Operations and Maintenance Manual
3.3
Gasoline Burner Unit
The
sterilizer
has
a cavity
designed
to
accept the gasoline burner unit used with
the
US
Army
field range.
The
gasoline
burner is a US National stock N27310-01-113-
9172.
The burner unit uses any gasoline,
leaded or unleaded.
A pump is needed for
creating the necessary air pressure in the
tanks. Check the burner unit for leaks under
air pressure before filling it with gasoline.
Both sides of the sterilizer fire box have a
door to permit the burner unit to be inserted
from
either
side.
These
doors
have
an
adjustable
chain
to
hold
them
partially
closed, if required, to shield the burner from
a strong wind.

OPERATING INSTRUCTIONS
4.1
Filling With Water
If the sterilizer is operated on electric power
or gasoline heat, fill the jacket with water as
pure as possible.
Check the jacket at every
cycle.
Do not start a new cycle if the jacket
contains less than
1/2 of its volume
water.
If the sterilizer is allowed to run dry, the low
water shutoff will trip, interrupting the cycle.
Use of distilled water is preferred because it
results in less frequent cleaning of the jacket
interior.
To fill with water:
1.)
Remove
the
plug
from
the
filling
funnel.
2.)
Turn
the
operating
valve
to
the
sterilize position.
3.)
Fill the jacket with water through the
funnel until the sight glass shows full.
4.)
Turn the operating valve to off.
5.)
Replace the plug in the funnel.
