CAUTION
A sealed system must only be filled by a competent
person (see section Method of filling a sealed sys-
tem page 37).
6.9.1 Plumbing accessories (optional)
To facilitate plumbing and gas connections to the systems, the
accessories as shown in the table below are available and are
to be ordered separately from the boiler.
DESCRIPTION CODE
Installation plate 8075441
Connection protection kit (for
models 30-40 kW)

NOTE:
kit instructions are supplied with the accessory itself or
are to be found on the packaging.
6.10 Condensate outlet/collection
To ensure safe disposal of the condensate produced by the
flue gases, reference should be made to BS6798:2009.
The boiler incorporates a condensate trap which has a seal of
75 mm, therefore no additional trap is required.
The condensate trap can be filled prior to the installation of
the flue by carefully pouring 1 litre of water into the exhaust
connection.
NOTE: All pipework must have a continuous fall from the boil-
er and must be resistant to corrosion by condensate, copper
or steel is NOT suitable. It should be noted that the connec-
tion of a condensate pipe to a drain may be subject to local
building control requirements (Dealing with Condensate - see
Appendix 1).
6.11 Gas supply
Edea
boilers leave the factory prearranged for gas G20 and can
also work with G31 without the need for any type of mechani-
cal conversion. Simply select parameter
"03"
(see “Parameter
setting and display") page 39 and set the type of gas to be
used.
If changing the type of gas to be used, carry out the entire
appliance
"COMMISSIONING"
phase (page 39).
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 installation
date ensure the required information is recorded in the Gas
Boiler System Service Interval Record (page 51) (Benchmark).
The gas connection must be made using seamless steel or
copper 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 maxi-
mum 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.

WARNING
Once installation has been completed, check that
the joints are air tight as indicated in the installation
Standards.
m
CAUTION
It is recommended that the gas line has a suitable
filter.

CAUTION
If the gas supply is changed from G20 to G31, mark
the box on the TECHNICAL DATA PLATE.
