INITIAL START-UP
b
Initial start-up must be performed by an authorised and qualified heating engineer from a
r
Technical
Assistance Centre.
Remove the front panel from the boiler and perform the following checks before switching the boiler on or testing any of
its functions.
- Check that the fuel and water shut-off cocks to the boiler are open.
- Check that the type and pressure of the gas supply are as specified for the boiler.
- Check that the central heating water pressure gauge shows a pressure between
1 and 1.2 bar
with the system cold.
Check also that the central heating circuit has been properly bled.
Once you have completed all the checks listed above,
proceed as follows to start up the boiler for the first time.
- Turn the mains power switch ON.
- Turn the boiler function selector to Summer "
}
" or
Winter "
{
" , depending on which functioning mode you
require.
b
Every time electrical power is switched on, the
boiler performs an automatic venting cycle that
lasts about 12 minutes. Throughout this cycle
the two digits of the display flash alternately.
At the end of the automatic venting cycle, check
the pressure on the gauge (7) again. If necessary,
turn the boiler off at the mains power switch and
at the control panel and refill the CH circuit as
instructed on page 28.
Once the CH circuit reaches the right pressure,
switch the boiler back on again to start the auto-
matic venting cycle.
Repeat these steps until the pressure in the CH
circuit stabilises between 1 and 1.2 bar.
b
To interrupt the automatic venting cycle, unscrew
the four screws (A), remove the front trim (B) and
press the combustion analysis button (CO).
