulates the air which in turn regulates
the fuel input. No mechanical linkage is
utilized with this system. As a safety device,
a thermocouple is placed in the small partial
premix area of the burner to monitor
temperature. It is used in conjunction with a
temperature limit that should be set
between 600° and 700°F.

BEFORE LEAVING THE INSTALLATION
Check all controls to insure they are
operating properly. Cycle the boiler several
times. Make sure the installation complies
with all applicable codes.
NOTE
Decreasing the primary will typically
decrease the NOx levels. If the primary
is decreased too much, stability may be
compromised.
a. Start the boiler and check for stable
combustion at low fire. Refer to the test
fire sheet for acceptable parameters.
b. Adjust secondary servo air/gas if
needed to bring combustion into an
acceptable range. Adjust carefully as
this is the main fuel adjustment.
c. After a stable flame is achieved and the
combustion is within the test fire sheet
parameters, manually and slowly drive
the servo’s motor to high fire insuring
that the combustion readings stay within
the given parameters. Adjust secondary
servo as needed.
d. If the last elbow pressure is above or
below the stated requirement on the test
fire sheet, adjust the combustion air
damper to bring the last elbow pressure
inline. The gas pressure is directly
proportional to the air pressure and
therefore, increasing the air pressure to
the burner will increase the gas input
proportionally.
e. Manually drive the unit back to low fire
and check combustion.
f. If the combustion is outside of the test
fire parameters for the servo, adjust the
secondary.
g. After the unit is brought back into range,
manually drive the unit back to high fire.
h. Adjust secondary air/gas ratio slightly if
needed.
i. Repeat this procedure 2 or 3 times until
you obtain consistency in high and low
fire combustion.
j. In most cases, the primary gas should
only be adjusted if the unit is unstabe at
low fire and/or NOx are not acceptable
at low fire.
Operation
Page 40

CAUTION
During startup insure that adequate gas
pressure is supplied to the main valves.
The indicator on the actuator should
never reach the bottom of the indicator
window. In the event that this happens,
adjustability will be lost. See minimum
incoming gas pressure requirement on
the test fire sheet. The SKP10 actuator
functions only as on/off. When
activated, the indicator will reach the
bottom of the indication window. The
main gas pressure regulator is only
used to comply with standard
regulations and therefore uses a high
outlet pressure spring that is set at the
max. The SKP70 fuel valves have a built
in regulator function.

to improve the signal.
3. If the scanner is found to be
defective, replace.
NOTE
The scanner is located on the outside
edge of the burner top plate for 40, 80,
and 100 HP.
4. For the RM7800 Series use a keyboard
display module or volt meter. The flame
safeguard will require a 1.25 VDC
signal to pull in the main flame. Then a
maximum signal should be obtained on
main flame (5.0 VDC).

breakage and inspect the stainless
steel ring (50-100 HP only).
g. With the boiler under no more than 15
PSI pressure, check that the steam
safety valve is operating by lifting the
lever.
2. Drain condensate tank and clean tank
by flushing with hose. Check float valve
operation.
3. Check electrical controls and motors for
correct operation.
4. Check water pump for correct operation.
5. Shut off the boiler completely and drain.
6. Remove the hand holes and inspect the
interior of the vessel for scale or sludge
deposits. The amount of deposits will
indicate the efficiency of the water
treatment being used. The frequency of
the inspection will depend on the
condition of the water side of the boiler.
7. Replace hand hole gaskets using the
following procedure:
a. Remove the hand hole assembly
using a 1

b. Remove the old gasket and
thoroughly clean the surface on the
boiler and the plate.
c. Fit the hand hole assembly as follows:
i. Place the gasket on the hand hole
plate and ensure that it is seating
correctly. Do not use any grease,
lubricant, or adh esive.
ii. Position the plate in the boiler. Set
the yoke and tighten the securing nut
sufficiently enough to provide a snug
fit. Verify the position of the plate in
the boiler, then make it hand tight and
then snug with wrench about
1
/4 turn.
Do not compress excessively.
Illustration shows correct pressure on
gasket.
iii. If the gasket leaks while pressure
is being built up, tighten only enough
to stop leakage. Never tighten more
than necessary to prevent leakage.
Excessive tightening may shorten the
life of the gasket.
Illustration shows over-compressed
gasket.
d. Refill the boiler with fresh water.
NOTE
After a new Fulton Boiler has been in
operation for several months, pieces of
burned metal will be found in the space
at the bottom of the boiler. These pieces
of metal are the remains of a light gauge
metal form which was used during
manufacture for forming the boiler
insulation. This is a normal condition
and does not affect the efficiency or the
life of the boiler in any way.
Recommended Annual
Maintenance Schedule
1. Have combustion (CO2, O2, CO) and
input checked by responsible personnel.
2. Dirty flues can cause air flow restrictions
resulting in poor combustion and loss of
efficiency. Clean flues as follows:
a. Remove the outer flue cover plate.
b. Remove inner plate and turbultors.
c. Remove clean out plugs at lowest
part of unit and clean the bottom of
combustion chamber.
d. Remove all soot from the top, and
from the clean out plugs at the bottom
with a vacuum cleaner.
e. Replace clean out plugs carefully so
as not to damage insulation and
replace burner and flue cover plates.
3. Flush boiler out if necessary. See
Section 2 for proper procedure for
"Cleaning the Pressure Vessel."
4. Provide annual inspection by a qualified
ASME Boiler inspector.
Troubleshooting
The following trouble shooting guide will
assist in the diagnosis and the correction of
minor field problems. It contains instructions
and information necessary to locate and
isolate possible troubles which occur during
normal operation. It should be used in
conjunction with the unit wiring diagram and
the component literature provided in
Section 7 of this manual.
The following lists cover the most common
troubles that may occur on the Fulton gas
fired boilers. Refer to left hand column of
the chart to locate the problem. Determine
which cause, listed in the center column,
that represents the problem by performing
the corrective action as listed in the right
hand column titled “REMEDY”.
With the burner on and the boiler under pressure, lower the set pressure on the switch until it
trips and shuts down the burner. Ensure the pressure that the switch trips at is the same as the
boiler operating pressure.
To test the manual reset button, wait until the boiler has fully completed the post purge phase.
Once the boiler is in the standby position, reset the switch to the original set point.
Press the manual reset switch on the pressuretrol. This will ensure that the manual reset switch is
functioning correctly. The burner should not start until the reset button is pressed.
Operating Pressure Limit Switch:
With the boiler under pressure, lower the set pressure on the switch until it trips and shuts down
the burner. Be sure that the pressure that the switch trips at is the same as the boiler operating
pressure.
This switch is an auto reset.
Reset the switch to the original set point. The burner should turn back on automatically.
Flame Scanner:
Verify that the flame scanner is observing flame with the burner running.
Turn boiler to the off position.
NOTE
o Do not shut off gas supply with boiler operation. This can lead to a potentially dangerous
situation.
Close both the main gas supply isolation valve and gas pilot line isolation valve.
Turn the boiler to the on position. The boiler will proceed through the ignition sequence. Once
burner control completes the ignition sequence, the burner control should display fault code for
pilot flame failure.
During the pilot sequence, burner control should not display any flame signal during scanner test
with gas valves turned to the off position. If flame signal is present, troubleshooting will be
required to identify cause of the spark pickup.
Turn the boiler to the off position and open the gas pilot line isolation valve while leaving the
main gas isolation valve in the closed position. This will allow for the burner to cycle through
the pilot sequence and test main flame failure. The burner control should display fault code for
main flame failure. Turn the boiler off after this test is complete.
o Typically on boilers 30 HP and below, the pilot flame will be sufficient to allow the
boiler to cycle through the main flame test. If this occurs, slowly shut the pilot line
isolation valve. This will cause the boiler to fail on main flame.
Once the boiler has completed the post purge cycle, turn the boiler to the off position. Open the
main gas supply valve, turn the boiler to the on position and resume normal operation.

Low Water Cutoffs:
Definition: Each cutoff device shall be installed to prevent startup and to cut off the boiler fuel or
energy supply automatically, prior to the fall of the water level below the lowest visible part of the
gauge glass.
Standard low water cutoff is Fulton level probes. Alternate cutoffs are MM-63, MM-150, MM-157,
MM-193-7b, etc. All cutoffs are tested in the same manner as described below.
When testing the low water cutoff devices, it is important that the boiler feed pump is turned off to
allow for proper draining. Remember to turn the pumps back on when level cutoff testing is
complete.
Testing of Low Water Cutoff Controls:
Your Fulton steam boiler is equipped with two automatic Low-Water Cut-Off (LWCO) controls. Each
LWCO will prevent startup and cut off the boiler fuel or energy supply automatically when the surface
of the water falls to a level not lower than the lowest visible part of the gage glass. One control is set to
function ahead of the other. The standard Fulton LWCO control utilizes a water level probe and
incorporates a 3 seconds time delay to prevent short cycling. Optional float type LWCO controls may
also be used on the boiler.
The LWCO controls can be tested by lowering the water in the boiler. The test should be done with zero
steam pressure in the boiler, or not more than 10 PSI.
Shut off the make-up water supply to the boiler.
Open the blow-down valve at the back of the boiler to allow the water level to slowly drop until ¾” and
1” of water level is visible sight glass and close the blow down valve. The first LWCO control will drop
out within 3 seconds and cut off the boiler fuel or energy supply. This LWCO control is typically
configured to automatically reset when the adequate water level in the boiler is restored. Some local
jurisdictions require this LWCO control to be a manual reset.
Open the blow-down valve at the back of the boiler to allow the water level to slowly drop until 1/8” to
1/4” of water level is visible sight glass and close the blow down valve. The second LWCO control will
drop out within 3 seconds and cut off the boiler fuel or energy supply. This LWCO control is
configured for manual reset. When the adequate water level in the boiler is restored you have to
momentarily press the LWCO manual reset button to enable operation of the boiler.
Air Switch:
To test the air switch, first turn the boiler to the off position.
Once the boiler is off, remove the air supply from the air switch and turn on the boiler. Once the
boiler is in the purge process, the safety interlock should appear and shut down the burner.
Turn the burner off and reattach the air switch air supply.
Reset the flame programmer.
Cycle the boiler multiple times to be sure that no nuisance faults occur.
Page 51
Low Gas Pressure Switch:
Bring boiler to high fire (100% firing rate)
Increase the dial on the low gas pressure switch until it trips and locks out the boiler
Make note of the pressure that the burner shuts down at
Once the gas switch trips, set the pressure switch to 50% lower than the value that the switch
tripped at – Example: gas switch trips at 10 in. w.c., set the switch to 5 in. w.c.
Reset the switch and flame programmer
Cycle the burner and observe for proper operation
High Gas Pressure Switch:
Bring boiler to low fire (0% firing rate)
Decrease the dial on the high gas pressure switch until it trips and locks out the boiler
Make note of the pressure that the burner shuts down at
Once the switch trips, set the pressure switch to 50% higher than the value that the switch tripped
at – Example: gas switch trips at 10 in. w.c., set the switch to 15 in. w.c.
Reset the switch and flame programmer
Cycle the burner and observe for proper operation
Proof of Closure:
Disconnect power to the boiler
While the boiler is off, remove the common wire to the proof of closure switch and install a wire
nut on the end of switch or wrap in tape to properly protect the wire.
Turn power to the boiler back on
The boiler should immediately lock out on alarm due to the POC being disconnected.
Disconnect power and reconnect the POC wire
Turn power to the boiler back on and reset any flame programmer faults
Cycle the burner and observe for proper operation
Flashback Protection:
Locate the flashback protection device and change the setting to the lowest setting. This is
typically 32 deg. F.
o To change the setting, the “Set/Reset” button must be pressed as the wheel is rotated
The device will generate an alarm
Reset the device to the factory temperature setting. This is typically 750 deg. F for standard
steam units.
Try to turn on the burner. It should not work as the reset button on the control has not yet been
pressed.
Press the reset button on the controller. The boiler should now operate correctly.
