4.3 PREPARE THE WALL - Figs. 11
If the optional wall jig is used refer to the
instructions supplied with the kit.
1. Decide upon the position of the boiler taking
into account the clearances required for
servicing and the flue terminal position.
2. Tape the template to the wall (ensure it is
level and the right way up) and mark the
position of the holes for the boiler
mounting bracket or, if applicable the wall
jig fixings. If rear exit flue is used, mark the
position of the hole for the flue.
The wall jig is supplied with a pressure
relief valve discharge pipe for use when
the boiler is mounted on an external wall
where the outside is inaccessible, if you
wish to use this pipe - mark it's position.
3. Side exit flue - Continue the horizontal
centre line of the flue across the wall to the
side wall, then along the side wall 140 mm,
180 mm if the wall jig is used (ensure the
lines are horizontal). This will give the position
of the centre of the hole for the flue.
