WARNING
All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct,
and strict adherence to applicable
jurisdictional/professional codes and
regulations.
Ð
CAUTION
Do not use this equipment if any part
has been under water (or subjected to
heavy rains/water if the equipment
does not have NEMA 4 wiring, controls
and instrumentation). Immediately
call a qualifi ed service technician to
inspect the equipment and to replace
any part of the control system and/or
gas control(s) which have been under
water.
Please read these instructions and
post in an appropriate place near the
equipment. Maintain in good legible
condition.
depending on the particular system that all piping above the combination
shutoff /purge valve still contains air. If manual vents are installed on the
system high points, these should be opened to vent these locations. When
only water is discharged from all vents, the initial purging is complete.
6. Open the combination shutoff / purge valve (keep the vent closed). With
the gas shutoff valve closed, turn on power to the boiler and operate the
circulator. Circulate the system water for approximately 30 minutes to
move all air to the automatic air separation point.
7. Again, open manual air vents at high points of heating loop until a
constant stream of water is discharged from the vent. Close the vent and
make sure it’s watertight. Repeat procedure for all high points and for
every zone.
8. Check temperature/pressure indicator reading, which should equal the
pressure-reducing (fi ll) valve set pressure. No more water should be
entering the system. Close the shutoff valve on the cold-water fi ll line.
9. Visually inspect all pipe joints and equipment connections for leaks. If
necessary, drain system, repair leaks and refi ll/purge the system. If no
pressure drop is detected for a period of two hours under pressure, the
system may be considered watertight.
10. When purging is completed, make sure the following are open—
combination shut-off /purge valve, shutoff valve to pressure reducing (fi ll
valve), shutoff valve in cold water fi ll line, and shutoff valve in return line.
11. Make sure the following are closed - all drain cocks, the vent on the
combination shutoff -purge valve, & all manual vents. Reset zone valves to
normal mode of operation and turn off power to boiler.
12. Open fuel shutoff valve, allowing fuel to fl ow to the boiler.
Start-Up Service
If start-up service has been included in the order, the factory should be contacted
after the installation has been successfully completed and approved by the
client’s representative or engineers. Where possible, contact the factory at least
three weeks before a Fulton service engineer is required on site.
Consider the following in preparation for your on-site visit:
1. All procedures covered in manual sections Start-Up Preparation and
Fill the System, including installation review, air testing of piping, pump
alignment (where applicable), and fi lling the system must be completed
before the service person’s arrival.
2. Depending on the size of the system and the amount of service time
contracted, start-up service includes fi ring the boiler, checking, verifying
and adjusting all safety settings.
3. Careful preparation can expedite the commissioning of your boiler. Most
delays can be avoided by following the instructions in this manual. Failure
to complete required procedures properly can result in the need for further
