3.10 - 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 pres-
surization of the sewage system;
- consent the correct downflow of the appliance’s liquid di-
scharges;
- 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) accor-
ding to DIN V 19561;
- Polyesterific resin (GF-UP), according to DIN 19565-1;
- Stainless steel.
