12.1 COMMISSIONING
When lighting the boiler for the first time perform the following procedure. After electrically powering the boiler the code
"
000
" appears on the display. This means the appliance is ready for the "commissioning" procedure.
•
Press
together and hold down for 6 seconds. "
On
" appears on the display for 2 seconds followed by code "
312
"
indicating that the "
de-aeration
" function is active. This function lasts 10 minutes.
•
Afterwards, the boiler switches on, the display shows the code "
000
" alternating with the
%
of ignition power and the temperature
value (°F / °C). During this "
gas recognition function
" phase, that lasts approximately 7 minutes, the type of gas used is
analyzed. During this function, assure maximum heat exchange to the heating or DHW system (domestic hot water demand)
by having all heating zones open or all domestic hot water taps open, in order to prevent the boiler from switching off due to
overheating.
•
If the boiler runs on Gas A (Natural Gas), the display shows
NG
for approximately 10 seconds. The boiler is now ready for
normal operation. If the display shows
LPG
(Gas E), press
and together and hold down for at least 4 seconds to exit
without changing the factory setting. The boiler will stay set to natural gas.
•
If the boiler runs on Gas E (LPG) the display shows
LPG
(Gas E). Press
for at least 6 seconds to confirm the gas effectively
used. If the display shows
NG
(Gas A) and does not recognize the type of gas used, press
and together and hold
down for at least 4 seconds to exit the function and then change parameter
P02=01
as described in section 14: “PARAMETER
SETTINGS” of the boiler instructions manual.
IMPORTANT INFORMATION
If the venting or gas recognition function is interrupted by a power blackout, start the function again when power is
restored by pressing
and
together and holding them down for at least 6 seconds. If the display shows fault E118
(low pressure in hydraulic circuit) during the venting function, open the filling tap on the appliance and restore the
correct pressure. If the gas recognition function is interrupted due to a fault (e.g.: E133 no gas) press
to reset and
then press
and
(for at least 6 seconds) to restart the function again. If the gas recognition function is interrupted
due to overheating, restart the function by pressing
and
and holding them down for at least 6 seconds.
The combustion of this appliance has been factory controlled, calibrated and set for operation with Gas A (Natural
Gas).
During the Gas Type Control Function, the combustion ratio will increase for a short period of time while the gas type
is being established.
NOTICE
During initial ignition, the burner may not ignite (causing the boiler to shut down) until any air in the gas pipes is
vented. In this case, repeat the ignition procedure until gas reaches the burner. To reset boiler operation, press
for
at least 2 seconds.
NOTICE
For the first few ignitions immediately after installation the system must implement a self-learning procedure to reach
the correct ignition level.
