BOILER DIMENSIONS, SERVICES & CLEARANCES
all dimensions in mm
The boiler connections are made on the boiler connection tails.
Refer to Frame 23.
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.
Front clearance
The minimum front clearance when built in to a
cupboard is 5mm from the cupboard door but
450mm overall clearance is still required, with the
cupboard door open, to allow for servicing.
*
Bottom clearance
Bottom clearance after installation can be
reduced to 5mm.
This must be obtained with an easily removable
panel, to enable the consumer to view the
system pressure gauge, and to provide the
100mm clearance required for servicing.
