Preparation For The Condensate Drain - Riello Condexa PRO NA 75P Installation, Operation And Service Manual

INSTALLATION

2.13.10 Preparation for the condensate drain

The exhaust of the condensation produced by the Condexa PRO
NA during its normal operation, must be carried out with an ac-
cessory (siphoned condensate collector) that needs to be installed
below the boiler as specified in its assembly instructions. The con-
densate coming out of the drain must be collected and disposed
in the sewer system, if necessary by using a neutralizer, according
to the following procedure:
− Connect the condensate hose in such a way that hose
drains into the sewer system with an air gap between the
condensate hose and the sewer system.
The connection to the local drain or sewer system must be exe-
cuted using a siphon in order to prevent unpleasant odours from
being released back into the room from the sewer.
We advise using plastic (PP) piping for building the condensate
drainage.

CAUTION: Never use copper pipes under any circumstances, as
the condensate itself will cause them to rapidly deteriorate.

WARNING: Install the condensate drain outlet so as to prevent
combustion gases leaking into the environment or the drain
or sewage system by sizing the siphon (height H) as described
in section "Combustion gas exhaust". Failure to comply may
result in substantial property damage, severe injury or death.
9
WARNING: Always maintain a slope angle "s" of over 3° and
ensure that the diameter of any condensate drain pipe is
greater than that of the connection fitted at the drain outlet
9
CAUTION: Connect the condensate drain hose to a domestic
water drain in accordance with national and local legislation
and standards.
9
WARNING: Fill the siphon with water before activating on the
boiler in order not to release any combustion products into
the environment when the boiler is first switched on. Failure
to comply may result in substantial property damage, severe
injury or death.
9
NOTE: It is recommended that condensate from the boiler and
from the flue should be channelled into the same drain pipe.
9
CAUTION: The connection pipes used must be as short and as
straight as possible. Any curves or sharp bends can lead to
hoses becoming clogged and, therefore, can prevent proper
condensate discharge
9
CAUTION: Size the condensate drain outlet so as to ensure the
proper drainage of waste liquids without leaks
9
WARNING: The condensate drain must be connected to the
drain and sewage network in such a ways so that the con-
densate may not freeze under any circumstances
