INITIAL START UP
Prior to putting any oven into full time operation at normal cooking
temperatures, it must be thoroughly “seasoned” or dried out. Moisture
absorption in the closed spaces, in the insulation and even inside the
heating elements can cause future trouble if not properly treated.
Before the initial use of the oven, they must be thoroughly allowed to dry
out. This is done by setting the top and bottom oven switches to the “low”
position, and setting the thermostat to 350 degrees. Allow the range ovens
to saturate until all vapor and condensation has been eliminated. For best
operating results allow the ovens to thoroughly dry out. Allow 8 to 12 hours
for this process.
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
NOTICE:
During the first few hours of operation you may
notice a small amount of smoke coming o the
melter, and a faint odor from the smoke. This is
normal for a new melter and will disappear after the
first few hours of use.

OPERATION
CAUTION:
ALWAYS KEEP THE AREA NEAR THE APPLIANCE
FREE FROM COMBUSTIBLE MATERIALS.
CAUTION:
KEEP FLOOR IN FRONT OF EQUIPMENT CLEAN
AND DRY. IF SPILLS OCCUR, CLEAN IMMEDIATELY,
TO AVOID THE DANGER OF SLIPS OR FALLS.
Ovens
The ovens must be thoroughly, preheated before satisfactory baking can be
done. The ovens will not bake uniformly if not suciently preheated.
To compensate for temperature drop when loading the ovens, set the
thermostat up 50 degrees over the desired temperature. Reset thermostat
after the ovens is loaded.
The ovens may, of course, be preheated with the 3 heat switches set at a
lower position than “High”, but the time required will be proportionally
longer. After preheating, set the two 3 heat switches for proper ratio of “top”
and “bottom” heat to suit the product to be baked or roasted.
The “Roasting and Baking” 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.
The following temperature, time, switch setting and rack positions are
suggested as a guide in baking various classes of products:

• Allow the oven to Preheat for at least half an hour.
• Note cycle on temperatures and cycle o temperatures for 3 cycles. (Red
indicator light indicates when oven is calling for heat)
• After 3 cycles average the temperature. ( Add all six temperatures and divide by 6)
Calibration Adjustment
• A 1/16” flat blade screwdriver with a 2” shaft is required to make adjustments on the
thermostat.
• Maintain the oven temperature at 350°.
• Without turning the thermostat, remove the knob.
• Locate the adjustment screw at the base of the shaft and insert the screwdriver.
• Grasp the shaft and turn the screwdriver. Counter clockwise to increase and clockwise to

original installation or up to six [6] months after the original shipment, from
the factory, of the covered product. Defects that occur as a result of normal
use, within the time period and limitations defined in this warranty, will at
Lang’ discretion have the parts replaced or repaired by Lang or a Lang-
authorized service agency.
THIS WARRANTY IS SUBJECT TO ALL LISTED CONDITIONS
Repairs performed under this warranty are to be performed by a Lang
authorized service agency. Lang will not be responsible for charges incurred
or service performed by non-authorized repair agencies. In all cases, the
nearest Lang-authorized service agency must be used. Lang will be
responsible for normal labor charges incurred in the repair or replacement
of a warrantied product within 50 miles (80.5 km) of an authorized service
agency. Time and expense charges for anything beyond that distance will
be the responsibility of the owner. All labor will need to be performed
during regular service hours. Any overtime premium will be charged to the
owner. For all shipments outside the U.S.A. and Canada, please see the
International Warranty for specific details. It is the responsibility of the
owner to inspect and report any shipping damage claims, hidden or
otherwise, promptly following delivery. No mileage or travel charges will be
honored on any equipment that is deemed portable. In general, equipment
with a cord and plug weighing less than 50 lb. (22.7 kg) is considered
portable and should be taken or shipped to the closest authorized service
agency, transportation prepaid.
