Vaporizer Assembly

The outer surface of the vaporizer should be kept free
of dirt and debris accumulation, which will cause a loss
of vaporization efficiency. Visual inspection and
necessary cleaning should be performed on a regular
basis, more frequently under dusty or dirty conditions.
The vaporizer should be disassembled, cleaned, and
serviced using a rebuild kit every 1500 hours or if a
problem is encountered.
Figure 5A-17.

LPG Regulator

The regulator controls both the pressure and flow of
fuel within the LP system. It is comprised of both a
primary and secondary chamber, which are dependent
upon one another. Two different styles of regulators
are used, based upon the system involved. The Impco
(Beam) regulator is shown in Figure 5A-18, and the
Nikki regulator is shown in Figure 5A-19. Although the
basic design and operating principles are similar, due
to system differences the regulators should not be
interchanged.

Following are separate sections covering the theory of
operation and general service information for each
style of regulator. Detailed service/repair instructions
are included in the rebuild kit for each regulator.
