Installation
!
WARNING
Personal injury, equipment damage or
leakage due to escaping gas or bursting of
pressure-containing parts might result if these
regulators are overpressured or installed
where service conditions could exceed the
limits for which the regulators were designed,
or where conditions exceed any ratings of
the adjacent piping or piping connections.
To avoid such injury or damage, provide
pressure-relieving or pressure-limiting
devices (as required by the appropriate code,
regulation or standard) to prevent service
conditions from exceeding those limits.
Additionally, physical damage to a regulator
could cause personal injury and property
damage due to escaping gas. To avoid such
injury and damage, install the regulator in a
safe location.
A regulator may vent some gas to the
atmosphere in hazardous or flammable gas
service, vented gas might accumulate and
cause personal injury, death or property
damage due to fire or explosion. Vent a
regulator in hazardous gas service to a
remote, safe location away from air intakes or
any hazardous location. The vent line must be
protected against condensation or clogging.
Before installing the regulator, check for damage which might
have occurred in shipment. Also check for dirt or foreign
matter which may have accumulated in the regulator body
or in the pipeline. Apply pipe compound to the male threads
of the pipeline and install the regulator so that the flow is in
the direction of the arrow cast on the side of the body. The
diaphragm actuator assembly can be rotated to any position
relative to the body, in 90° increments. Remove the two
cap screws that hold the body to the actuator in order to
rotate the diaphragm actuator assembly.
Do not install the regulator in a location where there can be
excessive water accumulation, such as directly beneath a
downspout or in an undrained pit.
To obtain the maximum flow capacities or other performance
characteristics, the length of pipe from the regulator outlet
to the meter should have no bends and should be the same
size as the regulator outlet. Replace the regulator if water
gets into the spring case or the lower casing of the regulator.
CAUTION
You are advised to use new vent piping
because defective threads on the relief
vent piping may interfere with the venting
assembly if the piping obstructs the
movement of the vent flapper.
On indoor installations, the vent should be piped outside
the building. Remove the screen from the regulator vent
connection and connect vent piping from that connection
to the outdoors. Install a weather and insect resistant
vent assembly on the outside end of the pipe. Inspect the
vent opening regularly. On some installations, it may be
necessary to install the regulator beneath a protective hood.
The vent should be pointing or sloping down sufficiently
to allow any condensate to drain. Also check the regulator
periodically for external or internal corrosion.
Overpressure Protection
!
WARNING
Some type of overpressure protection is
needed if actual inlet pressure can exceed
the outlet pressure rating. Overpressuring
any portion of this equipment may cause
1. The pressure/temperature limits in this installation sheet and any applicable standard or
code limitation should not be exceeded.

damage to regulator parts, leaks in the
regulator or personal injury due to bursting
of pressure-containing parts or explosion
of accumulated gas.
Type HSR regulators provide internal relief that limits the
total outlet pressure buildup over setpoint. This internal relief
may be adequate for the application, if not, provide additional
pressure relief or a pressure-limiting device downstream.
Regulators should be inspected for damage after any
overpressure condition.
!
WARNING
To avoid personal injury or property damage
due to explosion or damage to regulator or
downstream components during startup,
release downstream pressure to prevent an
overpressure condition on the diaphragm of
the regulator.
In order to avoid an overpressure condition
and possible equipment damage, pressure
gauges should always be used to monitor
pressures during startup.
Startup
With proper installation completed, slowly open the
shutoff valve. Check all connections for leaks. Check the
downstream equipment for proper operations.
Adjustment
To increase the outlet pressure setting, turn the adjusting
screw clockwise. To reduce the outlet pressure setting, turn
the adjusting screw counterclockwise. A pressure gauge
should always be used to monitor downstream pressure
while adjustments are being made. Do not adjust the
spring to produce an outlet pressure setting above the limit
identified on the information label. If the required pressure
setting is not within the range of the spring being used,
substitute with the correct spring. When changing the spring,
also change the range identified on the information label
to indicate the actual pressure range of the spring in use.
After the spring adjustment has been completed, replace the
closing cap.
