b. InsTallaTIon
b.1 Pre-Installation
Uncrate the broiler and inspect for shipping damage. Remove the tape securing the machine parts, and
install the parts in their proper location. If there are obvious or concealed damages to any part of the
broiler, please contact your freight carrier. The factory warranty does not cover freight damage.
b.2 Mounting
Follow the mounting instructions if this function is not performed by the installer.
b.3 leveling
The grease drain system is based on a gravity-flow design. Therefore, it is extremely important that the
broiler be placed on a level surface.
b.4 Hood Requirements
This appliance must be installed under a ventilation hood of adequate size. Do not obstruct the flow of
combustion and ventilation air. An adequate air supply must be available for safe and proper operation.
For installations in the Commonwealth of Massachusetts the following shall apply: Venting shall be in
compliance with NFPA Section 10.3.5.2 for the Model JF93.
b.5 Clearance
Keep appliance area free from combustibles.
To facilitate disassembly and service of the unit a minimum of 24” (610 mm) should be allowed on the
control panel (feed end) of the broiler.

b.6 Gas Connection- 3/4” n.P.T.
At rated input the gas supply should deliver a minimum pressure of at least 15 mbar (6" water column)
at the broiler connection for natural gas. Incoming gas supply pressure must not exceed 50 mbar (14"
water column).
note: The installation of this appliance must conform with local codes, or in the absence of local codes,
with the National Fuel Gas Code, ANSI Z223.1, Natural Gas Installation Code, CAN/CGA-B149.1
including:
1. The appliance and its individual shutoff valve must be disconnected from the gas supply
piping system during any pressure testing of that system at test pressures in excess of
1/2 psi (3.45 kPa).
2. The appliance must be isolated from the gas supply piping system by closing its
individual manual shutoff valve during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2 psi (3.45 kPa).
By public initiative, the State of California has adopted legislation (Proposition 65) which requires
manufacturers of many types of products, including gas appliances, to warn consumers of their
products that contain chemicals or produce substances listed by the State of California to either
cause cancer, birth defects or other reproductive harm.
WaRnInG
If not installed, operated and maintained in accordance with the manufacturers instructions, this
product could expose you to substances in fuel or from fuel combustion which can cause cancer,
birth defects or other reproductive harm.
b.7 Installing Gas appliance Connectors and flexible Gas lines Correctly
For safety in the kitchen area, and to insure maximum service life, it is vitally important to correctly install
connectors. The connector shall comply with the Standard for Connectors for Moveable Gas Appliances,
ANSI Z21.69 or CAN/CGA-6.16 and a quick disconnect device that complies with the Standard for QuickDisconnect Devices for use with gas fuel, ANSI Z21.41 or CAN1-6.9
In order to avoid sharp kinks or excessive bends that could have a damaging effect on the connector, it
may be necessary to attach pipe elbows in order to bring the connector into its proper plane. For easy
movement of the appliance, the connector should be installed with a "lazy" loop for minimum tension.
note: Gas appliances should be disconnected prior to maximum movement. (Minimal movement
is possible to connect hose.)

Nieco Corporation - Model JF93G
b.8 Restraining Device Installation and Use
This high strength restrainer is to be used with all moveable (castered) appliances. It fully complies with
American Gas Association requirements. References: Z21.69, Z83.11, and Z21.41 with current revisions.
Installation is quick and positive. In Canada, device is in accordance with CAN 1-6.9-M70 Quick
Disconnect Devices for use with gas fuel, and CAN 1-6.10-88 metal connectors for gas appliances.
Correct length for any appliance is simply a matter of loosening two adjuster clips (1) and re-tightening.
(3" to 6" shorter than appliance connector is desired length.) Restrainer is made of heavy duty steel
cable, with a strong scissor hood (2) at one end, and an equally strong spring hook (3) at the other.
Cotter pin (4) is supplied to secure the installation. For proper attachment to the broiler, use the supplied
hardware to attach the device to the holes in the shear plate of the broiler stand.
noTe: If disconnection of the restraint is necessary, reconnect the restraint after the appliance
has been returned to its originally installed position.
b.9 electrical Connection
Power requirements are stated on the unit nameplate and must be connected accordingly. This appliance, when installed must be electrically grounded in accordance with local codes, or in the absence of
local codes, with the National Electrical Code, ANSI/NFPA 70, or the Canadian Electrical Code, CSA
C22.2, as applicable. Before starting broiler, tighten all electrical connections in control box. An electrical
wiring diagram can be found inside the control box.
note: Disconnect power before servicing.
b.10 Pre-operation Check
Be sure that all parts are installed in the proper location:
Ventilation is turned on
Broiler is plugged in
Gas line is connected

The JF93 is equipped with automatic ignition. When the broiler is turned on, a hot surface ignitor turns on 5 seconds
before the flow of gas. Gas then flows to all of the burners. If the burners are not lit within 10 seconds, the control will
reset and try again for 10 seconds. This occurs 3 times. If the broiler does not light after the third attempt, the ignition
failure light will flash and the main on/off switch must be cycled to repeat the procedure. If this still doesn’t light the
broiler, see the MANUAL IGNITION instructions.

2. TeMPeRaTURe ConTRol
Gas broilers are equipped with a Broil Temperature Stabilizer Control that senses when the
broiler is being used, and adjusts the temperature to keep the broiler hot during heavy use.
The control consists of two parts - a temperature probe to sense the internal temperature of
the broiler, and the control itself.
3. CalIbRaTInG THe TeMPeRaTURe ConTRol
In order to assure proper operation, the Temperature Control must be set for operation in the restaurant. Follow these
step by step instructions when the broiler is new, and once per month after.
Step 1: Be sure all pieces of the broiler are in place. Make sure the broiler is plugged in and the exhaust hood is turned
on. Turn the broiler on.
Step 2: Flex side: Set the temperature (bottom number) to 1000º F (537° C). Use the up or down arrows on the control
to set the temperature. Leave the broiler at 1000º F for one hour. DO NOT COOK DURING THIS HOUR. After
the hour is up, use the arrows to put the set point to 20º UNDER the actual temperature. The bottom number is
the set temperature and the top number is the actual temperature.
