2-1
J1C, J1X, & J2X MASTER JET SERIES GAS FRYERS
CHAPTER 2: INSTALLATION INSTRUCTIONS
2.1 General Installation Requirements (cont.)
CLEARANCE AND VENTILATION
DANGER
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.
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.
The fryer(s) must be installed with a 6" (150 mm) clearance at both sides and back when installed
adjacent to combustible construction; no clearance is required when installed adjacent to
noncombustible construction. A minimum of 24" (600 mm) clearance should be provided at the
front of the fryer.
An important consideration of efficient fryer operation is ventilation. Ensure the fryer is installed so
flue gas is removed efficiently and the kitchen ventilation system does not produce drafts that
interfere with proper burner operation.
The fryer flue opening must not be placed close to the intake of the exhaust fan, and the fryer must
never have its flue extended in a "chimney" fashion. An extended flue changes the combustion
characteristics of the fryer, causing longer recovery time. It also frequently causes delayed ignition.
To provide the airflow necessary for good combustion and burner operation, the areas surrounding
the fryer front, sides, and rear must be kept clear and unobstructed.
Fryers must be installed in an area with an adequate air supply and adequate ventilation. Adequate
distances must be maintained from the flue outlet of the fryer to the lower edge of the ventilation
filter bank. Filters should be installed at an angle of 45 degrees. Place a drip tray beneath the lowest
edge of the filter. For U.S. installation, NFPA standard No. 96 states, "A minimum distance of 18
inches (450 mm) should be maintained between the flue outlet and the lower edge of the grease
filter." Frymaster recommends that the minimum distance be 24 inches (600 mm) from the flue
outlet to the bottom edge of the filter when the appliance consumes more than 120,000 BTU per
hour.
Information on construction and installation of ventilating hoods can be found in the NFPA standard
cited above. A copy of the standard may be obtained from the National Fire Protection Association,
Battery March Park, Quincy, MA 02269.

J1C, J1X, & J2X MASTER JET SERIES GAS FRYERS
CHAPTER 2: INSTALLATION INSTRUCTIONS
2.1 General Installation Requirements (cont.)
NATIONAL CODE REQUIREMENTS
The type of gas for which the fryer is equipped is stamped on the data plate attached to the inside of
the fryer door. Connect a fryer stamped "NAT" only to natural gas, those stamped "PRO" only to
propane gas, and those stamped "MFG" only to manufactured gas.
Installation shall be made with a gas connector that complies with national and local codes. QuickDisconnect devices, if used, shall likewise comply with national and local codes.
2.2 Leg Installation
DANGER
DO NOT install this appliance without legs.
Depending upon the specific configuration ordered, the fryer might have been shipped without
installed legs. If legs are installed, you may skip this section and proceed to Section 2.3, PreConnection Preparations.
If your fryer requires the installation of legs, install them in accordance with the instructions
included in your accessory package.
2.3 Pre-Connection Preparations
DANGER
Do not connect this appliance to the gas supply before completing each step in this
section.
DANGER
Do not attach an apron drain board to a single fryer. The fryer may become
unstable, tip over, and cause injury. The appliance area must be kept free and clear
of combustible materials at all times.
After the fryer has been positioned under the fry station exhaust hood, ensure the following has been
accomplished:
1. Level fryers equipped with legs by screwing out the legs approximately 1 inch, and then
adjust them so that the fryer is level and at the proper height in the exhaust hood. Frymaster
recommends that the minimum distance from the flue outlet to the bottom edge of the filter
be 24 inches (600 mm) when the appliance consumes more than 120,000 BTU per hour.

2.4 Connection to Gas Line
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.
DANGER
When pressure-testing incoming gas supply lines, disconnect the fryer from the gas
line if the test pressure will be ½ PSIG (3.45 kPa, 13.84 inches W.C.) or greater to
avoid damage to the fryer’s gas tubes and gas valve(s).
2-4
J1C, J1X, & J2X MASTER JET SERIES GAS FRYERS
CHAPTER 2: INSTALLATION INSTRUCTIONS
The size of the gas line used for installation is very
important. If the line is too small, the gas pressure at
the burner manifold will be low. This may cause
slow recovery and delayed ignition. The incoming
gas supply line should be a minimum of ½" (13 mm)
in diameter. Refer to the chart below for the
minimum sizes of connection piping.

1. Connect the quick-disconnect hose to the fryer quick-disconnect fitting under the front of the
fryer and to the building gas line.
NOTE: Some fryers are configured for a rigid connection to the gas supply line. These units are
connected to the gas supply line at the rear of the unit.
When using thread compound, use very small amounts on male threads only. Use a pipe thread
compound that is not affected by the chemical action of LP gases (Loctite PST567 sealant is one
such compound). DO NOT apply compound to the first two threads. Applying compound to the
first two threads will cause clogging of the burner orifices and control valve.
2. Open the gas-supply valve to the fryer and check all piping, fittings, and gas connections for
leaks. A soap and water solution should be used for this purpose.
2-5
J1C, J1X, & J2X MASTER JET SERIES GAS FRYERS
CHAPTER 2: INSTALLATION INSTRUCTIONS
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.
3. Close the fryer drain valve and fill the frypot with water and boil-out solution to the bottom OILLEVEL line at the rear of the frypot. Light the fryer and perform the boil-out procedures that are
described in the "Lighting Instructions" and "Boiling Out the Frypot" topics found in Chapter 3
of this manual.
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 your

CHAPTER 3: OPERATING INSTRUCTIONS
MELT CYCLE
CAUTION
If this is the first time the fryer is being used after installation, refer to Section 3.2,
Boiling-Out the Frypot.
Complete the following steps:
1. Make sure the fryer gas valve is in the OFF or PILOT position.
2. Close the frypot drain valve. Remove the basket support rack, if required.
3. Fill the frypot to the OIL-LEVEL line. When solid shortening is used, make sure it is packed
down into the frypot cold zone.
4. To melt solid shortening without scorching, alternately turn the burner ON for 3 seconds and
OFF for about 10 seconds until the shortening is melted. If smoke is seen during this process,
the shortening is being heated too quickly and scorching. This step is not necessary if using
liquid oil.
CAUTION
Thermostat-controlled fryers equipped with Melt Cycle switches will stay in the Melt
Cycle mode until the Melt Cycle switch is placed in the OFF position.
3.2 Boiling-Out the Frypot
To ensure that the frypot is free of any contamination resulting from its manufacture, shipping, and
handling during installation, the frypot must be boiled out before first use. Frymaster recommends
boiling out the frypot each time the oil or shortening is changed.
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.
1. Before lighting the burner, close the fryer drain valve(s) and fill the frypot to the bottom OILLEVEL line with a mixture of cold water and automatic dishwashing detergent.
2. Set the thermostat to the lowest setting. Turn the fryer on as described in Section 3.1 (Lighting
the Pilot). Allow the solution to come to a boil, and then turn the gas valve knob to PILOT.
Allow the solution to set for 30 minutes. Turn the gas valve knob to ON and allow the solution
to come to a boil. Turn gas valve knob to PILOT and allow solution to set for 30 minutes.

CHAPTER 4: FILTRATION INSTRUCTIONS
4. Filtration
WARNING
The on-site supervisor is responsible for ensuring that operators are made aware of
the inherent hazards of operating a hot oil filtering system, particularly the aspects
of oil filtration, draining and cleaning procedures.
DANGER
Draining and filtering of cooking oil or shortening must be accomplished with care to
avoid the possibility of a serious burn caused by careless handling. The oil to be
filtered is at or near 350°F (177°C). Ensure all hoses are connected properly and
drain handles are in their proper position before operating any switches or valves.
Wear all appropriate safety equipment when draining and filtering cooking oil or
shortening.
DANGER
NEVER attempt to drain cooking oil or shortening from the fryer with the burner lit!
Doing so will result in a flash fire if the oil or shortening splashes onto the burner.
Applying burner heat to an empty frypot will severely damage the frypot and void
warranties.
DANGER
Allow oil or shortening to cool to 100°F (38°C) or lower before draining to an
appropriate container for disposal.
DANGER
When draining oil/shortening into a disposal unit or portable filter unit, do not fill
above the maximum fill line located on the container.
The cooking oil or shortening must be drained into another suitable container. For safe, convenient
draining and disposal of used cooking oil or shortening, Frymaster L.L.C. recommends the use of the
Frymaster shortening disposal unit (SDU). The SDU is available through your local distributor.
1. Turn the fryer gas valve knob to PILOT. Screw the drainpipe (provided with your fryer) into the
drain valve. Make sure the drainpipe is firmly screwed into the drain valve and that the opening
of the curved end is pointing down.
4-1
J1C, J1X, & J2X MASTER JET SERIES GAS FRYERS
CHAPTER 4: FILTRATION INSTRUCTIONS
4. Filtration (cont.)
2. Position a metal container with a sealable cover under the drainpipe. The metal container must
be able to withstand the heat of the cooking oil or shortening, and hold hot liquids. If you intend
to reuse the oil or shortening, use a Frymaster filter cone holder and filter cone when a filter
machine is not available. If you are using a Frymaster filter cone holder, be sure that the cone
holder rests securely on the metal container.
3. Open the drain valve slowly to avoid splattering. If the drain valve becomes clogged with food
particles, use the Fryer’s Friend (poker-like tool) to clear the blockage.
DANGER
DO NOT insert anything into the drain from the front to unclog the valve. Hot
oil/shortening will rush out, creating an extreme hazard.
WARNING
DO NOT hammer on the drain valve with the Fryer’s Friend. This will damage the
drain valve ball and prevent the valve from sealing securely, resulting in a leaky
valve.
4. After draining the oil or shortening, clean all food particles and residual oil or shortening from
the frypot. Use caution as frypot residue can cause severe burns if it contacts bare skin.
5. Close the drain valve securely and fill the frypot with clean, filtered or fresh cooking oil or solid
shortening to the bottom OIL-LEVEL line.
DANGER
When using solid shortening, pack it down into the cool-zone and the bottom of the
frypot. DO NOT operate the fryer with a block of shortening sitting in the upper
portion of the frypot. Irreparable damage to the frypot and a potential flash fire will
result.

Inspect Fryer and Accessories for Damage
Look for loose or frayed wires and cords, leaks, foreign material in frypot or inside cabinet, and any
other indications that the fryer and accessories are not ready and safe for operation.
Inspect the burner targets. Ensure the targets are in position above each orifice, and that the flame
ignites approximately 2-½ inches (60 mm) above the orifice. The flame should strike the center of
the target and be a rich blue color. Call your factory authorized servicer (FAS) if you see any
problems.
Clean Fryer Cabinet Inside and Out
DANGER
Never attempt to clean the fryer during the cooking process or when the frypot is
filled with hot oil. If water comes in contact with oil heated to cooking temperature, it
can cause spattering, which can result in severe burns to nearby personnel.
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.
Clean inside the fryer cabinet with dry, clean cloth. Wipe all accessible metal surfaces and
components to remove accumulations of oil and dust.
Clean the outside of the fryer cabinet with a clean, damp cloth soaked with dishwashing detergent,
removing oil, dust, and lint from the fryer cabinet.
Filter Cooking Oil
The cooking oil used in your fryer should be filtered at least once every day (more often if the fryer
is in constant use). Refer to Chapter 4, Filtration Instructions, for details.
