A flat vertical area is required for the installation of the boiler and it
should be capable of bearing the weight of the boiler when full of water.
These dimensions include the necessary clearances around the boiler for
case removal, spanner access and air movement. Additional clearances
may be required for the passage of pipes around local obstructions such
as joists running parallel to the front face of the boiler.
In the diagram these are MINIMUM recommended dimensions. Greater
clearance will aid installation and maintenance.

Due to the nature of the boiler a plume of water vapour will be dis­
charged from the flue. This should be taken into account when sit­
ing the flue terminal.
