CAUTION
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 it 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. File your claim with the carrier.
Location
Prior to un-crating, move the griddle as near to 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.
Cut the straps and remove the wood frame.
The griddle can now be removed from the skid.
THE UNIT 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.
ANY STAND, COUNTER OR OTHER DEVICE ON WHICH GRIDDLE WILL BE
LOCATED MUST BE DESIGNED TO SUPPORT THE WEIGHT OF THE GRIDDLE.
SHIPPING STRAPS ARE UNDER TENSION AND CAN SNAP BACK WHEN CUT.
LEG INSTALLATION
The legs are installed by sliding the threaded ends of the
legs into the leg receiver tubes located in each corner of
the griddle.
Slide the leg up until contact is made with the threaded
nut at the top of the reciever tube. Screw the leg counterclockwise until it is hand tight.
After the griddle is in its nal position, adjust the legs to
create 1/8 inch slant from back to front. This will allow the
grease to run into the front grease gutter and provide the
proper combustion air for the burners. It will also allow
exposed gasses to escape out the rear of the unit.
Level unit by adjusting the (4) legs for accurate and perfect
lineup with other units.

This regulator must be installed in the gas supply line. (Note the direction of the gas ow arrow.)
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 re. 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 should 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
