NOTICE
Fault due to power failure!
When connecting external components to the control unit, ensure
that sum of currents consumed by these components does not
exceed the maximum current consumption of the installed control
unit.
Secure all cables with cable clips (control unit scope of delivery).
Inserting function modules
For information on the function modules, refer to the relevant technical
documentation.
Observe technical documentation of the control unit and the function
modules.
Install the hood supply air cover
After the cables have been routed, install the hood supply air cover
(Fig. 32). In doing so, insert the angled tab in the respective
recess of the front hood.
If necessary, install the cover for the combustion air with 4 screws.
7 Commissioning
This chapter describes commissioning using the standard module of the
main controller.
Before commissioning the boiler, make sure that the cover hood of
the control unit is installed.
After completing the work described below, complete the
commissioning report ( Chapter 17.6, page 72).
NOTICE
Material damage through excessive dust and dirt contamination in
open flue mode!
Heavy dust and dirt contamination can occur, for example, due to
building work at the installation location.
Install the “air filter” accessory set.
By using the “air filter” accessory set, the gas-air path and in
particular the burner rod are protected against dust.
If room sealed operation is not possible, use the air filter set which is
available as an accessory.
NOTICE
Risk of boiler damage through contaminated combustion air!
Never use chlorinated cleaning agents or halogenated hydrocarbons
(as contained in spray cans, solvents, cleaning agents, paints and
adhesives, for example).
Never store or use such substances at the installation location.
Burners contaminated during building work must be cleaned before
commissioning.
Inspect flue and combustion air pipe (with room sealed operation)
and combustion air supply and ventilation openings (
Chapter 5.6, page 19).
7.1 Checking the operating pressure
This boiler cannot be operated with open vented heating systems.
Prior to commissioning, check the operating pressure of the heating
system on the water side and adjust if required.
NOTICE
Risk of property damage due to unsuitable heating and fill water!
Unsuitable heating and fill water can cause corrosion and scale
formation and/or shorten the service life of the heating system.
Warranty claims for the heat sources will only be considered provided
the water quality requirements have been met and the operator’s log has
been maintained.
Observe the details regarding water quality in the operator's log.
If necessary, treat heating and fill water.
Provide system separation by means of heat exchangers when using
oxygen-permeable pipework (e.g. underfloor heating system).
Set the red needle [1] of the pressure gauge to the required
operating pressure of at least 1 bar.

CAUTION
Health risk through contaminated drinking water!
Observe all country-specific regulations and standards regarding the
prevention of drinking water contamination.
In Europe, observe standard EN 1717. In the UK observe the Water
Supply (water fittings) Regulations 1999.
Top up heating water or drain off water via an approved WRAS
method, until the required operating pressure has been reached.
During filling, vent the heating system via the radiator bleed valves.
