Type R122H First-Stage Regulator
introduction
The Type R122H is an Underwriters Laboratories listed
regulator designed for Two-Stage LP-Gas systems.
The unit is designed to reduce the tank pressure to an :.
outlet pressure of 10 psig. The compact size makes it
ideal for small domestic applications and underground _
tanks. The outlet pressure setting is nonadjustable
and is factory set at a nominal 10 psig. Screened drip-
lip vents are oriented over the outlet as standard.
Features _ f z
