Placement & Rigging
Proper placement of your Fulton Product (see Figure 1, and Tables 1 and 2) is
essential. Attention paid to the following points will save a great deal of diculty
in the future. Correct placement is the rst step to trouble-free installation,
operation and maintenance.
Adhere to the following for equipment placement and rigging:
1. Consult authorities with jurisdiction over any national or local codes
(including but not limited to National Fire Protection Agency (NFPA),
American National Standards Institute (ANSI), Underwriters Laboratories
(UL), SCA, and ASME, which might be applicable to boiler applications
before beginning.
2. Make appropriate determinations for placement, based on the following:
§Check building specications and Table 2 for unit weights.
§Ensure the equipment is to be placed on a non-combustible level base
with adequate clearances from combustible materials. See Clearances &
Serviceability section.
§Locate boiler as close as possible to the place where the heat will be used
in order to keep pipe work costs to a minimum.
§Ensure that there is adequate clearance around the unit to provide
access for operators and maintenance personnel to all parts of the
equipment. Ensure also that clearance provides for component removal for
maintenance. See Clearances & Serviceability section. The equipment
should be placed in a suitable boiler house or well ventilated separate
room through which personnel do not normally pass. The layout should
eliminate trac in potentially hazardous areas. For instance, the service
engineer or the operator should not have to pass exposed, hot pipe work
to make adjustments to the boiler controls.
§Ensure the equipment is to be placed in such a way that the electrical
components are protected from exposure to water or excessive humidity.
§Ensure the boiler is located a safe distance from the fuel oil tank (if
applicable).
3. Determine rigging procedure, based on the following:
§Units are shipped and crated for forklift transport. Once uncrated, all units
can be transported with a forklift and/or lifting lugs at the top of the boiler.
All skidded units can be moved with forklifts.
§If means of lifting are not available, place rollers beneath the frame of the

NOTE:´When calculating ventilation requirements, heat losses from the Fulton
equipment (and other equipment) should be considered.
Clearances & Serviceability
Adhere to the following for equipment clearances and serviceability:
1. Ensure appropriate front, back, sides and top clearances are met. This
will allow access around the equipment to facilitate maintenance and a
safe work environment, and ensure technicians will commission the unit.
Technicians will not commence commissioning if hazardous conditions
exist.
2. Place boiler with clearances to unprotected combustible materials,
including plaster or combustible supports, not less than the following:
§Heater Front: 36 in. (914 mm)
§Heater Sides and Rear: 18 in. (457 mm)
§Heater top: 24 in. (610 mm)
§Allow for additional minimum clearances for personnel access and burner
removal, as necessary.
§Verify that all clearances are acceptable with the local ordinances.
Environment, Ventilation and Combustion Air
Requirements
It is critical to provide free access of air to the boiler. To burn fuel properly, it
requires one square inch opening for every 3,000 BTU input of fuel (6.4 cm2 for
every 756 kCal).
Adhere to the following to meet ventilation and combustion air requirements:
1. Install two fresh air openings, one at a low level, 24”(610 mm) from the
oor, and one at a higher level on the equipment room wall. This will
provide a ow of air to exhaust the hot air from the equipment room.
2. Ensure the equipment room air supply openings are kept clear at all times.
! WARNING
All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct, and strict
adherence to applicable jurisdictional/
professional codes and regulations.
Failure to provide required and safe
access to the equipment could impede
commissioning and maintenance.
Service technicians are instructed not to
commence commissioning if hazardous
conditions exist.
Failure to provide proper minimum
clearances between equipment and
combustible materials may result in re.
The installation of an exhaust fan in the
boiler room is not recommended. An
exhaust fan or similar equipment can
create a downdraft in the stack or restrict
the burner’s air supply and result in poor
combustion. It is essential only fresh
air be allowed to enter the combustion
air system. Foreign substances such as
combustible volatiles and lint may create
hazardous conditions.
Ensure all labels on the boiler are legible.
All connections and safety devices, both
mechanical and electrical, must be kept
clean, with ease of access for inspection,
use and maintenance.

4. If positive forced ventilation is adopted, ensure that
there will be no appreciable pressure variation in the
equipment room.
5. Avoid ventilation which creates a negative pressure
in the building as it will seriously aect combustion
and proper operation of the burner. Please note that
exhaust fans or similar equipment can create a down
draft in the chimney or starve the burner’s air supply.
Either case may result in poor combustion or nuisance
failures. A properly designed make-up air system in the
equipment room will preclude these possibilities and is
required to maintain proper combustion.
6. Eliminate potential for high risk situations for particulate
matter to be in the combustion air supply (e.g., as a
result of construction and maintenance activities).
Utilities
¡The Gas Supply
Adhere to the following for gas supply installation:
1. Install gas piping in accordance with all applicable
codes.
2. Ensure pipe and ttings used are new and free of dirt or
other deposits.
3. Ensure piping is of the proper size for adequate gas
supply to the gas head assembly. Consult your gas
company for specic recommendations.
4. When making gas piping joints, use a sealing
compound resistant to the action of liqueed
petroleum gases. Do not use Teon tape on gas line
heads.

for the quantity of oil being delivered to the burner. Vacuum must
not exceed 10 in. (254 mm) of mercury at the pump inlet. Maximum
inlet pressure to oil pump is 3 PSIG.
2. Make fuel connection in accordance with the details on the enclosed
fuel pump cut sheet.
3. Ensure fuel oil piping is in accordance with local/national
requirements.
4. Meet the maximum pressure allowed at the fuel oil pump inlet per
the National Fire Protection Association (NFPA).
5. Oil pumps are of a two-line design system, requiring a return line and
a supply line. The oil pump is factory set per Test Fire Sheet. Do not
alter the setting without consulting the factory.
6. A stop valve, a check valve, and an oil lter must be installed on the
oil supply line.
7. Ensure there are no loose ttings. Loose ttings in the fuel oil line will
permit air to enter the fuel line and cause improper ring.
! WARNING
A qualied installer, service agency or the
gas supplier must perform installation and
service on the fuel delivery system.
Do not use matches, candles, ame or
other sources of ignition to check for gas
leaks.
What to do if you smell gas:
Do not try to light the appliance.
Do not touch any electrical switch.
Do not use any phone in the building.
Leave building and contact gas supplier
from neighbor’s phone. If you cannot
reach gas supplier, phone the re
department.
When making gas piping joints, maintain
proper ventilation to reduce breathing
hazards.
An exhaust fan may draw products of
combustion into the work environment
creating a possible hazard to personnel.
4 CAUTION
It is essential that only fresh air be allowed
to enter the combustion air system. Foreign
substances, such as combustible volatiles
and lint in the combustion system can create
hazardous conditions. If foreign substances
can enter the air stream, the combustion air
inlet must be piped to an outside location.
Failure to do so will void the warranty.
To avoid failures due to poor combustion,
ensure make-up air system is properly
designed.

Water Supply
¡Install Water Piping
All water supplies contain some solids, dissolved gases or dissolved minerals.
These may cause corrosion, deposition and/or fouling of equipment. To prevent
these contaminants from impacting boiler performance, valve operation and
general pipe longevity, each location must be analyzed and treated accordingly.
Adhere to the following for water piping installation:
1. Isolation valves and unions are recommended on both water connections
for ease of service.
2. Install piping so that the boiler is not supporting any additional piping.
3. Install manual purging valves in all loops and zones. Install a pressure-
reducing (automatic ll) valve in the cold water ll line to the boiler system.
Check that the proposed operation of zone valves, zone circulator(s) and
diverting valves will not isolate air separator(s) and/ or expansion tank(s)
from the boiler. Clearance from hot water pipes to combustibles must be at
least 6 inches (152 mm).
4. Pipe the water supply line to the lower opening on the back of the boiler.
Water stop valve should be in line between the boiler and the rst piece
of equipment. Hot water outlet should be piped to process/equipment
requiring hot water. Water makeup supply should be installed. Hot water
inlet should be piped to the make-up water supply.

9. Install corrosion coupon holder to assess corrosion inhibitor performance if
appropriate.
NOTE:´The boiler is provided with a drain valve connection and a drain valve.
10. Heating system:
»An automatic pressure activated water make up valve with back
ow preventer. It must be set to maintain required Net Positive
Suction Head (NPSH) for re-circulating pumps, a positive system
pressure at the highest point of at least 5-10 PSIG, and make up
water valve should be designed to add water to the system at the
outlet of the boiler and should not be fed directly into the boiler.
»Air removal equipment, including an air separator and automatic
breather valves, along with a functioning expansion tank . Each
must be designed to system specications.
11. When used in conjunction with a refrigeration system, install the boiler
so that the chilled medium is piped in parallel with the boiler with
appropriate valves to prevent the chilled medium from entering the
boiler. If the boilers are connected to heating coils (located in air handling
units where they may be exposed to refrigerated air circulation) such
boiler piping systems must be equipped with ow control valves or other
automatic means to prevent gravity circulation of the boiler water during
the cooling cycle.

§Corrosion Inhibitor: Capable of maintaining iron corrosion rates <2
mpy. Due to changing environmental restrictions a non-heavy metal
ALL ORGANIC inhibitor is recommended which is designed for multi
metal systems including ferrous metals and yellow metals such as
copper and brass.
§Chloride: Less than 250 ppm
Adhere to the following:
1. Refer to your water conditioning or chemical treatment supplier for
analysis and recommendations for proper system conditions.
2. Follow a program with appropriate monitoring and maintenance of
system water conditions as provided by your water conditioning or
chemical treatment supplier.
3. Operate the boiler in a closed-loop system using water or water/glycol
(not requiring a make-up water supply). A large amount of improperly
treated make-up water can cause premature failure of the heat
exchanger resulting from scale build up. Scale build up will reduce the
eciency and useful life of the boiler and is not covered under warranty.
¡Prevent Oxygen Contamination
There are several ways to prevent boiler water oxygen contamination:
§Minimize system leaks to minimize make up water requirement
§Do not use open tanks or ttings
§Do not use oxygen permeable materials anywhere in the water
system
§Repair leaks in the system quickly
§Eliminate ttings wherever possible
§Use air elimination devices in system piping
¡Eliminate System Air
NOTE:´There are no built-in boiler air eliminating features.
Adhere to the following for air elimination:
1. The installation of an air separator and air eliminator (air vent) is required.
2. To prevent scale corrosion in boiler and associated piping, make up
water must be kept to a minimum. This is best achieved by ensuring
immediate repair of all leaks and that system pressure is maintained.
3. If a sealed diaphragm-type expansion tank is used, install an air
eliminator in the hot water piping at the air separator.
4. If an air cushion type expansion tank is used, pipe tank directly into

5. On multi-zoned systems (or a system with both space and domestic water
heating), air elimination must be provided either in the common piping or
on every loop.
6. When the boiler is installed at a higher level than baseboard radiation (if
used), air elimination must be provided directly above the unit.
Piping Specifications
For piping, the basic considerations are: the design temperature, the pressure
retained by the pipe, the uid in the pipe, the load resulting from thermal
expansion or contraction, impact or shock loads imparted such as water hammer,
external loads, wind loads and vibration from equipment.
Adhere to the following for piping installation:
1. Ensure the arrangement of the piping and its appurtenances takes into
consideration the location of other structures and equipment adjacent to
the piping, which may result in freezing interference and/or damage as a
result of expansion, contraction, vibration, or other movements.
2. Consider the appropriate location and orientation of valves necessary
for safe operation and isolation of the piping. Valves are used in piping
systems to stop and start the ow of uids, to regulate ow, to prevent the
back ow, and to relieve excessive pressure build up in the piping.
3. Ensure all piping and piping components are suitable for the design
temperatures, pressure and uid used in the system.
4. Ensure all pipework is constructed from seamless mild steel pipe, Schedule
40 or Schedule 80 as required by code and/or application; or copper if
system parameters allow.
5. During construction of the installation, ensure that no dirt, water, or
residue from welding is left in the system.
6. Provide expansion joints or properly designed and sited loops to
accommodate thermal expansion. Thermal expansion should be calculated
using the maximum possible utilization uid temperature, regardless of
whether the pipe considered is in the feed or return circuit. Steel pipe will
expand approximately 1“ per 100’over a 100° F temperature rise (1 mm
per meter over 100 C rise).
7. Provide supports and anchors for all pipes where necessary to prevent
undue stresses from being placed on items of equipment, including
pumps, valves, and the boiler. Supports and anchors which will not
interfere with thermal expansion should be chosen.
8. Cut screw threads carefully and accurately. If possible, new tools should be
used. It is recommended that GR5 or higher tensile steel bolts be used for
all anged joints.
9. Use gaskets to make all anged connections. Gasketing material must be
! WARNING

The vent line connection on the gas
pressure regulator must be piped to
outdoor air by the installer in accordance
with National Fuel Gas Code, ANSI Z223-
1-1991 or latest addenda. In Canada, gas
installations must be in accordance with
the current CAN/CGA B149.1 and 2 and/or
local codes.
4 CAUTION
Some soap used for leak testing is
corrosive to certain types of metals. Use
an appropriate leak test solution. Clean all
piping thoroughly after completing the leak
check.

suitable for use with the pressure, temperatures and uids in the system.
Ensure that all bolts are tightened evenly and to the torque recommended
values provided by the gasket manufacturer.
10. Install high point bleeds at all high points in the system piping. 1/2”x 12”
nipples welded in the top of the piping with ball valves and plugs attached
are to be used.
11. Install all pipes with a pitch to facilitate draining and venting.
Insulation
After the appropriate system tests have been satisfactorily completed (see
Testing section of this manual), all hot pipework and vessels must be adequately
insulated with material suited to the temperature and application to prevent
both heat loss and personnel injury. For inspection and maintenance purposes,
leave pumps, anges, valves and ttings uninsulated but suitably shielded for
safety. Removable insulation may also be used over these components.
System Interfaces
Proper selection and installation of the components in the system will ensure
proper and safe operation of the boiler. Consult Fulton representative or contact
Fulton at [phone].
¡Fill Connection
The system is usually lled from the lowest point, with the aid of a pump. On skid-
mounted units, a ll connection is provided in the inlet piping to the pump.
Pressure Gauges
The range in which readings are expected to fall should comprise mid-scale
on the pressure gauge chosen. Pressure gauges must be able to withstand
overpressure equal to the rating of the safety relief valves, normally 100 psig.
NOTE:´The Water temperature pressure gauge should not be altered in any way.
Assembly of Multi-Skid Systems
Adhere to the following for multi-skid engineered systems:
1. Refer to the Fulton mechanical/electrical drawings during assembly.
2. Ensure that equipment orientation allows for operation interface and
maintenance.
3. Align the skids as shown on the drawings ensuring that skid fasteners (skid
joint angles) are matched. The skid joint angles are a matched set and the
edges of the fasteners should be exactly aligned.

jurisdictional/professional codes and
regulations.
Assure all electrical connections are
powered down prior to attempting
replacement or service of electrical
components or connections of the
equipment.
Cements for plastic pipe should
be kept away from all sources of
ignition. Proper ventilation should
be maintained to reduce the hazard
and to minimize breathing of cement
vapors.
No shuto of any kind may be
placed between the safety relief
valve and the equipment, or in the
discharge pipe between such valve
and the atmosphere. Doing so may
cause accidental explosion from
overpressure.
Discharge from safety relief valve
must be congured so that there
is no danger of scalding personnel
or causing equipment damage.
Provisions must be made to properly
drain safety relief valve discharge
piping.
For reasons of safety, the hot exhaust
gas duct and chimney must be
insulated or shielded within the
locality of the heater in compliance
with local codes and regulations.
4 CAUTION
The stack arrangement and draft
conditions should be in accordance
with the information in this manual for
proper performance of the equipment.
NOTE:´Do not bolt the skids to the housekeeping pad/oor until all of the piping
has been reassembled and tightened.
4. Ensure the skids are level and at before fastening the skids together with
the supplied bolts. The skids should be leveled front to back, side to side
and corner to corner. Failure to properly level the skids will result in piping
misalignment. A level or laser level should be used to verify skid alignment
(when a standard level is used, the length should be appropriate for the
skid). If assembling multi-component support stands, attach sections
using the supplied bolts through the tank frame mounting plates. These
should be hand tight until all of the piping is assembled. Note: skids are
leveled at the factory using a laser level.
5. Connect the piping between the skids by matching the union connections
and/or ange stamps and tightening. Refer to the mechanical drawing
as necessary to conrm location of spool pieces etc. as the ange stamps
are shown on the drawing in hexagonal callouts. The ange stamps
should matched and aligned (the ange stamps should be directly across
from one another. Rotating a ange will result in piping misalignment).
Bolts should be hand tight until all of the piping is assembled. Refer to
the appropriate instructions to tighten the anges to the required torque
specications. Support pipe runs as required.
6. Ensure that a low point drain is installed in the piping.
7. Connect the conduit runs between the skids and tighten conduit
connectors.
8. Locate the supplied wiring for the equipment and pull wiring through
the appropriate conduit runs. Electrical wires are labeled for easy landing.
Connect all wiring per the Fulton supplied electrical drawings.
9. If a header is supplied, mount the header as shown in the mechanical
drawing.
NOTE:´For piping supplied in sections, make up and connect hand tight until all
sections are in place to ensure sections align properly. Sections are match marked
for reassembly.
10. Tighten all connections.
11. Pneumatically test the piping (at 15 psig maximum) prior to lling the
systems.
12. Check bolts and connections for tightness after the rst heat up cycle.
Retorquing may be required.
Stack and Flue
An appropriately sized stack should be connected to the ue gas outlet at the
boiler. The proper ue size and draft control is most important for proper burner
operation. See Table 4.
Stack and chimney must be constructed from material that is rated for 1000 F

operating temperature. Check all local codes for requirements.
The ue must be as large or larger than the outlet on the vessel. Avoid ue
piping and elbows by placing the equipment as close as possible to the chimney.

100 14 (356)
130 14 (356)
150 16 (406)
Adhere to the following for stack and ue installation (see Figure 2):
1. Ensure the stack rises continuously to the connection at the chimney and
contains no more than two bends at 45 degree angles or less. If required,
as a result of space limitations, one 90 degree elbow (or tee) can be tted
at the back of the vessel.
2. Ensure 2 feet (0.6 m) of straight, horizontal ue before any change in
direction, tting or draft regulator. This is to prevent potential pilot or
main ame failures due to back pressure build up during ignition. Any
alternative stack arrangement must supply negative 0.02 to 0.04”wc.
3. Ensure 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, does
not exceed 25% of the rise. With the exception of the duct run previously
described, horizontal sections of ducting must be avoided and should not
exceed 4 feet (1.2 m) total. See Figure 2.
4. Ensure the stack, chimney, and any components associated with the stack,
such as heat reclaimers or assist fans, are constructed from material that is
rated for a 1000 F (538 C) operating temperature.
5. Ensure the stack and chimney material complies with all applicable codes.
6. Make adequate provisions for the support of the weight of the chimney
and stack to avoid having a load imparted to the outlet connection of the
equipment.
7. Ensure the draft, when ring, is negative and constant. A reading of -0.02
to -0.04”wc (-0.508 to -1.016 mm) when the unit and stack are cold usually
indicates sucient draft. When the unit is running and the stack is hot, the
draft should read -0.04 to -0.08“wc (-1.016 to -1.524 mm) negative.
8. The installation of a draft regulator by the client/contractor is
recommended at all installations. This will help to maintain the required
draft. The placement of the draft regulator should be as shown in Figure 3.
Insulate the section of the chimney duct within the building.
