Press Enter to confi rm this.
 Setting Modulation
Before releasing the boiler to modulation, the boiler will drive to low fi re. It is
necessary to set 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. Fine tuning of the servo setting throughout the range should
be performed only once high fi re settings are confi rmed.
Proceed as follows:
1. Under Params&Display > RatioControl > ProgramStop, change the
program stop to deactivated by using the arrow keys. Confi rm that
‘deactivated’ is acknowledged in the current fi eld.
2. 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.
3. Press Escape fi ve times to get back to the main menu.
4. Observe the status of the burner by going to OperationalStat >
NormalOperation.
5. Verify the fl ame signal on the display, measure input if fuel meter is
available. If not match last elbow pressures and combustion from test fi re
sheet. Adjust the burner as needed. To adjust the servo position, refer to
Setting Low Fire section.
 Setting Low Fire
NOTE:  As soon as a servo position is altered, the servo will move to that
position. Only change servo settings by a maximum of 0.5 degrees at a time
before verifying combustion.
Proceed as follows:
1. Go to Params&Display > RatioControl > GasSettings (or OilSettings
depending on fuel) > CurveParams.
2. Wait for the spinning line on the left to disappear. Press Enter. The number
1 should appear to the right of the cursor, this is the Point Number.
3. Press Enter once. Select ChangePoint by pressing the arrow keys to
highlight and then press Enter to select. This will cause the servo motors to
move to this low fi re point.
