1. This applies to outlet pressure settings below 25 psig only.
For pressure setting above 25 psig, outlet pressure is limited to
45 psig the maximum emergency outlet pressure.
2. This applies to outlet pressure settings below 350 psig only.
For pressure settings above 350 psig, outlet pressure is limited to
550 psig, the maximum emergency outlet pressure.
3. Internal parts of the regulator may be damaged if the outlet
pressure exceeds the pressure setting beyond the amounts shown.

CAUTION Over-pressuring the 5600 regulator or the 5600R relief
valve may result in valve damage or personal injury due to failure
of pressure containing parts. Avoid over pressuring by providing
over-pressure protection devices to prevent exceeding the operating
pressure limits stated in the specifications of this product.

1. The sum of the outlet pressure setting and the maximum
allowable pressure drop determines the maximum allowable inlet
pressure for a given installation. For example, with a 1/2 port
diameter (maximum pressure drop of 250 psi) and a 400 psig outlet
pressure setting, the maximum inlet pressure is 650 psig (250 psi
plus 400 psig).

2.0 INSTALLATION & SERVICE
2.1 Installation and Start-Up
1. Remove the shipping plugs from both the regulator inlet and
outlet connections. 2. Make certain that the inside of the piping
and the regulator inlet and outlet are clean they must
be free of dirt, pipe dope, and other debris. 3. Use pipe joint
material only on the male threads of the pipe being connected to
the regulator. Do
not use pipe joint material on the female threads of the
regulator. 4. Install the regulator in the line. The regulator may
be installed in any position: right side up, up
side down, vertical piping, diagonal piping, etc. The diaphragm
case vent must be positioned to protect against flooding, drain
water, ice formation, traffic, tampering, etc. The vent must be
protected against nest-building insects to prevent vent blockage
and to minimize the chances of foreign material collecting in the
vent side of the regulator diaphragm.
5. Turn gas on very slowly.
CAUTION If an outlet block valve is used, it should be opened
first. Do not overload the diaphragm with a sudden surge of inlet
pressure. Monitor the outlet pressure during start-up to prevent an
outlet pressure overload.
6. Make certain that there are no leaks and that all connections
are tight. 7. Adjust setpoint (outlet pressure) by turning
adjustment screw. Turn clockwise to increase and
counterclockwise to decrease. Be sure to tighten lock nut after
adjustment is completed. Do not adjust when regulator is closed (no
flow). Only adjust when gas is flowing through regulator.
8. The spring case housing vent connection is a potential escape
path (in the event of a diaphragm rupture) for flammable gas. The
Model 5600 / 5600R regulator must be located and/or piped so that
potential discharge occurs in a safe area away from buildings, open
flames, collection areas, arcing devices, etc. Regulators that are
installed indoors or in a non-vented area must be vented to the
outside. Simply run vent piping (minimum 1/4NPT) from the regulator
vent connection to a non-hazardous location on the outside away
from any potential sources of ignition. The outlet of the vent
piping must allow for the free and unobstructed passage of air and
gas.
9. For applications involving combustible gas with a specific
gravity greater than 1.0 it is recommended that the gas be vented
outdoors where the gas will not collect in low areas and away from
possible ignition sources.
CAUTION Regulators are pressure control devices with numerous
moving parts subject to wear. Regulator wear is dependent upon
particular operating conditions. To assure continuous satisfactory
operation, a periodic inspection schedule must be adhered to with
the frequency of inspection determined by the severity of the
service and applicable laws and regulations.

2.2 Diaphragm Replacement 1. Relieve spring tension by loosening
the locknut and turning the adjustment screw
counterclockwise. 2. Unscrew hex head screws and remove spring
case housing. 3. Disconnect diaphragm from lever, connector head
and disassemble complete diaphragm
assembly. 4. Reassemble using a new diaphragm with the following
cautions in mind:
Connector head is engaged to lever Diaphragm is centered
Diaphragm is not twisted
5. Tighten the spring case housing hex head screws finger tight
only. Tighten the adjusting screw until it begins to stretch the
diaphragm, then 2 more turns.
6. Tighten the spring case housing hex head screws.
