The cupboard footprint needs to be at least 650mm square for units
up to 300 litres, 730 mm for 400 litre units.
The base chosen for the cylinder should be level and capable of
supporting the weight of the unit when full of water as shown in
General Data. The discharge pipework for the safety valves must
have a minimum fall of 1 : 200 from the unit to a safe discharge point.
All exposed pipework and fittings on the cylinder should be insulated, and
the unit should NOT be fixed in a location where the contents could freeze.
In replacement systems, whenever a boiler or hot water storage vessel
is replaced in an existing system, any pipes that are exposed as part of
the work or are otherwise accessible should be insulated as recom-
mended for new systems, or to some lesser standard where practical
constraints dictate.
