Notes
1 The position of the tundish, discharge pipe size and termination point will need
to comply with the requirements set out on pages 12 and 13 of this manual and
Building Regulations Approved Document G3.
2 The primary expansion vessel, gauge and safety valve should normally be fitted
on the boiler flow in the appliance cupboard where the gauge can be seen when
operating the filling loop. There shall be no restriction or valves fitted in the
pipework between the boiler and the primary system safety valve.
3 If the primary pipework from the boiler to the safety valve is more than 6 metres,
we recommend that the safety valve is fitted on the boiler flow adjacent to the
boiler (a pressure gauge must still be visible when operating the filling loop).
4 The potable water expansion vessel should be fitted on the mains cold water supply
adjacent to the Ideal System Ready appliance. No valves shall be fitted between
the inlet group and the appliance.

Model Selection Data/Cupboard Sizes
Use the model selection guide on page 10 to
choose the appliance size.
A 700 wide x 700mm deep cupboard is
recommended as the minimum size for
the system ready cylinders. The height is
determined by the model size selected, and
sufficient room should be allowed for the siting
of the expansion vessels.
A minimum 600mm deep access is required to
the front of the appliance and expansion vessels
to allow subsequent maintenance/replacement
of the immersion heater.
