1. Point out the regulator’s vent to the customer (or
vent assembly or vent tube), and
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

regulator. If the regulator vents gas or a leak
develops in the system, only a qualied gas
serviceman should install or service the regulator.
This instruction manual covers installation and
maintenance for the following high or low-pressure
regulators: Types 912N, 912H, Y200N, Y200H,
and R922N.
The Types 912H and Y200H regulators are designed for
high-pressure (pounds per square inch) vapor service
and are not to be used for liquid service. Both are U.L.
listed, and they are normally painted red.
Types 912N, Y200N, and R922N can be used for either
high-pressure or low-pressure (inches of water column)
service. They are not to be used for liquid service. “N”
sufx regulators are not U.L. listed and are normally
painted gray (low-pressure) or red (high-pressure).
The Specications table lists the specications for the
regulators. Contact the factory if the regulators are to be
used on any service other than LP-Gas, Natural Gas, or
Air. Temperature limits are -20° to 160°F (-29° to 71°C).
Maximum inlet pressure is 250 psig (17,2 bar).
