Henny Penny fryers have many safety features incorporated. However, the only way
to ensure safe operation is to fully understand the proper installation, operation, and
maintenance procedures. The instructions in this manual have been prepared to aid
you in learning the proper procedures. Where information is of particular importance
or is safety related, the words DANGER, WARNING, CAUTION, or NOTICE are used.
Their usage is described as follows:
DDAANNGGEERR!! indicates hazardous situation which, if not
avoided, will result in death or serious injury.
DDAANNGGEERR!!
WWAARRNNIINNGG!! indicates hazardous situation which, if not
avoided, could result in death or serious injury.
WWAARRNNIINNGG!!
CCAAUUTTIIOONN!! indicates hazardous situation which, if not
avoided, could result in moderate or minor injury.

NOTICE
NOTICE is used for information considered important
regarding property damage.

Preface

These are the original version controlled Henny Penny instructions for Evolution Elite
Gas (EEG) model 252, 253 or 254 (EEG-252/253/254). This manual is available on
the Henny Penny Public website (www.hennypenny.com). Read these instructions
completely prior to installation and operation of this appliance to ensure compliance to
all required installation, operation and safety standards. Read and obey all safety
messages to avoid damage to the appliance and personal injury.

This appliance is intended for commercial use in kitchens of restaurants, bakeries,
hospitals, etc. but not for the continuous mass production of food such as in a factory
setting. During use the units airborne A-weighted emission sound pressure is below
70 db(A). All repairs must be performed by the manufacturer, its service agent or
similarly qualified persons in order to avoid a hazard.
Always use strain relief. The provided power cord must be installed with a strain relief
in a way that if the strain relief fails, wires L1, L2, L3 and N must draw taunt and fail
first. If the supplied power cord or an existing one becomes damaged, do not use it;
rather, replace it with a known good power cord. The power cord must be replaced by
the manufacturer, its service agent or similarly qualified persons in order to avoid a
hazard.
Proper daily, weekly, monthly, quarterly and yearly maintenance must be performed
on this appliance to ensure safe and continuous operation. This appliance must never
be cleaned with a water jet or steam cleaning tool. Cleaning brushes are shipped with
the appliance and proper cleaning instructions are included in this manual.
Proper maintenance also increases the usable life of the appliance and oil, which
reduces lifetime operating costs. Additionally, old oil increases the possibility of surge
boiling and fire due to the reduced flash point of the oil. The oil temperature must
never exceed 450⁰ F (230⁰ C).
This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge, unless
they have been given supervision or instruction concerning use of the appliance by a

Preface
vii
person responsible for their safety. Children should be supervised to ensure that they
do not play with the appliance.
This appliance is not intended to be operated by means of an external timer or a
separate remote control system.
This appliance must be installed with suitable ventilation in accordance with the
manufacturer’s instructions and the regulations in force to prevent the occurrence of
unacceptable concentrations of substances harmful to health. Proper air flow is
essential to permit efficient removal of the steam exhaust and frying odors.
For gas appliance installations in South Africa, the installation shall be carried out by a
registered installer, and the installation shall comply with requirements of SANS
10087-1 or SANS827 as applicable.

Preface

Gas supply tubing or hose must comply with the national requirements in force and be
periodically examined and replaced as necessary. Use an approved flexible hose with
a length that does not exceed 1.5 m. Also follow these guidelines:

This section provides troubleshooting information in the form of an easy to read table.
If a problem occurs during the first operation of a new fryer, recheck the installation
per the Installation section of the Operator’s Manual. Before troubleshooting, always
recheck the Operating section of the Operator’s Manual.
11..22 TTrroouubblleesshhoooottiinngg
To isolate a malfunction, proceed as follows:
11)) Clearly define the problem (or symptoms) and when it occurs.
22)) Locate the problem in Table 1-1 Troubleshooting , page 1.
33)) Review all possible causes. Then, one-at-a-time work through the list of
corrections until the problem is solved.
44)) Refer to the maintenance procedures in Chapter 6 Maintenance , page 37 to
safely and properly make the checkout and repair needed.
