Eclipse Packaged Gas BoostPak, V2, Installation Guide 630-2, 6/22/2010
Piping Support
Use brackets or hangers to support the gas piping. If you
have questions, consult your local gas company.
Initial Fitting
• Remove any shipping materials and inspect for
foreign objects in the piping.
• Connect inlet gas piping from the utility supply to the
inlet flange as indicated by directional arrows and
system drawings.
• Connect the gas pipe requiring the boosted gas
pressure feeding your appliance to the discharge
gas pipe outlet flange, also indicated by label and
system drawing.
Vent Piping
The model MS, MR and MH BoostPaks do not require
vent piping. Vent piping may be required for components
added to the system. Check the individual product data
sheets for specific manufacturer’s recommendations.
Inlet Low Gas Manual Reset Pressure Switch
This switch may come already mounted and wired on the
BoostPak, or it may be supplied as a kit to be remotely
mounted. Install loose inlet gas low pressure switch kit in
location determined by the utility company. Normally it is
located downstream of the main regulator just inside the
building where the supply pipe enters.
Inlet High Gas Pressure Switch
If used, this optional switch may come already mounted
and wired on the BoostPak, or it may be supplied as a kit
to be remotely mounted. Install loose inlet gas high
pressure switch kit in location determined by the
specifying engineer. Normally it is located downstream of
the main regulator just inside the building where the
supply pipe enters.
Pressure Switch Settings
• Check and adjust the pressure switches as
required.
• The utility company dictates the setting of the low
inlet gas pressure switch typically at 3-4" w.c. to
prevent operation when there is insufficient gas
volume.
• The discharge gas pressure switch should be set 2-
4" w.c. below the rated discharge pressure at the
maximum flow conditions for the site application.
• If installed, the optional inlet high gas pressure
switch should be set to 90% of the pressure where
the sum of the inlet plus the rated boost equals the
maximum rating of downstream equipment.
(Alternately it can be set to 20% above the minimum
requirement of the downstream equipment.)
Leak Testing
The BoostPak is tested and leak tight at the factory,
however, shipping and installation may cause joints to
loosen. Check and test all piping for leaks.
Ŷ
Test pressure must not exceed 5 PSIG and the
pressure gauges or any components with ratings
less than the test pressure should first be isolated.
Check the individual product datasheets for
specific ratings.
Electrical Installation
General
All electrical wiring must be done in accordance with the
national electrical code, local utility company and
municipal agency requirements. The schematics are
shipped with the BoostPak. Contact Eclipse for
replacement, drawing 10025020.
The BoostPak is pre-wired and therefore only the
electrical power supply and any externally supplied
control devices must be terminated. Depending on the
specific model configuration, the external devices can
include the appliance run interlock contact and the low
inlet gas pressure switch.
Review Name Plate
Before making any electrical connections, compare the
electrical supply circuit ratings at the installation site to
those on the nameplates of the BoostPak, control panel,
booster and (MH only) heat exchanger motor(s). The
supply for the BoostPak model MS/MR/MH varies based
on booster and motor option, and may be 120VAC,
208VAC, 230VAC or 460VAC nominal and must be
capable of supplying the booster and (MH only) heat
exchanger motor full load current and starting current.
Terminal Check
During shipment, the control panel terminals may have
loosened. Check the tightness of all connections in the
panel and at the pressure switches.
Supply Power Wiring
The incoming power to the control panel must be wired
into the terminals as designated in the schematic diagram.
Earth ground must be connected to terminal G.
Wiring for Continuous Operation
This control mode allows an operator to turn a local
control panel switch on when pressure boost is needed
and turn the switch off when the boost is not needed. For
this mode, a jumper is installed between terminals 1321
and 2161.
