SECTION 3. OPERA TION
3-1. OPERA TING COMPONENTS
COOK/PUMP Switch A three way switch with center OFF position; move the switch to
the position marked COOK to operate the fryer; move the switch
to the position marked PUMP to operate the filter pump; certain
conditions must be met prior to operation of the filter pump; these
conditions are covered later in this section
Frypot This reservoir holds the cooking shortening, and is designed to
accommodate the burner tubes, 8 head of product and an
adequate cold zone for collection of cracklings
Carrier This stainless steel carrier consists of five racks which contain
the food product during and after frying
Drain V alve A two-way ball valve, normally in the closed position; turn the
handle to drain the shortening from the frypot into the filter drain
pan
Drain Interlock Switch A microswitch that provides protection for the frypot in the event an
operator inadvertently drains the shortening from the frypot while
the main switch is in the COOK position; the switch is designed to
automatically shut off the heat when the drain valve is opened
Shortening Mixing System A shortening mixing capability to help ensure shortening is properly
mixed to prevent an accumulation of moisture and hence boiling
action in the pot; the filter pump is activated by the controls, at
preset intervals, to mix the shortening
Lid Latch A mechanical catch on the front of the lid which engages a bracket
on the front of the frypot; this device holds the lid down while the lid
is being locked into place, but is not to hold pressure in the frypot
Ignition Modules The two ignition modules send 24 volts to the gas control valve and
high voltage to the ignitors
Spark Ignitors When the pilots are being lit, the spark ignitors are electrically
energized and the tip of the ignitors spark to ignite the pilot lights

High Limit This high temperature control senses the temperature of the
shortening; if the temperature of the shortening exceeds
450°F (230°C), this control will open and shut off the heat
to the frypot; when the temperature of the shortening drops
to a safe operation limit, the control must be manually reset by
pressing the red reset button, located under the control panel, in the
front of the fryer
Figure 3-1
Flame Sensors Sense the pilot lights when the power switch is turned on; if the
pilots go out, or do not light, the flame sensors shutd the gas off, via
the modules
Gas Control Valve A dual controller, in which, one side of the valve controls the pilot
light and the other side controls the main burner.
Airflow Switch Senses the flow of air coming from the blower; if the airflow is
reduced below a set amount, the switch cuts power to the gas
control valve, which shuts down the burners
Blower Adds the proper amount of air into the burner tubes, so an efficient
combustion takes place, and also, pulls the flue gases out to the flue
Air V alve Pumps air into the shortening, periodically , to keep the shortening at
a uniform temperature; this only functions when the unit has been
sitting idle for a period of time, and when heating upfrom a cold
start
Filter Drain Pan The removable pan that houses the filter and catches the shortening
when it is drained from the frypot; also used to remove anddiscard
old shortening
When hot shortening is in this pan, use extreme care to
avoid burns.
Filter Union Connects the filter to the filter pump, and allows easy removal of the
filter and drain pan

3-5. FILLING OR ADDING
SHORTENING
Model OFG- 391
The shortening level must always be above the heating
elements when the fryer is heating and at the frypot level
indicators on the rear of the frypot (Figure 3-3). Failure
to follow these instructions could result in a fire and/or
damage to the fryer.
When using solid shortening, it is recommended to melt
the shortening on an outside heating source before placing it in the frypots. The burner tubes must be completely
submerged in shortening. Fire or damage to the frypot
could result.
1. It is recommended that a high quality frying shortening
be used in the open fryer . Some low grade shortenings have a
high moisture content and will cause foaming and boiling over .
Figure 3-3
T o avoid severe burns when pouring hot shortening
into frypot, wear gloves and take care to avoid
splashing.
2. The gas model requires 130 lbs. (59 Kg.) The frypot has
4 level indicator lines inscribed on the rear wall of the
frypot which show when the heated shortening is at the
proper level. Figure 3-3.
3. Cold shortening should be filled to the lower indicators.
BE CERT AIN THE SHORTENING IS NEVER
ABOVE THE UPPER LEVEL INDICA TOR LINES.
FAILURE TO FOLLOW THESE INSTRUCTIONS
CAN RESUL T IN SHOR TENING OVERFLOWING
THE FRYPOT CAUSING SERIOUS BURNS, PERSONAL INJUR Y , FIRE AND/OR PROPERTY
DAMAGE.

3-6. PRODUCT RACKING
RECOMMENDATIONS The rack positions are referenced starting at the bottom:
4 _____________
3 _____________
2 _____________
1 _____________
The bottom position is to be avoided on small loads because it is
closer to the cold zone. (The oil is cooler at the bottom of the frypot
and hotter at the top.) W ith bigger loads, however, there is generally
enough turbulence in the oil that the bottom rack gets sufficient heat.
The top position is to be avoided on small loads because of
insufficient oil coverage. W ith bigger loads, the top rack has good
oil coverage because the volume of product on the lower racks
raises the overall oil level.

3-7. BASIC OPERA TION Follow the procedures below on the initial start-up of the fryer, and
each time the fryer is brought from a cold, or shut down condition.
1. Make sure the frypot is filled with shortening to the 2 lower
level indicators
DO NOT OVERLOAD, OR PLACE PRODUCT WITH
EXTREME MOISTURE CONTENT INTO THE
RACKS. 20 LBS. (9.0 KG.) IS THE MAXIMUM
AMOUNT OF PRODUCT PER FR YPOT . FAILURE
TO FOLLOW THESE INSTRUCTIONS CAN RE
SUL T IN SHOR TENING OVERFLOWING THE
FRYPOT WHICH COULD CAUSE SERIOUS
BURNS, PERSONAL INJUR Y, FIRE AND/OR
PROPERTY DAMAGE.
2. Turn the COOK/PUMP switch to the COOK position and
press the appropriate product button to select the amount of
product to be cooked. Unit automatically goes into the
Melt Cycle. When temperature reaches 250° F (121° C) the
controls goes into the Heat Cycle, and heats the shortening to
the setpoint temperature.
All safety devices shut off the gas supply to the burner .
Follow the above procedures to restart the fryer . Notify a
qualified service technician if the shut down is repeated.
3. Stir the shortening as it’ s heating up from a “cold” start.
Be sure to stir down into the “cold zone”.
DO NOT STIR THE SHOR TENING A T ANY OTHER
TIME EXCEPT AT MORNING START-UP . FAILURE TO FOLLOW THESE INSTRUCTIONS CAN
RESUL T IN SHOR TENING OVERFLOWING THE
FRYPOT WHICH COULD CAUSE SERIOUS
BURNS, PERSONAL INJURY, FIRE, AND/OR
PROPERTY DAMAGE

3-7. BASIC OPERA TION 4. Allow fryer to heat until illuminates.
(Continued)
Bypass the Melt Cycle, if desired, by pressing a product
button and holding it for five seconds. The display shows
“EXIT MELT? 1=YES 2=NO”. Press to exit melt.
In the event of a power failure, no attempt should be made to
operate the fryer. The fryer is equipped with an automatic
ignition system and cannot be operated without electrical
power.
Do not bypass the Melt Cycle unless enough shortening
has melted to completely cover all of the burner tubes.
If the Melt Cycle is bypassed before all buner tubes
are covered, excessive smoking of shortening, or a fire
could result.
The heat cycles on and off about 10 degrees before the
setpoint temperature, to help prevent overshooting the
setpoint temperature. (proportional control)
Once out of the Melt Cycle, flashes until 5° before setpoint
temperature is reached. Then illuminates and the selected
product shows in the display .
5. Before loading product onto the racks, lower the racks
into the hot shortening to prevent the product sticking to
the racks.
6. Slide racks of breaded product into carrier on the lid,
starting with the bottom rack, to prevent damaged product.
7. Lower and latch the lid, and press .
A different product can be selected during the first minute of
cooking, in case the wrong product button was pressed. T o
check the shortening temperature press or to stop a
Cook Cycle, press .
8. At the end of the cycle, an alarm sounds, while the display
shows “DONE”. Then press .

10. Using the rack handles, remove the racks of product from
the carrier, starting with the top rack, to prevent damaged
product.
1 1 . If a Quality time (hold time) was programmed, the controller
automatically starts the hold timer. The display alternately
shows the product selected and the quality time remaining in
minutes. If a different product is selected during the Hold
Cycle, the display only shows the product selected.
12. At the end of the Hold Mode, a tone sounds, the display
flashes “QUALITY”, and the product it was timing. Press
and release .
In the Cook Mode, when “FILTER SUGGESTED”, shows in
the display , the operator has the option to filter at this time, or
to continue cooking. But, if the operator continues cooking, a
Filter Lockout occurs within the next Cook Cycle, or two.
Model OFG- 391
When “FILTER LOCKOUT” , then “YOU *MUST* FILTER
NOW........” shows in the display, is the only button that
functions, until the unit is filtered. Follow the filtering instructions in
this manual.
Once filtering is complete and the COOK/PUMP switch is turned
back on, “IS POT FILLED” shows in the display, followed by
“1=YES 2=NO”.
If shortening is at the proper level in the frypot, press and
the controls start a normal heating process.
If shortening is NOT at the proper level, press and “TURN
OFF UNTIL FILLED…” scrolls through the display. Turn the
COOK/PUMP switch to the OFF position, fill frypot to the proper
level, then turn the COOK/PUMP switch back to the COOK
position.
Again, “IS POT FILLED” shows in the display , followed by
“1=YES 2=NO”. This time press and unit resumes
normal heating process.

3-8. CARE OF THE
SHORTENING
Model OFG- 391
FOLLOW THE INSTRUCTIONS BELOW TO A V OID
SHORTENING OVERFLOWING THE FR YPOT ,
WHICH COULD RESUL T IN SERIOUS BURNS,
PERSONAL INJUR Y , FIRE, AND/OR PROPERTY
DAMAGE.
1. T o protect the shortening when the fryer is not in immediate
use, the fryer should be put into the Idle Mode.
2. Frying breaded products requires filtering to keep the
shortening clean. The shortening should be filtered at
least twice a day; after lunch rush and at the end of the day .
3. Maintain the shortening at the proper cooking level. Add
fresh shortening as needed.
4. Do not overload the baskets with product (20 lb (9.0 kg)
max), or place product with extreme moisture content into
baskets.
WITH PROLONGED USE, THE FLASHPOINT OF
SHORTENING IS REDUCED. DISCARD SHORTENING IF IT SHOWS SIGNS OF EXCESSIVE
SMOKING OR FOAMING. SERIOUS BURNS,
PERSONAL INJUR Y , FIRE, AND/OR PROPERTY
DAMAGE COULD RESUL T .
3-9. FIL TERING The Henny Penny gas 8 head fryer , Model OFG-391, must be
INSTRUCTIONS cleaned and the shortening filtered at least twice daily; after lunch
rush and at the end of the day .
Drain the shortening at 275° F (135° C) or less. The
higher temperatures cause cracklings to burn on the
steel frypot surfaces after the shortening has drained.
