10.3 REAR Flue
If a wall thickness is between 203mm min. to 413mm max.
then the ue can be used without extensions.
With the ue elbow temporarily tted, measure the distance
from the outside wall to the butt joint, see diagram 10.4. If
the measurement ‘Y’ exceeds 525mm, then the appropriate
length of extension pipe is required.
If the dimension is less than 315mm DO NOT cut the ue, it
can project to a maximum of 600mm, refer to diagram 10.5. If
this is not desirable then a Standard ue MUST be used and
cut to length.
