installation clearances
For the installation/assembly of the boiler as well as for
carrying out future maintenance tasks, you need the
minimum gaps and installation clearances given below:
Fig. 4.3 Required minimum gaps/installation clearances
It is not necessary to ensure a particular clearance
between the boiler and combustible materials or
components as the temperature of the boiler will always
be less than the maximum permissible temperature of
85 °C at its rated heating output. You need a minimum
of 600 mm clearance in front of the boiler to enable
easy access for servicing. This may be provided by an
openable door.
