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.
▶
Make sure that the existing gas meter is capable of
passing the rate of gas supply required.
5.1
Information on liquid gas operation
In the as-supplied condition, the product is preset for opera-
tion with the gas group indicated on the data plate.
Applicability:
Except Belgium
If you have a product that has been preset for operation with
natural gas, you must convert it to run on liquid gas. You will
need a conversion set for this. The conversion procedure
is described in the instructions supplied with the conversion
set.
5.2
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.
5.3
Using the correct gas type
Using the incorrect gas type may cause fault shutdowns in
the product. Ignition and combustion noise may occur in the
product.
▶
Only use the gas type listed on the data plate.
5.4
Integration into a solar system
The inlet temperature must not exceed 45 °C.
The hot water temperature must not exceed 60 °C.
▶
Install thermostatic 3-way valves.
5.5
Sequence for installing the connection
1.
Install the domestic hot water connection.
2.
Install the cold water connection.
3.
Install the gas connection.
5.5.1
Descaling the water
The probability of scale increases as the water temperature
increases.
▶
Descale the water as required.
5.5.2
Installing the domestic hot and cold water
connection
Warning.
Risk of adverse health effects caused by
impurities in the potable water.
Sealing residues, dirt or other residues in the
pipelines may adversely affect the quality of
the potable water.
▶
Flush all of the hot and cold water pipes
thoroughly before you install the product.
▶
Make the water connections in accordance with the relev-
ant standards.
5.5.3
Installing the gas connection
▶
Install the gas pipe in accordance with the recognised
rules of technology.
▶
Connect the product to the gas pipe in accordance with
the recognised rules of technology.
▶
Remove the residues from the gas pipe by blowing
through the gas pipe beforehand.
▶
Purge the gas pipe before start-up.
▶
Check the entire gas supply properly for leak-tightness.
