The condensate discharge to the sewer must be:
 sized so as to discharge the maximum condensation flow (see Table 3.1 GS HT/LT •
technical data → 12 and Table 3.2 WS technical data → 13 under the respective 
heading);
 made of materials resistant to acidity with pH 3 to 5;•
 sized  to  ensure a  slope  of  10  mm  per  metre  of  length;  if  this  slope  cannot  be •
achieved, a condensate pump must be installed near to the discharge;
 realized in such a way as to prevent icing of the condensate;•
 mixed, for example, with domestic effluents (washing machine, dishwasher, etc.), •
usually alkaline, acting as a buffer solution before discharging into the sewer.
Do not discharge the condensate into the guttering, since it may ice and corrode the 
materials normally used for gutters.
CHARGING THE SIPHON
To charge the siphon, proceed as follows:
 Connect the condensate discharge pipe to a drain.1. 
 Remove the bottom left side panel to access the siphon.2. 
 3.  If no fumes exhaust equipment has been installed: pour 0.2 litres of water di-
rectly into the plastic pipe (detail F in Figure 5.3 Position of condensate discharge 
and manual reset fumes thermostat → 32 and check that it is full. Then proceed to 
point 6.
 4.  If the fumes exhaust equipment has already been installed: remove the clamp 
securing the plastic pipe E to the siphon (see Figure 5.3 Position of condensate 
discharge and manual reset fumes thermostat → 32), disconnect the plastic pipe E 
from the siphon and fill it with 0.2 litres of water.
