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. 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
B.2.1 Remove all parts from the broiler. B.2.2 Lift broiler onto stand. NOTE: The cross bar on the base of the stand should be on the
discharge (back side) end of the broiler. B.2.3 Use the supplied nuts and bolts to bolt the frame of the broiler to the stand. B..2.4 Follow the steps outlined in the manual to reassemble the broiler.
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.
B.4 Hood Requirements
This appliance must be installed under a ventilation hood of adequate size and the following minimum capacity:
Model SCFM
N1535 600
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 required clearance from combustible construction and walls is 12” (305 mm) from all sides of the broilers.The minimum required clearance from non-combustible construc­tion and walls is 0” (0 mm) from all sides of the broiler. Keep appliance area free from combustibles. Check with local authorities (building and fire) for standards and requirements for wall and floor con­struction to comply with your local codes.
REQUIRED for installation near combustible walls and construction
REQUIRED for installa­tion near non-com­bustible walls and construction
RECOMMENDED by Nieco for proper disas­sembly and service

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 (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 N1535
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.
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.)

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.
C.TROUBLESHOOTING
Problem Solution
Pilots not lighting ❏ Check that broiler is plugged in, gas valve is
open and broiler is turned on

❏ Check for gas pressure, if there is pressure,
use the manual lighting procedure
❏ If no gas pressure, call for service ❏ Check for proper burner installation ❏ Check for plugged burner orifices ❏ Check for plugged pilot burner
Pilot not staying lit
❏ Call for service as thermocouple may need
replacing
Broil chain jams
❏ Check:
__ For sag in the chain (Chain may need a
link removed)
__ For an obstruction
9
Always verify that the broiler is properly assembled, the hood is on, gas valve open and broiler is plugged in.
