The boiler must be installed in a fixed loca-
tion and only by specialized and qualified
firms in compliance with all instructions
contained in this manual. Furthermore, the
installation must be in accordance with cur-
rent standards and regulations.
2.1 BOILER ROOM
The “DEWY” version boilers can be instal-
led in any domestic environment without
any location restrictions or comburent air
requirements.
2.2 CONNECTING UP SYSTEM
To protect the heat system from damaging
corrosion, incrustation or deposits, after
installation it is extremely impor tant to
clean the system using suitable products
such as, for example, Sentinel X300 or
X400. Complete instructions are provided
with the products but, for further informa-
tion, you may directly contact GE Betz.
For long-term protection agains corrosion
and deposits, the use of inhibitors such as
Sentinel X100 is recommended after clea-
ning the system. It is important to check
the concentration of the inhibitor af ter
each system modification and during main-
t enance f ollowing t he manuf actur er’s
instructions (specific tests are available at
your dealer). The safety valve drain must be
connected to a collection funnel to collect
any discharge during interventions.
WARNING: Failur e t o clean the heat
system or add an adequate inhibitor inva-
lidates the device’s warranty.
Gas connections must be made in accor-
dance with current standards and regula-
tions. When dimensioning gas pipes from
the meter to the module, both capacity
volume (consumption) in m 3 /h and gas
density must be taken into account.
The sections of the piping making up the
system must be such as to guarantee a
supply of gas sufficient to cover the maxi-
mum demand, limiting pressure loss
between the gas meter and any apparatus
being used to not greater than:
–1.0 mbar for family II gases (natural gas);
–2.0 mbar for family III gases (butane or
propane).
A sticker inside the module includes identifi-
cation and gas type data specific to the
module.
