9 - START UP PROCEDURE
NOTICE
During initial ignition, burner may not ignite. This may
cause boiler to shut down until any air in gas pipes is
vented. Repeat ignition procedure until gas reaches the
burner. To reset boiler operation, press
for at least
2 seconds.
NOTICE
First ignitions immediately after installation, system will
implement a self-learning procedure to reach correct
ignition level.
9.6 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. "On"
appears on the display for 2 seconds followed by code
"312" indicating "de-aeration" 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
the duration of the process until NG or LPG are seen
on the display.
• 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 on Gas E (LPG) display shows LPG
(Gas E). Press
for at least 6 seconds to conrm gas
used.
• If 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 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. Change parameter P02=01 as described in
section 9.12 Parameter
Settings
of boiler Installation,
Operation and Maintenance Manual. Perform Automatic
Calibration Function. Manual Calibration may be
necessary if combustion is not within specied range.
• After furel type is detected, conrm P02 is set for
the desired fuel type by checking the parameter in
following section 9.12.
NOTICE
All connections shall be made and water added before
performing this function.
9.5 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 shuto during calibration.
Open all heating zones in heating or DHW
mode to ensure boiler does not shuto.
9.7 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 o 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 ash on the
display.
2.
After ignition sequence, which can also take place
after few attempts, boiler performs three operations.
Each operation lasts about 2 minutes:
• 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 ash together on the display,
automatic calibration function has completed.
6.
Press to exit the function. Display will show ESC.
7.
Verify combustion is within specied range. If not,
perform Automatic and then Manual Calibration. (See
Section 9.8)
