CAUTION
Commissioning/Start up by a non-
Fulton authorized person will void the
product warranty.
Please read these instructions and
post in an appropriate place near the
equipment. Maintain in good legible
condition.
When commissioning is complete, Sola
control must be placed into automatic
mode.


NOTE: Perform the following steps for fi eld commissioning with the Dungs
Gas Valve (Figure 10).

NOTE: A combustion analyzer will be required when making changes to
the Dungs valve settings.
1. Follow the steps in the SOLA Hydronic Controller section of this manual
to access the parameters to run the boiler in manual mode.
2. Turn the boiler on and make sure that there is a call for heat. If the unit
does not go directly to pre-purge, there is not a call for heat or there is an
interlock open. If all interlocks are closed, the unit will drive to the max
RPM for pre-purge and begin countdown.
3. When pre-purge is fi nished, the unit will go to the light-off point.
4. From the test fi re sheet verify what was used for a low fi re RPM setting.
Input this setting into the Sola manual fi ring rate (Figure 14). Once the
boiler is at this RPM check combustion. Unless the combustion is way out
of the range from the test fi re sheet proceed slowly to the high fi re RPM
point. Once at high fi re take a combustion reading.

NOTE: Gas Valve adjustments will change combustion. Only minor
changes should be required due to the boiler being fully test fi red at the
factory. Gas valve adjustments should only be made at high fi re and low
fi re. If an adjustment is made at low fi re it will eff ect high fi re, and vice
versa. Always adjust high fi re before low fi re.
5. To increase the O2 level at high fi re, turn the Valve Adjustment (Gas valve
shutter on the downstream side of the gas valve, see Figure 10) slotted
screw counter-clockwise. To decrease O2 level, turn the Valve Adjustment
screw clockwise. Once the correct O2 level is reached slowly go back to
low fi re and check combustion.
6. When you have reached low fi re RPM and if O2 adjustments are required
the Valve Off set Adjustment (allen screw on the side of the valve, see
Figure 10) will need to be rotated. To increase O2 turn the Valve Off set
Adjustment screw counter-clockwise, turn in the opposite direction to
decrease O2.
7. Making changes to either adjustment on the valve will change the
combustion through the range. When any adjustments are made the
combustion should again be checked at high and low fi re.
8. Verify combustion settings are in the range specifi ed by Table 9.

NOTE: Proper set up of the Ignition Enrichment gas is crucial to the
"light-off " of the boiler and requires verifi cation in the fi eld during initial
commissioning. Fulton recommends the Ignition Enrichment setting is
verifi ed during the yearly preventative maintenance.
9. Once fi nal fi eld combustion is completed at low and high fi re, the ignition
enrichment setting requires verifi cation. Use the factory test fi re sheet to
determine the factory test fi re light-off rpm's. Input this setting into the
