9. FLUE AND TERMINAL INSTALLATION
9.1 Cutting flue to size.
!
For outset appliances with surround or spacer
Measure the total wall thickness from the outside surface of the wall to the inside face
of the surround or spacer. Deduct 35mm from this measurement to obtain the correct
length of flue unit required (See figures 12a & 12b).
!
For appliances inset in a recess
Measure the total finished wall thickness including plaster etc. Deduct 35mm from this
measurement to obtain the correct length of flue unit required (See figure 12a).
!
Mark off the flue length on the outer (air) tube measuring from the end of the
terminal.
!
Insert the polystyrene ring between the inner and outer tubes to support them. Cut
both tubes squarely at the marked distance.
Important: Remove all polystyrene from
the flue unit after cutting.
