SECTION 1. INTRODUCTION
1-1. INTRODUCTION
The Henny Penny Pressure Fryer uses a combination of Pressure,
Heat, and Time to produce a quality product. The advantage of this
type fryer is the pressure allows the product to be cooked with less
heat and less time than the conventional open-type fryers.
The Chick-fil-A controls for the Henny Penny models 500 (electric)
and 600 (gas) have many features to allow the Operator to produce
consistent, quality products. The controls monitor not only cooking
times and temperatures, but also peanut oil condition, product
weights, product temperatures, and many other operational variables. The controls may vary the actual peanut oil temperature and
cook times, based on changes of the operational variables.
The controls also have very extensive self-diagnostic functions
which alert the Operator to both component and procedure
problems.
Some unique features of the fryer are listed below:
• Diagnostic Function-provides summary of fryer and
Operator performance. See section 3-4.
• Alarms and Error Messages-provide immediate feedback for
Operator error or fryer malfunction. See section 3-5.
• Status Mode-allows the Operator to view basic fryer informa-
tion and status. See section 3-4.
• Information Mode-gathers and stores historic information on
the fryer and Operator performance, and can be viewed by the
Operator. See section 3-4.
• Oil Filter Enforcement-prevents the Operator from exceeding
approved number of cook cycles before filtering the peanut oil.
See section 3-4.
• Manual Program Mode-Operator can set time and tempera-
ture for nonstandard products. See section 3-4.
• Easy toggle between English and Spanish operation. See
section 3-4.
• Clean-Out Mode-a preprogrammed function for cleaning the
frypot. See section 3-13.

10. Remove and discard the shipping support. Figure 2-1.
11. Clean the orifice with a dry cloth.
12. Replace the weight and cap.
Figure 2-1
2-2. SELECTING THE
FRYER LOCATION
13. Remove the protective paper from the fryer exterior and clean
with a cloth, soap and water.
The proper location of the fryer is very important for operation,
speed, and convenience. Choose a location which provides easy
loading and unloading without interfering with the final assembly of
food orders. Operators have found that frying from raw to finish, and
holding the product in warmers, provides fast continuous service.
Landing or dumping tables should be provided next to, at least, one
side of the fryer. Keep in mind the best efficiency will be obtained by
a straight line operation, i.e., raw in one side and finished out the other
side. Order assembly can be moved away with only a slight loss of
efficiency.
The gas fryer is designed for installation on combustible floors
and adjacent to combustible walls. Fryer must be installed
with minimum clearance from all combustible and noncombustible materials, 6 inches from side and 6 inches from back.
2-2 502
Henny Penny Model 500/600
2-2. SELECTING THE
FRYER LOCATION
(Continued)
2-3. LEVELING THE FRYER
The fryer should be installed in such a way as to prevent tipping or
movement causing splashing of hot peanut oil. This may be accomplished by the location of the fryer, or by restraining ties.
The area under the gas and electric fryers is not to be used
as storage. The filter pan sits under the fryer. Supplies
stored under the unit would be ruined and could be a fire
hazard.
For proper operation, the fryer should be level from side to side
and front to back. Place a level on the flat areas around the frypot
collar, then adjust the leveling bolts or casters until the unit is level.
2-4. VENTILATION OF
FRYER
The fryer must be located with provision for venting into adequate
exhaust hood or ventilation system. This is essential to permit efficient
removal of the flue gases and frying odors. Take special precautions
in designing an exhaust canopy to avoid interference with the operation of the fryer. Make certain the exhaust hood is designed high
enough to allow for proper opening of the fryer lid. We recommend
you consult a local ventilation or heating company to help in designing
an adequate system.
Ventilation must conform to local, state, and national codes.
Consult your local fire department or building authorities.
When installing the gas fryer do not attach an extension to
the gas flue exhaust stack. This may impair proper operation of the burner, causing malfunctions and possible
negative back draft.

2-5. GAS SUPPLY
2-6. GAS PIPING
The gas fryer is factory available for either natural or propane gas.
Check the data plate behind the front door of the fryer to determine
the proper gas supply requirements.
DO NOT ATTEMPT TO USE ANY GAS OTHER THAN
THAT SPECIFIED ON THE DATA PLATE. INCORRECT GAS SUPPLY COULD RESULT IN A FIRE OR
EXPLOSION RESULTING IN SEVERE INJURIES AND/
OR PROPERTY DAMAGE.
Please refer below for the recommended hookup of the fryer to main
gas line supply.
To avoid possible serious personal injury:
• Installation must conform with American National Standard
Z223.1 - (the latest edition) National Fuel Gas Code and the
local municipal building codes. In Canada, installation must be
in accordance with Standard CGA Bl49-& 2, Installation Codes
Gas Burning Appliances and local codes.
• The fryer and its individual shut-off valve must be disconnected
from the gas supply piping system during any pressure testing of
that system at test pressures in excess of 1/2 PSIG (3.45 KPA).
• The fryer must be isolated from the gas supply piping system by
closing its individual manual shut-off valve during any pressure
testing of the gas supply piping system at test pressures equal to
or less than 1/2 PSIG (3.45 KPA).
• A standard 3/4 inch, black steel pipe and malleable fittings
should be used for gas service connections.
• Do not use cast iron fittings.
• Although 3/4 inch size pipe is recommended, piping should be
of adequate size and installed to provide a supply of gas sufficient
to meet the maximum demand without undue loss of pressure
between the meter and the fryer. The pressure loss in the piping
system should not exceed 0.3 inch water column.
502 2-5
Henny Penny Model 500/600
2-6. GAS PIPING (Continued)
Provisions should be made for moving the fryer for cleaning and
servicing. This may be accomplished by:
1. Installing a manual gas shut off valve and disconnect union, or
2. Installing a heavy duty design (minimum 3/4 inch) A.G.A. certified
connector which complies with standard connectors for moveable gas appliances. ANSI Z21.69 (the latest edition) or
CAN l, 6. l0M88. Also, a quick disconnect coupling which
complies with the Standard for Quick Disconnect Devices for
use with Gas Fuel, ANSI 21.41 (the latest edition) or CAN 1,
6.9M79. Also, adequate means must be provided to limit the
movement of the fryer without depending on the connector and
any quick-disconnect device or its associated piping to limit the
fryer movement.
3. See the illustration on the following page for the proper connections of the flexible gas line and cable restraint.
The cable restraint limits the distance the fryer can be
pulled from the wall. For cleaning and servicing the fryer,
unsnap the cable from the unit, and disconnect the flexible
gas line. This allows better access to all sides of the fryer.
The gas line and cable restraint must be reconnected once the
cleaning or servicing is complete.
2-7. GAS LEAK TEST
Prior to turning the gas supply on, be sure the gas valve knob
on the gas valve is turned to the OFF position. After the
piping and fittings have been installed, check for gas leaks.
Turn the gas on and brush all connections with a soap solution. Bubbles show escaping gas and that the piping
connection must be redone.
NO OPEN FLAME
NEVER USE A LIGHTED MATCH OR OPEN FLAME
TO TEST FOR GAS LEAKS. ESCAPING GAS COULD
CAUSE AN EXPLOSION, RESULTING IN SEVERE
INJURY AND/OR PROPERTY DAMAGE.

Status Mode
Pressing during idle time, allows Operator to view:
a. The temperature of the peanut oil
b. The temperature setpoint and any offset
c. The average peanut oil temperature during last cook cycle
d. The rate of temperature rise or fall
e. Date and Time
Pressing during a cook cycle allows the Operator to view:
a. The temperature of peanut oil, plus the degrees and rate the Load
Compensation has affected the cook cycle (slows down or speeds
up the timer)
b. The cooking step, the time left in cook cycle, setpoint temperature
and whether pressure is on
c. The average peanut oil temperature in cook cycle so far
d. The rate of temperature rise or fall
e. Date and Time
After 5 seconds, the control exits the Status Mode and the pressure
fryer returns to normal operation.
Peanut Oil Filter Enforcement
Prevents the Operator from exceeding the set number of cook cycles
before filtering the peanut oil. The number in the center of the display
shows how many cook cycles remain before the Filter Lockout occurs.
For example, “5X” means the Operator can run 5 more cook cycles
before filtering. This function cannot be bypassed and greatly increases
the life of the peanut oil.
