4.6.3 COMPARTMENTS:
Follow the requirements of BS6798 and BS5440 Part 2 and note:
• Minimum clearances must be maintained.
• An access door is required to install, service and maintain the boiler
and any ancillary equipment.
• If the boiler is installed in an unventilated airing/storage cupboard,
there is no requirement to make a partition between the boiler and the
storage space as long as the minimum clearances around the boiler
are maintained.
• Ideally, storage should be below the boiler, where the boiler is
mounted in the upper part of the cupboard, whilst maintaining the
clearances given in tables 13, 14, or 15.
