Outer surface of vaporizer should be kept free of dirt
and debris accumulation, which will cause a loss of
vaporization effi ciency. Visual inspection and necessary
cleaning should be performed on a regular basis, more
frequently under dusty or dirty conditions.
LPG/NG REGULATOR
Regulator controls both pressure and fl ow of fuel within
LPG/NG system. It is comprised of both a primary and
secondary chamber, which are dependent upon one
another. Two diff erent styles of regulators are used,
based upon system involved. Although basic design
and operating principles are similar, due to system
diff erences regulators should not be interchanged.
Following are separate sections covering theory of
operation and general service information for each style
of regulator. Detailed service/repair instructions are
included in rebuild kit for each regulator.
