The Qudos 28h and Qudos 28hP Combi are
not suitable for external installation. The
boiler may be installed in any room or internal
space, although particular attention is drawn
to the requirements of the current IEE Wiring
Regulations and, in Scotland, the electrical
provisions of
applicable in Scotland, with respect to the
installation of the boiler in a room or internal
space containing a bath or shower.
Where a room-sealed appliance is installed
in a room containing a bath or shower, any
electrical switch or appliance control, utilising
mains electricity, should be so situated that it
cannot be touched by a person using the
bath or shower. The Qudos 28h and Qudos
28hP are classified as IP20 (IPX0) and are therefore suitable for installation in Zone 3
