EXCLUSIVE GREEN E C.S.I. - R.S.I.
13 - START-UP AND OPERATION (EXCLUSIVE GREEN E R.S.I.)
This boiler is able to operate in different conditions:
CASE A - only heating
CASE B - only heating with external water tank connected, managed by a thermostat, to prepare domestic hot water
CASE C - only heating with external water tank connected, managed by a temperature sensor (kit available upon request), to prepare domestic
hot water.
Depending on the type of installation selected, it is necessary to set the parameter "domestic hot water mode". This operation must be performed
by a Technical Service Centre when starting-up the boiler.

The first time you turn the boiler on and in case of maintenance
work, before using the appliance you must fill the siphon with
water and make sure that the condensation is evacuated correctly.
Fill the condensation collection siphon pouring 1 litre of water into
the boiler combustion-analysis outlet with the boiler off, and check
that:
- the safety cut-off device is floating
- water is flowing correctly from the discharge pipe out of the
boiler
- the condensate outlet connection line is watertight.
If the condensate outlet circuit (siphon and pipes) is working correctly,
the condensation level will not exceed the maximum.
Filling the siphon before using the appliance, and the use of a safety
cut-off device inside the siphon, prevent exhaust gases from being
released into the environment.
Repeat during standard and non-standard maintenance work.
