UNPACKING
Receiving the Griddle
Upon receipt, check for freight damage, both visible and concealed. Visible
damage should be noted on the freight bill at the time of delivery and signed by the
carrier's agent. Concealed loss or damage means loss or damage, which does not
become apparent until the merchandise has been unpacked. If concealed loss or
damage is discovered upon unpacking, make a written request for inspection by the
carrier's agent within 15 days of delivery. All packing material should be kept for
inspection. Do not return damaged merchandise to Lang Manufacturing Company.
File your claim with the carrier.
Location
Prior to un-crating, move the griddle as near its intended location as practical. The
crating will help protect the unit from the physical damage normally associated
with moving it through hallways and doorways.
Un-crating
The griddle will arrive completely assembled inside a wood frame and strapped to a
skid. Remove the wood frame and cut the straps.
CAUTION THE GRIDDLE IS EXTREMELY HEAVY. FOR SAFE HANDLING, INSTALLER
SHOULD OBTAIN HELP AS NEEDED, OR EMPLOY APPROPRIATE
MATERIALS HANDLING EQUIPMENT (SUCH AS A FORKLIFT, DOLLY, OR
PALLET JACK) TO REMOVE THE UNIT FROM THE SKID AND MOVE IT TO
THE PLACE OF INSTALLATION.
CAUTION ANY STAND, COUNTER OR OTHER DEVICE ON WHICH THE GRIDDLE
WILL BE LOCATED MUST BE DESIGNED TO SUPPORT THE WEIGHT OF
THE GRIDDLE.
CAUTION SHIPPING STRAPS ARE UNDER TENSION AND CAN SNAP BACK WHEN
CUT.
The griddle can now be removed from the skid and placed in its intended location.
Appliances installed on caster must use connectors complying with ANSI Z21.69
and quick disconnect complying with ANSI Z21.41. It must also be installed with
a restraining device to prevent strain against the gas connections. A restraining
point is provided at the rear of the grill.

INSTALLATION
WARNING INSTALLATION OF THE UNIT MUST BE DONE BY PERSONNEL QUALIFIED
TO WORK WITH PLUMBING. IMPROPER INSTALLATION CAN CAUSE
INJURY TO PERSONNEL AND/OR DAMAGE TO EQUIPMENT. UNIT MUST
BE INSTALLED IN ACCORDANCE WITH ALL APPLICABLE CODES.
NOTICE The data plate is located inside the control compartment on the left wall of
each griddle. The griddle serial number, gas specifications, and clearance
specifications are on the data plate. This information should be carefully
read and understood before proceeding with the installation.
NOTICE The installation of any components such as a vent hood, grease
extractors, fire extinguisher systems, must conform to their applicable
National, State and locally recognized installation standards.
Gas Connection
This griddle is manufactured for use with the type of gas indicted on the nameplate.
If your type of gas does not match the nameplate data consult the conversion
instructions in this section of the manual.
All gas connectors must be in accordance with local codes and comply with the
National Fuel Federal Gas Codes ANSI Z223.1, Natural Gas Installation Code
CAN/CGA-B149.1, or the Propane Installation Code, CAN/CGA-B149.2 latest
edition.
This appliance should be installed with a separate gas valve in the gas line ahead of
the unit. Use a 3/4-inch or larger gas supply line. The gas should be installed in one
of two locations, from under the body or from the back. The plug must be
installed on the connection not used.
Remove the 5/16-inch nuts securing the rear of burners. These nuts are for
securing the main burners during transportation only. The rear burner shield must
be removed to gain access to the nuts.
A pressure regulator for the type of gas specified is supplied and already installed
with each griddle. The pressure in the manifold of the appliance should be tested
with a manometer and the regulator adjusted for proper pressure with the appliance
operating at full fire. A 1/8-inch NPT tap is provided in the manifold for
connecting a manometer.
Correct manifold pressures are:
5 inches water column for natural gas
10 inches water column for propane
When replacing the plug in the manifold, a pipe joint compound or sealant must be
used that is resistant to the action of liquid petroleum gas.
Initial adjustments are the responsibility of the installer and are not chargeable to
Lang Manufacturing Company.
