Leg Installation
Legs are available for single, double, and counter top installations. Single deck
installations require a 28-inch leg, double deck installations require a 16-inch leg,
and counter top installations require a 4-inch leg.
To install the 28-inch legs, place some cardboard on the floor and gently tip the
oven onto its back. Fasten two legs to the oven's front. Lift the oven onto its front
legs and block the back up using one of the 28-inch legs set upside down in the
center rear of the oven body. Install the last 28-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 16-inch legs follow the same instructions as the 28-inch legs.
To install the 4-inch legs, place some cardboard on the floor and gently tip the oven
onto its back. Fasten the four 4-inch legs into the threaded holes provided on the
bottom of the convection oven. Gently lift the oven onto the legs.
Stacking the Ovens
Stacking kits must be requested upon purchase.
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 pins into the front leg holes of the top
oven.
Lift the top oven and gently set on top of the lower oven so that the studs nest into
the holes of the lower oven.

INSTALLATION CONT’D
Ventilation and Clearances
Standard minimum clearance from combustible construction is as follows.
4” from side
4” from back
6” 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 4 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 there applicable nationally recognized
installation standards.
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: CSA STD.
C22.1).
The electrical service entrance is provided by a 1 1/4-inch knockout at the oven back
directly behind the control compartment. A grounding lug is provided at the rear
service entrance.
The EHS-AP can be purchased with a Cord & Plug kit (Part number is listed in the
parts portion of this manual.). This kit includes a 48” cord with a NEMA L15-30P
plug
Oven Voltage
The Lang Model EHS oven can be operated on 208, 240 (single or three phase), or
480-volt (three phase only) source. The Amp draw, KW rating, and phasing can be
found in the wiring diagram section of this manual.

INITIAL START UP
Pre-Power On
After the oven is installed and connected to power, prior to turning on, verify the
following:
•The door opens and closes freely.
•All racks are in the oven correctly.
•All packing materials have been removed from the inside of the oven.
Power On
Once oven has been turned on verify that the blower wheel is spinning freely in a
clockwise position and that the elements are heating properly.
Confirm that both thermostat knob and timer knob move freely and that the timer
beeps.
NOTICE During the first few hours of operation you may notice a small amount of
smoke coming off the oven, and a faint odor from the smoke. This is normal
for a new oven and will disappear after the first few hours of use.

OPERATION CONT’D
Hints & Suggestions
Convection ovens constantly circulate air over and around the product. This strips
away the thin layer of moisture and cool air from around the product allowing heat to
penetrate more quickly.
Cooking times can be shortened and cooking temperatures can be reduced.
To convert standard deck oven recipes, reduce the temperature 50 degrees and the time
by 25%. Make minor adjustments as necessary.
The lower the oven temperature the more even the bake.
Always weigh your product. This will give you a more consistent size, color and
quality.
Check the product near the end of the initial cooking.
Do not open the oven doors during baking as this will change the baking characteristics
of the oven and make it difficult to determine a final program.
If the product is overdone on the outside and underdone on the inside, reduce the
baking temperature.
If the product is pulling away from the edge of the pan, the temperature is too high or
the cooking time too long.
The convection is a mechanical piece of equipment. The same control settings will
always give the same results. If the results vary, problems may be because of product
preparation.
Loading
When loading and unloading the oven, stage products and racks so the oven doors are
opened for the least amount of time.
Be sure that racks are level within the oven.
Bent or warped pans can greatly affect the evenness of the cook or bake.
If using baker’s parchment, be sure the parchment does not blow over the product.
The will create an uneven bake.
Load each shelf evenly. Spaces should be maintained equally between the pan and
oven walls, front and back.
Do not overload pan’s this will create a uneven bake.
For best baking results, load the oven from the center out during random loading.
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.

MAINTENANCE & CLEANING
WARNING KEEP WATER AND SOLUTIONS OUT OF CONTROLS. NEVER SPRAY OR
HOSE CONTROL CONSOLE, ELECTRICAL CONNECTIONS, ETC.
CAUTION MOST CLEANERS ARE HARMFUL TO THE SKIN, EYES, MUCOUS
MEMBRANES AND CLOTHING. PRECAUTIONS SHOULD BE TAKEN TO
WEAR RUBBER GLOVES, GOGGLES OR FACE SHIELD AND PROTECTIVE
CLOTHING. CAREFULLY READ THE WARNING AND FOLLOW THE
DIRECTIONS ON THE LABEL OF THE CLEANER TO BE USED.
NOTICE Never leave a chlorine sanitizer in contact with stainless steel surfaces
longer than 10 minutes. Longer contact can cause corrosion.
Cleaning
•Always start with a cold oven.
•Always follow the cleaner manufacturer's instructions when using any cleaner.
•Care should be taken to prevent caustic cleaning compounds from coming in
contact with the blower wheel.
•Always apply these cleaners when the oven is cold and rub in the direction of the
metal's grain.
