Installation and Overpressure Protection
▲
Personal injury or system damage
may result if this regulator is installed,
without appropriate overpressure
protection, where service conditions
could exceed the limits given in
the Specifications section and/or
regulator nameplate.
Regulator installations should
be adequately protected from
physical damage.
All vents should be kept open to permit
free flow of gas to the atmosphere.
Protect openings against entrance of
rain, snow, insects or any other foreign
material that may plug the vent or vent
line. On outdoor installations, point the
spring case vent downward to allow
condensate to drain.
This minimizes the possibility of
freezing and of water or other foreign
materials entering the vent and
interfering with proper operation.
For the Type CS403 with the Integral
Monitor or the Type CS404 with slam
shut, point the vents of both the Primary
Regulator and Integral Monitor or slam
shut downward to allow condensate
to drain. From the factory, the Integral
Monitor or slam shut will always point
in the same direction as that of the
Primary Regulator.
Under enclosed conditions or indoors,
escaping gas may accumulate and be
an explosion hazard. In these cases,
the vent should be piped away from the
regulator to the outdoors.
