Installing a vent pipe sealing collar

(accessory)

We recommend you use a vent pipe sealing
collar ( Fig. 45, [1]).
B Push the vent pipe as far as possible onto the draft
diverter outlet.
B Place the vent pipe sealing collar around the vent pipe
and draft diverter outlet so that it overlaps at the top.
B Place hose clamps (Fig. 45, [4]) over the vent pipe
sealing collar. One of the hose clamps must press onto
the draft diverter outlet and and one onto the vent pipe.
B Tighten hose clamps.
The vent pipe sealing collar must fit smoothly and firmly in
place after tightening the hose clamps.
