INTRODUCTION
RECEIVING THE APPLIANCE
Upon receipt of the appliance, 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, make a written request for inspection by the carrier's agent within
15 days of delivery. All packing material should be kept for inspection.
merchandise to Lang Manufacturing Company.
Uncrate the appliance 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.
File your claim with the carrier.
MODEL NUMBERS
The CR-30 range is available in several different models.
The ovens are supplied with a mechanical thermostat control (Accutemp) or a solid state temperature
selector (Selectronic).
The range top can be supplied without an oven and installed on 4 inch legs.
The range top is offered with three types of cooking surfaces, these are: round french plates, an 18 inch
griddle, and a 12 inch hot top.
Do not return damaged
The model number contains information about the range configuration, below is an example.
1. S = Selectronic, T = Accutemp
2. CR = Convection Range, RT = Range Top Only
3. 30 = 30 inches wide
4. G = Griddle, H = Hot Top, S = French Plates
5. (Optional) M = Marine Approved (Not shown above)

VENTILATION AND CLEARANCES
Standard minimum clearance from
2 inches from sides
4 inches from back
4 inches from floor
Keep the appliance area free and clear of combustible material and do not obstruct the flow of ventilation
air.
The installation of any components such as a vent hood, grease extractors, and/or fire extinguisher systems,
must conform to the their applicable nationally recognized installation standards.
combustible
construction is as follows:
ASSEMBLY
TOE BASE
Assemble the toe base prior to installing it on the oven.
1. Bolt the sides, front, and back using eight 10-32 X 1/2 screws, nuts, and lockwashers.
2. Gently tip the oven forward and install two 3/8 X 1 1/4 studs (provided in toe base hardware) into
threaded inserts for the rear oven legs.
3. Place the toe base into position with the front flange facing forward (make sure the base is square).
4. Place the oven onto the toe base so that the studs in the rear threaded inserts nest into the holes at the
rear of the toe base.
5. Thread two 3 / 8 bolts and washers (p rovided in toe base hardware) thro ugh t he base’s front flange and
into the threaded inserts for the oven’s front legs.
RANGE TOP TO OVEN
The range top is shipped assembled to the oven base but, can be separated from the oven if necessary.
1. Remove the panel from the side of the oven, over the control compartment.
2. Note the location of the four wires coming from the range top and remove them from the circuit
breakers.
3. Remove two bolts, that hold the range top to the oven, from the front of the oven at the upper left and
right corners.
4. Remove three sheetmetal screws from the strap on the back of the oven.
5. Lift the range top from the oven.
Reverse the above procedure to install the range top.

ELECTRICAL CONNECTION
Refer to the
Refer to the Data Plate located behind the louvered door below the oven control compartment to confirm
the range voltage matches the voltage at the installation site. Contact the factory if the voltages do not
match.
The electrical connection must be made in accordance with local codes or in the absence of local codes with
NFPA No. 70 latest edition (in Canada use: CAS STD. C22.1).
The electrical service entrance is provided by a 1 1/4 inch knockout located at the back of the appliance
directly behind the control compartment.
Supply wire size must be large enough to carry the amperage load for the type of appliance being i nst alled.
Wire size information can be found on the data plate.
Refer to the wiring diagram at the back of this manual to group the supply wires to match the power phase.

OPERATION
INITIAL START UP
SETTING THE GRIDDLE TEMPERATURE
Turn the temperature dial located on the upper control panel until the desired temperature is at the top of the
dial.
An indicator lamp located next to the thermostat dial will go off once the griddle has reached the set
temperature.
SETTING THE BURNER SWITCHES
The round burners are controlled by six-heat switches. Turn the switch to the Hi position until the desired
product temperature is achieved then turn the dial to a lower setting to maintain the product temperature.
DO NOT allow the burner to remain on Hi with no product on the burner.
CLEANING THE COOKING SURFACE
The upper cooking surfaces are coated with a preservative coating to prevent rust.
Heat the griddle and/or the burners to a temperature that just turns the preservative into a liquid then turn
off the cooking surface. DO NOT heat the cooking surface over 150 degrees.
Wipe the coating off of the surface with a rag.
Dampen a rag with lighter fluid and wipe the remainder of the coating off of the cooking surface.
DRYING THE HEATING ELEMENTS
The heating elements should be brought to operating temperature slowly. Water trapped inside the
elements will vaporize and damage the element if not dried from the element before it reaches an elevated
temperature.
Heat the griddle to 200 degrees for 2 hours then proceed with the seasoning process.
Shipboard note:
fault detectors.
The entire range may need to be run for several hours before it will not trip the ground
SETTING THE OVEN TEMPERATURE
Set the toggle switch located on the lower control panel to the On (up) position.
Turn the temperature dial located on the lower control panel until the desired temperature is at the top of the
dial.
An indicator lamp located next to the thermostat dial will go off once the oven has reached the set
temperature.
SEASONING THE GRIDDLE
The griddle surface must be seasoned in order to eliminate product sticking.
To season, heat the griddle to 250 degrees.
Once at 250 degrees, coat the cooking surface with a non-salted vegetable oil.
Allow the griddle to stand at 250 degrees until the cooking surface looks dry then coat it again.
5
Heat the griddle to 350 degrees and repeat the procedure.
Product may still stick slightly for the first few loads of product.
NOTE:
Do not be alarmed as the smoke is caused by oils associated with the manufacturing process and will stop
when the griddle reaches 350 degrees.
The griddle may emit a small amount of smoke as the cooking surface passes the 300 degree point.
OPERATING THE OVEN
A convection cooks by circulating heated air around the product. The blower strips off the layer of cold,
moist air from around the product and allows the heat of the oven to penetrate the product more efficiently.
Best results will be obtained if the product is loaded into the oven evenly. Space should be maintained
around the pan and oven walls.
Convection oven cooking temperatures can typically be set 25 degrees lower than deck ovens.
Do not cover the product with anything that will restrict the flow of air.
Open the oven door as few times as possible and for as short a time as possible. The secret to even baking
is to cook with "stored" oven heat. Stored heat means, heat that is in the oven cavity without having to turn
the oven elements on. Whenever the oven elements must come on, hotter air is circulated into the oven
cavity, product that comes in contact with this air may cook differently than product which is exposed to the
lower temperature "stored" heat.
Load the convection oven starting from the middle rack position, working up and down on the evenly
spaced oven rack positions.

MAINTENANCE
DAILY CLEANING
Empty the grease drawer daily or whenever it is 3/4 full. It is easily removed for cleaning.
There is a mark on the grease drawer to indicate when the drawer is considered full.
WARNING
USE CAUTION WHEN REMOVING THE GREASE DRAWER AS IS CONTAINS HOT GREASE!
Clean the exterior of the appliance with a hot water and mild detergent to maintain a gleaming appearance.
Keep the griddle surface clean. After each cooking load scrape the surface to remove any carbonized
grease.
CAUTION
WHEN SCRAPING THE GRIDDLE SURFACE, DO NOT ABRADE THE SPLASH GUARD. IT MAY EVENTUALLY CUT
THROUGH.
WEEKLY CLEANING
Once a week or when necessary the griddle surface should be thoroughly cleaned and reaseasoned. Use a
griddle stone, griddle pad, or liquid cleaner.
A mild detergent with water or one of the many commercial griddle cleaners may also be used.
Be sure to rinse thoroughly and coat the cooking surface with a thin film of oil to prevent rusting.
Reseason the griddle plate after each cleaning.
