FLEET H series 500001216/D
1.0 INTRODUCTION
1.1 This boiler must be installed by a competent
person . All installations MUST conform to the relevant
Gas Safety and Building Regulations. Health & Safety
requirements must also be taken into account when
installing any equipment. Failure to comply with the
above may lead to prosecution.
1.2 This boiler is intended for use on Group H Natural
Gas (2nd Family) .The firing information is to be found in
Appendix ‘A’. Boilers
MUST NOT use gas other than
that for which they are designed and adjusted.
1.3 The ‘Fleet’ H series boiler is a floor standing, gas
fired, fully modulating, pre-mix, condensing, room
sealed central heating / hot water boiler, comprising of 5
models covering the range of 175 - 350kW output
Where the application requires more than a single boiler
output, cascade systems can be supplied in a modular
format, configured horizontally up to 4 boilers wide
sharing common water pipe work - optional HHL supply.
See figures 3.2.1 - - 3.2.5 , for typical schematic layout.
1.3.1 Using the latest gas / air ratio control technology
it is able to provide clean efficient operation across a
large output range via the Merley Boiler Sequence
Controller, ideally suited to installations that do not have
a dedicated controls installation.
The Merley control provides cascade management for
multiple boilers and simultaneous management of three
different circuits operating at different temperatures.
(radiators, dhw & under-floor heating) .
Operation is initiated and controlled by a LMU boiler
management system with a user interface LCD display
for accessing and changing boiler parameters.
1.3.2 Each of the boiler models is designed for direct
connection to a plastic flue system - HHL supply. The
Technical Data for the various arrangements is given in
Appendix C.
The flue outlets from more than one unit may be
connected to a single chimney, or individual modules
can be room sealed using appropriate twin duct
systems (HHL supply) up to a maximum length - refer to
Appendix C
No draught diverter is fitted to the boiler nor is a fixed
diverter required in the flue system.
However, for B23 applications, the hamworthy air inlet
filter MUST be used to provide the correct clean air
supply to the boiler. Refer to Appendix C
1.3.3 The Fleet is intended for the heating of
Commercial and Industrial premises, or large residential
properties. It may also be used to supply hot water for
these premises via an indirect cylinder.
1.3.4 The Fleet has a low water content and is fitted with
an integral circulating pump to ensure that water flow
rates are achieved - refer to Appendix E for available
pump head to the system.
Accordingly in a primary circuit - refer Appendix E there
is no need for a primary circulating pump.
1.4 The boiler is suitable for connection to an open vented
and un-vented (pressurised) heating system, care must
be taken to ensure all extra safety requirements are
satisfied and that the relevant interlocks will shut the boiler
(s) off should a high or low pressure fault occur.
The pressurisation unit must also incorporate a low level
water switch which protects the water pumps and will
directly or indirectly shut down the boiler plant should a
low water condition occur. Consideration should also be
given to the maximum working pressure of the boiler as
given in Appendix ’E’. Consult Hamworthy Heating
Technical Department for help or assistance if in doubt.
1.5 The Fleet boiler is not suitable for direct connection to
domestic hot water supplies.
1.6 BOILER MODELS
Single models
Fleet F175H - output 175kW
Fleet F200H - output 200kW
Fleet F250H - output 250kW
Fleet F300H - output 300kW
Fleet F350H - output 350kW
1.7 Each Fleet boiler is supplied with a vfc contact output
for Normal Run and General Fault outputs, and 0~10v
analogue control input compatibility.
1.8 Options - refer to individual kit instructions for details
1.8.1 Optional water pipe work kits are available for
horizontal single boilers up to 4 boilers wide,.These kits
are free-standing allowing installation to the system prior
to installing the boiler and incorporate all necessary
valves, inter connecting pipework, and flow and return
headers. Refer to individual kit instructions 500005133 for
details.
1.8.2 Controls peripherals
The LMU boiler management system has the potential to
accept the following control options:
1.8.2.1 External sensor
Allows direct weather compensation on an individual
boiler. Not to be used for multiple boiler systems.
1.8.2.2 Clip in module (LPB Bus)
Allows communication with multiple boilers under the
control of a Merley Boiler Sequence Controller.
1.8.2.3 Merley Boiler Sequencer Controller
Allows cascade management of up to 16 boilers, and
interface with a BMS system.
