B. INSTALLATION

B.1 Pre-Installation

Uncrate the broiler and inspect for shipping damage. Remove the tape securing the machine par ts, and
install the parts in their proper location. Refer to the Parts and Location section of this manual. 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 to level
the broiler during installation. Use levelling shims (P/N 11936).

that stand is level within 1/8”. If not,
shim as required.

SHIM INSTALLATION:

1. Prior to mating stand to broiler and with stand in operating position, verify
that stand is level within an 1/8”inch.

2. If shimming is required, determine which caster(s) should be shimmed.

3. Elevate side of stand to be shimmed off of floor.

4. Remove caster(s) to be shimmed.

5. When installing shims, remove existing hardware, discard washers (ITEM 2),
and reuse nuts and bolts.

6. After adding shim(s) and securing caster(s), lower broiler.

7. Check to verify that broiler is now level.

12” (305mm) Minimum, preferably 610 mm (24”) or more for service. Location clearances are from walls of broiler height.

B.4 Hood Requirements

This appliance must be installed under a ventilation hood of adequate size and the following minimum
capacity:

Model SCFM
8025 1050

Do not obstruct the flow of combustion and ventilation air. An adequate air supply must be available for
safe and proper operation.

B.5 Clearance

For proper installation the minimum clearance from combustible and non-combustible construction must
be 305 mm (12”) from the back and 305 mm (12”) from the front of the machine.Keep appliance area
free from combustibles.

To facilitate disassembly and service of the unit a minimum of 610 mm (24”) should be allowed on the
control panel (feed end) of the broiler, as well as in front and back of the broiler.

B.6 Gas Connection- 1” N.P.T. (Nieco P/N 11966; 1” Flexible Gas Line)

At rated input the gas supply should deliver a minimum pressure of at least 15 mbar (5" 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.

Nieco Corporation - Model 8025

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 Quick-Disconnect Devices for
use with gas fuel, ANSI Z21.41 or CAN1-6.9

In order to avoid sharp kinks or excessiv e 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.)

B.7 Installing Gas Appliance Connectors and Flexible Gas Lines Correctly

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.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 Electr ical Code, CSA
C22.2, as applicable.Before star ting 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

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.
