the
gas
valve immediately
to avoid
dry burning.
lf
you
wish to continue
running, wait forthe boilerto cool be-
fore adding more water. lf
you
need
water into
a
hot
boiler, the
water
could change to steam in an rapid,
oangerous
manner.
Once the boiler has cooled. oour
water into
the boiler as
indicated in
Steo 3.
lf the butane is completely con-
sumed before
the water, the Frank
S. will
gradually
slow down and stop.
Close the throttle
valve
and
the
gas
valve. Inject more butane as indi-
cated in Steo 5.
Because the Frank S. uses a dis-
placement
lubrication
system,
the
oil
tank will be filled with a mixture of oil
and
water
after operation. Siphon
the oil and water out of the oil tank
after
every
operation. Refill the oil
tank with fresh steam cylinder oil.
Step
12:
Operation
in
Level Track
The Frank S. can haul 4 to 6 LGB
coaches on a
level track with no
grade greater
than 1% at steam
pre,ssure
levels from 1.0 to 1.5 kg/
cm'. Adjust the throttle valve to
maintain a oressure
level
of
1.0 to
1.5 ko/cm2.
Step 13:
Operation on
Sloped
Track
lf there
are
grades
from 1% to
37" on
your
layout and if
you
also wish to
haul 4
to 6
LGB
coaches, a steam
pressure
level
of
about 2.0 kg/cm2
must be maintained. To maintain
that
steam
pressure,
the burner
must have sufficient
gas
pressure,
and
the temperature
of
the water in
the tender
water
tank should be
25
to
300C,
as
explained
in Step 6.
ln the winter, the water in the tender
water tank will cool faster, and the
gas
pressure
will fall faster. When
this happens, the sound of the
burner
will
change.
To
offset
that
de-
pressurization
of the
gas
reservoir,
slowly add
warm water
to the
tender
water tank.
Caution!
Never
add
water
over
4ooc
(1o4oD
to the tender water
tank.
Also,
experiment
with
the
throttle
valve
to find
the
correct
opening
necessary
to
maintain
a steam
pres-
sure level
of 2kglcm'.
-
Locate the reverser
in the neutral
oosition.
-
When the steam Dressure
is more
than 2.5
kglcm2,
open
the throttle
valve fully and try to expelthe oiland
water condensation
from the cylin-
ders by operating
the reverser
for-
ward and backwards.
wait 10 to 20
seconds between
switchinq back
and forth.
-
When the drain
is
almost com-
pletely
expelled,
let the Frank S. run,
locating the
reverser
somewhere
between
the full forward and neutral
oositions.
-
When the Frank S. reaches an uo
grade,
locate the
reverser
at
the full
forward
oosition.
and as soon as the
Frank S. starts to
go
down
the
grade,
move the reverser closer to the
neu-
tral
position.
On
layouts with
grades,
effective
control of both
the
steam
and
gas pressure
is important for
good performance.
Maintenance
For
your
safety
and enjoyment,
these maintenance
orocedures
should
be followed
at the end
of
each operating
session:
1. lf the Frank
S. is stained
with oil,
water
or dirt, wipe
it clean with
rags
or
towels.
2.
Siphon any remaining
water
out
of the
drain tank. The
drain tank
may be
empty due to the
heat
from
the burner,
but check for
a
dry tank
by opening
the
smokebox door.
3.
When
the boiler is
cool, unscrew
the water
plug
and the
safety
valve,
and drain
any remaining
water from
the boiler.
4.
Siphon the
oil and water
out of
the
oil tank after
every operation.
Refill the
oil tank with f resh
stdam
cvlinder
oil.
Radio
Control
Installation
The Frank
S. does
not
come
equip-
ped
with
radio
control
equipment,
but
it does
have
the
necessarv
space for
mounting
the servo
motor
in
the right
side tank
of the
engine
and
for mounting
the
batteries
and
receiver
in the
tender.
A
one-channel
radio
control
set
coupled
with
a
single
servo motor
is
all that is
needed
to
operate
the
Frank
S.
by radio
control. The
servo
simply
controls
the reverser
which
can
be
used to
control
both
speed
and
direction.
The reverser
stroke
is
12
mm.
Refer
to Figure
10
for installation
in-
structions
for
the R/C
equipment.

5. Pour
the water
out of the tender
water tank.
6.
Release
the
gas
valve
to let the
remaining
butane out
of
the
gas
reservoir.
You may
also store the
remaining
butane in the reser-
voir, if
the Frank
S.
is
kept in a
cool, dark
place
away from
any
open flame
or
heating
equip-
ment.

Radio
Control
Operation
Radio
control of the Frank
S.
is
both
fun
and effective.
This
is especially
true on layouts with many
grades
since
vou
can save
steam on the
I
down slopes and
use the saved
steam on
the
up slopes.
For
radio
control
operation,
begin
with Steps
1 through
I in Chapter
6
and
then
follow
these
instructions:
