The combination boiler must be installed on a flat
vertical wall capable of supporting its weight .
- If the boiler is in a room containing a bath or show-

MUST be designed and constructed specifically for
the purpose. An existing cupboard, or compartment,
may be used provided it is modified accordingly.

must be observed.
- Minimum clearance as stated in the technical data
must be observed.
4.3 FLUE TERMINAL POSITION
- The boiler MUST be installed so that the terminal
is exposed to the external air.
- It is important that the position of the terminal
allows free passage of air across it at all times.
- It is ESSENTIAL TO ENSURE, that products of
combustion discharging from the terminal cannot re-
enter the building, or vehicle, through ventilators,
windows, or other sources of natural air infiltration,
such as other flues etc, with the exception of doors,
but not the opening windows thereof.
- The minimum acceptable dimensions from the ter-
minal to obstructions and ventilation openings is as
follows:
Where the terminal is fitted in a position to which
children, the elderly, or disabled people have access
(less than 1.5m above steps, decking or ground), a
suitable terminal guard should be fitted.
In certain weather conditions the terminal may emit
a plume of steam.
4.4 MINIMUM CLEARANCES
Minimum clearances of 5mm to the front and sides
of the boiler must be observed. However full access
from the front in the form of an opening door, must
be given to allow access to the controls and for serv-
icing.
200mm above the top of the boiler case is required
for the flue assembly.
150mm is required below the boiler to allow easy
access to the gas isolation cock.
