Soft Light Adjustment; Ignition Delay Adjustment; Gas Changeover - Ariston GENUS PREMIUM EVO HP 45 Design, Installation And Servicing Instructions

Checking slow ignition power
The soft light can be adjusted between the maximum power and
the minimum power.
The display shows the value between "100" and 0 of this interval.
Change the parameter if the outlet pressure from the gas valve
in the ignition phase (measured when the boiler is in hot water
heating operation) does not coincide with the values shown in the
Gas Regulation Table.
To check the slow ignition power, access parameter 2.2.0.
If needed, change the parameter value until suitable pressure is
achieved.
Heating ignition delay adjustment
This parameter – 2.3. 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.
By selecting manual, it is possible to set the delay in minutes using
the successive parameter (menu 2.3.6), 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.

Gas changeover

The boiler can be converted to use either methane (natural) gas
(G20) or L.P.G. ( G31) by an Authorised Service Centre.
The operations that must be performed are the following:
1. switch off the the electrical supply to the appliance
2. turn off the gas cock
3. disconnect the electrical connections to the boiler
4. gain access to the combustion chamber, as indicated in the
paragraph "Maintenance Guide - General Access"
5. add/remove the gas diaphragm as directed in the instruction
sheet for the Kit.
6. attach the labels contained inside the Kit
7. check that all connections are gas-tight
8. start up the boiler
9. carry out combustion analysis check CO2 parameters.
