BOILER CLEARANCES -
UNVENTILATED COMPARTMENT
The diagram opposite shows the minimum
space required to install and service the boiler
600mm
inside an unventilated compartment.
* Space required for unventilated areas with
a removable door or panel, but 600mm to a
fixed surface for servicing.
** This space can be reduced to 50mm for
one side only as long as both side clearances
add up to the total of both the side
measurements shown, or more.
Two examples are shown opposite, refer to
100mm**
the 'Installation, commissioning and servicing
instruction manual' for further information.
Do not add cupboards, shelves etc. to restrict
the space around the boiler.
VENTILATION
This is a room sealed boiler and does not
require any air for combustion from inside the
property.
In spite of the requirements of BS 6798 and
BS 5440 there is no need for ventilation
openings to be provided in the compartment
because of the low heat loss from the boiler
casing, if the clearances shown are maintained.
BOILER CLEARANCES -
AIRING CUPBOARD
If the boiler is fitted into an airing cupboard
then the diagram opposite shows the minimum
600mm
clearances required around the boiler and
also the clearances for any shelf constructed
above the boiler.
If a compartment is built around the boiler
100mm
after installation, then the compartment must
be separated from the boiler space by a non-
combustible partition as described in BS 6798.
WARNING
Do not operate the boiler if the flue terminal
fitted on the outside wall or roof is obstructed
or damaged.
PUMP ANTI-SEIZURE
If there has been no heating demand for 24
hours, the boiler will run the system pump for
100mm
a few seconds. This is to reduce the possibility
of pump seizure during long periods of
inactivity which are usually more frequent
during the summer months.
