Alternate gas pressure arrangements may apply based on conguration and/
or local code requirements. Please verify gas pressure ratings for your boiler by
viewing the boiler name plate and consulting with the authority having jurisdiction.
Typical 120 VAC controls allow for a +10% and a -15% voltage uctuation.
Voltages lower than 120 V can result in slightly decreased available output.
*Standard congurations may be available as an option; please consult factory.
Note: All dimensions are approximate and are subject to change without notice.
Adhere to the following for clearances and serviceability:
1. All local and national codes (NFPA, ANSI, UL, CSA,
ASME) must be followed for proper clearances and
serviceability for your boiler or heater. Authorities
having jurisdiction should be consulted before
installations are made.
2. Appropriate front, back, side and top clearances must
be maintained (Figure 1). This will allow access around
the equipment to facilitate maintenance and a safe
work environment. A 1-inch (25.4 mm) side clearance
is acceptable between any number of boilers. Custom
congurations may not allow 1-inch (25.4 mm) side
clearance. Although a 1 inch (25.4 mm) side clearance
is permitted, allowing 24 inches (610 mm) will
facilitate and expedite maintenance and any advanced
troubleshooting.
NOTE:Side panels are latched; however, maintenance and
service does not require boiler access through side panels. All
maintenance and service can be performed from front, rear,
and top of boiler.
3. Ensure all labels on the boiler will be fully visible for
maintenance and inspection.
4. Do not place any boiler room accessories, or other
components, on the Endura skid.
2. The discharge pipe must:
» Not have a diameter less than the full area of
the valve outlet.
» Be as short and straight as possible and so
arranged as to avoid undue stress on the valve.
» Be supported by means other than the safety
valve itself.
» Be piped to avoid danger of scalding
personnel.
NOTE:Each boiler is equipped with a pressure-temperature
gauge to be installed in the outlet piping section of the boiler.
Gauge must not be isolated from the boiler by any valve.

! 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.
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, you must analyze and treat each installation uniquely.
Adhere to the following for water piping installation (see Figures 4 7):
Manual isolation valves are recommended on both water connections for
ease of service.
Install piping so that the boiler is not supporting any piping load.
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.
To prevent scale and 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 maintaining system pressure.
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.
Provide at least 6 inches (152 mm) clearance from hot water pipes to
combustibles.
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.
When used 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.
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 should be designed to
add water to the system at the outlet of the boiler but 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 specications.
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.
2-6
Install ltration in the common loop or per boiler to remove particulates if
Install bypass chemical feeder for corrosion inhibitor maintenance if
appropriate.
Install corrosion coupon holder to assess corrosion inhibitor performance if
appropriate.
Before installing an 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.
FIGURE 3 TYPICAL WATER SIDE PRESSURE DROP
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.
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.
Variable Primary Piping Arrangement
Endura boilers are designed for installation in variable primary ow piping
arrangements (see Figures 4 and 5), sometimes referred to as full ow systems.
This arrangement eliminates temperature mixing associated with primarysecondary piping, thereby delivering the lowest temperature water directly
to the boiler return connections and increasing thermal eciency of the
condensing boiler plant.
NOTE:Although it is acceptable to install Endura boilers in a primary-secondary
conguration, it is not required.
Adhere to the following for variable primary piping arrangements:
Select pump(s) with sucient total dynamic head for the pressure drop of the
loop at design ow. See Figure 3 for the water side pressure drop through
the boiler. The Endura boiler does not have a minimum ow requirement.
It will automatically perform a safe shutdown in the event of a low ow or
zero ow condition; however, proper design ow will be required to deliver
heat to users and prevent nuisance high temperature limit trips.
Use motorized isolation valves: Ensure system eectiveness by eliminating
ow through idle boilers accordance with ASHRAE 90.1-2013 (6.5.4.3.2).
Blending of unheated supply water may impact temperature control
operation or cause manual reset high temperature lockouts. One

Do not use matches, candles, ame or
other sources of ignition to check for
gas leaks.
motorized isolation valve should be installed per boiler; two-position type
actuator, open or closed. It is acceptable to install the valve on either the
inlet or the outlet piping of each boiler.
Motorized isolation valve control: Ensure ow paths in the hydronic loop
and residual heat in the pressure vessel is adequately dispersed when the
burner is disabled. The valve control system must be capable of leaving the
lead boiler valve open at all times.
Use a reverse return header to properly balance ow across the boilers
for multiple boiler systems: Where reverse return cannot be used, it is
recommended to install a balancing valve per boiler.
Do not install three-way mixing valves or minimim temperature protection:
The Endura boiler does not have a minimum return water temperature
requirement.
Primary-Secondary Piping Arrangement
It is acceptable to install the Endura boiler in a primary-secondary arrangement,
although this arrangement is not required. See Figures 6 and 7. Primarysecondary arrangements are used to decouple the water ow of the primary
(boiler) loop from the secondary (system) loop. Temperature mixing occurs in the
shared piping region.
Adhere to the following for primary-secondary piping arrangements:
Typical shared piping methods include closely spaced tees, a buer tank, or
a hydraulic separator.
When using closely spaced tees as a decoupling method, the tees should be
separated by four pipe diameters or less.
Install the dedicated boiler circulator on the inlet side of the Endura boiler,
pumping into the return connection. Select pump(s) with sucient total
dynamic head for the pressure drop of the loop at design ow. See Figure 3
for the water side pressure drop through the boiler.
For multiple boiler systems:
» Use a single common supply and a single common return connection
into the secondary (system) piping. Do not use separate connections
for each boiler into the secondary piping.
» Use a reverse return primary header to properly balance ow across the
boilers. Where reverse return cannot be used, it is recommended to
install a balancing valve per boiler.
Meet Water Chemistry Requirements
2-10
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.
Chloride: Less than 200 ppm Hardness: Less than 3.5 grains per gallon (60 ppm) in make-up/ll water.
Calcium buildup on heating surfaces is not covered under warranty.
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.
! 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.
If the water supply must be
temporarily disconnected from the
condensate drain trap, the boilers
must be turned o to prevent
accidental ue gas emission into the
boiler room.
4 CAUTION
Some soap used for leak testing is
corrosive to certain types of metals.
Clean all piping thoroughly after
completing the leak check.
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 eciency and
useful life of the boiler and is not covered under warranty.
5. For freeze protection, an inhibited propylene glycol is recommended.
The maximum concentration is 50% glycol by volume. Only use mixtures
formulated for hydronic systems. DOWFROSTTM HD is recommended. Do
not use automotive glycol.
6. At a minimum, the hydronic uid should be checked for glycol
concentration and pH once a year, or per glycol manufacturer schedule. A
refractometer is recommended.
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.
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. If
cleaning is desired, ush the boiler with
clean domestic water only.

INSTALLATIONEDR-IOM-2019-0212SECTION 2
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 on the suction side of the system circulator(s).
4. If an air cushion type expansion tank is used, pipe tank
directly into boiler supply on the suction side of the
system circulator(s).
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.
Gas Supply Piping
The Endura is a gas red fully modulating boiler that requires
gas delivery at a relatively constant pressure and caloric
content. This ensures ecient and reliable combustion. A
lock-up style regulator is factory-mounted in the gas train. Do
not modify the gas train.
The packaged gas train (See Figure 8) is congured to operate
at specic gas pressure requirements. The requirements are
detailed on the boiler name plate, located on the back of the
boiler.
The Endura boiler is factory test red and combustion is
adjusted per the boiler data plate and test re sheet.

Static inlet gas pressure: Measure while boiler is idle.
Verify pressure is within allowable range.
Dynamic inlet gas pressure: Measure while boiler is in
operation at maximum ring rate. Verify pressure is
within allowable range.
The gas delivery system must provide a stable and
consistent pressure across the entire turndown range,
including light o and idle conditions.
Maximum inlet gas pressure drop from static to
dynamic must not exceed 15%, or the maximum
allowable by local code (CSA B149 clause 6.3.2 for
Canada). The stricter of the two shall apply.
Gas Pressure Requirements
The minimum gas pressure required is 4” W.C. For gas pressures
exceeding 28”W.C. (14”W.C. Canada), a step down regulator
(not supplied) must be installed in the gas supply piping.
If the level of pipe system cleanliness is unacceptable
or unknown, it is recommended that a gas lter be
installed prior to the regulator.
On the outlet of the regulator: Install a straight and
uninterrupted section of pipe matching regulator
connection size with a minimum length of 10 pipe
diameters prior to any valves or ttings.
When installed in close proximity to an appliance, some
regulators may experience oscillation (hunting) or an
outlet pressure spike when demand ends. Provide
adequate volume by locating the regulator a minimum
of 10 total linear feet of pipe from boiler fuel train inlet.
Consult the regulator manufacturer for installation
requirements.
The body size should never be larger than the pipe size.
However, a properly sized regulator may be smaller
than the pipeline.
The inlet pressure used for sizing should be measured
directly at the regulator inlet. Measurements taken at
any other point may be subject to losses associated
with upstream piping.
Line Gas Pressure Regulation
When inlet gas pressure exceeds 28”W.C. (14”W.C. Canada),
a line gas pressure regulator is required to step the gas
pressure down below maximum pressure.
Proper selection and installation of a gas pressure regulator
is essential in providing ideal conditions for ecient and
reliable combustion. Adhere to the following guidelines
when selecting and installing a gas pressure regulator:
A sediment trap is recommended prior to the inlet of

Gas Piping Installation
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. See Figures
6 and 7 for piping arrangements.
2. Install a manual gas shuto valve and union prior to the
boiler.
3. Piping must be installed such that no piping stresses
are transmitted to the boiler. The boiler cannot be used
as a pipe anchor.
4. 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.
5. The boiler must be disconnected at the boiler manual
shuto valve (located at the end of the supplied gas
train) from the gas supply piping system during any
pressure testing of the system at pressures in excess of
2.0 psig (55 inch W.C.).
6. Gas Piping must be installed in accordance with
National Fuel Gas Code, ANSI Z223.1 1991 or latest
addenda and any other local codes, which may apply.
7. The pipe and the ttings used must be new and free of
dirt or other deposits.
8. Piping must be of the proper size to ensure adequate
gas supply. A drip leg and union connection must be
installed upstream of the gas safety shut o valves and
must be a 5 inch (127 mm) minimum length.
9. Connect gas supply line to the open end of the tee on
which the drip leg is installed.

Components Requiring Ventilation to the
Outdoors
The following do not require ventilation to the outdoors, as
there is a vent limiter in use:
Lock-up regulator on the main fuel train
Regulator on the ignition enrichment line
An authority having jurisdiction (AHJ) may not permit the
use of a vent limiter on some or all components. If venting is
required, use the following general guidelines:
Drill an appropriately sized penetration for each vent
line through the topmost panel on the rear of the boiler
cabinet (Figure 12). Do not install any vent lines through
removable latching panels. Properly seal around the
pipe with silicone to maintain a sealed cabinet and
ensure combustion air will not bypass the lter.
Each component must have a separate vent line to
the outdoors. Vent lines must not be manifolded or
combined with any other vent or exhaust systems.
Start with the vent connection size and as soon as it is
practical, increase the pipe size one diameter. For every
ten feet of vent, increase the pipe size one diameter.
Never reduce the vent size.
Protect the vent termination from debris, dust and
insects. Install the vent termination above the snow
line and point down to prevent ingress of water. The
termination must be a minium of 3 ft (0.9 m) from a
source of ignition.
Single Boiler Drain Trap
The single boiler condensate drain trap is Fulton Part Number
4-57-005500. The drain trap must be congured one per
boiler, with a maximum of 4.0 mm BTU total. (See Figures 13
and 15).
Adhere to the following for installation:
1. The 1 inch (25.4 mm) condensate drain will be reduced
and connected to the 3/4 inch (19.05 mm) inlet on the
base of the drain trap.
2. A condensate collecting tank and condensate pump
will be required if a oor drain is not available to collect
condensate (collecting tank and pump are not supplied
with the boiler).
3. All piping (Figure 13) must be CPVC, galvanized, or
stainless steel, and be free of leaks. Copper, carbon
steel/iron pipe, or PVC are not acceptable.
4. The drain trap must be installed below the boiler
condensate drain outlet.
5. Connect the 3/4 inch (19.05 mm) trap outlet to an
appropriate waste line following applicable codes. The
3/4 inch (19.05 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 overow 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).
NOTE:Ensure piping will not be exposed to freezing
temperatures.
Install Condensate Drain Trap
A condensate drain trap is intended for use with the Fulton
Endura boiler.

Multiple Boilers Sharing A Common Drain Trap
The multiple boiler condensate drain trap is Fulton Part Number 4-57-000440. The maximum number of units to attach per
condensate drain trap is 12mm BTU total. (See Figures 14 and
1. The Fulton Endura boiler 1 inch (25.4 mm) condensate
drain will be connected to the 1 inch (25.4 mm) inlet
on the drain trap. One or more drain lines may be
connected to this inlet (max of 12 MM BTU per drain).
2. If the water supply must be temporarily disconnected,
the boilers must be turned o to prevent accidental ue
gas emission into the boiler room.
3. The condensate drain cover must be kept on at all
times, except during maintenance of the drain. This
drain should be checked regularly in your boiler
maintenance schedule.
4. A condensate collecting tank and condensate pump
will be required if a oor drain is not available to collect
condensate (collecting tank and pump are not supplied
with the boiler.)
5. All piping (Figure 14) must be CPVC, galvanized, or
stainless steel, and be free of leaks. Copper, carbon
steel/iron pipe or PVC are not acceptable.
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 overow 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. Attach a ¼” water supply to the compression tting
on the oat. The water line must be connected to
an uninterruptible supply. Fulton 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).
NOTE: Ensure piping will not be exposed to freezing
temperatures.
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 more
neutral level. It is not a replacement or alternative for the
Condensate Drain Trap. See Figures 17 and 18.

Venting Requirements
Adhere to the following venting requirements:
1. The Endura boiler can operate to the combined intake and ue exhaust
pressure drops without altering standard capacities: See Table 4.
! 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.
4 CAUTION
An uninterruptible water supply is required
for the multiple boiler condensate trap
and shall be connected to the ¼” (U.S.
only) compression tting. The water supply
maintains a water level in the drain kit to
prevent accidental ue gas emission into the
boiler room.
2. The venting system draft pressure readings at the boiler exhaust
connection and air intake connection cannot exceed the maximum
values stated in Table 4; and must remain relatively stable throughout all
operating conditions, including the ignition sequence.
NOTE:Venting pressure is the combined result of frictional pressure drop and
natural draft (stack eect) in the combustion air intake piping (if used) and ue
gas exhaust system.
3. Drastic draft changes during operation may result in the generation of
excessive carbon monoxide or soot, which may aect operational reliability
and condition of burner, ignition assembly, or other combustion system
components leading to increased maintenance or replacement of these
items.
4. The equivalent length method is not an approved engineering method
for determining acceptability of a vent system due to varying burner
modulation rates, ambient air temperatures, and ue gas temperatures,
among other factors. Combustion air intake piping (if used) must be
accounted for in an analysis of the venting system.
5. If the maximum positive pressure is exceeded, the boiler may have to be
de-rated or require the installation of draft accessories such as a properly
selected exhaust assist fan to prevent operational issues from occurring. If
the maximum negative pressure is exceeded due to excessive natural draft
(stack eect), the exhaust system may require the use of draft accessories
such as a xed-position balancing bae or modulating overdraft damper.
Draft accessories must be appropriate for Category II/IV installations
and are not included with the boiler. Consult your venting supplier for
recommendations.
6. Adhere to local and jurisdictional codes and regulations, which may dier
from recommendations and diagrams contained in this manual.

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.
7. Site specic conditions not addressed in this manual may require
additional precautions or design considerations. Consult your local Fulton
Representative and venting supplier for recommendations.
NOTE:Consult your venting pipe supplier for assistance with sizing of vent
materials and other potentially required accessories.
8. The layout of the piping used for air intake and exhaust must be done in a
way that facilitates smooth travel and natural ow.
9. A pressure drop calculation is an acceptable method for evaluating
theoretical draft, but is not enough information to fully validate
combustion air intake and ue gas exhaust vent systems. The designer and
installer must use good practice and remain cognizant of important factors
that cannot be captured by a pressure drop calculation such as local code
requirements, accessibility for inspection and maintenance, aesthetic
concerns, ue gas recirculation, stagnant vapor plumes, prevailing wind
direction, nearby mechanical equipment and other design considerations
1. It is the responsibility of the designer and installer of the venting system to
guarantee the prevention of ue gas recirculation (ue gases being drawn
into a boiler’s combustion air supply, or ue gases moving backward
through an idle boiler).
2. The installation of room 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, resulting in poor combustion.

1. Adequate combustion air and ventilation must be supplied to the boiler
room in accordance with local codes and NFPA54/ANSI Z233.1, Section
9.3, Air for Combustion and Ventilation or CSA-B149.1 for Canada. The
minium net free area requirements in Table 6 may not supersede local and
jurisdictional codes and regulations where there codes and regulations
require an opening of greater net free area. The boiler room must meet the
NFPA criteria for a non-conned space.
2. Verify combustion air is taken from the outdoors and not from the inhabited
or occupied spaces within the building. Ensure space and nearby products
are evaluated for the potential of combustion air contaminants. See Table 5.
3. For installations providing two permanent openings directly
communicating with the outdoors, the minimum net free area of each
opening is 1 in per 4,000 BTU/hr of the total input capacity of the
combined burners located in the boiler room. Ensure a high opening
commences within 12 inches of the ceiling, and a low opening commences
within 12 inches of the oor. See Table 6.
4. For installations providing a single permanent opening directly
communicating with the outdoors, the minimum net free area of each
opening is 1 in per 3,000 BTU/hr of the total input capacity of the

same space such as water heaters, generators, air compressors, or other
boilers. The boiler room must have an opening or openings not less than
the total net free area required for all types of equipment.
7. Consider the blocking eects of louvers, grills, and screens on the net free
area of each opening. Ensure ventilation openings are unobstructed.
8. Ensure there is not negative pressure in the boiler room. The boiler room
pressure must be neutral relative to the outdoors.
9. Where mechanical combustion air supply systems are used, such as a
combustion air supply fan or a motorized louver, they must be interlocked
with the boiler control panel to prove operation prior to burner ignition
and during burner operation. Where manual louvers are used, ensure they
are fully open prior to operating the boiler(s).
10. A 90˚ elbow is recommended on the air inlet to prevent debris falling into
the cabinet.
Air Piped From Outside Boiler Room
The combustion air supply can be piped directly to the air inlet of the boiler.
Adhere to the following for installation:
1. An adapter (not supplied with boiler) may be required to connect the
boiler air inlet to the combustion air piping.
NOTE:The weight of combustion air intake piping must not be supported by the
boiler. Ensure air intake piping is externally supported on hangers or straps.
2. The air intake must be piped out of the building if the boiler room contains
contaminated air.
3. The combustion air intake termination must be located as to not be
subjected to the intake/exhaust of other mechanical equipment such as
other fuel-red heating equipment, loading docks, generators, and air
handling systems.
4. Ensure the boiler room air is maintained at a dew point temperature
below the temperature of the combustion air. Failure to provide adequate
ventilation or control dew point temperature may result in water or ice
build-up on the combustion air piping, leading to increased maintenance
or damage to boiler components.
2-24
5. The air intake system must be designed to prevent any moisture from
draining to the boiler. Slope the air intake duct down away from the boiler.
6. Air Intake pipes and ttings shall be Schedule 40 PVC pipe or smoothwalled 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.
7. 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 aects the joint
strength or chemical resistance of the cement. The cement must not show
gelation, stratication, or separation that cannot be removed by stirring.
8. Adhere to procedure for cementing joints (per ASTM D2855).
9. Avoid sidewall exhaust with roof terminated intake air. This may lead to
reverse stack eect when the boiler is idle.

Exhaust Venting
! WARNING
Fulton accepts no liability for installation
of any venting, including the selection of
venting materials. Maximum allowable
ue gas operating temperatures may
vary by manufacturer. Consult the
venting supplier for maximum allowable
temperatures.
The Endura is equipped with a vent connection at the lower rear of the boiler.
Adhere to National Fuel Gas Code (ANSI Z223.1) and 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 UL 1738, and guaranteed appropriate for the application by
the manufacturer and supplier of the venting. It is also acceptable to vent
the Endura as a Category II condensing, negative pressure, for which an
upsized diameter is typically required.
2. Do not use boot tees or bullhead tees. Use inline condensate drains in
place of boot tees at the bottom of a vertical rise.
3. Barometric dampers are physically open to the mechanical space.
When used in a condensing boiler application with negative pressure
(Category II) exhaust vent, the design must prevent ue gas condensate
from draining down the outside of the stack or dripping into the space.
Barometric dampers must never be used in a positive pressure exhaust or
direct vent sealed combustion application.
4. Where allowed by the authority having jurisdiction (AHJ), the exhaust may
be vented using Schedule 40 PVC, Schedule 40 CPVC, or Polypropylene
listed and labeled to UL 1738 or ULC S636. If venting with Schedule 40
PVC, at minimum the rst 8 inches of pipe must be Schedule 40 CPVC, see
Figure 19 and Table 8. Do not insulate plastic exhaust vents. Canada only:
Schedule 40 PVC, CPVC, or Polypropylene vent materials must be listed and
labeled to ULC S636.
5. Refer to Table 7 for acceptable vent materials and temperature limits. The
use of cellular core PVC/CPVC or Radel® (polyphenylsulfone) in venting
systems is prohibited.
Questions? Please Contact Your Local Manufacturer’s Representative
6. A stainless steel adapter (not supplied) specic to vent manufacturer type
and material will be required. Consult the venting supplier for guidance.
See Figure 19.
7. Adequate provision must be made to support the weight of the exhaust
venting. It cannot be supported by the boiler exhaust connection.
8. Following the venting manufacturer’s instructions for installation of
exhausting venting.
9. Horizontal vents must allow for ue gas condensate to drain back to the
boiler exhaust connection with a minimum pitch of ¼” (7 mm) per foot
(300 mm) run. Failure to do so can create a condensate pocket, which can
result in an inoperative boiler. There must be no low spots in the exhaust
vent, as this can also result in a condensate pocket. A high spot acceptable,
provided the minimum pitch is maintained in both directions.
10. The boiler control will automatically disable and reset the burner should
the ue gas temperature exceed the stack limit setting. The factory default
stack limit setting is 200°F; this may be eld adjusted (See Operation) for
installations utilizing a material in Table 7 approved for higher ue gas
temperatures. To prevent the likelihood of automatic resets caused by
approaching venting material limitations, it is suggested to use AL 29-4C,
316L, or Polypropylene in applications where return water temperatures
can exceed 140°F (165°F ue gas temperatures).
11. If stack drains are installed, they must be pitched back to the boiler and
combined with the boiler ue gas condensate drain piping into the
condensate drain trap.

Common Venting Layouts for Endura
It is possible to combine the air intake and/or exhaust
venting of multiple Endura boilers. The pressure drop across
the entire common system, the combined total of both air
intake and exhaust, must comply with the draft pressure
requirements for an individual boiler, see Table 4.
Refer to Figure 20 and 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 backow of exhaust gases
through idle boilers.
2. Endura boilers are not approved for common venting
with other equipment. Examples include steam boilers,
water heaters, generators, and other types of Fulton
equipment.
3. A constant diameter common header is recommended.
Do not use the static regain method.
4. A minimum 1/4” rise per foot run is required for
horizontal sections.
5. Where individual stacks transition into the common
header, a 45 degree reducing tee or elbow in the
direction of ow is recommended. Straight-in or 90
degree tees must not be used.
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:
` COMMON VENTING EXHAUST BACKFLOW PREVENTION
1. When combining the exhaust vents of multiple Endura
boilers, the system must be designed to guarantee
ue gas and exhaust will not backow through an idle
boiler. This generally requires appropriately sizing the
common exhaust vent to maintain a slight negative
draft pressure throughout all operating conditions.
Alternative solutions may be considered provided
the solutions to prevent ue gas recirculation (FGR),
exhaust backow, and unacceptable draft pressures
have been thoroughly evaluated by the venting
designer and supplier.
2. It is recommended to install individually piped intake
vents or use neutral pressure boiler room air with a
common exhaust system. For common exhaust vent
applications also combining combustion air intake (CAI)
vents into a common pipe, it is necessary to size the
common CAI pipe for a negligible pressure loss.
3. Precautions must be taken to ensure that the draft
pressure at each boiler is maintained within in the
required range (refer to Table 4) throughout all
conditions while also maintaining a slight negative
draft pressure in the common exhaust header. Consider
all possible operating conditions of the exhaust system
specic to the application, including:
Low and high ue gas temperatures Low and high ambient air temperatures All boilers operating at their maximum input
rating capacity
One boiler in the system operating at the low re
position
No boilers on, pre-purge and ignition
4. Consider the natural draft eects associated with
vertical exhaust vent rise. Over-draft control accessories,
such as modulating stainless steel dampers, may be
required to mitigate a negative pressure exceeding the
value in Table 4. An undersized common exhaust vent
or pressure drop due to the horizontal run can create a
positive pressure common exhaust situation which may
require a mechanical draft assist (exhaust fan) system.
5. If the common exhaust conguration does not allow
for a stable negative pressure under all operating
conditions then a mechanical draft assist system, such
as a variable speed exhaust fan, may be required.

Venting Terminations
Adhere to National Fuel Gas Code (ANSI Z223.1) and the
following for installation:
1. Do not terminate the venting in an enclosed area. Care
must be taken when selecting the orientation of the
terminations.
2. 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 22, 23 and 24). The air space clearances should be
observed to joists, studs, sub oors, plywood, drywall or
plaster enclosures, insulating sheathing, rafters, roong,
and any other material classed as combustible.
3. To prevent the possible re-circulation of ue gases,
the vent designer must take into consideration such
things as prevailing winds, eddy zones, building
congurations, etc. Fulton cannot be held responsible
for the eects such adverse conditions may have on
theoperation of the boilers.
4. The required minimum air space clearances also apply
to electrical wires and any kind of building insulation.
5. Listed termination parts must be used.
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.
Roof Vent Termination
Adhere to the following for installation (see Figure 22 and 23):
1. 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.
2. When installing inlet and exhaust terminations above
the roof, the exhaust outlet must be installed 4 feet
(1.22 m) minimum above and 4 feet (1.22 m) minimum
downwind from air supply inlet to prevent exhaust
recirculation.
6. 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.
7. It is recommended to install a mesh bird screen, with
minimum 1/2” by 1/2” openings, at the combustion
air intake termination. Climates subject to extreme
cold may require alternate congurations to provide
an increased surface area, such a cylindrical screens.
Consult your venting supplier for recommendations.
8. It is important to locate the exhaust termination 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.
9. Fulton does not recommend the use of rain caps on the
ue termination. Rain caps contribute to ice buildup,
stagnant vapor plumes, ue gas recirculation (FGR) and
additional vent pressure loss. See Figure 22 and 23.
Wall Thimble Installation
Adhere to the following for installation (see Figure 21):
1. Insert the thimble through the wall from the outside.
2. Secure the outside ange to the wall with nails or
screws, and seal with adhesive material.
Side Wall Vent Termination
Adhere to the following for installation (see Figure 24):
NOTE: The vent termination is joined to the vent pipe outside
the wall. Use the same joining procedures for vent pipe and
ttings.
1. 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. 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).
2. 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).
3. The termination of the vent system shall not be located
over trac areas such as public walkways, or over
an area where condensate or vapor could create a
4. Do not terminate below operable windows and building openings unless
exception is granted by the authority having jurisdiction.
5. The vent terminations must be at least 4 ft (1.22 m) horizontally from
electric meters, gas meters, regulators, and relief equipment.
6. When installing inlet and exhaust terminations on the same wall, the
exhaust outlet must be installed 4 feet (1.22 m) minimum above and 10
feet (3.05 m) minimum downwind from air supply inlet to prevent ue gas
recirculation.
7. Under certain wind conditions, some building materials may be aected
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.
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 deciency, 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.
Assembly of Fulton 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.
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: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 conrm 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
specications. 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, including threaded and anged factory
connections which may loosen during shipment.
11. Pneumatically test the piping (at 15 psig [103 kPa]maximum) prior to lling
the systems.
12. Check bolts and connections for tightness after the rst heat up cycle.
Retorquing may be required.

from a neighbor’s phone. Follow the
gas supplier’s instructions. • If you
cannot reach your gas supplier, call
the re department.
A qualied installer, service agency
or the gas supplier, must perform
installation and service.
Do not use this boiler if any part
has been under water. Immediately
call a qualied service technician to
inspect the boiler and to replace any
impacted part of the control 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.
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 rell/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
valve), shuto valve in cold water ll line, and shuto valve in return line.
9. Make sure the following are closed - all drain cocks, the vent on the
combination shuto-purge valve, & all manual vents. Reset zone valves to
normal mode of operation and turn o power to boiler.
10. Open fuel shuto valve, allowing fuel to ow to 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.
Commission The Boiler
Adhere to the following when commissioning the boiler:
1. Verify with authorized personnel that the gas lines have been purged. Do
not proceed without verication.
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-specic burner and control schematics, and follow
appropriate instructions.
NOTE:Warranty coverage is valid only if the boiler is commissioned (“started
up”) by a factory authorized service technician with a valid Endura Certicate of
Authorization. The commissioning agency must successfully complete and return
the Fulton Installation and Operation Checklist report (“Start-up Report”) to
Fulton within twelve (12) weeks of start-up. Combustion and maintenance records
detailing compliance with the Installation, Operation and Maintenance manual
must be produced for warranty consideration.
System Design and Boiler Operation
The Endura boiler must be installed in an appropriately designed system per
Installation section of this manual.
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.
4 CAUTION
Do not use this equipment if any part
has been under water or subjected
to heavy rains/water. Immediately
call a qualied 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.
The thermal shock warranty does not
cover damage due to cyclic fatigue.
1. The boiler shall be operated/controlled to ensure the boiler does not cycle
more than 12,000 times per year and the temperature dierential across
the boiler does not exceed 100°F (56°C).
2. Site specic conditions including combustion air temperature, elevation,
fuel temperature, caloric value of the fuel, combustion air system design,
exhaust system design, voltage uctuations and other factors will impact
boiler performance.
3. Performance factors aected may include but are not limited to input/
output ratings, eciency, modulation rates and emissions.
4. The Fulton factory Test Fire Report should be used as a point of reference
in commissioning settings for the boilers in the eld, however a factory
certied service technician should account for all site conditions when
nalizing operational settings.

When commissioning is complete,
SOLA control must be placed into
automatic mode.
Commission The Boiler: Zero Governing Gas Valve
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.
Refer to Table 10 and the factory test re report for combustion settings.
NOTE:Perform the following steps for eld commissioning with the Gas Valve
(Figure 27).
NOTE:A properly calibrated combustion analyzer will be required when making
changes to the 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. Use the Test Fire Report to verify the factory low re RPM setting. Input
this setting into the SOLA manual ring rate (Figure 32). Once the boiler
is at this RPM check combustion. If combustion is within the acceptable
O2 range stated in Table 9 or Table 10, increase at 1,000 RPM increments
to the high re RPM rate. The high re RPM rate is listed on the Test Fire
Report and in the SOLA under “Modulation Conguration”, CH Maximum
Modulation Rate. 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 eect high re, and vice versa. It is recommended to adjust
high re combustion prior to making any adjustments at 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 26) in the
negative (-) direction. To decrease O2 level, turn the Valve Adjustment
screw in the positive (+) direction. 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 Oset Adjustment (allen screw on the side of the valve, see
Figure 26) will need to be rotated. To increase O2 turn the Valve Oset
Adjustment screw in the negative (-) direction; turn in the opposite
direction to decrease O2.
3-4
7. When turning the valve oset adjustment go half past the desired setting,
then turn the valve oset adjustment back to arrive at the desired setting.
Example: To turn the valve oset adjustment a quarter turn positive,
proceed a half turn positive, then turn adjustment back a quarter turn
negative. The net result is a quarter turn positive.
8. Changes to either the Shutter or Oset Adjustments on the valve will alter
combustion throughout the range. Once combustion setup is completed
at low and high re, perform the following steps to verify O2 repeatability:
A. Ramp the boiler from low re RPM to high re RPM.
B. From the high re RPM, ramp back to the low re RPM, record
combustion O2%.
C. Turn the boiler o.
D. Turn the boiler on and set to the low re RPM rate.
E. Verify combustion O2% at low re is consistent with the value recorded
in Step B. If it is not, reference Valve Oset Adjustment in Step 6 for low
re RPM adjustments.
9. Verify combustion settings are in the range specied by Table 9.
NOTE:Proper set up of the Ignition Enrichment gas is crucial to the light-o
of the boiler and requires verication in the eld during initial commissioning.
Fulton recommends the Ignition enrichment setting is veried during the yearly
preventative maintenance.
10. Once nal eld combustion is completed at low and high re, the ignition
enrichment setting requires verication. Use the factory Test Fire Report to
determine the factory light o RPM fan speed setting. Input the light o
RPM into the SOLA “manual ring rate” screen (Figure 33).

General
Your Endura boiler has been designed to provide years of trouble free
performance. To ensure continued safety and eciency of the boiler, please follow
the maintenance and inspection directions outlined in this section of the manual.
Daily, Weekly and Monthly Maintenance and Inspection are considered good
practice for any boiler, and are applicable to the full line of Endura boilers. It is
also good practice for any boiler installation to perform a thorough review of
the overall system on a regular basis, and after any maintenance procedures.
Any potential issues should be noted and followed up on to ensure safety and
reliability of all relevant equipment. System review items may include:
Looking for discoloration of any painted equipment, boiler jacket panels,
and/or insulation used in system piping.
Carefully checking for gas leaks using a combustible gas detector during
commissioning and regular inspections; a GASMate® 0119 or equivalent is
recommended. This includes, but is not limited to: Gas delivery system, gas
train ttings, pressure switches, gas valves, regulators, conduit connections
to gas devices, and pre-mix delivery components.
Looking for evidence of leaks including the air intake/exhaust systems, boilers,
hydronic system piping, pumps, valves and other system components.
Once boilers are running, making sure there are no ue gases around the
boilers, or in the boiler room.
NOTE:Combustion analysis and adjustment schedule can vary based on boiler
application and seasonal conditions. Biannual or quarterly adjustment may be
optimal in some applications—for example, systems operating as both winter
heat and summer reheat.
Daily Inspection Schedule
Daily inspection must include the following:
1. Observe operating temperature and general conditions.
After initial start-up by qualied
personnel, linkage, control settings,
and fuel pressures should not be
readjusted.

not obstructed.
3. Make sure the boiler area is free and clear of any combustible materials,
including ammable vapors and liquids.
Weekly Maintenance Schedule
Weekly maintenance must include the following:
1. Observe the conditions of the main ame. Correct fuel/air adjustment is
essential for the ecient and reliable operation of this boiler. If an adjustment
to the combustion is necessary, the ue gas composition should be checked
with a carbon dioxide (CO2) or oxygen (O2) analyzer to set conditions.
Monthly Maintenance Schedule
Monthly maintenance must include the following:
1. Test high-limit control by reducing setting below the operating temperature;
burner should shut o. After readjusting the setpoint, reset the control.
2. Test operating temperature control by reducing temperature setting as
necessary to check burner operation.
3. Check ue gas temperature at outlet. If there is a temperature increase over
previous readings, the probable cause is soot or water-scale build-up on the
tubes. Consult Fulton Heating Solutions immediately if there is a concern.
4. Test low gas pressure switch and high gas pressure switch utilizing the
procedure in Operation section of this manual.
5. Inspect the combustion air inlet lter. If dust, lint or debris has accumulated,

prevent unltered air leaking into the cabinet.
5. Verify the burner head to ignitor gap with the use of
a borescope. For borescopes equipped with a mirror,
insert the end straight down into the combustion
chamber at least 6” (152 mm) to view the ignitor from
the side and bottom. For borescopes not equipped
with a mirror, bend and angle the camera to obtain a
necessary view.
6. Visually verify the ignition position relative to the
burner head.
The negative electrode must not be touching or
resting on the burner head.
The two electrodes must not be touching. See
Figure 76.
The burner to ignition gap tolerance is 0.0625”
(1.588 mm) to 0.125” (3.175 mm), it should appear
visually similar to the electrode gap. See Figure 76.
7. Remove the borescope and reinstall the heat block,
ame scanner, and sight glass. Apply new thread
sealant to all applicable connections.
