R600 and HSRL Series Instruction Manual

WARNING

Failure to follow these instructions or

to properly install and maintain this

equipment could result in an explosion

and/or  re 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.

Only personnel trained in the proper

procedures, codes, standards, and

regulations of the LP-Gas industry should

install and service this equipment.

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 quali ed gas service person

should install or service the regulator.

Introduction

Scope of the Manual

This Instruction Manual covers Installation and

Maintenance for the R600 and HSRL Series regulators,

which includes  rst stage, second stage, two psig service,

integral two- stage and integral two psig service regulators

used on LP-Gas vapor service applications. They are not

to be used on liquid service.

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  rst stage service, the Type R622H

regulator reduces container pressure to 10 psig / 0.69 bar

for a second stage regulator. On  nal stage service the

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-inches 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.

Tank Installation 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. • • • 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.

THIS PREVENTS WATER COLLECTING AND RUNNING INTO OR STANDING AROUND HOUSING DOME. 2 INCHES / 5.1 cm MINIMUM REGULATOR ADJUSTMENT CLOSURE CAP MUST BE TIGHT. WATER MARK LEFT IN HOUSING DOME AT LEVEL ABOVE REGULATOR VENT, OR END OF VENT TUBE REQUIRES REPLACEMENT OF REGULATOR. INSTALL REGULATOR PROPERLY. T14448-A2 Figure 5.

R600 and HSRL Series LP-Gas Regulators Make sure the regulator’s closing cap is on tightly, and maintain drainage away from the dome at all times. 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.
