General

This boiler is designed to provide central heating from a sealed

water system with a fully indirect cylinder. The pump, expansion

vessel and associated safety devices are all fitted within the

boiler.

Safety valve

The safety valve is an integral part of the boiler and it cannot

be adjusted. The pipe from the safety discharge valve must

discharge safely in accordance with standards.

Expansion vessel

The boiler has an integral expansion vessel with a capacity of 8

litres (1.76 gallons), with a charge pressure of 0.75bar.

i

The heating system volume should be calculated to

ensure that the expansion vessel is suitable, it may

be necessary to add an additional vessel.

- In GB, Guidance on vessel sizing is also given in the current

issue of BS5449 and BS7074 Part 1.
