B. INSTALLATION
PRE-INSTALLATION
Uncrate the broiler, and inspect for shipping damage. Contact the factory if there is obvious damage.
Remove the tape securing the machine parts, and install the parts in their proper location. Refer to the
Parts and Location section of this manual. If you find concealed damage to any part of this unit, contact
your freight carrier immediately. The factory warranty does not cover freight damage.
MOUNTING
If the broiler was shipped with a tubular stand, refer to separate tubular stand assembly instructions.
Note: The four legs of the broiler stand are equipped with casters. Always set the brakes on the
casters to prevent the broiler from shifting during operation or cleaning.
HOOD REQUIREMENTS
This appliance must be installed under a ventilation hood of adequate size and capacity (see chart).
Model CFM CMH
732/735 800 1360
532/535 600 1020
522 400 680
The hood should be at least 6" (152MM) larger in all dimensions than the appliance top, and be 12" to
18" (305MM - 457MM) above the top. Do not obstruct the flow of combustion and ventilation air. An ade-
quate air supply must be available for safe and proper operation.
Note: See the National Fire Prevention Association booklet on ventilation of cooking equipment.
Write to: NFPA, 470 Atlantic Ave., Boston, MA 02210. Local codes on venting must also be com-
plied with.
CLEARANCE
For proper installation, the minimum clearance from combustible and non-combustible construction is 6"
(152MM) from the back and 6" (152MM) from the front of the machine. Keep appliance area free from
combustibles.
To facilitate disassembly and service of the unit a minimum of 24" (610MM) should be allowed on the
control panel (right) side of the broiler, as well as in front of the broiler.
GAS CONNECTION
At rated BTU capacity, the gas supply should deliver a pressure of at least 6" water column at the broiler
connection for natural gas, and 11" water column for propane gas. Incoming gas supply pressure must
not exceed 14" water column for either type of gas.
The appliance was shipped from the factory ready for gas supply hook-up to the shutoff valve under the
broiler. For disconnect, a manual valve must be located in the gas supply line upstream from the con-
necter.
If the machine is installed on a moveable stand; (1) the installation shall be made with a connector that
complies with the Standard for Connectors for Moveable Gas Appliances, ANSI Z21.69-1987, and
Addenda, Z21.6a-1989, and a quick disconnect device that complies with the Standard for Quick-
Disconnect Devices for Use With Gas Fuel, ANSI Z21.41-1989, and (2) adequate means must be provid-
ed to limit the movement of the appliance without depending on the connector and the quick-disconnect
device or its associated piping to limit the appliance movement. (See figures on page 7.)
Note: Appliance installation must conform with all local codes, or in the absence of local codes,
with the National Fuel Gas Code ANSI Z223.1-1988. Check all fittings for gas leaks, including
pilot tubing and inlet connections as soon as the appliance is connected to the gas supply.
