22 Instructions for the installer 3.12 - MIXING HEADER FILTER UNICAL suggests the installation of a Y filter on the return pipe so that it can be cleaned if necessary. This filter will protect the boiler from the heating system dirt. 3.13 - MIXING HEADER (cod. 00361333-00361499-00361<strong>50</strong>0) In order to ensure correct boiler operation it is necessary to use a mixing header which guarantees: - the separation and collection of circuit dirt - optimal air venting - hydraulic de-coupling of the two hydraulic circulation circuits - balancing of the circuits
3.14 - CONDENSATE DRAIN During the combustion process the boiler produces condensate which, through the “A” pipe, flows into the siphon. The condensate which forms inside the boiler has to be routed into an adequate drain by means of the pipe “B”. DANGER! Before commissioning the appliance fill the siphon and check the correct drainage of the condensate. If the appliance is used with the condensate drain siphon empty there could be danger of intoxication resulting from the escape of flue gasses. The connection between the appliance and the sewage system must be carried out in compliance with the specific reference standards, and in particular: - prevent the end user utilizing the condensate produced; - a siphon must be fitted (supplied with the boiler); - there must be no bottlenecks; - the connection must be made just under the bottom part of the boiler; - it must be installed so as to avoid freezing of the liquid when the boiler is operating and prevent the eventual pressurization of the sewage system; - consent the correct downflow of the appliance’s liquid discharges; - it must be made with one of the following materials which are resistant to condensate: - Grès, according to the Standards DIN 1230-1 and 6, EN 295-1 or 2 or 3; - Glass (boron silicate); - Polyvinyl chloride (PVC) , according to DIN V 19534-1 and 2, and DIN 19538; - Polyethylene (PE) DH type, according to DIN 19535-1 and 2 and DIN 19537-1 and 2; - Polypropylene (PP) and copolymer styrene (ABS) according to DIN V 19561; - Polyesterific resin (GF-UP), according to DIN 19565-1; - Stainless steel.
