PREPARATION OF THE WALL
2.4.1
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.
2.4.2
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 below.

PREPARATION OF THE FLUE HOLE
2.5.1
Mark the position of the centre of the flue on the inner wall.
2.5.2
Cut hole for outer flue pipe. There are two possible methods to achieve
this, either core drill or via hammer and chisel.
2.5.3
To core drill, proceed as follows :-
Drill a pilot hole through the wall, in position as specified in figure 6.
Using a 6” core drill, drill the flue hole.
To Hammer and chisel, proceed as follows :-
Mark the position of the centre of the flue pipe as specified in figure 6.
Mark the position of the hole around this point.
