Eclipse Packaged Gas BoostPak, V2, Installation Guide 630-2, 6/22/2010
Commissioning
Introduction
In this chapter you will find information and procedures for
the first operation and adjustment of the BoostPak.
Ŷ
Only qualified personnel, with good mechanical
and electrical aptitude should adjust, maintain, or
troubleshoot any mechanical or electrical part of
this system. They should have knowledge and
experience with combustion equipment including
piping, valves, motors, blowers, boosters,
switches, control panels and wiring.
These instructions rely on the expertise of the person
performing the start up. If you do not understand any
portion of this procedure or do not feel qualified, stop and
call Eclipse.
Applying Power
Before applying the site electrical power supply to the
BoostPak control panel:
• Turn off the main disconnect switch.
• Turn the HAND/OFF/AUTO control switch to OFF.
Motor Rotation Check
Ensure that the booster gas supply is off and the booster
has no gas under pressure in it. Remove the pipe plug in
the observation port on the booster body. Turn the control
panel main disconnect switch on and verify that the panel
instrumentation has power. Momentarily turn the MAN/
OFF/AUTO switch to MAN position to “bump” the motor
starter such that the motor just starts to turn and rotates
slowly. Observe the direction of rotation of the fan blades
through the observation port. They should be turning in
the direction indicated by the rotation arrow on the
booster. If rotation direction is incorrect, have a qualified
electrician rewire the incoming power for the proper
direction.
Applying Gas Supply
Before applying the site gas supply, reinstall the pipe plug
and initially set the manual butterfly valves:
• Open the booster inlet valve
• Close the booster outlet valve
• Close the heat exchanger isolation valves (MH only)
Turn on the gas supply to the BoostPak and press the
reset on the Inlet Low Gas Manual Reset Pressure
Switch.
Operational Tests
Test the operation of the BoostPak and verify:
•
DISCHARGE PRESSURE SWITCH:
The low gas
light and alarm comes on with the outlet valve
closed. The booster should remain running.
•
LOW INLET GAS PRESSURE SWITCH:
The
booster stops, the low gas light and alarm comes on
when the Inlet Low Gas Manual Reset Pressure
Switch is adjusted above the inlet gas supply. Adjust
this switch back to the original specified set point
and observe that the system will not restart unless
the pressure switch is first manually reset.
•
APPLIANCE RUN INTERLOCK:
For appliance on
demand operation mode, turn the control switch to
AUTO and test that the system runs when the
appliance interlock makes contact.
Verify Settings
1.
Run system at nominal flow rating.
2.
Verify pressure increase from booster is correct. Read
the inlet and outlet pressure gauges on the BoostPak.
Subtract the inlet from outlet pressure to verify added
pressure agrees with the datasheet.
3.
Verify that outlet pressure is sufficient for appliance
operation.
4.
Verify flow is sufficient for appliance via gas metering
located at the appliance (not included with BoostPak).
5.
Run system to minimum flow condition; verify flows
and pressures within acceptable range. For model
MR or MH BoostPak, verify that recirculation flow is
sufficient to keep outlet pipe surface temperature
below 160°F.
6.
Record all setup data as an aid for future
troubleshooting and setup operations.
