5 Installation12 Installation and maintenance instructions ecoTEC pro 0020244995_024.9 Removing the side section2xCaution.Risk of material damage caused by mech-anical deformation.Removing both side sections may causemechanical distortion in the product, whichmay 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.5 InstallationDanger!Risk of scalding and/or risk of materialdamage 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 gasleak-tightness test.At a test pressure of >11 kPa (110 mbar), gasleak-tightness tests may cause damage tothe gas valve.▶ If, during gas leak-tightness tests, youalso place the gas lines and the gas valvein the product under pressure, use a max.test pressure of 11 kPa (110 mbar).▶ If you cannot limit the test pressure to11 kPa (110 mbar), close any gas isolatorcocks that are installed upstream from theproduct before you carry out the gas leak-tightness test.▶ If, during gas leak-tightness tests, youhave closed the gas isolator cock that isinstalled upstream of the product, relievethe gas line pressure before you open thisgas isolator cock.Caution.Risk of material damage caused by corro-sionDue to non-diffusion-tight plastic pipes in theheating installation, air gets into the heatingwater. Air in the heating water causes corro-sion in the heat generator circuit and in theproduct.▶ If you use non-diffusion-tight plastic pipesin the heating installation, ensure that noair gets into the heat generator circuit.Caution.Risk of material damage due to heat trans-fer during soldering.▶ Only solder connectors if the connectorsare not yet screwed to the service valves.Caution.Risk of material damage caused bychanges to the pipes that have alreadybeen connected.▶ Only bend connection pipes if they havenot yet been connected to the product.5.1 Installation requirements5.1.1 Information on liquefied petroleum gasoperationIn 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 tankIf the liquid gas tank is not purged properly, this may result inignition problems.▶ Ensure that the liquid gas tank has been purged properlybefore installing the product.▶ If required, contact the filler or the liquid gas supplier.
