EQUIPMENT DESCRIPTION
Exterior Construction
The griddle dimensions are 17” (43.18cm) High, 30” (76.20cm) Deep, and width is dependent on the
actual model number.
The Sides, Bottom, and Rear wall are constructed of double wall stainless steel, which allows closer
installation to combustible surfaces.
The stainless steel drop-down door keeps the controls cool and control area clean.
The griddle surface is made of 1” thick, highly polished steel to reduce hot and cold spots, recovery
problems, warping, and ensure even heat to the edges of the griddle.
Controls
The Selectronic Griddle comes with the solid state controls which include:
• A Main Power Switch & Power Indicator for the entire unit.
• Each twelve-inch section has its own temperature selector switch that snaps into place to lock in
any temperature from 175°F to 450°F (79°C to 232°C) in 25° increments.
• Each twelve-inch section of the griddle is controlled by an area sensitive RTD probe, which can
sense and react to a temperature change of +/- 4°F.
Technical
• Griddle operates on either Natural gas or Propane. This must be specied when ordering. It is
shipped with a Power Cord and Plug attached.
• Floor space required is 30” (76.20cm) Deep, and width is 2 ft, 3ft, 4ft, 5ft, or 6ft depending on actual
model number.
• The griddle weighs 260, 390, 520, 650, 780 lbs. depending on actual model number.

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 Star Manufacturing Company. File your claim with the
carrier.
Location
Prior to un-crating, move the oven 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 oven 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 OVEN WILL BE
LOCATED MUST BE DESIGNED TO SUPPORT THE WEIGHT OF THE GRIDDLE.
SHIPPING STRAPS ARE UNDER TENSION AND CAN SNAP BACK WHEN CUT.
VENTILATION & CLEARENCE
CLEARANCE
For use on non-combustible countertops only.
Combustible and non-combustible material must be at least 48” (120cm) from the top of the
appliance and 5” (150mm) from the sides and back. Adequate clearance should also be provided
for proper operation and servicing.
AIR SUPPLY
Make certain not to obstruct the  ow of combustion and ventilation air. Provisions for adequate air
supply must be furnished. The legs supplied with the unit must be installed. Make certain that air
intake openings in the bottom of the appliance are not obstructed. They are essential for proper
combustion and operation of the appliance.
EXHAUST CANOPY
It is essential that facilities be provided over the griddle to carry off fumes and gases. However,
the unit should not be directly connected to a  ue or stack.
CAUTION

INSTALLATION
Leg Installation
There are four, adjustable legs provided for
Enviro-Zone griddles.
The legs are shipped in the grease drawer(s)
of the griddle. Install them into the threaded
holes on the underside of the griddle body.
Leveling adjustment may be done by screwing
the bottom portion of the leg in and out.
Electrical Connection
The griddle is supplied with a cord and plug.
The receptacle is not provided with the griddle.
Follow the receptacle manufacturer’s
instructions when connecting the receptacle to
the power supply.
Gas Connection
This griddle is manufactured for use with the
type of gas indicted on the nameplate.
Contact the factory if your type of gas does not
match the nameplate data.
All gas connectors must be in accordance with local codes and comply with the National Fuel Federal
Gas Codes ANSI Z223.1 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.
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 specied is supplied with each appliance.
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.
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 grease gutter and provide the proper combustion air for the
burners.

INITIAL START UP
Initial Lighting Procedure
Clean the preservative coating from the griddle plate and splash guard. Add a mild detergent to hot
water and wash the griddle plate and splash guard. Rinse with a damp sponge and dry with a clean
rag.
WARNING: BEFORE LIGHTING, USE A SOAP AND WATER SOLUTION TO
TEST ALL JOINTS FOR GAS LEAKS.
• Plug the unit into a 115-volt power supply.
• Turn the ON-STANDBY toggle switch to ON.
• Set the temperature dials to the desired temperature.
• Turn the toggle switch to each section to ON.
• To turn the griddle off, simply turn the main toggle switch to STANDBY.
Seasoning the Griddle Plate (non chrome only)
• Set the temperature dials to 300°F (148°C).
• Observe the burners through the opening at the top of the control panel.
• When the burners go OFF, apply a thin coat of high-grade, non-salted vegetable oil to the
griddle surface.
• Rub the oil into the griddle surface with the at side of a spatula or a towel.
• Recoat any dry spots that appear then wait two minutes and wipe off any excess oil.
• Repeat the seasoning process at 350°F (176°C) and at 400°F (204°C).
NOTICE: Duringtherstfewhoursofoperationyoumaynoticeasmall
