5.11 Refitting the case
Note:
Ensure that the front panel retaining cords are
positioned such that they will not become trap-
ped in the casing.
• Hook the top of the front casing (4) over the lip on the
top of the boiler chassis and push the bottom of the
front casing (3) into place.
• Ensure the spring retaining clips (2) engage correctly.
• Tighten case securing screw (1).

5.12 Adjusting the central heating output (range rating)
The boilers are fully modulating for central heating, and
it is therefore not necessary to range rate the boiler.
However, if desired, it is possible to range rate the boiler,
as follows:
1 Press the ”i” and ”+” buttons simultaneously.
Fig. 5.6 ff Adjusting the central heating output
2 Keep the ”+” button pressed until ”d.0” is displayed.
The display runs from ”d.0” to ”d.99” before restar-
ting at ”d.0”.
3 Press the ”i” button. The ”=” symbol is displayed. The
part–load setting is now displayed in kW.
4 Use the ”+” and ”–” buttons to increase or decrease
the value in steps of 1 kW. The displayed value will
flash while the adjustment procedure is being carried
out. The available ranges of settings are given in Tab.
