LPG
System-Liquid
Withdrawal
See Figure 6-26. For liquid withdrawal systems the
LPG container(s) must be equipped to withdraw
LPG as a liquid. See the Installation Manual for im-
portant recommendations regarding the installation
of a LPG liquid withdrawal type of fuel supply sys-
tem.
IAWARNINGI LPG
is
flammable
and
explosive
and
can cause asphyxiation. NFPA 58, Section
1.6 requires
all
persons
handling
LPG
to
be
trained
in
proper
handling
and
operating
proce-
dures.
It is important to understand that the fuel filter, sole-
noid shutoff valve, vaporizer and demand regulator
handle LPG liquid at the same pressure as in the
LPG container. Depending on ambient tempera-
ture, LPG container pressure can exceed 200 psi
(1379 kPa). Therefore, discharge
or
leakage from
LPG liquid-containing components can result in the
escape of large volumes of flammable and explo-
sive gas.
Purging
the LPG System: It is imperative that the
LPG system be purged before disconnecting fuel
system components.
IAWARNINGI Large volumes
of
LPG
can
be
re-
leased
in
the
process
of
disconnecting
a
liquid-
withdrawal type
of
LPG
supply
system. See the
instructions
in
Section 5. Preparing
to
Service
for
proper
procedures
and
precautions
when
disconnecting
LPG
fuel
lines.
