WARNINGS
SAFETY
The instructions provided for the operation and maintenance of the boiler MUST be observed. Failure to do so could result in
damage to the heater and serious personal injury.
!
WARNING
Do not try to do repairs or any other maintenance work
you do not understand. Obtain a service manual from
Fulton Ltd or call a Fulton service engineer.
It is the responsibility of the installer to ensure all parts
suppliedwiththeboilerarettedinacorrectandsafe
manner.
Understand the electrical circuit before connecting
or disconnecting an electrical component. A wrong
connection can cause injury and or damage.
A defective boiler can injure you or others. Do not
operate a boiler which is defective or has missing
parts. Make sure that all maintenance procedures are
completed before using the boiler.
Do not change the boiler fuel without consulting the
boiler manufacturer.
LIFTING EQUIPMENT
Make sure that lifting equipment complies with all local
regulations and is suitable for the job. You can be injured
if you use faulty lifting equipment. Make sure the lifting
equipment is in good condition.
Operating the boiler beyond its design limits can damage
the boiler, it can also be dangerous. Do not operate the
boiler outside its limits. Do not try to upgrade the boiler
performancebyunapprovedmodications.
Non-approvedmodicationscancauseinjuryand
damage. Contact your Fulton dealer before modifying
the boiler.
Only qualied persons should be allowed to
operate and maintain the boiler and its equipment.
Boilers should always be drained through an approved
blowdown vessel.
The installation of gas appliances including the
uesystemshouldonlybecarriedoutbyGasSafe
registered engineers.
Steam boilers have high temperature surfaces, that if
touched may cause serious burns. Only competent and
qualiedpersonnelshouldworkonorinthelocalityof
a steam boiler and ancillary equipment. Always ensure
theworkingareaandoorareclearofpotentialhazards,
work slowly and methodically.
DoNOTstoreinammablematerialsneartheboiler.
The importance of correct boiler water and feedwater
cannot be over emphasised, see the relevant section in
this manual.
!
CAUTION
Obey all laws and local regulations which affect you and
your boiler.
LOW FEEDWATER TEMPERATURE
Low feedwater temperature can result in thermal shock
to the boiler pressure vessel. Return the maximum
amount of condensate and if necessary preheat the
feedwater. If in doubt consult Fulton Ltd.
WATER SOFTENER and CHEMICAL TREATMENT
The chemicals required to operate the water softeners
and chemical treatment plants CAN BE SUPPLIED by
Fulton Ltd.
It is the responsibility of the operator to ensure adequate
supplies of chemical are available at all times
(including commissioning). Costly repairs could be
required should the plant operate without chemicals or
the wrong dosage of chemicals.
HYDRAULIC TEST - RISK OF BRITTLE FRACTURE
Hydraulic testing requires specialist equipment and
is normally only required by engineering surveyors /
inspectors. In order to ensure the material/ pressure
vessel does not suffer from brittle fracture, hydraulic
testing should not be carried out below 7 °C.
!
WARNING
DANGER FROM INCOMPLETE COMBUSTION
The importance of correct burner adjustment to achieve
lowemissions,safe,cleanandefcientcombustion
is paramount. Poor combustion, where unburnt gas
forms carbon monoxide is both a health hazard, and
the potential risk to the boiler from overheating, caused
byre-burningoftheunburntgasinthesecondaryue
passes.
Prior to the commencement of any work requiring the
removal of cover plates and the opening of control panel
box, the electrical supply to the boiler must be isolated.

2.8 STEAM SAFETY VALVE
Safetyvalvesarefactoryttedandpre-set,theyMUSTNOTbeadjusted.Thedischargeoutlet
should be piped to a safe discharge point and the piping so arranged that any condensate
trapped in the pipework will drain away from the valve.
Note: Safety Valve Outlet connections should be piped two sizes larger than the inlet connection size, this will
ensure there are no accumulation issues.
a) The lift pressure is indicated on the safety valve (do not adjust).
b) Thesafetyvalvettedtotheboilerisdesignedtopreventtheboilerexceedingitsdesign
pressure.
c) Any system connected to the boiler not capable of accepting boiler pressure must be protected
by a separate safety valve set to the required pressure.
WARNING
Factory tted safety valves are pre-set to protect the boiler only and must not be used to protect any
other items not capable of accepting boiler pressure.

2.9 WATER SUPPLY
Figure. 8 - Boiler Feedwater Inlet Valve
The quality of the feedwater will affect the life and performance of a steam boiler.
Steamisproducedbyheattransferfromtheheatsourceintothewaterconnedwithintheboiler
cylindrical shell, by the passage of hot gases through the furnace and tubes. It should be noted
that solids entering the boiler with the feedwater can rapidly concentrate at areas of high heat
transfer. Such deposits can restrict heat transfer and consequently raise mean metal temperature,
which can cause corrosion and reduce safety margins possibly to the point of failure.
It is therefore strongly recommended that a reputable water treatment specialist is consulted prior
to putting the boiler into service.
Note: See Appendix A - TI-140-Recommended Water Conditions.
WatercharacteristicsaregenerallyasspeciedinBS24861997“TreatmentofWaterforSteam
Boilers and Water Heaters”, Table 2.
Boilers operating in areas with high residual hardness, high levels of Bicarbonate (temporary)
hardnessandlowcondensatereturnrates,willhavedifcultyinmaintainingTotalandCaustic
Alkalinity(TDS)gures,withinthespeciedlimitswhenbaseexchangesofteningisused.
This will result in a tendency of the boiler water to foam causing unstable water level conditions
possibly leading to priming and carry over. In these instances particular care should be taken to
establish a suitable water treatment programme and blowdown schedule in consultation with your
water treatment specialist.
Cold feedwater contains high levels of dissolved oxygen which is highly corrosive when released
within a steam boiler. Always pre-heat the feedwater to 80 °C - 85 °C to reduce dissolved oxygen
to a minimum and prevent thermal shock. Water treatment chemicals should be used to remove
the remainder of the dissolved oxygen.
Failure to do so will result in premature failure of the boiler tubes which will not be covered by
guarantee.

CAUTION
WATER SOFTENER and CHEMICAL TREATMENT
The chemicals required to operate the water softeners and chemical treatment plants
CAN BE SUPPLIED by Fulton. It is the responsibility of the operator to ensure adequate supplies
of chemical are available at all times (including commissioning). Costly repairs could be required
should the plant operate without chemicals or the wrong dosage of chemicals.

2.10.2 OIL SUPPLY
Oil-redboilersaresuppliedwitha
matched, automatic high/low oil burner
suitable for use with 35 SRNI fuel oil.
A single-pipe system can be used where
thesuctionisfullyooded,however,for
systemswhere‘lift’isrequired,itwillbe
necessary to install a two-pipe system.
For more details consult the burner
manufacturer’sinstructionmanual.
The following points should be observed:
a) Alwaysinstallanoillter.
b) Useexiblepipeworkforthenaloil
connections to the oil pump.
c) Fit isolating valves to the pump.
d) Ensure that the supply pipework is
sized to cause a minimum pressure
drop.

Note: Installation will change with the type of
burner tted.
2.10 FUEL SUPPLY
WARNING
Do not change the boiler fuel without consulting the boiler manufacturer.
!
2.10.1 GAS SUPPLY
The gas/pressure requirement varies
according to the burner size and the gas
train selected.
Verify that the type and pressure of the
gas available on the site is suitable for the
burnertted.
If the site gas pressure is too low, it will be
necessarytotagasboostersystem.
Consult Fulton Ltd if in doubt.
To minimise pressure drops, eliminate
