LGB 2901 - Troubleshooting

Troubleshooting
Problem:
It takes more than
10 minutes
for the
steam
pressure
to reach
1 kg/cm2.
Problem:
The burner
flame is weak.
Cause
1:
Both of these oroblems
are often
due
to
dust
or foreign
materials clog-
ging
the burner
nozzle.
Solution:
Clean
the nozzle
with the burner
nozzle cleaner
included
with the
Frank
S.
li the burner
nozzle clogs
again
shortly after
cleaning,
the
gas
hose
may have some
foreign mate-
rial inside of
it. Remove the
hose
unions,
and
clean the
hose with
water. Dry the
hose
before
eattach-
ing it.
Cause
2:
In
cold
weather,
the burner
may not
have sufficient
gas
pressure
to oper-
ate
properly.
Solution:
Slowly
pour
warm
water into the ten-
der water tank
to raise the
pressure
in
the
gas
reservoir.
(See
Chapter 6,
Step 6
for instructions.)
Car,itionl Never add warer over
4ooc
(1040F)
to the tender warer
tank. Water over 400C will raise the
gas pressure
beyond the design
limits of the burner
(about
3
kg/cm')
and will make it difficult to operate
the burner. Very hot water
could also
12
raise the
gas
pressure
beyond the
safety limit of the
gas
reservoir.
Cause 3:
The
burner
nozzle may
be blocked
by liquid butane that has frozen at
the nozzle.
Solution:
Let the
butane
flow lor
a
few
sec-
onds until it
gasifies.
Problem:
The
burner will not ignite or the
burner
extinguishes
itself
quickly
even
when
there
is
gas
at the
DUrner.
Cause:
The
pressure
in the
gas
reservoir
may
be too
high
due to
hot water in
the tender water tank. When the
gas
reserv^oir
pressure
exceeds about
4
kg/cm', the burner will not ignite
propefly.
Solution:
Open the
gas
valve a small amount,
and
try to ignite the
burner.
lf
that
fails, replace the water in the tender
water tank with cooler water.
Problem:
Detail
parts
fall
off
the
engine.
Solution:
Use two-part epoxy to reattach de-
tail
parts.
