DANGER
Adequate means must be provided to limit the movement of this appliance without depending
upon the gas line connection. Single fryers equipped with legs must be stabilized by installing
anchor straps. All fryers equipped with casters must be stabilized by installing restraining
chains. If a flexible gas line is used, an additional restraining cable must be connected at all
times when the fryer is in use.
DANGER
The front ledge of the fryer is not a step. Do not stand on the fryer. Serious injury can result
from slips or contact with the hot oil.
DANGER
Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any
other appliance.
DANGER
Instructions to be followed in the event the operator smells gas or otherwise detects a gas leak
must be posted in a prominent location. This information can be obtained from the local gas
company or gas supplier.
DANGER
The crumb tray in fryers equipped with a filter system must be emptied into a fireproof container
at the end of frying operations each day. Some food particles can spontaneously combust if left
soaking in certain shortening material. Additional information can be obtained in the filtration
manual included with the system.
WARNING
No structural material on the fryer should be altered or removed to accommodate placement of
the fryer under a hood. Questions? Call the Frymaster/Dean Service Hotline at 1-800-551-8633.
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.

3.1 Installing the Fryer
A. Initial Installation: If the fryer is installed with legs, do not push the fryer to adjust its
position. Use a pallet or lift jack to lift the fryer slightly, then place the fryer where it is to be
installed.
B. Relocating the fryer: Remove all weight from each leg before moving a fryer with legs
installed. Do not slide the fryer on the legs.
C. If a leg becomes damaged, contact your service agent for immediate repair/replacement.
3.2 Leveling the Fryer (Fryers equipped with legs only)
A. All Installations: If the floor is uneven or has a definite slope, place the fryer on a level
platform.
B. Place a spirit level across the top of the fryer and level the unit both front-to-back and side-
to-side. If it is not level, the unit may not function efficiently, the oil may not drain properly
for filtering and in a line-up it may not match adjacent units.
C. Adjust to the high corner and measure with the spirit level. If floor is uneven, level the unit
with the screw adjustments on each leg (ensure minimum clearances as discussed in
Chapter 2 are maintained during the leveling procedure).
D. Re-leveling: If the fryer is moved, re-level the fryer following the above instructions.
E. The install must be reviewed at the time of installation to ensure it meets the intent of these
instructions.

3.4 Gas Connections
DANGER
Before connecting new pipe to this appliance the pipe must be blown out thoroughly
to remove all foreign material. Foreign material in the burner and gas controls will
cause improper and dangerous operation.
NATIONAL CODE REQUIREMENTS
This equipment is to be installed in compliance with the Basic Plumbing Code of the Building
Officials and Code Administrators International, Inc. (BOCA) and the Food Service Sanitation
Manual of the U.S. Food and Drug Administration.
This equipment is manufactured to use the type of gas specified on the rating plate attached to the
door. Connect equipment stamped "NAT" only to natural gas and that stamped "PRO" only to LP
(Propane) gas.
Installation shall be made with a gas connector that complies with national and local codes.
Quick disconnect devices, if used, shall likewise comply with national and local codes.
DANGER
The fryer MUST
MUSTMUST
MUST be connected to the gas supply specified on the rating and serial number
plate located on the back of the fryer door.
DANGER
If gas odors are detected, the gas supply MUST
MUSTMUST
MUST be shut off at the main shut-off valve. The
local gas company or FASC should be contacted immediately to rectify the problem.
A. The gas supply (service) line must be the same size or greater than the fryer inlet line. This
fryer is equipped with a 3/4" (22 mm) male inlet. The gas supply line must be sized to
accommodate all the gas-fired equipment that may be connected to that gas supply. Consult
your contractor, gas company, supplier, or other knowledgeable authorities.
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)

3.4 Gas Connections (cont.)
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
agency for service.
DANGER
"Dry-firing" your unit will cause damage to the frypot and can cause a fire. Always
ensure that melted shortening, cooking oil or water is in the frypot before firing the
unit.
B. Rigid Connections: Check any installer-supplied intake pipe(s) visually and clean threading
chips, or any other foreign matter 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. Seal pipe
joints with a sealant resistive to LP gas. 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.
C. 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.
D. Regulating Gas Pressure: The fryer and shut-off valve must be disconnected from the gas
supply during any pressure testing of the system.
1. 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).
