3.15 - 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”.
otherwise
the boiler will not function and can cause property damage.
The condensate must be drained from the boiler in accordan-
ce with local, state or federal rules and regulations.
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 sy-
stem must be carried out in compliance with the specific refe-
rence 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 materials which are resistant to con-
densate
- if the condensate outlet of the boiler is lower than the drain,
a condensate pump must be used.
- The condensate produced by the boiler has a pH value
between 3 and 4.
- Do not drain the condensation water to the external rain
gutter because of the danger of freezing and blockage of
the drain.
- Install a neutralization unit if required by the local code

NOTICE
Use materials approved by the authority having
jurisdiction. in the absence of such authority, PVC
and CPVC pipe must comply with ASTM D1785,
F441 or D2665. Cement and primer must com-
ply with ASTM D2564 or F493.
For Canada, use ULC certified PVC or CPVC
pipe, fittings and cement.
3.14 - UNDERFLOOR HEATING SYSTEM
(PLASTIC PIPES)
NOTICE
When using oxygen-permeable pipes, e. g. for
floor heating systems, you must separate the
system using plate heat exchangers.
No recourse can be made to the terms of the
warranty in the event of failure to observe the
regulations pertaining to plastic underfloor
heating pipes.
WARNING
Before putting the boiler into operation fill the
condensate trap with 1.27 cups / 300 ml of wa-
ter. If the boiler will be installed in a high tempe-
rature installation such as baseboard with a
supply temperature of 160°F or above, fill the
condensate trap with vegetable oil instead of
water.
Periodic cleaning of the condensate disposal sy-
stem must be carried out.
