B. Check all connections in the LP gas system (at the
back of the refrigerator) for gas
leaks.
The LP gas
supply must be turned on. Apply a
non-corrosive
bubble solution
to all LP gas
connections. The ap-
pearance of bubbles indicates a leak end should be
repaired
immediately
by a QUALIFIED SERVICE-
MAN WHO IS
FAMILIAR
WITH
GAS SYSTEM AND
REFRIGERATORS.

Check the AMES
control system by
connecting/dis-
connecting 120 volt AC power, start/stop the engine,
etc. Compare the operation with the operation de-
scribed
in
description of operating modes. Page

The LP gas pressure should be checked and the
main regulator m-adjusted if pressure is incorrect.
The correct operating pressure is 11 inches of water
column. The correct place to take the LP gas pres-
sure is at the test port just ahead of the
burner
jet.
(See FIG. 12).
Inspect the flue baffle.
It
should
be
reasonably
clean
and free of soot. Heavy soot formation indicates
Improper functioning of the burner. The flue and
burner both require cleaning in the following
manner.
Unplug the refrigerator power cord from the 120 volt
AC outlet. (See FIG. 3).
Disconnect or shut off the 12 volt power to the
refrigerator.
Turn manual shutoff valve
to OFF.
(See FIG. 1).
Remove cover from the bumer housing. (See FIG.
1).
Disconnect
the
wire
from the
high
voltage electrode.
Remove the burner mounting screw end remove the
burner
assembly.
(See
FIG. 12).
Remove the
wire
and flue baffle from the top of
flue
tube. Clean the flue from the top using a flue brush.
Blowing compressed air into the
flue will not
properly
clean soot and scale out of the flue tube. Replace the
flue baffle.
Clean burner tube with a brush.
Blow
out burner with
compressed air.
Before removing burner jet, clean burner area of
soot
and scale
that
fell
out
of
flue
tube. Remove the bumer
jet. Soak the- jet in wood alcohol and Mow it out with
compressed air.
Re-install
and tighten burner jet
NOTE: The color of the flame shall be clear blue over
the slots of the burner. (See FIG.
13).

DO NOT use a wire or
pin
when
cleaning
the burner

occur to the
precision
opening.
This can cause damage to the refrigerator or create
a fire hazard.

Reinstall burner, being
careful
that the end of the
burner fits into the slot on the burner bracket. Check
to make sure
slots
are centered under the flue tube
and the thermocouple is positioned properly (tip of
thermocouple extends over two slots of burner).
Se sure to reconnect the wire to high voltage elec-
trode. Check the electrode for proper location and
gap. (See FIG. 14).
