Things to tell the gas customer:
1. Show the customer the vent or vent assembly or vent
tube. Stress that this opening must remain unobstructed
at all times. Tell the customer to check the vent opening
after a freezing rain, sleet storm or snow to make sure
ice has not formed in the vent.
2. Show the customer the shutoff valve on the container.
The customer should close this valve immediately if gas
is smelled, appliance pilot lights fail to stay on or appear
higher than usual or any other abnormal situation occurs.
3. Tell the customer to call your company to service the
regulator if the regulator vents gas or a leak develops in
the system. Only a qualified gas service person should
install or service the regulator.
4. Tell the customer to call your company to have a leak
check performed if the gas supply has been shutoff
or interrupted for any reason. A leak check must be
performed by a qualified gas service person on the piping
system immediately after turning on the gas supply.

Description
First Stage and 2 psig / 0.14 bar
Service Regulators
The Types R622H, R622E and R652E regulators are designed
for high pressure (pounds per square inch) vapor service. These
regulators have high capacity internal relief valves.
When used on first stage service, the Type R622H regulator
reduces container pressure to 10 psig / 0.69 bar for a second
stage regulator. On final stage service the regulator reduces
container pressure for a high pressure burner. The regulator is
normally painted RED.
2
The Type R622E or R652E standard outlet pressure setting is
2 psig / 0.14 bar. The regulator is painted PALM GREEN with a
WHITE CAP. It is an intermediate stage regulator that reduces
10 psig / 0.69 bar first stage pressure to 2 psig / 0.14 bar.
They are used on 2 psig / 0.14 bar pressure systems. The
Types R622E and R652E are not suitable for first stage service.
Second Stage Low Pressure Regulators
The Types R622, R642, R652 and HSRL Series regulators
provide low pressure (inches of water column) delivery
pressures. They are normally set at 11 in. w.c. / 27 mbar
pressure. They have high capacity internal relief valve
construction. The regulators are normally painted PALM
GREEN. The units differ in construction and capacity rating.
R600 and HSRL Series LP-Gas Regulators
Integral Two-stage Regulator
The Type R632A integral two-stage regulator contains a
non-adjustable first stage regulator on the inlet. The second
stage provides 11 in. w.c. / 27 mbar outlet pressure. The
second stage portion has a high capacity internal relief valve
construction. The first stage does not have an internal relief
valve. The regulators are normally painted GRAY with a
BLACK CAP.
Integral Two psig Service Regulator
The Type R632E integral two psig service regulator contains
a non-adjustable first stage regulator on the inlet. The
second stage provides 2 psig / 0.14 bar outlet pressure. The
second stage portion has a high capacity internal relief valve
construction. The first stage does not have an internal relief
valve. The regulators are normally painted GRAY with a
WHITE CAP and White 2-psig STICKER.

Installation
WARNING
!
All vents should be kept open to permit free
flow of air in and out of the regulator. Protect
vent openings against the entrance of rain,
snow, ice formation, paint, mud, insects,
water from an irrigation system or any other
foreign material that could plug the vent or
vent line or accumulate in the vent line.
LP-Gas may discharge to the atmosphere
through the vent. An obstructed vent which
limits air or gas flow can cause abnormally
high pressure that could result in personal
injury or property damage. Failure to use a
vent line on Indoor Installations can cause a
hazardous accumulation of gas which could
result in personal injury or property damage.
Types R622H, R622E, R632A, R632E and
R652E regulators are not suitable for
indoor installations.
Never use a Type R622H, R622E, R632E or
R652E (pounds-to-pounds) regulator on low
pressure (inches of water column) service
T14446-A2
Figure 2. Regulator with Vent Pointed Down
because personal injury or property damage
could occur. The Types R622E and R652E are
not suitable for use as a “first stage” regulator.
General Installation Instructions
Before installing the regulator,
• Check for damage, which might have occurred
in shipment.
• Check for and remove any dirt or foreign material, which
may have accumulated in the regulator body.
• Replace old pigtails. Blow out any debris, dirt or copper
sulfate in the copper tubing and the pipeline.
• Apply pipe compound to the male threads of the pipe
before installing the regulator.
• Make sure gas flow through the regulator is in the same
direction as the arrow on the body. “Inlet” and “Outlet”
connections are clearly marked.

Installation Location
• The installed regulator should be adequately protected from
vehicular traffic and damage from other external sources.
• Install the regulator with the vent pointed vertically down,
see Figure 2. If the vent cannot be installed in a vertically
down position, the regulator must be installed under a
separate protective cover. Installing the regulator with the
vent down allows condensation to drain, minimizes the
entry of water or other debris from entering the vent and
minimizes vent blockage from freezing precipitation.
4
• Do not install the regulator in a location where there can
be excessive water accumulation or ice formation, such
as directly beneath a down spout, gutter or roof line of
building. Even a protective hood may not provide adequate
protection in these instances.
• Install the regulator so that any gas discharge through the
vent or vent assembly is over 3 ft / 0.91 m horizontally from
any building opening below the level of discharge.
• Install the regulator high enough above ground level at
least 18 in. / 45 cm - so that rain splatter cannot freeze
in the vent.

T14447-A2
Figure 3. Tank Installation
Regulators Subjected to Heavy
Snow Conditions
Some installations, such as in areas with heavy snowfall,
may require a hood or enclosure to protect the regulator from
snow load and vent freeze over.
Horizontally Installed Regulators
Horizontally mounted regulators, such as found in single
cylinder installations and ASME tanks, must be installed
beneath a protective cover or under the ASME tank dome,
refer to Figure 3. If possible, slope or turn the vent down
sufficiently to allow any condensation to drain out of the
spring case. Be careful that the slot in the tank dome or
protective cover for the regulator’s outlet piping does not
expose the vent to the elements. The first stage vent on the
Types R632A and R632E should be pointed down.
Meter Installations
Type R642 regulators have an angle body that makes it easy
to install on to a gas meter instead of piping leading directly
into a building.

Indoor Installations
By code, regulators installed indoors have limited inlet
pressure and they require a vent line to the outside of the
building, see Figure 4. A vent assembly, such as
Fisher® Y602 Series, should be used on the end of the vent
line. The same installation precautions, previously discussed
throughout this manual for the regulator vent, apply to the
end of the vent tube assembly. Vent lines must not restrict
the gas flow from the regulator’s internal relief valve. Vent
lines should be at least 3/4 in. NPT pipe or 3/4 in. NPT size
PVC Schedule 40 Rigid Conduit, meeting the requirements
of Underwriters Laboratories (UL®) 651. To install the vent
line, remove the vent screen and apply a good grade of pipe
dope to the male threads of the line. Vent lines should be as
straight as possible with a minimum number of bends.
Underground Installations
WARNING
!
Types R632A and R632E integral regulators
require 2 vent tubes, one on the first stage
vent and one on the second stage vent, when
installed on underground tanks. Failure to
use 2 separate vent tubes can result in early
regulator failure and/or over pressuring the
second stage that could result in fires or
personal injury.
Regulators installed in the dome of an underground
container require a vent tube to prevent water from entering
the regulator spring case, see Figure 5.
Note
Types R632A and R632E integral regulators
installed on underground tanks require the
use of 2 vent tubes, one for the first stage
vent (1/4 in. OD copper tube inverted flare
connection: 7/16-24 UN thread) and the other
for the second stage vent (3/4 in. NPT) of
the regulator.
Remove the vent screens and install vent tubes. The vent
tube must be run from the regulator vent to above the
maximum water table. The vent tube opening must terminate
at the extreme top inside of the dome cover. Make sure the
regulator’s closing cap is on tightly, and maintain drainage
away from the dome at all times.
Outdoor Installations with Underground
Vent Lines
When installed per code, the underground vent line must not
restrict the gas flow from the regulator’s internal relief valve
and must remain clear of debris, dry and fully open at all
times. Joints in the vent line must be fully sealed to prevent
moisture intrusion into the vent line. A vent assembly, such
as the Fisher Y602 Series, should be used on the end of
the vent line to prevent entry of precipitation, water or other
debris. When underground vent lines are used in humid
environments, the vent line must be designed to allow for
proper drainage of any collected moisture or condensation.
Adjustment
Each regulator is factory set. If it becomes necessary to
increase the outlet pressure, remove the closing cap and
turn the adjustment screw clockwise. Turn the adjusting
screw counterclockwise to decrease the outlet pressure. The
first stage portion of the Types R632A and R632E integral
regulators is non-adjustable.
6
R600 and HSRL Series LP-Gas Regulators
The inlet and outlet pressure plug may be removed using
a 7/16 in. / 11 mm hexagon wrench. The pressure tap is
restricted, so the plug can be removed with pressure on the
outlet of the regulator. Install a pressure gauge to determine
the regulator’s inlet pressure and outlet setting during
adjustment, (actual pressure at the second stage regulator
may be less due to line loss). After setting, add thread sealant
to the 1/8 in. NPT pipe plugs. Reinstall the pipe plugs by
threading into the gauge ports finger-tight and then wrench
tighten 1-1/2 to 3 turns past finger-tight (approximate maximum
torque of 12 ft-lb / 16 N•m). Replace the closing cap. Check
the pipe plugs for leakage.
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 above the
limits shown in the Specifications section
may cause damage to regulator parts, leaks
in the regulator or personal injury due to
bursting of pressure-containing parts or
explosion of accumulated gas.
If any portion of the regulator is exposed to
an overpressure condition that exceeds the
limits in the Specifications section, it must be
inspected for damage that may have occurred.
Large volumes of gas may discharge through
the regulator vent during internal relief valve
operation, which can, if not controlled, result
in fire or explosion from accumulated gas.
The R600 and HSRL Series regulators, except for the
first stage of the Types R632A and R632E, contain internal
relief valves. The internal relief valve in all units will
give overpressure protection against excessive build-up
resulting from seat leakage due to worn parts or chips or
foreign material on the orifice. The amount of internal relief
protection provided varies with the regulator type and the
cause for the overpressure relief valve operation. When the
internal relief valve opens, gas escapes to the atmosphere
through the regulator’s vent.
Some type of additional external overpressure protection
must be provided if the outlet pressure in an overpressure
condition exceeds the inlet pressure rating of the gas system
or downstream equipment. Common methods of external
overpressure protection include relief valves, monitoring
regulators, shutoff devices and series regulation.
Maintenance
WARNING
!
To avoid personal injury or equipment
damage, do not attempt any maintenance
or disassembly without first isolating the
regulator from system pressure and relieving
all internal pressure.
Regulators that have been disassembled for
repair must be tested for proper operation
before being returned to service. Only parts
manufactured by Fisher® should be used for
repairing Fisher regulators. Relight pilot lights
according to normal startup procedures.
Due to normal wear or damage that
may occur from external sources, these
regulators must be inspected and maintained
periodically. The frequency of inspection
and replacement of the regulators depends
upon the severity of service conditions or
the requirements of local, state and federal
regulations. Even under ideal conditions,
these regulators should be replaced after
20 years from date of manufacture or sooner
should inspection reveal the need.
Failure to replace a regulator that has had water
inside due to flooding, water table level or
weather events or has corrosion present could
result in personal injury or property damage.
Visually inspect the regulator each time a gas delivery is
made for:
• Improper installation, vent not pointed vertically down or
under a cover; no vent tube on underground systems
• Plugged or frozen vent
• Wrong regulator or no regulator in the system
• Internal or external corrosion, including paint chipping
or flaking
• Flooded Regulator; water in spring case; regulator
submersed on underground tanks
• Regulator age
• Any other condition that could cause the uncontrolled
escape of gas
7
R600 and HSRL Series LP-Gas Regulators
Vent Opening
Make sure the regulator vent, vent assembly or vent tube does
not become plugged by mud, insects, ice, snow, paint, etc. The
vent screen aids in keeping the vent from becoming plugged
and the screen should be clean and properly installed. Make
sure any irrigation system operated near a regulator or vent line
does not spray water into the vent opening of the regulator or
vent assembly.
Water Inside Regulators from
Floods, Weather or Water Table on
Underground Systems
Replace any regulator that had water in their spring case,
has been flooded, has been submersed below the water
table of an underground tank or shows evidence of external
or internal corrosion. Checking for internal corrosion can
be done by removing the closing cap and with the aid of a
flashlight observing the condition of the relief valve spring,
main spring and internal spring barrel area. A more detailed
examination will require shutting down of the gas system
and the complete removal of the adjusting screw. Closely
examine regulators installed with their vent horizontal for
signs of corrosion. Correct any improper installations.
Regulator Replacement
Older regulators are more likely to catastrophically fail
because of worn or corroded parts. Replace R600 and
HSRL Series regulators over 20 years of age. Other service
or environmental conditions may dictate replacement of the
regulator before it becomes 20 years old. Regulators that are
installed in corrosive environments including but not limited
to the following conditions should be inspected annually
for visual indication of external or internal corrosion and
paint chipping or flaking. Regulators in these applications
may require replacement sooner and must be replaced if
corrosion is evident:
• Regulators that are installed in areas subject to sea salt
(coastal) atmosphere
• Regulators that are installed on underground systems
• Regulators installed with underground vent piping
• Regulators that are used in installations where the gas
system is only operated and pressurized intermittently
®
Refer to Fisher
Bulletin LP-32 for additional information.
Regulator Repair
Regulators that have been disassembled for repair must be
tested for proper operation before being returned to service.
Only parts manufactured by Fisher should be used to repair
Fisher regulators. Be sure to give the complete type number
of the regulator when corresponding with the factory.
The type number, orifice size and spring range are on a label
attached to the spring barrel. The date of manufacture is
stamped on the regulator. Always provide this information in
any correspondence with your Fisher Distributor regarding
replacement parts or technical assistance. If construction
changes are made in the field, be sure that the regulator
marking is also changed to reflect the most recent construction.
