2.3 Principles of Operation
The frypot is constructed of welded steel with heat transfer ducting on the frypot-bottom for efficient
heating of oil without scorching.
Base units come equipped with painted cabinetry or optional stainless steel. Base units come
equipped with 6-inch (15-cm) adjustable legs or optional 5-inch (13-cm) casters. Multiple units
come equipped with casters.
Dean 24G Series Flatbottom gas fryers come standard with an electronic thermostat for reliable
temperature control. Fryers can be ordered with boil-out feature (optional- available only with
electronic thermostat controller).
A draft inducer draws air over the burners for combustion. Air movement directs the combustion
products back and forth across the frypot bottom by means of a set of baffles, transferring the heat
evenly across the frypot bottom. Cold air is prevented from entering the combustion chamber and
cooling the oil during the coasting cycle.
2.3.1 Automatic Safety Features
• High oil temperature detection to shut off power to the main burners through the solenoid-
actuated gas valve.
• Combination safety gas valve includes built-in pressure regulator and pilot safety.
• Air prover switch built into outlet duct shuts off gas to the burners in the event of blower
failure.
• Optional safety switch built into the drain valve prohibits burner ignition if the valve is not
completely closed.
2.4 Rating Plate
The rating plate can be found on the inside panel of the fryer door. Information on this plate
includes the model and serial numbers, BTU/hr (kW/hr) of the burners, outlet gas pressure in
BTU/hr (kW/hr), and configuration: natural or propane gas. Rating plate data is essential for proper
unit identification, communicating with the factory or requesting special parts and/or information.
The rating plate is located inside the front door panel. Information provided includes the model and
serial number of the fryer, BTU/hr (kW/hr) of the burners, outlet gas pressure in inches W.C.
(mbars) and whether the unit has natural or propane gas orifices.

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.
1. Keep the area around the fryer clear to prevent obstruction of combustion and ventilation
airflow.
2. Do not connect this fryer to an exhaust duct.
3. Correct installation and adjustment will ensure adequate airflow to the fryer system.
4. 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 500-600°F (260-316°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.
5. 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.
6. Never use the interior of the fryer cabinet for storage or store items on shelving over or
behind the fryer. Exhaust temperatures can exceed 500°F (260°C) and may damage or melt
items stored in or near the fryer.
7. Adequate distance must be maintained from the flue outlet of the fryer(s) to the lower edge
of the exhaust 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.
8. 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.

Note: If a leg becomes damaged during movement, contact your service agent for immediate
repair/replacement.
CAUTION
Fryers may not function properly if curb mounted. Do not curb mount Dean 24G
Series Flatbottom gas fryers.
DANGER
This fryer may tip and cause personal injury if not secured correctly in a stationary
position. Drain all oil/shortening from fryer before moving. Hot oil will splash and
cause severe burns upon contact.
3.2 Leg and Caster Installation
A. General
1. Install legs and rear rigid casters near where the fryer is to be used, as neither is secure for
long transit. Unit cannot be curb mounted and must be equipped with the legs and casters
provided.
2. When positioning the fryer, gently lower the fryer into position to prevent undue strain to
the legs and internal mounting hardware. Use a pallet or lift jack to lift and position the
fryer if possible. Tilting the fryer may damage the legs.
3. The rigid casters must be installed on the fryer rear channel assembly only. Install locking
casters on the front channel assembly.
4. Proceed to Step 3.3, Leveling the Fryer, after legs and rear rigid casters are installed.

3.2 Leg and Caster Installation (cont.)
B. Leg and Rigid Caster Installation
1. Remove unit from pallet.
2. Carefully raise the unit with a forklift, pallet jack, or other steady means. Ensure the weight
is evenly distributed to avoid damaging the channel assemblies.
3. Place one lock washer on each hex head screw.
4. Insert hex head screws with lock washers [1/4-20 threads by ¾" long] through bolt holes of
leg mounting plates and mount to the front channel. Mount rigid casters to the rear channel
following the same procedure. A locknut has been attached to the topside of the base
mounting plates at the factory to capture the hex head screw as it is screwed in.
5. Tighten the bolts to 50 inch-lbs. (5.65 Nm) torque.
CAUTION
For caster retrofit, the unit must be at room temperature and drained of shortening
before installing the casters.
3.3 Leveling the Fryer
A. Place a carpenter’s spirit level across the top of the fryer and level the unit front to back. If the
fryer is not level from side to side, a platform or other surface adjustment is needed; there are no
side-to-side level adjustments on a fryer equipped with caster/leg combinations. (If a fryer is
equipped with legs only, side-to-side level adjustments can be made. If a fryer is equipped with
casters only, no level adjustments to the fryer can be made.) If the fryer is not level, the unit may
not function efficiently, the oil may not drain properly for filtering and in a multi-fryer battery, it
may not match adjacent units.
Legs (Only)
1. Adjust leg height with an adjustable or 1-1/16-inch (27 mm) open-end wrench by turning
the hex bullet on the bottom of the leg.
2. The hex bullet is for minor leg height adjustment only. Do not adjust more than 1-inch
(25.4 mm).
3. When leveling the unit, the leg body should be held firmly to keep the leg from bending or
rotating while turning the hex bullet foot to the required height.
