WARNING
Blowdown vessels are a potential hazard, possibly fatal
if not properly maintained.
Blowdown vessels reach high temperatures but MUST
NOT be insulated.
Suitable guards should be installed where deemed
necessary to prevent injury.
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.
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.
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.
Never attempt to operate equipment that has failed to
pass all the safety checks.
!
WARNING
When opening any drains on the equipment or piping
system, steps should be taken to avoid scalding/
burningofpersonnelduetohotuids.Whenever
possible, the system should be cooled prior to opening
any drains.
!
CAUTION
Obey all laws and local regulations which affect you
and your boiler.
It is vitally important that the instructions given in this
manual are strictly adhered to. Failure to carry out the
routine maintenance checks could result in a drastic
reduction in the life expectancy of the blowdown vessel.
Blowdown pipework is subject to very rapid increases
in temperature and pressure resulting in high levels of
mechanical and thermal stress.
It is therefore very important that blowdown pipework
is designed correctly using the correct materials, with
suitable brackets to allow for expansion.
The blowdown vessel should never be used for boiler
blowdown when empty.

1.1 GENERAL
Fulton blowdown vessels are designed to BS EN 13445:2014, and have full compliance with
PM60 and the requirements of the European Pressure Equipment Directive 2014/68/EU. They
are intended to reduce the pressure of the blowdown discharge to atmospheric pressure, and to
reduce the discharge to drain to an acceptable temperature.
The energy released by the high temperature and pressure from the boiler blowdown valve(s)
isseparatedintoashsteam,whichisdischargedtoatmosphere,andhotwater/efuentwhich
is discharged to drain. The standing water volume within the vessel is sized to accommodate a
normalblowdown,suchaswouldberequiredtotesttheboilerwaterlevelcontrolsbetweenrst

The blowdown vessel is not intended to cool the discharge to a safe temperature when the boiler
is drained completely at full pressure, or when continuous or intermittent blowdown systems are
used. Under these circumstances an after cooler system should be used together with blowdown
procedures designed to prevent high temperature discharge to drain.
Fulton blowdown vessels are designed for a maximum working temperature of 150 °C and a
minimum working temperature of 5 °C. They are not intended for use in locations where the
ambient temperature is likely to be below 5 °C.

2.3.3 BLOWDOWN INLET CONNECTIONS
2.3.2 DISCHARGE CONNECTION
The discharge from the blowdown vessel should not normally exceed 43 °C when level control
testingbetweenrstandsecondlowwater,orformainblowdownratesnotexceeding5%ofthe
boiler water capacity. Where blowdown rates higher than this are anticipated a cooling system
should be used to prevent excess temperatures being discharged into the drain.
UK - Discharge temperature into public drains must not exceed 43 °C as stated in the Water
Industry Act 1991.
Fulton blowdown vessels are provided with three blowdown inlet connections: 1 x Main boiler
blowdown and 2 x Auxiliary blowdowns. Inlet manifolds are available for multi-boiler application.
In the UK, the permitted arrangements for single and multi boiler blowdown pipework installations
are covered by HSE Guidance Note PM60.
Blowdown pipework should never be smaller than the bore of the blowdown valve supplied with
the boiler.
CAUTION
Discharge temperatures reaching 100 °C could occur in a fault condition (i.e. loss of cooling water
supply) or as a result of human error.
Damage could occur where plastic drainage systems are used.

2.4 PIPING SPECIFICATIONS
For piping the basic considerations are: the design temperature, the pressure retained by the
pipe,theuidinthepipe,theloadresultingfromthermalexpansionorcontraction,impactor
shock loads imparted (such as water hammer, external loads, wind loads and vibration from
equipment).
Adhere to the following:
1. The arrangement of the piping must take into consideration the location of other structures and
equipment adjacent to the piping. The potential for freezing interference and/or damage as a
result of expansion, contraction, vibration, or other movements must be factored.
2. Valvesareusedinpipingsystemstostopandstarttheowofuids,toregulateow,to
preventbackow,andtorelieveexcessivepressurebuild-upinthepiping.Consideration
should be given to the appropriate location and orientation of valves necessary for safe
operation and isolation of the piping.
3. All piping and piping components used should be suitable for the design temperatures,
pressureanduidusedinthesystem.
4. During the installation, ensure that no dirt, water, or residue from welding is left in the system.
5. Expansion joints or properly designed and sited expansion loops should be provided to
accommodate thermal expansion. Thermal expansion should be calculated using the
maximumpossibleutilizationuidtemperature.Steelpipewillexpandapproximately1mmper
meter over 100 °C rise.
6. Supports and anchors must be provided for all pipes, as necessary, to prevent undue stresses
from being placed on equipment, including pumps, valves, and the boiler. Supports and
anchors which will not interfere with thermal expansion should be chosen. The equipment
should never be used or considered as an anchor.
No additional loads should be applied to any factory connection.
7. Gasketsmustbeusedtomakeallangedconnections.Gasketmaterialmustbesuitablefor
usewiththepressure,temperatureanduidinthesystem.Ensurethatallboltsaretightened
evenly and to the torque recommended values provided by the gasket manufacturer.
2.5 INSULATION
Note: It is recommended that for inspection and maintenance, anges, valves and ttings be left uninsulated but
suitably shielded for safety.
Adhere to the following:
1. Blowdown vessels should not be insulated.
2. Equipment should be insulated with material suitable for the application and temperatures
expected.

3.1 VISUAL CHECKS
CAUTION
HYDRAULIC TEST - RISK OF BRITTLE FRACTURE
!
Visually check for leaks paying particular attention to the inspection opening gasket.
When replacing the inspection opening cover it is important that a new gasket is used.
3.2 HYDRAULIC TESTING
Hydraulic testing requires specialist equipment and is normally only required by engineering
surveyors/inspectors. The material that the vessel is manufactured from has not been impact
tested, as it is not a requirement of the construction standard. In order to ensure the material/
pressure vessel does not suffer from brittle fracture hydraulic testing should not be carried out
below 7 °C.
SECTION 3 - MAINTENANCE
CAUTION
Failure to comply with recommended water conditions will invalidate the Guarantee on your
Blowdown vessel.
!
3.3 RECOMMENDED WATER CONDITIONS
For recommended water conditions, refer to manufacturers boiler manual or contact the boiler
manufacturer.
Fulton blowdown vessels are open vented atmospheric vessels with no moving parts or controls.
The only maintenance required is visual checks and an annual statutory inspection.

MAINTENANCE - 3
3.4 BLOWDOWN VESSEL INTERNAL INSPECTION
The hand hole should be removed
after one month of operation and
the interior of the blowdown vessel
thoroughly examined. If scale or
sludge build-up is observed, it should
be removed and the water treatment
supplier advised.
Newgasketsmustbettedevery
time a hand hole is removed (see
Section 3.5 - Fitting New Gaskets To
Inspection Holes).
Subsequent interior examinations
should be carried out on a regular
basis until satisfactory conditions are
observed.

3.5 FITTING NEW GASKETS TO INSPECTION HOLES
3.5.1 IMPORTANT INFORMATION
TheblowdownvesselisttedwithTOPOG-Egasketsinalloftheinspectionholes.Thesegaskets
work very well and millions have been safely used over the last 30 years, however, it is absolutely
essential to observe a few simple rules in order to get the best performance from your installation.
Elastomeric Vulcanizates, which form the basis of TOPOG-E gaskets, undergo degradation
from many sources including heat, oxygen, stress, and overdosing from certain types of water
treatment. This takes the form of material oxidation, hardening/embrittlement and cracking which
may result in gasket failure. Steps must be taken to minimise the effects of such attacks.
Water treatment and oxygen attack can be minimised by ensuring that the gasket is aligned
correctly so that only the extreme edges of the gasket are exposed. If a new gasket leaks after
ttingthisisalmostcertainlyduetoincorrectseatingoralignment.Assuchgasketsarevery
exibleitispossibletocuretheleakbyexcessivetightening,butsuchanactionwillseriously
reduce the life of the gasket and cause problems later.
Gentlewarmingofthevesselatrstuseaftermaintenancewillalsohelptoensurethattherubber
‘cures to shape’. If the rubber post-cures, the elastic memory will be destroyed and any initial
over tightening will cause the gasket to become hardened and embrittled, leading to cracks and
eventual failure.

3.5.2 FITTING PROCEDURE
Drain the vessel completely and examine all inspection holes. If any leakage is evident, proceed
as follows:
1. Disassemble the crab and cover plate and remove the inspection hole assembly.
Remove the old gasket and thoroughly clean the mating faces of the cover plate and vessel
ring.
2. Place the new Topog-E gasket on the cover plate, ensure the gasket is the correct size and is
seatingatagainsttheplate.Donotuseanygrease,lubricantoradhesive.Ifthenewgasket
is not seated properly before the plate is tightened, the gasket may be pinched causing a
failure when the pressure builds up.
3. Position the cover plate in the vessel ring, ensuring that the plate is correctly centred.
An off centre cover plate can concentrate forces on the gasket and cut it in two. The cover
plate may also drag on the vessel hole ring and fail to seal as the pressure rises.
Setthecrabandhandtightenthesecuringnut(s)sufcientlytoprovideasnugt. 
Tighten the nuts a further quarter of a turn using a spanner. DO NOT OVER TIGHTEN.
Note: Ensure the gasket is aligned correctly so that only the extreme edges are exposed to water treatment or
oxygen attack. If the gasket is misaligned, over tightening to seal a leak will not prevent subsequent leakage at a
later date.
4. Ifthegasketleaksduringpressurebuild-up,tightenthesecuringnut(s)sufcientlyonlytostop
the leakage.
Note: New gaskets tted to inspection holes located along the bottom of the vessel are more difcult to install
without leaking. Small particles of scale or sand tend to run down on the mating surfaces after cleaning but prior
to assembling. This condition is likely to have occurred if excess tightening is required to stop a leak before
warming the vessel. In this event, the best course of action is to drain the vessel and repeat the gasket tting
procedure. Failure to do so will severely reduce the life of the gasket.
