could result in an explosion and/or fire
causing property damage and personal injury
or death.
Fisher® equipment must be installed,
operated and maintained in accordance with
federal, state and local codes and Fisher
instructions. The installation in most states
must also comply with NFPA No. 54 and
58 standards.

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.
