5.0 BOILER ASSEMBLY
5.1 General
Boilers are despatched to site as fully assembled units. The flue header (where applicable) and frame / pipe work
set (where applicable) are the only items that will need assembling on site.
During assembly it is important to take care to prevent damage to the boiler casing.
Boiler positioning must allow the minimum clearances detailed in Section 3.0 to facilitate access for flue and pipe
work connections as well as maintenance. The boiler must be installed on a solid masonry wall using the
mounting bracket supplied. To locate the boiler on the wall, use the wall mounting plate as a guide.

Place the boiler mounting plate on the wall, at a height of approximately 180 cm from the ground to the top
of the mounting plate, using a spirit level to ensure that the plate is horizontal.

Mark the wall plate mounting holes through on the wall.

Drill the holes (10mm Ø) and secure the wall mounting bracket using the fastenings supplied (4 off).
Carefully lift the boiler onto the bracket using the pallet to support the weight of the boiler.
Health and safety. Due to the weight of the boiler, care must be taken when lifting onto the mounting bracket and
HHL suggest the use of a hydraulic or cable genie lift
5.2 Water Connections
The connections provided on the boiler (refer to Appendix E and figure 4.4) are suitable for direct connection to
the system pipe work. However HHL recommend the use of individual isolating valves, which should be fitted to
each module to enable isolation from the system. However, the arrangement must comply with the requirements of
BS 6644.
When installing water system pipe work, it must be self supporting and care must be taken to ensure that undue
stress is avoided on the boiler flow and return connections. It is recommended that unions are fitted local to the
boiler and outside of the casing, to permit future servicing requirements.
Each module is fitted with safety valve rated at 6bar. The valve discharge pipe is routed to the base of the boiler,
where it must be piped to discharge via a tundish (not HHL supply) suitably located for ease of visibility.
It is imperative that a suitable safety valve is fitted to the installation in the event that the system design
pressure is lower than the boiler maximum operating pressure, according to the requirements of BS6644 -
2011
The Fleet is designed to operate at 20°C ∆ T across the flow and return. Should the flow rate drop, the boiler
controls will modulate the burner to maintain 20°C ∆ T. The boiler module is fitted with a single speed circulating
pump and flow is controlled through a balancing valve, which must be checked and set during commissioning. As
a safety precaution, a flow switch is fitted to the boiler heat exchanger to shut the system down in the event of
sudden adverse flow conditions.
Where using Hamworthy Heating Ltd frame set and pipe work kits, assembly of these is detailed in Instruction
Manual 500005132 supplied with kit.
5.3 Flue Connection
5.3.1
The Hamworthy Fleet boiler is designed for use with the following flue systems supplied by Hamworthy - see Appendix C
80/125mm concentric room sealed, balanced flue system for rear/side through the wall discharge.
100/150mm concentric, room sealed, balanced flue system for remote discharge, horizontal or vertical.
100/130 & 150mm separate air and flue ducts, room sealed, balanced flue system for remote discharge.
100/130 & 150mm flue duct, for connection to an open flue (chimney) system.
Flue systems should be designed with reference to BS 5440 part 1 , IGE/UP/10 and Third Edition of the 1956 Clean Air
Act Memorandum.
