1.7 BOILER DIMENSIONS, SERVICES & CLEARANCES
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
boring tool or hole cutter the flue can be installed from inside
the dwelling where wall thicknesses do not exceed 600mm.
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 or hole cutter is to be used inside the
dwelling the space in which the boiler is to be installed
must be at least wide enough to accommodate the tool.
In either of the above cases safe external access is
required to allow the addition of sealant to seal the flue to
the aluminium flue collar (RSF 060).
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 provide
the 100mm clearance required for
servicing.
Max 30kW
Max 24kW
2. For flue lengths requiring “D” pack extensions (RSF 341), the flue must incline by 26mm per 1 Metre of flue length.
