2.3.5 Fitting the control, routing probes and sensors
1. Remove the transport locking device (1, Detail A) from
the heating surface motor by releasing the nut (1a)
and remove screw with locking nut (1b).
Reattach
the heating surface motor by replacing the M8 nut
and locking ring.
2.
Fit the automatic firing device:
-
Insert the four M5x50 screws (2, Figure 14) into the
support plate (2a) from below.
- Place the support plate on the bracket on the boiler
(2b, Detail A
) and fix it in position with two M6x12
screws (2c) each on the left and right.
- Turn the four M5x12 screws (Detail B) half-way into
the support plate.
Pos. 2d, type BioLyt (8-13)
Pos. 2e, type BioLyt (15-36)
Then hook the automatic firing device (2f, Figure 14)
onto the previously fitted screws (2d, 2e) and fix it
in position.
3. Route all cables from the burner, bottom section
and heat exchanger to the automatic firing device
(cable routing as shown in Figure 14).
When routing the cables, ensure that the
cables do not touch any hot or sharp-
edged components and that they are not
damaged in any way.

4.
After all the cables have been routed, proceed to fit
and secure the plug-in connections according to the
diagram on the automatic firing device.
5. Fit the side walls:
- Remove screw (5, Detail C) on the bottom section
(attachment bracket is pre-fitted on the left side wall).
- Working from above, hook the left side wall (5a) into
the support plate (2a) and into the bolts on the floor
of the boiler. Then secure by replacing the screw (5)
which was removed before.
- Working from above, hook the right side wall (5b)
into the support plate (2a) and into the bolts on the
floor of the boiler.
6.
Fit the cables on the edge of the automatic firing
device (2f) and attach with a cable tie (Detail D).
7. Mount the controller box:
-
Remove the shoulder screw (7, Figure 14).
-
Establish the plug-in connections between the
control (7a) and the automatic firing device (2f)
(bus connection RS485, connector XU).
-
Route the return sensor (RLF/VE1) from the bottom
section to the control and plug it in.
-
Hook the controller box (7a) into the side walls
(5a, 5b) and fit the shoulder screw again.
-
Connect the safety temperature limiter (STB) (7b)
by attaching flat connector at mounting tongues 1
and 2. Position and attach the capillary sensor (7c)
in the immersion sleeve on the bottom section.
8. Fit the protection plate (8, Detail A) with one screw
(8a, M5x12) each on the left and right.
