This chapter explains how to connect the boiler on the flue gas side.

8.1 Installing a vent pipe sealing collar (accessory)

▶ Push the vent pipe as far as possible onto the draft diverter outlet.

▶ Place the vent pipe sealing collar around the vent pipe and draft

diverter outlet so that it overlaps at the top.

One of the hose clamps must press onto the draft diverter outlet and

and one onto the vent pipe.

▶ Tighten hose clamps.

The vent pipe sealing collar must fit smoothly and firmly in place after
