7.2 Flue System (cont.)
16. Pass the air duct collar and air cowl over the 60mm
flue duct (Fig. 28) and secure the collar to the closure
plate with the screws supplied (Fig. 29). The air cowl
will fit snugly over the collar.
17. Cut the protruding 60mm flue duct down so that 5
ribs are visible and fit the remaining 60mm lip seal into
the first groove (Fig. 30). The flue duct adaptor can
now be fitted in the same manner as the boiler adaptor
(Fig. 31).
18. Fit the terminal cap over the flue duct adaptor and
air cowl. Once the cap is clipped into position it cannot
be removed easily without damage (Fig. 33).
19. Cement over the closure plate and air duct collar to
a depth of approximately 100mm. Consideration should
be given to the potential accumulation of snow in this
area, and the possibility of it blocking the air inlet
(Fig. 34).
