FLEET W series 500001211/F
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’ is a gas fired, fully modulating, pre-mix,
condensing, room sealed central heating / hot water
boiler, comprising of 8 models covering the range of 40 -
150kW output
Where the application requires more than a single boiler
output, cascade systems can be supplied in a modular
format, with a maximum of four modules sharing a
common flue and 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.
Individual modules can be room sealed using
appropriate concentric or 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
B
23
applications, the Hamworthy boiler
connection kit 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
or un-vented (pressurised) heating system - refer to
Appendix E. 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.

analogue control input compatibility.
1.8
Options - refer to individual kit instructions for details
1.8.1
Optional frame set and water pipe work kits are
available for single and 2 boilers, which can be connected
up to cater for upto 4 boilers. 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 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.
