BOILER CLEARANCES
all dimensions in mm (in.)
The following minimum clearances must be maintained for operation
and servicing.
Additional space will be required for installation, depending upon site
conditions.
Side and Rear Flue
a
Provided that the flue hole is cut accurately, e.g. with a core drill,
the flue can be installed from inside the building where wall
thicknesses do not exceed 600mm (24"). Where the space into
which the boiler is going to be installed is less than the length of
flue required the flue must be fitted from the outside.
Installation from inside ONLY
b
If a core boring tool is to be used inside
the building the space in which the boiler
is to be installed must be at least wide
enough to accommodate the tool.
LOCATION OF BOILER
The boiler must be installed on a flat and vertical wall, capable
of adequately supporting the weight of the boiler and any
ancillary equipment.
The boiler may be fitted on a combustible wall and insulation
between the wall and the boiler is not necessary, unless required
by the local authority.
The boiler must not be fitted outside.
Timber Framed Buildings
If the boiler is to be fitted in a timber framed building it should be
fitted in accordance with the British Gas publication 'Guide for
Gas Installations in Timber Frame Housing', reference DM2.
Front clearance: 450mm (17
3/4
") from the
front of the boiler casing. The minimum
front clearance when built in to a cupboard
is 5mm (

")
