5.10 Condensate outlet/collection
In order to collect the condensate, it is recommended that:
– the appliance condensate outlets and the smoke outlet are
ducted
– a neutralising device is prearranged
– the outlet incline is
>3%
.
m
CAUTION
– The condensate outlet duct must be airtight, suita-
bly sized to that of the siphon and must not be re-
stricted at any point.
– The condensate outlet must be constructed in full
compliance of the National or Local regulations in
force.
– Before commissioning the appliance, fill the siphon
with water.
5.11 Gas supply
Murelle Revolution 30
boilers leave the factory prearranged for
gas G20 (methane) and can also work with G31 (propane) with-
out the need for any type of mechanical conversion.Simply se-
lect parameter
"03"
(see “Parameter setting and display" page
60) and set the type of gas to be used.
If changing the type of gas to be used, carry out the entire ap-
pliance
"COMMISSIONING"
phase (page 50).
As a condition of the warranty and to ensure correct operation
and efficiency, it is important that the boiler is serviced every
12 months, within 30 days of the anniversary of the installa-
tion date ensure the required information is recorded in the Gas
Boiler System Service Interval Record (page 75) (Benchmark).
The gas connection must be made using seamless steel or cop-
per tube.
Where the piping has to pass through walls, a suitable insulat-
ing sleeve must be provided.
When sizing gas piping, from the meter to the boiler, take into
account both the volume flow rates (consumption) in m3/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
output available from the boiler, 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).
An adhesive data badge is sited inside the front panel; it con-
tains all the technical data identifying the boiler and the type of
gas for which the boiler is arranged.
m
CAUTION
If the gas supply is changed from G20 to G31, mark
the box on the TECHNICAL DATA PLATE.
