Removing the side section
2x
Caution.
Risk of material damage caused by mech-
anical deformation.
Removing both side sections may cause
mechanical distortion in the product, which
may cause damage to the piping, for ex-
ample, and potentially result in leaks.
▶
Always only remove one side section
–
never both side sections at the same time.
▶
Remove the side section as shown in the illustration.

Installation
Danger!
Risk of scalding and/or risk of material
damage due to incorrect installation lead-
ing to escaping water.
Stresses in supply lines can cause leaks.
▶
Install the supply lines without tension.
Caution.
Risk of material damage due to the gas
leak-tightness test.
At a test pressure of >11 kPa (110 mbar), gas
leak-tightness tests may cause damage to
the gas valve.
▶
If, during gas leak-tightness tests, you
also place the gas lines and the gas valve
in the product under pressure, use a max.
test pressure of 11 kPa (110 mbar).
▶
If you cannot limit the test pressure to
11 kPa (110 mbar), close any gas isolator
cocks that are installed upstream from the
product before you carry out the gas leak-
tightness test.
▶
If, during gas leak-tightness tests, you
have closed the gas isolator cock that is
installed upstream of the product, relieve
the gas line pressure before you open this
gas isolator cock.
Caution.
Risk of material damage caused by corro-
sion
Due to non-diffusion-tight plastic pipes in the
heating installation, air gets into the heating
water. Air in the heating water causes corro-
sion in the heat generator circuit and in the
product.
▶
If you use non-diffusion-tight plastic pipes
in the heating installation, ensure that no
air gets into the heat generator circuit.
Caution.
Risk of material damage due to heat trans-
fer during soldering.
▶
Only solder connectors if the connectors
are not yet screwed to the service valves.
Caution.
Risk of material damage caused by
changes to the pipes that have already
been connected.
▶
Only bend connection pipes if they have
not yet been connected to the product.

Installation requirements
5.1.1
Information on liquefied petroleum gas
operation
In the as-delivered condition, the product is preset for opera-
tion with the gas group indicated on the data plate.
5.1.2
Purging the liquid gas tank
If the liquid gas tank is not purged properly, this may result in
ignition problems.
▶
Ensure that the liquid gas tank has been purged properly
before installing the product.
▶
If required, contact the filler or the liquid gas supplier.
