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.

7.8.4 Fitting burner door panel
In the factory, the burner door is mounted with the hinges on the right
hand side (Fig. 31, [4 and 6]). For left-hand closing, remove the hinges
accordingly on the left-hand side of the burner door.
▶ Screw the hinge pins (Fig. 31. [1 and 3]) to the front boiler section
with 2 M 12 x 50 machine screws in each case. This is shown in
Fig. 31 for the right-hand closing version. For left-hand closing,
secure hinge pins accordingly on the left-hand side.
▶ Affix Ø 18 mm diameter GP cord in the front section using adhesive.
The sealant rope joint should be located at the side (Fig. 31, [2]).
▶ Hook the burner door with the hinge lobes into the hinge pins.
In pre-assembled boilers, the flue gas baffles are already
fitted
▶ Remove the cardboard transport protectors from the
pre-assembled boiler.
