Instruction manual

Complete information regarding tank sizing for vaporization,
recommended regulator settings, and pipe sizing is available
from most regulator manufacturers and propane gas suppliers.
Since propane gas will quickly dissolve white lead and most
standard commercial compounds, special pipe dope must be
used. Shellac-based compounds resistant to the actions of
liquefied petroleum gases, such as Gasolac
®
, Stalactic
®
, Clyde’s
®
or John Crane
®
are satisfactory.
Refer to “Propane Gas Installation—Typical” for typical propane
gas installations and piping.

Stage Regulator*
Maximum propane capacities listed are based on 2 psig pressure drop at 10 psig setting. Capacities in 1,000 Btu/h.
To convert to capacities at 15 psig settings—multiply by 1.13. To convert to capacities at 5 psig settings—multiply by 0.879.
Sizing Between Single or 2
