9 - START UP PROCEDURE
NOTICE
First ignitions immediately after installation, system will
implement a self-learning procedure to reach correct
ignition level.
9.7 Commissioning For The First Time:
1.
Turn power to boiler on. Code
"000"
appears on the
display. Appliance is ready for "commissioning" procedure.
2.
Press
at the same time. Hold for 6 seconds. "

" function is active. This
function lasts 10 minutes.
3.
Boiler will turn on after deaeration function is complete.
Display will show code "
000
" alternating with
%
of
ignition power and temperature value (°F / °C).
• During this
gas recognition function
phase which
lasts about 7 minutes, type of gas being used is
analyzed.
• During this function, ensure maximum heat exchange
out to the system with all zones and circulators running.
Maintain system temperature below 176° F for duration
of the process until
NG
or
LPG
are seen on the display.
• If boiler operates on Gas A (Natural Gas) and display
shows
LPG
(Gas E), press
and
together
and hold down for at least 4 seconds to exit without
changing factory setting. Boiler will stay set to Natural
Gas.
• If boiler operates on Gas A (Natural Gas), display shows
NG
(Natural Gas) for about 10 seconds. Boiler is now
ready for normal operation.
• If boiler operates with Gas A (Natural Gas), and the
display shows LPG (Gas E) press
and
together
and hold down for at least 4 seconds to exit the
function. Change parameter
P02=01
as described in
section 9.15 Parameter
Settings
of boiler Installation,
Operation and Maintenance Manual. Perform Automatic
Calibration Function. Manual Calibration may be
necessary if combustion is not within specified range.
• If boiler operates on Gas E (LPG) and display shows LPG,
press
for at least 6 seconds to confirm gas used.
•
After fuel type is detected confirm
P02
is set for the
desired fuel type by checking parameter see section 9.15.
NOTICE
All connections shall be made and water added before
performing this function.
9.6 Prior to Commissioning:
• Check system pressure is correct;
• Power boiler;
• Open gas tap (positioned under boiler);
• Select required heating mode. See section 10.4
Operating Modes.
Note
Boiler must not shutoff during calibration.
Open all heating zones in heating or DHW
mode to ensure boiler does not shutoff.
9.8 Automatic Calibration Function
Before performing this function verify there are no heat
demands in progress.
During this function ensure there is maximum heat exchange
to the system in Heating or DHW mode (DHW request) to
avoid boiler shutting off due to overheating.
Press
and
together and hold for about 6 seconds.
When display indicates "
On
" press
within 3 seconds after
pressing previous buttons.
NOTICE
IMPORTANT:
If Calibration function does not
complete, verify unit did not shut down for over-
temperature. Repeat Automatic Calibration. Replace
KEY if Automatic calibration does not complete after
second try.
NOTICE
Important:
If display indicates "
303
" Automatic
Calibration function has not been activated. Disconnect
boiler from main power supply for few seconds and
repeat procedure.
1.
When function is enabled, and
will flash on the
display.
2.
After ignition sequence, which can also take place
after few attempts, boiler performs three operations.
Each operation lasts about 1 minute:
• maximum power
• ignition power
• minimum power
3.
Before moving to the next combustion point the and
appear on the display as the control is setting values.
4.
During this phase, power level reached by boiler and
delivery temperature alternate on the display.
5.
When , and
flash together on the display,
automatic calibration function has completed.
6.
Press
to exit the function. Display will show
ESC
.
7.
Verify combustion is within specified range. If not,
perform Automatic and then Manual Calibration. (See
Section 9.8 and 9.9)
WARNING
Asphyxiation hazard! Fill condensate trap before
starting boiler to avoid combustion products escaping
boiler. Failure to follow these instructions could result
in death or serious injury.
