ADJUSTMENTS AND TROUBLE SHOOTING
Adjustments
The burner used on your GARLAND Fryer is a patented
design which does not require primary air, so no primary air
adjustment is possible. When the proper gas is being used,
at the proper pressure, and the ceramic targets are adjusted
properly, combustion will begin about even with the bottom
of the ceramic. The sound that is characteristic is a low roar,
similar to a blowtorch.
The correct type of gas and BTU content for which the fryer
was equipped at the factory is noted on the nameplate, and
this gas must be used.
NEVER THROTTLE DOWN THE INCOMING GAS IN AN EFFORT
TO MAKE THE FLAME BURN DIRECTLY ON THE ORIFICE.
A piece of mechanical equipment which is used as hard as
a deep fat fryer is going to require service as the fryer gets
older; therefore, the following chart outlines problems that
are most likely to occur and what to do to correct them.
There are several possible sources of trouble in connection
with the operating thermostat. Usually the trouble will be
noticed by either the thermostat not causing the gas valve
to open, or by causing it to open at the wrong temperature.
It opens the gas valve at the wrong temperature, it is said to
be out of calibration. If all the other parts of the appliance are
operation as they should, the following chart will help locate
the source of trouble and

Thermostat Calibration Instructions
To calibrate the Fenwal Thermostat, fill the frypot to the FULL
mark with frying compound and turn the burner on. Insert a
thermometer in the center of the frypot with the bulb about
two inches below the surface. Allow the burner to cycle
about four times, the thermometer reading should be within
5° of the thermostat knob setting. If this does not agree with
the pointer of the thermostat knob.
1. Loosen the two set screws on the thermostat knob,
2. Set the pointer at the temperature indicated on the
thermometer,
3. Tighten the set screws firmly.
4. Be sure the black surface of the knob is spaced away from
the dial plate at least the thickness of a dime.
NOTE: Do not turn adjusting shaft more than two turns
in either direction or permanent damage can result. This
action may void the standard warranty.
