RECEIVING THE OVEN
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 loss or damage, which 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 Company. File your claim
with the carrier.
Prior to un-crating, move the oven 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.
LEG INSTALLATION
Legs are available for both the single and double deck installations. Single deck
installations require a 27-inch leg. Double deck installations require 6-inch legs or casters.
To install the 27-inch legs, place some cardboard on the floor and gently tip the oven onto
its back. Fasten two legs to the oven's front corners using the four 5/16 inch bolts provided
in the leg kit. Lift the oven onto its front legs and block the back up using one of the 27inch legs set upside down in the center rear of the oven body. Install the last 27-inch leg
onto the oven body on the control side rear. Gently lift the oven rear, remove the leg set to
support the oven center and install it on the last rear corner.
To install the 6-inch legs or casters, attach the leg or caster to the leg supports supplied in
the oven by following the instructions in the box, then attach the leg support to the oven.
The adjustable feet on the bottom of each leg may be screwed in or out as necessary to level
the oven.
A torpedo level placed on an oven rack will assist in leveling the oven.
INSTALLATION
STACKING THE OVENS
Remove all the plug buttons from the top of the lower oven.
Remove the stacking kit from the oven compartment of one oven and install the 1 1/4-inch
plastic bushing into the top of the lower oven.
Tip the top oven backwards and install two 3/8-inch socket head bolts, found in the stacking
kit, into the two front leg holes that match the holes in the top of the lower oven. Install the
socket head bolts with the heads of the bolt pointing away from the oven.
Lift the top oven and gently set on top of the lower oven so that the heads of the socket
head bolts nest into the holes in the top of the lower oven.
ELECTRICAL CONNECTION
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 cord and plug located at the oven back
directly behind the control compartment.
Each oven requires a 115-volt grounded supply and 7.1 amps.
Supply wire size must be large enough to carry the amperage load for the number of ovens
being installed. Wire size information can be found on the oven data plate.

INSTALLATION CONT’D
GAS CONNECTION
This appliance is manufactured for use with the type of gas indicated on the data plate.
Contact the factory if the gas type does not match that which is on the data plate.
All gas connections must be in accordance with local codes and comply with the National
Fuel Gas Code ANSI Z223.1 latest edition.
An internal gas pressure regulator is located inside the control compartment.
Gas must be delivered to the appliance regulator at less than 1/2 pound of pressure and less
than 1/2-inch water column pressure drop.
The internal regulator is preset at the factory, however, due to gas pressure variations from
area to area, adjust the regulator to provide the manifold pressure indicated on the data
plate. This should be 5 inches water column for natural gas and 10 inch water column for
propane. A 1/8-inch NPT tap is provided on the main manifold for checking regulator
pressure. Access the main manifold by removing the trim piece below the oven doors.
When replacing the 1/8-inch plug in the main manifold a joint sealant that is resistant to the
action of liquid petroleum gas must be used.
The supply piping must be of sufficient size to provide 55,000 BTU/hr per oven. A 1/2inch NPT connection is provided at the rear of the oven directly behind the control
compartment. Connect each oven separately.
A gas shut off valve must be installed to the oven(s) and located in an accessible area.
This appliance and its individual shutoff valve must be disconnected from the gas supply
piping system during any pressure testing of that system at test pressures in excess of 1/2
PSGI (3.45 kPA) and the appliance must be isolated from the gas supply piping system by
closing its individual manual shutoff valve during any pressure testing of the gas supply
system at test pressures equal to or less than 1/2 PSIG (3.45 kPA).
Test for gas leaks. Use a commercial leak detector or a soap and water solution.
FLU EXTENSION
A flu extension must be installed on the lower oven of a stacked set.
The extension attaches to the flu opening of the lower oven and directs the flu products
into the flu opening of the upper oven.
This extension must be installed.
The ovens may now be set into position. Be careful if sliding the ovens, they are not
designed to slide over cracks or obstructions in the floor.

programmed temperature.
Below is a list of displays and their definitions:
"
ENTER" The oven is energized and ready for an operator command.
"
PrEht" Stands for “PREHEAT”. A product has been selected and the oven is
heating to the programmed temperature.
"
rEAdY” A product has been selected and the oven has preheated to the
programmed temperature. The oven is ready to load a product.
"
COOL" The oven's internal temperature is below what is programmed.
"
Hot" The oven's internal temperature is above what is programmed.
"
ShELF" A product selection has been made after the oven has preheated and the
computer is asking which shelf the product is placed on.
"
hELP" There is a fault in the control system, the computer will not operate until
service is performed.
"
Cont" Stands for “CONTINUOUS”. The oven has been programmed without a
time being entered. The oven will operate continuously at the
programmed temperature.
"
