Filling The System - Sime Dewy Equipe P Box Serie Manual Del Operador

WARNING: Failure to 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.
System pipe sections must be able to gua-
rantee sufficient supply to cover maximum
demand, limiting pressure loss between the
meter and any utility device no greater than
1.0 mbar for second family gas (natural
gas).
A sticker inside the module includes identifi-
cation and gas type data specific to the
module.
2.3. 1 Condensation drain connection
A siphoned drain must be connected to the
civil drain by a pipe with minimum 5 mm
per meter gradient for condensation collec-
tion.
Only normal plastic civil drain pipes are
suitable to convey condensation to the
building's sewer drain.
2.3.2 Filter on the gas pipe
The gas valve is supplied ex factory with an
inlet filter, which, however, is not adequate
to entrap all the impurities in the gas or in
gas main pipes.
To prevent malfunctioning of the valve, or in
certain cases even to cut out the safety
device with which the valve is equipped,
install an adequate filter on the gas pipe.
