2.5 Rotameter
For protection in shipment, the rotameter and associated parts are re-
moved after the gas feeder is factory tested. These parts are separately
packaged; assemble and install as indicated on Dwg. 25.055.151.010.
2.6 Vent
As shown on the typical installation drawings, a vent line is required from
the pressure relief port to a point outside the building where the gas cannot
cause injury to personnel or damage to equipment. The proper installation
of this line is important. For gases other than ammonia, the gradient of the
line must be continuous (down, if possible), without traps, and the atmo-
spheric end should point down and be screened against the entrance of
foreign materials. For ammonia, the gradient of the line must be continuous
(up, if possible), without traps, and the atmospheric end should point up
and be provided with a suitable raincap to prevent the entrance of water
and foreign materials. Allow for free discharge of vapor. Where traps are
unavoidable, provisions for condensate removal must be installed at all low
points. Suitable support for the vent is required throughout its entire length.
The vent lines from the vacuum regulator-check units are covered in a
separate book.
NOTE: See appropriate Typical Installation drawings at the end of
this section.
WARNING: THE PRESSURE RELIEF VALVE MUST BE VENTED
TO AN AREA WHERE GAS FUMES CANNOT CAUSE INJURY
TO PERSONNEL OR DAMAGE TO EQUIPMENT. DO NOT TER-
MINATE THE VENT LINE AT A LOCATION ROUTINELY USED
BY PERSONNEL, SUCH AS WORK AREAS OR PATHWAYS,
NOR NEAR WINDOWS OR VENTILATION SYSTEM INTAKES.
2.7 Electrical Connections
If the control module is furnished with built-in accessories requiring a
power supply or wiring to other equipment, appropriate wiring diagrams
will be found in the instructions for the accessory items.
NOTE: Field wiring must conform to local electrical codes.
2.8 Installation of Throat and Tailway
The throat and tailway of 3/4-inch and one-inch fixed throat injectors must
