CHAPTER 2: IMPORTANT INFORMATION
2-2
2.2 General (cont.)
Dean Super Marathon Series gas fryers are energy efficient, gas-fired units, design certified by
(Approvals Pending), and manufactured to their basic performance and application specifications.
All units are shipped completely assembled with accessories packed inside the frypots. All units are
adjusted, tested and inspected at the factory before shipment. Sizes, weights and input rates of all
models are listed in this manual.
WARNING
The on-site supervisor is responsible for ensuring that operators are made aware of
the inherent dangers of operating a hot-oil fryer/filter system, particularly the
aspects of fryer operation, oil filtration, and draining/cleaning procedures.
2.3 Principles of Operation
The incoming gas flows through orifices and is mixed with air in the burners to create the correct
ratio for proper combustion. The mixture is ignited at the front end of each heat tube by the pilot
light. Internal diffusers slow the flame as it goes through the burner tube. This slower and more
turbulent flame gives much better heat transfer to the walls of the tubes, thereby heating the oil more
efficiently.
2.4 Rating Plate
This is attached to the inside front door panel. Information provided includes the model and serial
number of the fryer, BTU/hr input of the burners, outlet gas pressure in inches W.C. and whether the
unit has natural or propane gas orifices.
DANGER
Fryers MUST be connected ONLY to the gas type identified on the attached rating
plate.

2.7 Air Supply and Ventilation
DANGER
This appliance must be installed with sufficient ventilation to prevent the occurrence
of unacceptable concentrations of substances harmful to the health of personnel in
the room in which it is installed.
2.7 Air Supply and Ventilation (cont.)
Keep the area around the fryer clear to prevent obstruction of combustion and ventilation airflow.
1. Do not connect this fryer to an exhaust duct.
2. Correct installation and adjustment will ensure adequate airflow to the fryer system.
3. A commercial, heavy-duty fryer must vent its combustion wastes to the outside of the building.
A deep-fat fryer must be installed under a powered exhaust hood, or an exhaust fan must be
provided in the wall above the unit, as exhaust gas temperatures are approximately 800-1000°F
(427-538°C). Check air movement during installation. Strong exhaust fans in the exhaust hood
or in the overall air conditioning system can produce slight air drafts in the room.
4. Do not place the fryer’s flue outlet directly into the plenum of the hood, as it will affect the gas
combustion of the fryer.
5. Never use the interior of the fryer cabinet for storage or store items on shelving over or behind
the fryer. Exhaust temperatures can exceed 800°F (427ºC) and may damage or melt items stored
in or near the fryer.
6. Adequate distance must be maintained from the flue outlet of the fryer(s) to the lower edge of the
filter bank. Per NFPA Standards No. 96, a minimum of 18-inches (45-cm) should be maintained
between the flue(s) and the lower edge of the exhaust hood filter.
7. Filters and drip troughs should be part of any industrial hood, but consult local codes before
constructing and installing any hood. The duct system, the exhaust hood and the filter bank must
be cleaned on a regular basis and kept free of grease.

3.4 Gas Connections (cont.)
The gas supply (service) line must be the same size or greater than the fryer inlet line. Super
Marathon and Super Runner Series gas fryers are equipped with a 3/4" (22 mm) male ISO 7.1 inlet.
The gas supply line must be sized to accommodate all gas-fired equipment connected to that gas
supply. Consult local gas companies or suppliers, or your local contractor for minimum supply line
requirements.
Supply Line Specifications
The gas supply lines must be sized as indicated in the chart below, based on the total number of
fryers connected to the main gas supply.
Recommended Gas Supply Line Sizes
Gas Types Number of Fryers
1 2 to 3 4 or more (*)
Natural Gas 3/4" (22 mm) 1" (28 mm) 1-1/4" (35 mm)
Propane Gas 1/2" (15 mm) 3/4" (22 mm) 1" (28 mm)
(*) When exceeding 18 feet (6 meters) for a configuration of more than four fryers, it is necessary
to provide a 1 1/4" (35 mm) rigid gas connection.
DANGER
All connections must be sealed with a joint compound suitable for the gas being
used and all connections must be tested with a solution of soapy water before
lighting any pilots.
Never use matches, candles, or any other ignition source to check for leaks. If gas
odors are detected, shut off the gas supply to the appliance at the main shut-off
valve and immediately contact the local gas company or an authorized service

DEAN MILLIVOLT GAS FRYERS (NON-CE)
CHAPTER 3: INSTALLATION INSTRUCTIONS
3-6
3.4 Gas Connections (cont.)
Rigid Connections
Check any installer-supplied intake pipe(s) visually and clean metal particles or other foreign matter
from the threads before installing into a service line. If the intake pipes are not clear of all foreign
matter, the orifices will clog when gas pressure is applied. When using thread compound on gas
piping, use very small amounts and only on male threads. Use a pipe thread compound that is not
affected by the chemical action of LP gases. DO NOT apply thread compound to the first two pipe
threads – doing so will cause clogging of the burner orifices and control valve.
Manual shut-off valve
This gas service supplier-installed valve must be installed in the gas service line ahead of the fryers
in the gas stream and in a position where it can be reached quickly in the event of an emergency.
Regulating Gas Pressure
The fryer and shut-off valve must be disconnected from the gas supply during any pressure testing of
the system.
External gas regulators are not normally required on this fryer. A safety control valve protects the
fryer against pressure fluctuations. If the incoming pressure is in excess of ½" PSI (3.45 kPa/35
mbar), a step-down regulator will be required.
DANGER
When pressure-testing incoming gas supply lines, disconnect the fryer from the gas
line if the test pressure is ½" PSI [3.45 kPa (14 inches W.C.)] or greater to avoid
damage to the fryer’s gas piping and gas valve(s).
A. Manifold Pressure: Your local service technician should check the manifold pressure with a
manometer.
1. Check the rating plate for manifold gas pressures. Natural gas units normally require 4-
inches W.C., and propane units normally require 11-inches W.C. gas pressure.
2. Confirm that the arrow forged into the bottom of the regulator body, which indicates gas
flow direction, is pointed downstream towards the fryers. The air vent cap is also part
of the regulator and should not be removed.
3. If a vent line from the gas pressure regulator is used, it should be installed in accordance
with local codes or in the absence of local codes, with the appropriate national
standards.

3.4 Gas Connections (cont.)
WARNING
Use a diluted soap solution to find potentially dangerous gas leaks when making
new connections.
B. Regulators: Gas regulators can be adjusted in the field, but no adjustments should be made
unless the regulator is out of adjustment, or serious pressure fluctuations are observed.
C. Only qualified service personnel should make adjustments to the regulators.
D. Orifices: The fryer can be configured to operate on any available gas. The correct safety
control valve, appropriate gas orifices, and pilot burner are installed at the factory. While
the valve can be adjusted in the field, only qualified service personnel should make any
adjustments with the proper test equipment.
E. Flexible Couplings, Connectors and Casters
1. If the fryer is to be installed with flexible couplings and/or quick-disconnect fittings, the
installer must use a heavy-duty certified commercial flexible connector of at least 3/4"
(22 mm) NPT (with suitable strain-relief attachments), in compliance with local codes or
in the absence of local codes, with the appropriate national standards. Quick-disconnect
devices must comply with local codes or in the absence of local codes, with the
appropriate national standards.
2. For an appliance equipped with casters, the installation shall be made with a connector
that complies with local codes or in the absence of local codes, with the appropriate
national standards.
3. Under no circumstances are the connector and the quick-disconnect device, or its
associated piping to be used to limit fryer movement. A restraining bracket is provided on
the appliance back to prevent the unit from moving from its installed position.
WARNING
Do not attach accessories to this fryer unless fryer is secured from tipping.
Personal injury may result.
4. To limit movement of the fryer, restraints independent of the flexible coupling or

3.9 Electrical Connections
Fryers without built-in filtration do not require electrical connection. Fryer systems with built-in
filtration when installed must be electrically grounded in accordance with local codes, or in the
absence of local codes, with the appropriate national standards.
WARNING
Fryers with built-in filtration systems are equipped with a three-prong (grounding)
plug for protection against shock hazard. It should be plugged directly into a
properly grounded, three-prong receptacle. DO NOT CUT, REMOVE, OR
OTHERWISE BYPASS THE GROUNDING PRONG ON THIS PLUG.
For fryers with built-in filtration systems: The rating plate and wiring diagram are located on the
inside front door panel. Built-in filtration systems are equipped with 120VAC single-phase 60-hertz
system (Domestic), or 230VAC single-phase 50-hertz system (International/CE). Do not cut or
remove the ground prong from the power cord plug.
DANGER
This appliance requires electrical power (built-in filtration systems only) for
operation. Place the gas control valve in the OFF position in case of a prolonged

4.1 Initial Start-up
WARNING
The on-site supervisor is responsible for ensuring that operators are made aware of
the inherent hazards of operating a hot oil frying system, particularly the aspects of
system operation, oil filtration, draining and cleaning procedures.
Cleaning: New units are wiped clean with solvents at the factory to remove any visible signs of dirt,
oil, grease, etc. remaining from the manufacturing process, then coated lightly with oil. Before any
food preparation, wash thoroughly with hot, soapy water to remove any film residue and dust or
debris then rinse out and wipe dry. Also wash any accessories shipped with the unit. Close the drain
valve completely and remove the crumb screen covering the heating tubes. Ensure the screws
holding the thermostat and high-limit control sensing bulbs into the frypot are tight.
WARNING
Do not bang fry baskets or other utensils on the fryer’s joiner strip. The strip is
present to seal the joint between the frypot. Banging fry baskets on the strip to
dislodge shortening will distort the strip, adversely affecting its fit. It is designed for
a tight fit and should only be removed for cleaning.
DANGER
Never operate this appliance with an empty frypot. The frypot must be filled with
water or cooking oil/shortening before lighting the burners. Failure to do so will
damage the frypot and may cause a fire.
WARNING
When checking for burner ignition or performance, do not get too close to the
burners. Slow ignition can cause possible flashback, increasing the potential for
facial and body burns.

4.1.1 Pilot Lighting Procedures, Standing Pilot Only
Initial Pilot Lighting: All Dean fryers are tested, adjusted and calibrated to sea level conditions
before leaving the factory. Adjustments to assure proper operation of pilot may be necessary on
installation to meet local conditions, low gas pressure, differences in altitude and variations in gas
characteristics. These adjustments correct possible problems caused by rough handling or vibration
during shipment, and are to be performed only by qualified service personnel. These adjustments
are the responsibility of the customer and/or the dealer and are not covered by the Dean warranty.
The inlet pipe at the lower rear of the fryer brings incoming gas to the pilot safety control valve, then
to the pilot and main burners. The pilot is located high in the cabinet center, at the base of the
frypot.
Light the pilot as follows:
1. Turn off the manual shut-off valve on the incoming service line.
2. Turn the operating thermostat off.
3. Depress the pilot gas cock dial on the combination control valve and turn to "OFF".
4. Wait approximately 5 minutes for accumulated gas to disperse.
Note: Inspect high-limit thermostat/temperature probe location prior to filling
frypot with water or oil. Ensure that connecting hardware is intact and bulbs are
properly attached.
5. Fill the frypot with oil or water to the bottom OIL LEVEL line scribed on the frypot back.
Ensure that heating tubes are covered in liquid prior to engaging burners.
6. Open the manual shut-off valve on the incoming service line.
7. Apply lighted match or taper to the pilot burner head.
8. Turn the gas cock dial on the control valve to "Pilot", then depress and hold the dial until
the pilot stays lit (approximately 1 minute).
9. If the pilot fails to stay lit, depress the dial and re-light the pilot, depressing the dial
longer before releasing.
10. When the pilot stays lit, turn the gas cock dial to "ON".
11. Turn the operating thermostat on, then ensure the main burners ignite from the pilot.

4.2 Boil-Out Procedure
DANGER
Never leave the fryer unattended during the boil-out process. If the boil-out solution
boils over, turn the fryer off immediately and let the solution cool for a few minutes
before resuming the process. To lessen the chance of boil over, turn the fryer’s gas
valve knob to the PILOT position occasionally.
WARNING
Do not drain boil-out solution into a shortening disposal unit, a built-in filtration unit,
or a portable filter unit. These units are not intended for this purpose, and will be
damaged by the solution.
DANGER
Remove all drops of water from the frypot before filling with cooking oil or
shortening. Failure to do so will cause spattering of hot liquid when the oil or
shortening is heated to cooking temperature and may cause injury to nearby
personnel.
4.2.1 Thermostat-Equipped Fryers
A. Pour cleaning solution into the frypot and add water to the bottom OIL LEVEL line scribed
in the back of the frypot.
B. Set the operating thermostat dial/temperature controller to 225°F (107ºC), just above that of
boiling water.
C. The main burner will ignite.
D. When the solution nears boiling point, reset the temperature controller to 200°(93ºC).
E. The burners should shut off just as the water starts to boil.
F. The burners will heat the boil-out solution to a simmer. Simmer the solution for
approximately 45 minutes. Wearing protective gloves, scrub the sides of the frypot and the
tubes with the L-shaped Teflon brush, being careful not to disturb the temperature sensing
probes and the high-limit thermostat.
G. Do not allow the water level to decrease below the bottom OIL LEVEL line in frypot during
boil-out operation.

4.2.1 Thermostat-Equipped Fryers (cont.)
WARNING
Water or boil-out solution MUST not be allowed to drain into the filter pan or filter
system. Irreversible damage will result if water is allowed into the system.
H. After boil out is complete, turn the thermostat dial to "OFF" and drain the solution from the
frypot. Place a metal stockpot of sufficient size to safely hold the entire contents of the
frypot under the drain port to collect the water/boil-out solution. Do not allow water or boil-
out solution to drain into the filter pan. The filter pump is not designed for water operation,
and will be irreparably damaged (see warning statement above).
I. Close the drain, add fresh water (without boil-out solution) and wash all surfaces of the
frypot. Drain again.
J. Refill the frypot with fresh water and vinegar to neutralize any residual boil-out solution.
Wash all surfaces of the frypot. Drain completely and wipe down all surfaces of the frypot
to completely remove all water.
NOTE: It is recommended that the boil-out procedure be performed each time the oil/shortening is
changed.
DANGER
Do not go near the area directly over the flue outlet while the fryer is operating.
Always wear oil-proof, insulated gloves when working with the fryer filled with hot
oil.
Always drain hot oil into a metal stockpot of sufficient size to safely hold the entire
contents of the frypot.
4.3 Final Preparation
WARNING
NEVER set a complete block of solid shortening on top of heating tubes. To do so
will damage the heating tubes and frypot, and void the warranty.
4.3.1 Filling Fryer with Cooking Oil/Shortening—Operating Thermostat

4.3.1 Filling Fryer with Cooking Oil/Shortening—Operating Thermostat (cont.)
B. When using a solid shortening, first melt it in a suitable container, or cut it into small pieces
and pack it below the heat tubes, between the tubes and on top of the tubes, leaving no air
spaces around the tubes. Do not disturb or bend the sensing bulbs.
C. If the shortening is not pre-melted and is packed around the tubes, turn the burners "ON" for
about 10 seconds, "OFF" for a minute, etc., until the shortening is melted. If you see smoke
coming from the shortening while melting this way, shorten the "ON" cycle and lengthen
the "OFF" cycle. Smoke indicates potential scorching of the shortening, which will shorten
its useful life.
D. Before starting operation, turn the operating thermostat to the probable working
temperature; wait for the temperature to stabilize then check with a high-quality immersion
thermometer.
For filtration instructions and troubleshooting, consult the operating manual or
instructions provided with the filtration equipment.

filled with hot oil/shortening. If water comes in contact with oil/shortening heated to
cooking temperature, it will cause spattering of the oil/shortening, which can result
in severe burns to nearby personnel.
Any equipment works better and lasts longer when maintained properly and kept clean. Cooking
equipment is no exception. Dean millivolt gas fryers should be kept clean during the working day
and thoroughly cleaned at the end of each day. Below are recommendations for daily, weekly and
periodic preventative maintenance.
5.1.1 Daily
WARNING
Use a commercial grade cleaner formulated to effectively clean and sanitize food-
contact surfaces. Read the directions for use and precautionary statements before
use. Particular attention must be paid to the concentration of cleaner and the length
of time the cleaner remains on the food-contact surfaces.
A. Remove and wash all removable parts.
B. Clean all exterior surfaces of the cabinet. Do not use cleaners, steel wool, or any other
abrasive material on stainless steel.
C. Filter the cooking oil and replace if necessary. The oil should be filtered more frequently
when under heavy use.
5.1.2 Weekly
A. Completely drain the oil from the fryer into a metal stockpot of sufficient size to safely hold
the entire contents of the frypot for disposal. Do not use a glass or plastic container.
B. Clean the frypot by following boil-out procedures in Chapter 4-2.
WARNING
Never allow water to boil down and expose the heating tubes. Frypot damage will
result.

of a regular kitchen maintenance program.
Dean recommends that the fryer be inspected at least annually by a Factory Authorized
Service Technician as follows:
Inspect fryer cabinet inside and out, front and rear, for excessive oil build-up and/or oil
migration. Verify that burners and associated components (i.e. gas valves, pilot assemblies,
ignitors, etc.) are in good condition and functioning properly. Inspect all gas connections for
leaks and ensure all connections are properly tightened.
Verify that temperature and high-limit probes are properly connected, tightened and functioning
properly.
Verify that all electronic components (i.e. computer/controller, relays, transformers, interface
boards, etc.) are in good condition and free from oil migration build-up and other debris. Inspect
any wiring and ensure all connections are tight and all wiring is in good condition. Ensure all
safety features (i.e. drain safety switches, reset switches, etc.) are present and functioning
properly.
Verify that frypot is in good condition and free of leaks. Verify that frypot tube diffusers are
present and in good condition (i.e. no visible deterioration or damage).
Verify that all wiring and connections are tight and in good condition.
See filtration manual for filtration maintenance procedures.
5.1.4 Stainless Steel Care
DANGER
DO NOT let water splash into the tank of hot oil. It will splatter and can cause severe
burns.
