Gas supply
Proceed in the following manner:
-
make sure that the main gas supply uses the same type of gas as indicated on the boiler
data plate;
- Open all doors and windows;
- Make sure there are no sparks or naked flames in the room;
- Make sure that the system does not leak fuel using a cut-off valve inside the boiler itself
which should be closed and then opened while the gas valve is disabled. The meter must
not show any signs of gas being used for 10 minutes.
First ignition
1. Make sure that:
-
The gas valve is closed;
- The electrical connection has been properly carried out. Make sure that, in any case, the
green/yellow earthing wire is connected to an efficient earthing system;
- Use a screwdriver to lift the cap on the automatic air relief valve;
- Switch on the boiler (by pressing the ON/OFF button) and use the MODE button to select the
standby mode, where no hot water or heating requests are made.
- Start the deaeration cycle by pressing ESC for 5 seconds
The boiler will start a deaeration cycle lasting about 7 minutes. If you need to stop it press ESC.
- At the end, check that the system is completely deaerated and, if not, repeat the procedure.
- Bleed the air from the radiators;
- Check that the sys
tem’s pressure (on the display) is above 1.2 bar; if not, the display will signal
insufficient pressure and the boiler must be refilled.
- The exhaust duct for combustion products should be suitable and free from any obstructions;
- Any necessary ventilation inlets in the room should be open (type B installation).
- Check whether the siphon contains water; if not, it must be refilled. N.B.: if the boiler will not be
used for long periods, the siphon should be filled before the boiler is started up again. It is
dangerous not to refill the siphon as fumes may be released into the environment.
