In the event that twin flue pipes are used, and the boiler
has a side clearance of less than 60mm from the wall, it
is necessary to cut a larger diameter hole for the flue
pipe, this should be ø10 cm, this will then allow for easier
assembly of the air intake elbow and the tube outside the
wall (see Fig. 2.19).

In the event that the air intake and exhaust are run to the
left, it will be necessary to reduce the height of the air
intake by cutting 20mm from the base of the air intake
elbow (see Fig. 2.18)
