Remeha Gas 610 ECO
The Remeha Gas 610 ECO boilers are capable of oper-
\
ating with the air inlet and flue outlet in different pres-
sure zones (CLV System).
The max height difference between air inlet and flue gas
outlet is 36 meters and the maximum total length of air
inlet and flue gas outlet pipework L is shown in table 06.

Note: this system may not be used in areas with
adverse wind conditions (i.e. in some coastal regions).
Note: If the design parameters are outside the values
shown in the above table or there is any doubt over the
flue system, please contact our technical department for
calculation to be undertaken.

For multiple boiler installations with common flue sys-
tems please refer to Broag for advice.
7.4 Installation details
7.4.1 Water pressure
The individual boiler sections are each subjected to
a test pressure of 10 bar. On assembly the complete
block is subjected to a factory pressure test using com-
pressed air at 2 bar for 1 minute.
The boiler is suitable for a maximum working pressure
of 6 bar.
7.4.2 Condensate discharge
Discharge the condensate via a tundish, directly into
a drain. Only use synthetic material for the connecting
pipework because of the acidity (pH 2 - 5) and allow a
min. of 30 mm per meter fall to ensure a good flow rate.
Fill the siphons with clean water before firing the boiler
modules.
It is not advisable to discharge into an outside gutter,
because of the risk of freezing.
