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.

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
