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 ounting
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 and the following minimum
capacity:
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 MPB84.
B.5 Clearance
eep 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).
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 Quick-
Disconnect 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. ( inimal movement is
possible to connect hose.)
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.
