combustion. Adjust the burner to match the test fi re sheet for main burner
ignition. The procedure described in Setting Main Burner Ignition is used.

check the burner throughout its modulation range. Press Escape twice to
get back to the main menu.
 SETTING MAIN RUN MODULATION
1. Upon releasing the heater to main run modulation, the heater will drive to
low fi re.
2. It is necessary to set/check combustion through the entire range of
modulation fi rst to enable high fi re to be reached. Once high fi re is
achieved, the incoming gas pressure can be set (if required). Fine-tuning
of the servo setting throughout the range should be performed only once
high fi re settings are confi rmed.
3. Note: If the burner loses fl ame while driving to a point then:
» Turn the main ON/OFF switch to OFF.
» Reset the loss of fl ame fault.
» Press Escape on the AZL once.
» Press Enter on the AZL to reset the control. The red light on the
panel box door should go out. Adjust the air and gas servos for
that point while the burner is off .
» Follow steps below.
» Turn the main ON/OFF switch to ON.
4. Under Params&Display >RatioControl >GasSettings >ProgramStop,
change the program stop to deactivated by using the arrow keys. Confi rm
that ‘deactivated’ is acknowledged in the current fi eld.
5. This change will allow the burner to modulate. The burner will now drive
to low fi re. Remember, it is only important at this stage to set low fi re to be
stable and with clean combustion. Exact setting is to be performed once
high fi re is confi rmed.
6. Press Escape 5 times to get back to the main menu.
7. You can observe the status of the burner By going to OperationalStat/
NormalOperation.
8. Verify the fl ame signal on the display, measure input if gas meter is
available. If not, match last elbow pressures and combustion for test fi re
sheet. Adjust the burner as needed.
