Commission The Boiler - FULTON Vantage VTG Series Installation And Operation Manual

SECTION 3
VTG-IOM-2016-1214
5. At this point, the system has been initially filled. However, air pockets
may still remain at high points in the system and in heating loops above
the level of the combination shut/off purge valve. It is quite possible,
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 (fill) valve set pressure. No more water should be
entering the system. Close the shutoff valve on the cold-water fill line.
9. Visually inspect all pipe joints and equipment connections for leaks. If
necessary, drain system, repair leaks and refill/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 (fill
valve), shutoff valve in cold water fill 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 flow to boiler.

Commission The Boiler

Adhere to the following when commissioning the boiler:
1. Verify with authorized personnel that the gas lines have been purged. Do
not proceed without verification.
2. Familiarize all personnel on all aspects of boiler use, safety, and contents
of this manual. This includes, but is not limited to, the use of the controls,
lighting, and shutdown procedures.
3. Review the unit-specific burner and control schematics, and follow
appropriate instructions.

WARNING
Crystalline silica may be present
in components of this equipment.
Exposure to crystalline silica may
pose significant health hazards,
including but not limited to eye and
respiratory system damage. Per
the Centers for Disease Control and
Prevention (CDC) and Occupational
Safety and Health Administration
(OSHA), appropriate Personal
Protective Equipment must be worn
to minimize exposure to hazardous
substances. Refer to most current
guidelines offered by the CDC and
OSHA for more information, including
Personal Protective Equipment
recommendations.
Do not attempt to start the boiler for
any testing before filling and purging
the boiler. A dry fire will seriously
damage the boiler and may result in
property damage or personnel injury
and is not covered by warranty.
Before commissioning the boiler,
verify with authorized personnel that
the gas lines have been purged.
Never attempt to operate a boiler
that has failed to pass all the safety
checks.
Never leave an opened manual air
vent unattended. In the event an
opened vent is left unattended, water
damage could occur.

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 qualified 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.
