Maximun Heating Power adjustment
The maximum heating power can be adjusted to between the maxi-
mum power allowed by the boiler and the minimum power).
To check the maximum heating power, access menu 2/sub menu 3/
parameter 1, check the value and, if necessary, modify it as indicated
in the Gas Regulation table.
Checking slow ignition power
The soft light can be adjusted between the maximum power (shown
on the display as “99”, i.e. 100%) and the minimum power (shown on
the display as “1”, i.e. 1%).
To check the slow ignition power, access menu 2/sub menu 2/
parameter 0.
If needed, change the parameter value until suitable pressure is
achieved
Heating ignition delay adjustment
This parameter – menu 2/sub menu 3/parameter 5 - can be used
to manually (0) or automatically (1) set the delay time before the
subsequent reignition of the burner after it has switched off on
reaching the desired temperature in central heating mode.
By selecting manual, it is possible to set the delay in minutes using the
successive parameter (menu 2/sub menu 3/parameter 6), to a time
between 0 and 7 minutes.
Automatic selection means that the boiler will establish the delay
time based on the set-point temperature

)
To set/modify the absolute heating power, access the gas valve and
proceed as follows:
1. Insert the pressure gauge connection tube into the pressure
connection point.
2. Disconnect the air chamber compensation pipe.
3. Run the boiler at its maximum heating power. Activate the “cleaning”
function (press the RESET button for 5 seconds, the display will show
t --), and press the “+” button; t
--
will appear on the display.
The supply pressure must correspond with that recommended
in the "gas settings" table for the type of gas for which
the boiler was designed. To check the boiler's absolute
heating power, access menu 2/sub-menu 3/parameter 0.
4. Reconnect the compensation tube.
5. The cleaning function is automatically deactivated after 5
minutes.
Changing the gas supply
These machines are designed to work using natural gas or propane
gas. The gas must be changed by a qualified professional.
The conversion operations are as follows:
1. turn the boiler's power supply off by pressing the ON/OFF
button,
2. switch the external bipolar switch to OFF,
3. close the gas tap,
4. access the combustion chamber, as indicated in the section
entitled “Instructions for removing the housing and inspecting
the appliance”
5. replace the injectors and stick the label as indicated in the
conversion kit instructions,
6. check for gas leaks
7. start up the appliance
8. check the gas setting as indicated in the section entitled “Gas
settings”:
- check the setting at the maximum domestic hot water power,
- check the setting at minimum power,
- check the setting of the absolute heating power
- check the setting of the maximum heating power
- check the setting of the slow ignition
- check the setting for the heating ignition delay
9. carry out the combustion analysis.
