PREPARATION OF THE WALL

2.3.1 The appliance and flue pipes must be installed at right angles to the
mounting wall. The appliance itself should be installed vertically against
a flat wall. Where an uneven wall surface is found, appropriate action
should be taken to ensure that the appliance is not stressed or does not
distort when installed.
Ensure that the floor surface onto which the appliance is mounted onto
is flat. The minimum height from the floor to the centre of the flue is
shown on figure 6 overpage.
