demineralised. Please also follow the manufacturer instructions.
4.4.4 Maintenance instruction
The water hardness of the heating water has to be checked within the scope of the
recommended maintenance of the boiler and, possibly, the respective amount of
additive has to be added.
4.5 Practical information for
heating contractors
1. With reference to the specific system volume (e. g. when using heating water
buffer cylinders), determine which requirements apply regarding total hard-
ness of the fill and top-up water to VDI Directive 2035 and the the following
table.
If partial softening to 6 °dH is insufficient according to the project-specific wa-
ter hardness diagram, use either an additive or use only fully desalinated water
(with pH stabiliser).
If a boiler is replaced in an existing system, we recommend installing a dirt trap
or filter in the system return, upstream of the boiler. Flush the system thor-
oughly.
2. Depending on the materials used, determine whether the addition of inhibi-
tors, partial softening or full desalination is the best method.
3. Record the filling process (use the BRÖTJE system log. If an additive is used,
note this on the boiler). To prevent gas pockets and bubbles, it is essential to
fully vent the system at maximum operating temperature.
4. After 8 to 12 weeks, check and record the pH value. Offer and conclude a main-
tenance contract.
5. Once a year, check the system is operating correctly with regard to pressure
maintenance, pH value and the volume of top-up water used.
