C. Examination and Cleaning of Flue, Burner and Jet
Once or twice a year, look through the opening (see FIG.
9) in the burner box and examine the appearance of the
burner flame which should be predominantly blue in
color when the gas thermostat knob is set to its highest
position. (Refer to FIG. 10).
If this is not the case, clean the flue, burner, jet, etc. (see
section D and E).

D. Cleaning of Burner, Burner Jet (Refer to FIG. 11)
Proceed as follows:
1) Turn off the gas at the gas bottle.
2) By using a phillips screwdriver, remove the screw (B)
and carefully withdraw the burner cover box. Clean
the inside of the box of soot and other deposits.
3) To clean the burner, unscrew the screw (C) that fixes
the burner on the boiler tube and be careful in order
not to lose the washer.
4) Clean the inside of the burner.
5) To examine and eventually clean the burner jet,
unscrew the gas pipe union (K) and pull out the
burner jet (L).
6) Clean the jet by washing it in alcohol and blowing it
through with air.
NOTE: The jet fitted to this refrigerator is a size
"45" which is suitable for use on propane gas at
11 inches water column. The orifice in the jet is
very small and must never be cleaned by means
of a pin or similar instrument as this would
damage the orifice. It must only be cleaned as
described above.
CAUTION!
DO NOT use a wire or pin when
cleaning the burner jet as damage
can occur to the precision ope-
ning. This can cause damage to
the refrigerator or create a fire
hazard.
7) Reassemble the components in the reverse order to
that described above.
