Maximum flow temperature
NOTICE
Too much chloride in the heating water can damage the appliance.
If the chloride content in the heating water exceeds 150 ppm, the boiler
may be damaged if the heating water temperature is higher than 80 °C. If
the maximum flow temperature is set higher than 80 °C, the water
treatment must be adapted in order to reduce the chloride content.
▶ If the chloride content is more than 150 ppm, carry out a water
treatment as described in the supplied "Manual for water quality".
The boiler is supplied with a set maximum flow temperature of 80 °C as
standard. Under standard conditions, this maximum boiler temperature
is sufficient to cover the heating load and also guarantee the service life
of the boiler.
A higher maximum flow temperature may however be required for
certain installations. In these cases, the chloride content of the heating
water must be checked and reduced if necessary.
▶ With the chloride content of the heating water.
▶ If the chloride content is more than 150 ppm, perform water
treatment as described in the supplied "Manual for water quality".
▶ Set the maximum flow temperature to the required value ( § 9.4,
p. 25).

Risk of explosion
▶ Close the gas valve before working on gas-carrying components.
▶ After completing the work, check the tightness of all gas-carrying
components.

The packaging material is fully recyclable.
▶ Dispose of the boiler packaging after installing the boiler at a
recycling point.
▶ Remove the outer packaging by setting the boiler upright and pulling
it up and off.
▶ Avoid damaging the connections on the boiler at the top and bottom.
▶ Cover the flue outlet adapter of the boiler during assembly.

install the boiler in combination with the frame.
Installation on the frame (accessory)
Physical injury due to tipping of the boiler.
The frame must be securely attached to the floor or wall so that the boiler
cannot tip over.
▶ Use fixing materials that are suitable for the subsurface or wall and
offer a sufficient hold.
▶ Fasten the frame to the floor with the bracket (included).
▶ If drilling in the floor is not permitted fasten the frame to the wall.
▶ Mount the cross bars [1] to the stands [2].
▶ Secure the cross bars with the brackets [3] (included).
▶ Place the frame at the required location in the installation room.
