*NOTE: The boiler can be operated with a
clearance of 5mm at the right. This is also
sufficient for routine maintenance.
However a clearance of 20mm is required
if it is necessary to remove the secondary
heat exchanger. This should be
considered when siting the appliance and
in the event of any subsequent alterations
in the area of installation
