INSTALLATIONEDR-IOM-2014-0318 SECTION 2
! 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.
The discharge from the safety relief
valve must be arranged to ensure
no danger of scalding personnel, or
equipment damage.
Provisions must be made to properly
pipe the safety relief discharge
away from the boiler to the point of
discharge.
No shuto of any kind shall be placed
between the safety relief valve
and the boiler, or in the discharge
pipe between the valve and the
atmosphere. Doing so may cause an
explosion from overpressure.
The hydronic system should never be
ushed while the boiler is attached
to the system since the debris could
accumulate in the boiler and block
water from passing through the heat
exchanger.
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 (See Figure 3):
1. Isolation valves 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 pressurereducing (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. 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.
5. Include the following in the mechanical equipment in the hydronic
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.
2-6
» 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.
NOTE: The upper water connection on the back of the boiler is the outlet
connection. The lower water connection on the rear of the boiler is the inlet
connection.
NOTE: The Fulton Endura boiler does not require a primary/secondary ow
piping system. Although primary/secondary is an acceptable con guration,
the boiler does not have a minimum return water temperature requirement
and the heat exchanger will not be harmed by low ow or zero ow
conditions. See Figure 3 for a sample piping layout.
6. Install ltration to remove particulates if appropriate. A #10 mesh size is
suggested.
7. Install bypass chemical feeder for corrosion inhibitor maintenance if
appropriate.
8. Install corrosion coupon holder to assess corrosion inhibitor performance if
appropriate.
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.
9. Before installing a Endura boiler into a hydronic loop, be sure that the
system piping and any other components of the system are clean and free
of debris and any foreign matter. The hydronic system must be completely
ushed prior to installing the boiler itself.
NOTE: Although motorized isolation valves are not required in a primary
only arrangement , they can help ensure system e ectiveness. Proper
control strategy must be used to ensure ow paths in the hydronic loop and
residual heat in pressure vessel can be adequately dispersed when a boiler
is disabled.
Meet Water Chemistry Requirements
System water chemistry requirements are as follows:
pH: Range of 8.5 - 10.5
Oxygen: Less than 250 ppb (operating condition)
Total Iron/Copper: Less than 5 ppm
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.
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.
Do not store or use gasoline or other
ammable vapors and liquids or
corrosive materials in the vicinity of
this or any other appliances.
Chloride: Less than 200 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. If RO/DI water is used as a source for hydronic loop water or makeup water,
it must be neutralized to a pH of 8.5 - 10.5 prior to entering the boiler.
Failure to neutralize the RO/DI water will void the pressure vessel warranty
and may cause high general corrosion rates.
The system must have an automatic pH controller to monitor and log the
levels. This must be independent of other chemical feed systems.

FIGURE 3 SAMPLE PIPING LAYOUT
Note: Sample piping layout (P&ID) is a general representation of system installation. Good practice should be used in system design,
including but not limited to adequate pipe/valve sizing and natural ow path for system water.
Makeup water pH range must be 7.5 - 8.8; the boiler
water must be maintained within pH range of 8.5 -
10.5.
4. 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.
5. For freeze protection an inhibited propylene glycol
is recommended. Only use mixtures formulated for
hydronic systems. Do not use automotive glycol.
6. At a minimum, the hydronic uid should be checked for
glycol concentration and pH once a year.
2-8
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
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 boiler
supply.
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.
4 CAUTION
Care needs to be taken to eliminate
oxygen from the water system, as
excess oxygen in the system will
reduce the life of any boiler. The
boiler warranty does not cover heat
exchanger replacement due to oxygen
contamination of boiler water.
Heat exchanger failure due to
inappropriate water quality, foreign
matter or debris damage is not covered
under the warranty.
If the piping system attached to this
unit will be chemically cleaned, the
boiler must be disconnected from the
system and a bypass installed so that
the chemical cleaning solution does
not circulate through the boiler.
Fill the Boiler With Water
To be sure that the boiler is not air-bound, open the pressure-relief valve located
at the rear of the boiler. Leave the relief valve open until a steady ow of water is
observed. Close the valve and nish lling the system.
Install Gas Piping
The Endura boiler is factory test red and combustion is adjusted per the boiler
data plate and test re sheet.
The gas train components are con gured to operate at speci c gas pressure
requirements. The speci c requirements for each boiler are called out on the
boiler nameplate, located on the back of the boiler.
Adhere to the following for gas piping installation:
1. See Table 3 for required natural gas pipe size, based on overall length of
pipe from the meter plus equivalent length of all ttings. Approximate
sizing may be based on 1,020 BTU for 1 cubic foot of natural gas.
2. Piping must be installed such that no piping stresses are transmitted to the
boiler. The boiler cannot be used as a pipe anchor.
3. The boiler and all gas piping connections must be pressure-tested and
checked for leaks before being placed into service. Test with compressed
air or inert gas if possible.
4. The boiler must be disconnected at the boiler manual shuto valve

accordance with the National Fuel Gas Code, ANSI Z223.1-1991 or latest
addenda. In Canada gas installations must by in accordance with the current
CAN/CSA B149.1 and 2 and/or local codes.
Components Requiring Ventilation to the Outdoors
The following do not require ventilation to the outdoors, as there is a vent limiter
in use:
Gas valve on the main fuel train
Lock-up regulator on the main fuel train
Regulator on the ignition enrichment line
An authority having jurisdiction may not permit the use of a vent limiter. In this
case, please use the following general guidelines:
A parts kit must be ordered from your Fulton manufacturer’s representative
for plumbing the vent lines outside the cabinet. Improper plumbing will
cause the cabinet to lose its sealing, which can lead to improper combustion
and bypassing of the air lter. Instructions are included in the kit.

4. 1 1/2” Stainless or Galvanized Union
recommends connecting it before the “fast ll” valve
to the boiler supply but after the back ow preventer
to avoid contamination of a potable water supply.
Maximum allowable water pressure to the compression
tting is 100 PSI (689.5 kPa).
6. Connect 1 inch (25.4 mm) condensate drain(s) (at the
rear of the boiler), to the 1 inch (25.4 mm) inlet at the
base of the drain tank. The header must be at least 5.5
inches (14.2 cm) below the condensate outlet of the
individual boiler, and must remain ooded - achieved
by ensuring it is at least 5.5 inches (14.2 cm) below the
outlet of the condensate drain trap.
7. Connect the 1.5 inch (38.1 mm) drain outlet to an
appropriate waste line following applicable codes. The
1.5 inch (38.1 mm) drain connection on the drain tank
must be the highest point prior to going to the drain.
Failure to keep drain piping lower than this point will
result in over ow of the drain tank. Slope the drain
pipe away at a minimum pitch of 1 inch (25.4 mm) for
every 12 feet (3.65 m).
8. (U.S. Only) Attach a ¼” water supply to the
compression tting on the oat. The water line must
be connected to an uninterruptible supply. Fulton

Install pH Neutralization Kit
The pH Neutralization Kit is a Fulton-provided kit designed to
bring the pH level of the boiler’s condensate to a neutral level.
It is not a replacement or alternative for the Condensate Drain
Trap. See Figure 5.
Adhere to the following for pH Kit installation:
1. Use stainless or galvanized pipe and ttings to connect
condensate drain to kit.
2. Connect kit downstream of Condensate Drain Trap. See
Figure 6.
NOTE: Replacement bags are available from your Fulton local
representative. The medium in the container will neutralize the condensate
of 12 MM Btu’s for approximately 6 months.
Venting
Adhere to the following venting requirements:
1. The Endura boiler can operate to the combined intake and ue pressure
drops without altering standard capacities: See Table 4.
2. The pressure drop readings at the boiler exhaust connection and air intake
connection cannot exceed the maximum value stated in Table 4. This
means that the combined pressure drop through the air intake venting (if
installed) and exhaust venting cannot exceed the maximum value stated
in Table 4; this is typically approximately 35 feet (10.6 m) with 4 elbows of
connection size piping. Alternative distances and number of elbows may
be appropriate if determined by the venting designer to be within the
pressure drop ranges in Table 4. If pressure drop is exceeded, the boiler
may have to be de-rated or operational issues will result. Also, the pressure
at the boiler exhaust connection must not exceed a maximum negative
value as stated in the table. This pressure must remain relatively constant
throughout the operation of the boiler. Drastic draft changes during
operation may result in generation of excessive carbon monoxide or soot.
To decrease termination noise, increase the venting size at the termination
points. This will slow the air velocity causing a reduction in noise. Do not
terminate the venting in an enclosed area. Care must be taken when
selecting the orientation of the terminations.
! 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.
NOTE: Consult your venting pipe supplier for assistance with sizing of vent
materials and other potentially required accessories.
3. Do not use boot tees or bullhead tees.
4. Barometric dampers should never be used in a condensing boiler
application even if the draft is negative, this is because barometric
dampers physically open to the mechanical room and it will be possible for
ue gas condensate to drain down the outside of the stack.
5. The air intake system must be designed to prevent any moisture from
draining to the boiler.
6. The layout of the piping used for air intake and exhaust must be done in a
way that facilitates smooth travel and natural ow. Performing a pressure
drop calculation isn’t enough information to make sure a draft system will
perform adequately. Good practice must be used by the designer and
installer. Some recommendations:
degree elbows, short radius elbows especially right at the
connections to the boilers
Avoid extensive direction changes ( ue gases being required

Combustion Air Supply From the Boiler Room
Adhere to the following for installation:
1. Adequate combustion air and ventilation must be
supplied to the boiler room in accordance with local
codes and NFPA54/ANSI Z233.1, Section 5.3, Air for
combustion and ventilation. Ensure space and nearby
products are evaluated for the potential of combustion
air contaminants. See Table 6.
TABLE 6 PRODUCTS/CONTAMINANTS TO AVOID
Products to avoidProducts containing chloro/fl ouro-
2. The boiler room must meet the NFPA criteria for a noncon ned space.
Dry cleaning/laundry areas; swimming pools; repair shops; processing plants; manufacturing plants,
new construction
9. For multiple boiler installations, multiply the number of
boilers by required free area per boiler.
10. The installation of exhaust fans in a boiler room is not
recommended.
11. 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 in the
combustion system can create hazardous conditions.
If foreign substances can enter the air stream, the
boiler combustion air inlet must be piped to an outside
location.
12. Particulate matter or chemicals (example:
perchlorethylene, halogenated compounds) in the
combustion air supply to the boiler will cause damage
or failure to the burner. High-risk situations for
particulate matter to be in the air include construction
and maintenance activities. See Table 6.
3. It is important to provide free access of air to the boiler.
Per ASME Section VI Para. 6.04 and NBIC, unobstructed
air ventilation openings (one near ceiling, one near
oor) should be sized on the basis of one square inch
free area per 2000 BTU/HR maximum fuel input of the
combined burners located in the boiler room. This is
subject to state and local regulations.
4. Consistent proper ventilation of the boiler room is
essential for good combustion. Install two fresh air
openings, one at a low level, 24” (610 mm).
5. Boiler room pressure must be neutral relative to the
outdoors.
6. Ensure there is not negative pressure in the boiler room.
If any negative pressure is present, sealed combustion
to the outdoors must be ensured.
Air Piped From Outside Boiler Room
Adhere to the following for installation:
1. The combustion air supply can be piped directly to the
2. The air intake must be piped out of the building if the boiler room contains
contaminated air.
3. Air Intake pipes and ttings shall be Schedule 40 PVC pipe or galvanized
steel. All Schedule 40 PVC pipe, ttings, primer and cement must conform
to American National Standard Institute and the American Society for
Testing and Materials (ANSI/ASTM standards) per pipe manufacturer’s
requirements.
4. Intake PVC piping must be assembled using cement. This will ensure that
the intake is air tight and will not allow contaminates from the boiler room
into the boiler. The cement must be free owing and contain no lumps,
undissolved particles or any foreign matter that adversely a ects the joint
strength or chemical resistance of the cement. The cement must not show
gelation, strati cation, or separation that cannot be removed by stirring.
5. Adhere to procedure for cementing joints (per ASTM D2855).
Air Filter
The air lter requires monthly maintenance. See Maintenance section of this
manual.
! WARNING
Cements for plastic pipe are
ammable liquids and 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. Avoid contact of cement with
skin and eyes.
Never install a barometric damper on
ue systems designed with positive
pressure.
Assure all electrical connections are
powered down prior to attempting
replacement or service of electrical
components or connections of the
boiler.
Do not use the boiler/burner as
support for ducted air piping.
Ducted piping must be supported
independently of the boiler.
Exhaust Venting
The Endura is equipped with a vent connection at the lower rear of the boiler.
Adhere to the following for installation:
1. The Endura is a Category II/IV appliance, thus venting material must be
appropriate for condensing, positive pressure applications. Any venting
material supplied for the Endura boiler must be AL29-4C or 316L SS, listed
and labeled to UL1738, and guaranteed appropriate for the application by
the manufacturer and supplier of the venting. It is also acceptable to vent
the Endura Cat. II (negative pressure, condensing).
2. The exhaust line must be sloped down toward the drain with a pitch of
at least 1/4” per foot (6.35 mm per .3 m). Failure to do so can result in a
condensate pocket, which can result in an inoperative boiler. There must
be no low spots in the exhaust pipe, as this can also result in a condensate
pocket. A high spot is acceptable, provided the pitch from the high spot
is maintained back to the boiler or to the outside point of the exhaust.
Always avoid rigid connections between piping and structural members of
the building.
3. Follow vent manufacturer’s instructions for installation of exhaust venting.
Refer to table for acceptable venting materials. Use of cellular core PVC
(ASTM F891), cellular core CPVC , or Radel® (polyphenolsulfone) in venting
systems is prohibited.
Particulate matter or chemicals in
the combustion air supply to the
boiler will cause damage or failure to
the burner and is not covered under
warran ty.
Regular maintenance of the
lter is required (as per the lter
manufacturer’s recommendations) to
maintain the Endura warranty.
Negative pressure in the boiler room
can cause operational issues and
boiler damage.

! WARNING
Do not terminate venting into an
enclosed area.
Never use open ame or smoke from
a cigarette, cigar, or pipe as a testing
method during boiler installation,
operation, or maintenance.
Foreign substances, such as
combustible volatiles in the
combustion system can create
hazardous conditions. If foreign
substances can enter the air stream,
the boiler combustion air inlet must
be piped to an outside location.

*PVC, CPVC and polypropylene are approved for EDR-1000 only.
5. The condensate connection on the boiler should be piped into the stack
drain piping. The pipe from the boiler directed to the drain should be
installed at a slope of ¼” per foot (6.35 mm per .3 m).
6. Ensure that the condensate drain piping will not be exposed to
temperatures where water/condensate will freeze in the lines.
Common Venting Layouts for Endura
It is possible to combine the air intake and/or exhaust piping for a number of
Endura boilers. The pressure drop across the common system (combined total
for air intake and exhaust) cannot exceed the pressure drop requirements for an
individual boiler. See Table 4.
Adhere to the following for installation:
1. Consult your venting supplier for guidance in designing common vented
installations. It is imperative to design such systems to prevent back ow of
exhaust gases through idle boilers.
2. Endura boilers cannot be common vented with other equipment.
When designing a draft system for a quantity of two or more Endura boilers, the
following items must be considered and addressed by the parties responsible for
designing and providing that system:
MULTIPLE BOILERS SHARING AN EXHAUST STACK, NEGATIVE PRESSURE IN THE
COMMON HEADER:
1. Precautions must be taken to ensure that the negative pressure in the
common header stays within the stated ranges (refer to table 4) at all
possible conditions. This includes considering all possible operating
conditions of the stack, including:
All boilers on at their maximum input rating capacity
One boiler in the system on at a low re position
No boilers on, light o condition
2. Draft accessories, such as stainless steel dampers, may be required
depending on the variety of conditions experienced in the draft system.
2-18
MULTIPLE BOILERS SHARING AN EXHAUST STACK, POSITIVE PRESSURE IN THE
COMMON HEADER:
1. Precautions must be taken to ensure the prevention of ue gases from
traveling back through idle boilers ( ue gas recirculation, FGR). Looking
at the condition of all boilers on at high re condition will facilitate the
selection of the diameter of the stack that is appropriate; however there is
still a risk of FGR that needs to be managed. Options to consider for this
management include the following:
Mechanical draft assist systems (exhaust fans).
Stainless steel dampers installed in the individual stack sections prior to
the common header connection. Damper must be controlled so that
it will close when a boiler is disabled or idle.
Other solutions can be considered as long as the precautions to prevent
FGR have been thoroughly evaluated.
NOTE: Consider all possible draft conditions (based on the modulation
and quantity of the boilers). When doing pressure drop calculations for a
system of boilers sharing air intake or exhaust piping, it is important for
the designer and provider of the draft system to consider the full scope of
possibilities that can be experienced by that system. This includes looking
at the condition of one boiler on at a low re condition and all units on at a
high re condition.
! WARNING
The exhaust vent installer should be
familiar with Federal Codes as well
as local codes and regulations.
4 CAUTION
To prevent the possible re-circulation
of ue gases, the vent designer must
take into consideration such things
as prevailing winds, eddy zones,
building con gurations, etc. It is the
responsibility of the installer to locate
the exhaust duct in such a way that it
does not become blocked due to snow,
ice, and other natural or man-made
obstructions.
Do not locate the vent termination too
close to shrubbery as ue products may
stunt their growth or kill them.
Venting Terminations
Adhere to the following for installation:
1. All vent pipes and ttings must be installed with appropriate air space
clearances to combustibles. These air space clearances apply to indoor or
outdoor vents—whether they are open, enclosed, horizontal or vertical
or pass through oors, walls, roofs, or framed spaces (See Figures 8 and
9). The air space clearances should be observed to joists, studs, sub oors,
plywood, drywall or plaster enclosures, insulating sheathing, rafters,
roo ng, and any other material classed as combustible.
2. The required minimum air space clearances also apply to electrical wires
and any kind of building insulation.
3. Adequate provision must be made to support the weight of the exhaust
venting. It cannot be supported by the boiler exhaust connection.
4. Listed termination parts must be used.
5. Select the air intake point of penetration where a minimum of 1/4” per foot
(6.35 mm per .3 m) upward pitch can be maintained.
6. When penetrating a non-combustible wall, the hole through the wall must
be large enough to maintain the pitch of the vent and provide sealing. Use
adhesive material to seal around the vent on both sides of the wall. When
penetrating a combustible wall, a wall thimble must be used. See Figure 7
for installation instructions. Minimum wall thickness through which vent
system may be installed is 3.25 inches (8.26 cm). Maximum wall thickness
through which vent system may be installed is 20 inches (50.8 cm).
It is the responsibility of the installer
to ensure ue gas is not recirculated
to the air inlet venting, as improper
combustion will result.

professional codes and regulations.
Wall Thimble Installation
Adhere to the following for installation (see Figure 7):
1. The thimble is inserted through the wall from the outside.
2. Secure the outside ange to the wall with nails or screws, and seal with
adhesive material.
3. Install the inside ange to the inside wall, secure with nails or screws, and
seal with adhesive material.
4. Pass the vent pipe through the thimble from the outside and join to the
rest of the vent system. Seal the pipe to the thimble ange with adhesive
material.
5. Install two pipe retaining clamps around the intake as well as vent pipes on
both ends of the wall thimble (on the inside and outside of the wall)
through which intake and vent pipes are passed. They will prevent the
intake and vent pipes from being pushed or pulled.
NOTE: The vent termination is joined to the vent pipe outside the wall. Use
the same joining procedures for vent pipe and ttings.
1. The termination of the vent system must be at least 12 inches (30.48 cm)
above the nished grade, or at least 12 inches (30.48 cm) above normal
snow accumulation level (for applicable geographical areas).
2. The termination of the vent system shall not be located in tra c areas
such as walk ways, adjacent buildings, operable windows and building
openings unless the venting system is at least 7 ft (2.1 m) above nished
grade, (National Fuel Gas Code, ANSI Z223.1).
3. The vent terminations must be at least 4 ft (1.22 m) horizontally from
electric meters, gas meters, regulators, and relief equipment.
4. When installing inlet and exhaust terminations on the same wall, the
exhaust outlet must be installed horizontally 4 ft (1.22 m) minimum above
and downwind from air supply inlet to prevent exhaust recirculation.
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.
5. Under certain wind conditions, some building materials may be a ected
by ue products expelled in close proximity to unprotected surfaces.
Sealing or shielding of the exposed surfaces with a corrosion resistant
material (such as an aluminum sheet) may be required to prevent staining
or deterioration. Flue should be directed away from surfaces, if possible.
6. The minimum vent height should extend at least 3 feet (0.9 m) above the
roof, or at least 2 feet (0.6 m) above the highest part of any structure within
10 feet of the vent.
7. If the exhaust vent terminates within 10 ft (3 m) horizontally of the air inlet,
the exhaust vent must be at least 4 ft (1.2 m) above the inlet. Dimensions
provided are minimum, and may or may not be su cient for conditions at
a speci c job site.
8. To prevent the possible re-circulation of ue gases, the vent designer
must take into consideration such things as prevailing winds, eddy zones,
building con gurations, etc. Fulton cannot be held responsible for the
e ects such adverse conditions may have on the operation of the boilers.
9. It is important to locate the exhaust duct in such a way that it does
not become blocked due to snow, ice, and other natural or man-made
obstructions. If terminating into a prevailing wind, direct elbow upward.
Avoid areas (example: courtyards) where swirling high winds may be
present.
Removing an Existing Boiler
When an existing boiler is removed from a common venting system, the
common venting system is likely to be too large for proper venting of the
appliances remaining connected to it.

! 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.
At the time of removal of an existing boiler, while the other appliances remaining
connected to the common venting system are not in operation, the following
steps should be followed with each appliance remaining connected to the
common venting system placed in operation:
1. Seal any unused openings in the common venting system.
2. Visually inspect the venting system for proper size and horizontal pitch and
determine that there is no blockage or restriction, leakage, corrosion or
other de ciency, which could cause an unsafe condition.
3. Insofar as is practical, close all building doors and windows and all doors
between the space in which the appliances remaining connected to the
common venting system are located and other spaces of the building.
Turn on clothes dryers and any appliances not connected to the common
venting system. Turn on any exhaust fans, such as range hoods and
bathroom exhausts, so they will operate at maximum speed. Do not
operate a summer exhaust fan. Close replace dampers.
4. Place the appliance being inspected in operation. Follow the lighting
instructions. Adjust the thermostat so that the appliance will operate
continuously.
5. Test for spillage at the draft hood relief opening after 5 minutes of main
burner operation. Do not use the ame of a match or candle or smoke
from a cigarette, cigar or pipe.
6. After it has been determined that each appliance remaining connected
to the common venting system properly vents when tested as outlined
above, return doors, windows, exhaust fans, replace dampers and any
other gas-burning appliance to their previous conditions of use.
7. Any improper operation of the common venting system should be
corrected so the installation conforms with the National Fuel Gas Code,
ANSI Z223.1. When resizing any portion of the common venting system,
the common vent system should be resized to approach the minimum size
as determined using the appropriate tables.
Electrical Connections
Motors are designed to operate within the following limits at the motor
terminals:
AC power supplied is within +/- 10% of the motor rated voltage with the
rated frequency applied; or AC power supplied is within +/- 5% of the rated
frequency and with the rated voltage; or a combined variation in voltage
and frequency of +/-10% (sum of absolute values) of rated values provided
the frequency variation does not exceed +/-5% of rated frequency.
The Endura units are to be powered with 120 VAC, single phase, 60 Hz power. The
circuit should have a circuit breaker rated for 20A and the units will draw 15A (8A
for EDR-1000) on a regular basis, with the fan at maximum speed.

Fill and Purge the System
Completely ll and purge the heating system as follows:
1. Close combination shuto /purge valve in supply, all drain cocks, the
shuto valve for the pressure reducing ( ll) valve, and all manual air vents.
2. Open a system valve, or ll through a drain connection.
3. Water will now begin to ll the system. Open the safety relief valve.
Continue lling until a constant stream of water (no bubbling) is
discharged from the safety relief valve.
4. At this point, the system has been initially lled. However, air pockets may
still remain at high points in the system and in heating loops above the
level of the safety relief valve valve. It is quite possible, depending on the
particular system that all piping above the safety relief valve still contains
air. If manual vents are installed on the system high points, these should
be opened to vent these locations. When only water is discharged from all
vents, the initial purging is complete.
3-2
5. With the gas shuto valve closed, turn on power to the boiler and operate
the circulator. Circulate the system water for approximately 30 minutes to
move all air to the automatic air separation point.
6. Check temperature/pressure indicator reading, which should equal the
pressure-reducing ( ll) valve set pressure. No more water should be
entering the system. Close the shuto valve on the cold-water ll line.
7. Visually inspect all pipe joints and equipment connections for leaks. If
necessary, drain system, repair leaks and re ll/purge the system. If no
pressure drop is detected for a period of two hours under pressure, the
system may be considered watertight.
8. When purging is completed, make sure the following are open—
combination shut-o /purge valve, shuto valve to pressure reducing ( ll

Commission The Boiler
! WARNING
Do not attempt to start the boiler for
any testing before lling and purging
the boiler. A dry re will seriously
damage the boiler and may result in
property damage or personnel injury
and is not covered by warranty.
Before commissioning the boiler,
verify with authorized personnel that
the gas lines have been purged.
Never attempt to operate a boiler
that has failed to pass all the safety
checks.
Never leave an opened manual air
vent unattended. In the event an
opened vent is left unattended, water
damage could occur.
Adhere to the following when commissioning the boiler:
1. Verify with authorized personnel that the gas lines have been purged. Do
not proceed without veri cation.
2. Familiarize all personnel on all aspects of boiler use, safety, and contents
of this manual. This includes, but is not limited to, the use of the controls,
lighting, and shutdown procedures.
3. Review the unit-speci c burner and control schematics, and follow
appropriate instructions.
System Design and Boiler Operation
The Endura boiler must be installed in an appropriately designed system per
Installation section of this manual. The boiler shall be operated/controlled
to ensure the boiler does not cycle more than 12,000 times per year and the
temperature di erential across the boiler does not exceed 100°F (38°C).
Commission The Boiler: Dungs Zero Governing Gas
Valve
4 CAUTION
Do not use this equipment if any part
has been under water (or subjected to
heavy rains/water if the equipment
does not have NEMA 4 wiring, controls
and instrumentation). Immediately
call a quali ed service technician to
inspect the equipment and to replace
any part of the control system and/or
gas control(s) which have been under
water.
NOTE: In areas where NOx emission regulations apply, the O2 level should
be set so that the NOx level does not exceed local code at any point during
operation. As a general guide, the combustion will be approximately 5.1 %
O2 across the ring range. In areas where NOx emission regulations do not
apply, the 02 level can be set as low as 3% 02 at high re and 5% 02 at low
re. Low re combustion should always be set after high re.

4 CAUTION
Commissioning/Start up by a nonFulton authorized person will void the
product warranty.
Please read these instructions and
post in an appropriate place near the
equipment. Maintain in good legible
condition.
When commissioning is complete, Sola
control must be placed into automatic
mode.
NOTE: Perform the following steps for eld commissioning with the Dungs
Gas Valve (Figure 10).
NOTE: A combustion analyzer will be required when making changes to
the Dungs valve settings.
1. Follow the steps in the SOLA Hydronic Controller section of this manual
to access the parameters to run the boiler in manual mode.
2. Turn the boiler on and make sure that there is a call for heat. If the unit
does not go directly to pre-purge, there is not a call for heat or there is an
interlock open. If all interlocks are closed, the unit will drive to the max
RPM for pre-purge and begin countdown.
3. When pre-purge is nished, the unit will go to the light-o point.
4. From the test re sheet verify what was used for a low re RPM setting.
Input this setting into the Sola manual ring rate (Figure 14). Once the
boiler is at this RPM check combustion. Unless the combustion is way out
of the range from the test re sheet proceed slowly to the high re RPM
point. Once at high re take a combustion reading.
NOTE: Gas Valve adjustments will change combustion. Only minor
changes should be required due to the boiler being fully test red at the
factory. Gas valve adjustments should only be made at high re and low
re. If an adjustment is made at low re it will e ect high re, and vice
versa. Always adjust high re before low re.
5. To increase the O2 level at high re, turn the Valve Adjustment (Gas valve
shutter on the downstream side of the gas valve, see Figure 10) slotted
screw counter-clockwise. To decrease O2 level, turn the Valve Adjustment
screw clockwise. Once the correct O2 level is reached slowly go back to
low re and check combustion.
6. When you have reached low re RPM and if O2 adjustments are required
the Valve O set Adjustment (allen screw on the side of the valve, see
Figure 10) will need to be rotated. To increase O2 turn the Valve O set
Adjustment screw counter-clockwise, turn in the opposite direction to
decrease O2.
7. Making changes to either adjustment on the valve will change the
combustion through the range. When any adjustments are made the
combustion should again be checked at high and low re.
8. Verify combustion settings are in the range speci ed by Table 9.
NOTE: Proper set up of the Ignition Enrichment gas is crucial to the
“light-o ” of the boiler and requires veri cation in the eld during initial
commissioning. Fulton recommends the Ignition Enrichment setting is
veri ed during the yearly preventative maintenance.
9. Once nal eld combustion is completed at low and high re, the ignition
enrichment setting requires veri cation. Use the factory test re sheet to
determine the factory test re light-o rpm’s. Input this setting into the
10. Connect an inches of water column measuring device (i.e., manometer) to
the Enrichment gas valve test port (Figure 10). Insert combustion analyzer
probe into the ue gas outlet port.
11. Open the front access door and locate the Enrichment test button located
at the top of the electrical box. Turning the Enrichment test button on
activates a “1-shot relay” allowing 30 seconds to measure the Enrichment
gas valve outlet pressure and stable O2%. Use the factory test re sheet
to reference the Enrichment gas valve outlet pressure and O2%. (site
conditions will ultimately determine speci c settings).
