Models
“RX 26 BF”
, with a hermetically
sealed combustion chamber and air supply
circuit, may be installed in any room in the
home.
2.2
CONNECTING
UP SYSTEM
Wash all system pipes well before hooking
them up with the boiler to eliminate any
residues which could compromise its func-
tioning.
The discharge pipe of the safety
valve must be connected to a collector
funnel for channelling away any discharge
if the safety valve goes into action.
When sizing gas piping, from the meter to
the boiler, take into account both the volume
flow rates (consumption) in m
3
/h and the
relative density of the gas in question. The
sections of the piping making up the system
must be such as to guarantee a supply of
gas sufficient to cover the maximum
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).
An adhesive data plate is sticked inside the
front panel; it contains all the technical data
identifying the boiler and the type of gas for
which the boiler is arranged.
