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 atmospheric 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. Al-
low 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 DAM-
AGE TO EQUIPMENT. DO NOT TERMINATE 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 be
assembled as shown on the parts drawings. If faulty injector action is suspected,
inspect the O-rings and replace them if there is any doubt about their condition.
2.9 Injector Suction Connection
Except in those instances where the injector is installed in the control module,
a line must be provided to carry the gas from the module to the injector. The
piping must be sized as required to obtain six inches of mercury minimum
vacuum at the module.
