1.12 Boiler Clearances
Refer to diagram 1.3.
This boiler must be positioned so that at least the minimum
operational and servicing clearances are provided.
Additional clearances may be required for installation.
If fixtures are positioned next to the boiler ensure access is
provided for pipework installation.
At least a minimum clearance of 300mm from a permanently
fixed surface must be left in front of the boiler for servicing, see
diagram 1.3.
1.13 Room Ventilation
The boiler is room sealed and does not require the room or
space containing it to have permanent air vents.

1 General
Alternatively, an unswitched shuttered socket outlet and 3A
fused 3 pin plug, both to the current issue of BS1363 may be
used provided that they are not used in a room containing a bath
or shower.
Wiring to the boiler must be PVC 85
0
C insulated cable, not less
than 0.75mm

(24/0.20mm).
1.7 Contents of Packaging
The boiler is delivered in one pack with the flue system packed
separately.
1.8 Water System
This boiler may be fitted to an open vented or a sealed water
system.
1.9 Draining Tap
System
A draining tap must be provided at the lowest points of the
system which will allow the entire system and hot water cylinder
to be drained.
Draining taps should be to the current issue of BS2879.
Boiler
A draining point is fitted at the bottom right hand side of the heat
exchanger.
When draining is required cover the controls to avoid water
damage.
If required remove the combustion chamber front cover to
improve access.
1.10 Safety Valve
A safety valve need not be fitted to an open vented system.
1.11 Location
This boiler is not suitable for outdoor installation.
This boiler may be installed in any room, although particular
attention is drawn to the requirements of the current issue of
BS7671 with respect to the installation of a boiler in a room
containing a bath or shower. Any electrical switch or boiler
control utilising mains electricity should be placed so that it
cannot be touched by a person using the bath or shower.
The electrical provisions of the Building Standards (Scotland)
apply to such installations in Scotland.
The boiler must be mounted on a flat wall which is sufficiently
robust to take its total weight.
The boiler may be fitted to a wall made of combustible material.
