INSTALLATION

RECEIVING THE OVEN

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. Do not

return damaged merchandise to Lang
Manufacturing Company. File your claim

with the carrier.
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.

DATA PLATE INFORMATION

A data plate is located inside the control
compartment above the control. Look through
the perforated opening above the control panel
and to the left to view the data plate. A
flashlight may be helpful.

The oven voltage, wattage, serial number, wire
size and clearance specifications are on the data
plate.

This information should be carefully read and
understood before proceeding with the
installation.

VENTILATION AND
CLEARANCES

Standard minimum clearance from combustible
construction is as follows:

2 inches from sides
4 inches from back
6 inches from floor

These ovens may be set directly, without legs, on
a curbed base or non combustible floor.

If the oven is set without legs on a non
combustible floor or a curbed base, maintain a 4
inch back clearance.

If the oven is set directly against a non
combustible back wall, maintain a 6 inch
clearance to the floor.

Do not install the oven closer than 3 inches from
another oven on the right hand side (control
panel side).

Do not install the oven closer than 12 inches
from an uncontrolled heat source (char broiler
etc.) on the right side.

Keep the appliance area free and clear of
combustible material and do not obstruct the
flow of combustion or 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.

LEGS

Legs are available for both the single and double
deck installations. Single deck installations
require a 27 inch leg. Double deck installations
require a 6 inch leg or caster.

To install the 27 inch legs, place 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 diameter bolts provided in the leg
kit. Lift the oven onto the front legs and block
the back of the oven using one of the 27 inch
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 and 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/caster to the supports supplied with the oven
(located inside the oven cavity in a box labeled
Leg Pads). Follow the instructions in the Leg
Pad box to attach the pad to the oven.

The adjustable feet on the bottom of each leg
may be screwed in or out as necessary to level
the oven.

1

A spirit level, placed on an oven rack, will assist
in leveling the oven.

STACKING THE OVENS

Remove all of the plug buttons from the top of
the lower oven.

Remove the stacking kit from the oven
compartment.

All gas connections must be in accordance with
local codes and comply with the National Fuel
Gas Code ANSI Z223.1 latest edition.

A 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.

Tip the top oven backwards and install two 3/8
diameter Allen 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
Allen Head bolts with the heads of the bolts
pointing away from the oven.

Lift the top oven and gently set on top of the
lower so that the heads of the bolts ne st into the
holes in the top of the lower oven.

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.

GAS CONNECTION

DANGER

AS WITH ANY GAS APPLIANCE INSTALLED ON CASTERS,
ANY LANG GAS GRIDDLE, GAS CLAMSHELL®, OR GAS
CONVECTION OVEN ON CASTERS MUST BE INSTALLED
WITH THE FOLLOWING:

A CONNECTOR THAT COMPLIES WITH THE STANDARD
FOR CONNECTORS FOR MOVABLE GAS APPLIANCES,
ANSI Z21.69 LATEST EDITION.

AND

A QUICK DISCONNECT THAT COMPLIES WITH THE
STANDARD FOR QUICK DISCONNECT DEVICES FOR USE
WITH GAS FUEL, ANSI Z21.41 LATEST EDITION.

AND

A TETHER OR OTHER MEANS TO LIMIT APPLIANCE
MOVEMENT WITHOUT RELIANCE ON THE GAS SUPPLY
PIPING. SECURELY ATTACH THE TETHER TO THE
EYEBOLT PROVIDED AT THE REAR OF THE APPLIANCE.

FAILURE TO INSTALL THESE PARTS CAN LEAD TO
LEAKAGE OF GAS AND RESULTING FIRE, EXPLOSION,
PERSONAL INJURY AND DEATH.

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.

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 1/2 inch
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.

WARNING

DO NOT USE AN OPEN FLAME TO TEST
FOR GAS LEAKS.

ELECTRICAL CONNECTION

WARNING

ELECTRICAL GROUNDING

INSTRUCTIONS

2

THIS APPLIANCE IS EQUIPPED WITH A 3­PRONG (GROUNDING) PLUG FOR YOUR
PROTECTION AGAINST SHOCK HAZARD
AND MUST BE PLUGGED DIRECTLY
INTO A PROPERLY GROUNDED 3­PRONG RECEPTACLE.

DO NOT CUT OR REMOVE THIS
GROUNDING PRONG FROM THE PLUG.

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.

INITIAL START UP

WARNING

PRIOR TO STARTING THIS APPLIANCE,
THE MAIN GAS VALVE MUST BE OFF
FOR AT LEAST FIVE MINUTES.

The pilot burner is electronically ignited. When
the oven power switch is turned On the pilot will
light.

There is a lockout safety feature on the spark
ignition module. If, during the initial start-up, the
pilot does not light within 30 seconds the module
will turn off all gas to the pilot burn er. To reset
the spark module, turn Off the power switch for
10 seconds then turn the switch back On. This
may need to be repeated several times during the
initial start-up until gas is present at the pilot
burner.
