3. BOILER LOCATION
3.1
DIMENSIONS AND MINIMUM
CLEARANCES
The boiler must be installed in minimum
clearances shown to allow subsequent
servicing, and safe operation. However, larger
clearances may be required during installation.
3.2
SERVICE CONNECTIONS
Gas, water, air and flue pipe, condensation,
and electrical connections are as shown in the
diagram below. Gas : 15mm compression.
Flow/Return 0.75 inch BSP male, Gas 0.5 inch
BSP male, PRV 15mm copper pipe and
Condensate 21.3mm plastic pipe .
An optional stand-off frame (part number
Q.28S.0.01.00.0) is also available which
mounts behind the boiler to leave a 50mm
deep space behind the boiler. This is to
permit pipe routing behind the boiler if
required. See Section 2.5 - Optional
Accessories.
3.3
POSITION
The Qudos 28s and Qudos 28sP 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 the Building Regulations
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 28S and Qudos 28SP are classified as IP20 (IPX0) and are
therefore suitable for installation in Zone 3 areas, unless subject to hose down.
