
Feed and Expansion tanks to comply with static height requirements of HSE
document PM5.

Cold feed and open vent pipes to comply with requirements of BS 6644.

The Fleet boiler is fitted with an integral circulating pump, which will shut off
circulation through the heat exchanger 5 minutes after the boiler has ceased firing.
The pump head available from the boiler, is only suitable for circulation in the
primary circuit. This must be acknowledged in the system design.

Pressurised system to comply with BS 7074.

Each module is supplied with a safety valve set at 6barg to protect the boiler.
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 boiler has an aluminium heat exchanger. It is a requirement that the
system & pipe work are flushed at least twice before adding water treatment and
before installing the boiler.
The system water MUST be treated and maintained with an appropriate inhibitor
(eg. Sentinel X100) and the PH MUST be managed between 7 & 8.5. Failure to
observe this requirement will invalidate the warranty.

In hard water areas (>180mg CaCO
3
/litre) precautions such as water treatment are
strongly recommended to prevent the build up of sludge and scale.

Leaks in the system pipe work MUST be fixed to prevent dilution of water
treatment.

Maximum working water pressure is 5.3bar.
