THINGS TO TELL THE GAS CUSTOMER:
1. Point out the regulator’s vent to the customer (or vent
assembly or vent tube), and stress that this opening must
remain unobstructed at all times. Tell the customer to be
sure 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 qualied gas service person should
install or service the regulator.
Introduction
Scope of the Manual
This manual provides instructions and maintenance for the
following high-pressure regulators: Types 64, 64KB, 64SR,
67CW, 67CH, 67CD, and 67CN regulators.
Description
The 64 and 67C Series direct-operated regulators (Figure 1) are
designed for high-pressure (pounds per square inch) service and can
be used on either vapor applications in LP-Gas, Natural Gas, and Air
or liquid LP-Gas applications. Depending upon type, outlet pressure
ranges from 3 to 135 psig (0,21 to 9,3 bar). Type 64SR can be used
as a First Stage LP-Gas regulator–reducing tank pressure to
10 psig (0,69 bar) for a Second Stage regulator. Type 64KB is the
only regulator in this series suitable for anhydrous ammonia (NH
3
)
service. The regulators are normally painted red.
