Electric range tops consist of various top arrangements, depending upon the specific
models purchased.
Options include 1.) 12" x24" hot plates
2.) Round speed units
3.) Griddles
4.) Induction Burners
Three position switches, thermostats, or infinite controls independently control these
units.
All thermostats are used in conjunction with a red indicator or pilot lamp. When the light
is on the elements are energized and bringing the plate to the temperature set on the
thermostat. When the light is off the plate has reached the temperature set on the
thermostat. Griddle pilot lights should be allowed to cycle at least twice before usage.
Recommended Usage:
1.) 12" x 24" hot plates. - Heavy stockpots and kettles.
2.) French Plates- Light duty saucepans and small stockpots.
(NOT recommended for large stockpots.)
3.) Griddles - Used for grilling product directly on surface.
CAUTION
All hot plates and speed units should be turned to the low or off position when not in use.
Allowing these elements to stay in the full on or high position with nothing on top to
absorb and dissipate the heat is detrimental to element life. Lang warranty provisions do
not cover abuse of this nature.
INITIAL START-UP
Hot Plates
To “dry out” the hot plate, set the thermostat dial at 250°F and turn on the power switch. Allow
unit to cycle at least 15 minutes at this heat level. Reset the thermostat to 350°F allowing the
same time. Then reset the thermostat to 450°F allowing the same time. Continue doing this
until you reach 850°F then allow the unit to maintain this temperature for a minimum of 4 hours.
More time may be required if the unit has to operate in a moist environment.
If the unit is out of use for three or more days, a one-hour preheat schedule should be used, especially when
exposed to high humidity and/or cool temperatures.
French Plates
To “dry out” the French plate, set the six-heat switch to the first setting and turn on the power
switch. Allow unit to cycle at least 15 minutes at this heat level. Reset the six-heat switch to
position 2 and allow the same time. Reset the six-heat switch to position 3 and allow the same
time. Continue doing this until you reach position 6 then allow the unit to maintain the
temperature for a minimum of 4 hours. More time may be required if the unit has to operate in a
moist environment.
If the unit is out of use for three or more days, a one-hour preheat schedule should be used,
especially when exposed to high humidity and/or cool temperatures.
Page 6
Induction Burners
Induction requires cookware that is induction efficient or that is made for use on an induction
surface. Generally speaking if a magnet attracts and strongly adheres to the pan bottom it will
generally work on an induction surface. This is a requirement for proper use.
DO NOT USE WITH EMPTY PANS.
To operate unit turn the knob clockwise and a small digital number will appear next to the
hotplate to be cooked on. The higher the number the faster the heat up. Heating will begin
when the pan surface comes in contact with the induction surface and will cease when the pan is
removed. Note: surface will remain hot for a certain period of time after the pan is
removed.
Induction module, controlled by variable heat control. Great for rapid heat-up, it will generally
boil water, heat sauces or soups in about half the time of a French Plate. Use caution placing
items on the glass cook surface, always wipe down glass with mild soap and water to keep the
unit clean.
Griddles
To “dry out” the griddle, set the thermostat to 250°F and turn on the power switch. Allow the unit
to cycle at least 15 minutes at this heat level. Reset the thermostat to 350°F allow the same
time. Reset the thermostat to 450°F and allow the unit to maintain the temperature for a
minimum of 4 hours. More time may be required if the unit has to operate in a moist
environment.
If the unit is out of use for three or more days, a one-hour preheat schedule should be used,
especially when exposed to high humidity and/or cool temperatures.

OPERATING INSTRUCTIONS
COMMERCIAL ELECTRIC RANGE
General
The range is designed to give, well-regulated, uniform heat throughout the oven and
over the surface units. The oven and surface units should be thoroughly preheated
before being used. It is advantageous from an operating cost standpoint to operate
with the switches and/or thermostats set at the lowest position that will satisfactorily
perform the cooking being done.
Initial Use
Before the initial use of the range, the oven must be thoroughly allowed to dry itself
out. This is done by setting the top and bottom oven switches to the “low” position,
and setting the thermostat to 350°F. Allow the range oven to saturate until all vapors
and condensation have been eliminated. For best operating results allow the range
oven to thoroughly dry out. Allow 8 to 12 hours for this process. Clean top plates
thoroughly. Apply salad oil. Turn each plate switch or thermostat to a low position
and allow plate to heat for three hours.
Range Controls
Three heat switches or automatic thermostats control the top plate units. The range
is provided with an upper heating unit located in the top of the oven and a lower
heating unit located under the metal deck, in the bottom of the oven. Each heating
unit is independently regulated for proper ratio of "top" and "bottom" heat, to suit the
product being baked or roasted, by means of two 3-heat switches located in the
panel at the right of the range. The range oven is also provided with an adjustable,
automatic temperature control, the dial, which is located in the range switch panel.
The setting of the control dial establishes the average temperature to be maintained
in the range oven.
Operation
The range oven must be thoroughly, preheated before satisfactory baking can be
done. The range oven will not bake uniformly if not sufficiently preheated. To
compensate for temperature drop when loading the range oven, set the thermostat up
50 degrees over the desired temperature. Reset thermostat after the range is loaded.
The range oven may be preheated with the three (3) heat switches set at a lower
position than "High", but the time required will be proportionally longer. After
preheating, set both three (3) position heat switches for proper ratio of "top" and
"bottom" heat to suit the product to be baked or roasted.
The 12" high "Roasting and Baking" range oven is equipped with a removable rack.
For baking pies, bread, or for roasting operations, the rack may be placed directly on
the metal deck and the pans placed on the rack. For baking cakes or pastries, the
rack should be located in the lower position provided by the rack supports at the sides
of the range and the pans placed on the rack in this lower position.

Rack Position
Always place the pans symmetrically on the rack for best results. Keep the oven door closed as
much as possible. Excessive door opening will cool the front section of the oven and products
placed near the front are likely to bake slower. It is desirable to keep the front edge of the pans
at least several inches back from the inside of the door (when closed). Do not permit air from a
window or fan to blow into the oven; it will cause uneven heating.
Range Top
Consists of the various top arrangements, depending on specific model purchased:
12" x 24" hot plate controlled by indicating type three (3) heat switch or high temperature
thermostats. Temperature range 0-800°F (-18°C-427°C). Recommended: Stockpots and heavy
kettle work.
Round Speed Units, controlled by indicating type 3-heat switch. Temperature range is 0-800°F
(-18°C-427°C) Recommended: Light duty saucepans and small stockpots. Not Recommended:
heavy stockpots, heavy urns, or kettles.
12" x 24" or 24" x 24" grill plates, controlled by thermostats. Temperature range is 0-450°F (18°C -232°C). Recommended: All heavy and light frying. Set the thermostat dial at the desired
temperature. The red pilot light will be on until the desired temperature is reached. The pilot
light indicates when the plate is heating.
Care and Cleaning
The range should be thoroughly cleaned at least once a week in addition to the normal daily
cleaning to insure against the accumulation of foreign material. Keep inside of oven and metal
deck clean, particularly around door opening, door edges and at bottom of door opening so that
the door may close tightly. CAUTION: ANY OVEN CLEANER USED SHOULD BE MARKED:
"SAFE ON ALUMINUM."
Keep-drip pans under range top plates clean.
Keep hotplate and griddle surfaces clean.
Outside of range and top should be kept clean.
Electric equipment is clean and sanitary, but may become unsanitary if dirt is allowed to
accumulate on it. Take advantage of the clean, sanitary features of electric equipment, give it
the regular attention that it deserves, the same as any other highly perfected machinery, to
insure best results and continued high operating efficiency.
How to Order Parts
Be sure to give the SERIAL NUMBER of the range, when ordering parts. If a switch is required,
state for what size plate of the top surface or state if it is for the oven. Give description of other
parts.
