7.8 Installing fittings and burner door
Next step in the assembly process is to install the burner door and draft
diverter. The pre-assembled boiler comes with these components
already installed.
7.8.1 Positioning the draft diverter
KM ropes (Fig. 28, [1]) are used to seal the connections between the
boiler and the draft diverter (Fig. 28, [2]).
▶ Coat the packing grooves with adhesive (primer).
▶ Push the KM ropes firmly into the groove. Insert the sealant rope in
such a way that the joint is in the side part of the groove (Fig. 28,
[3]).
▶ Place the draft diverter onto the two threaded studs on the rear
section (Fig. 28, [4 and 5]) and secure using washers and nuts.
