SPACING

The oven must have 5 inches (127 mm) of clearance from combustible surfaces. In case other equipment is

located on the left or right side of oven, a minimum clearance of 24 inches (609 mm) is required from that

equipment.

FOR ALL OVENS: A 24-inch (609 mm) clearance at the rear of the oven must be obtainable for service access.

NOTE: Do not install these ovens in any area with an ambient temperature in excess of 95° F / 35° C. Doing

so will cause damage to the unit.

VENTILATION

A VENT IS REQUIRED: Local codes prevail. These are the “authority having jurisdiction” as stated by the

NATIONAL FIRE PROTECTION ASSOCIATION, INC. in NFPA 96-1994. For further ventilation information, see

below.

MASSACHUSETTS: In compliance with NFPA 54 Section 10.3.5.2, this unit must be installed with a ventilation

hood interlock that prevents the unit from operating when the ventilation hood is off.

VENTILATION & AMBIENT TEMPERATURE GUIDELINES

A ventilation hood is required to remove heat and cooking odors. For gas ovens, a ventilation hood is also required

to remove the products of combustion. The hood and HVAC installation must meet local codes to gain approval by

the authority having jurisdiction. Requirements may vary throughout the country depending on the location by city,

county, and state. Obtain information from the authority having jurisdiction to determine the requirements for your

installation. Obtain information and review copies of codes or documents that will be used to inspect and approve

your installation. Your ventilation hood supplier and HVAC contractor should be contacted to provide guidance. A

properly engineered and installed ventilation hood and HVAC system will expedite approval and reduce oven

maintenance costs. Proper ventilation is the oven owner’s responsibility.

The ventilation hood must operate in harmony with the building HVAC system. It typically requires between 2800

and 3400 CFM exhaust. (The “Efficiency” of various hood designs makes it necessary to specify such a wide range

of ventilator CFM.) Make up air must be supplied by either a hood design or the HVAC system. This will vary with

hoods from various manufacturers.

CAUTION: Prevent airflow through the cooking tunnel. Air must NOT be directed onto the oven front or at

side of cooking area or rear of oven.

Performance will be evaluated during Start-up Checkout by conducting a smoke candle test. The hood must

capture all smoke from the oven. This is required to assure proper performance of the oven and to eliminate

additional service calls that occur when ambient temperatures are too high. In all cases, the ambient temperature

around the oven must be less than 95° F / 35° C when the oven is operating. In certain localities, other chemical or

gaseous methods of detecting adequate capture will be the requirement to meet the local code authority.

The following diagram shows a typical installation and is intended to be a guideline. It is not a rigid specification.

Hood dimensions and the positioning of the hood over the oven will vary with hood manufacturers.

NOTE: Lincoln can provide oven specification sheets that show the dimensions of the oven, KW or BTU ratings and

other information that will be useful to both the ventilation hood supplier and the HVAC contractor.

CAUTION:

OVEN MUST BE OPERATED ON APPROVED BASIS ONLY.

INSTALLATION OVERVIEW

Familiarize yourself with the installation process as outlined in the manual and note the unique requirements of your

particular model. Select electricians and plumbers who have experience installing conveyor ovens and food

service equipment. For installation in the state of Massachusetts: Installation of this oven must be performed by a

licensed plumber or gas fitter. Conduct a site visit several days before the installation is scheduled. Utilities should

be installed prior to installation. The following is an overview of the installation process:

1. Read the manual thoroughly.

2. Make sure all electrical, gas, and ventilation utilities are adequately sized and in place well before the oven

arrives.

3. Inspect the oven and crates for freight damage upon arrival. Assemble the oven on its base near the area

of intended usage and level the unit. Remove all combustibles and obstructions from the area.

4. Have your qualified installer make all gas connections per national and local building codes. Provide

adequate clearance to access the gas shut-off valve. Check for leaks!

5. Have your electrician make all electrical connections per national and local codes. Provide adequate

clearance to access the electrical plug by a fixed electrical connection in front of the appliance. It is required

to use an all-pole switch having a contact separation of at least 3 mm in all poles.

6. Install both restraint devices and make sure they guards against transmission of strain to all utility

connections.

7. Have a factory-authorized technician inspect the installation and perform the initial start-up. The installation

Report should be completed by the start-up service technician and signed by the technician and customer

representative. Lincoln will not honor warranty claims unless the completed and signed installation report is

received (see warranty section for more information).

8. Test the exhaust hood using a smoke candle test to determine the amount of combustion products removed.

After the unit is assembles, the plumber and the electrician should be able to make their necessary connections.**

Roll the unit into position. Do not restrict airflow to the bottom of the mechanical compartment or louvers. Keep

louvers and bottom of oven clean and free of restrictions. Make sure enough space is allowed around the unit for

maintenance and service access. Do not block access to the manual gas shutoff valve.

For an appliance equipped with casters, the installation shall be made with a connector that complies with the

Standard for Connectors for Moveable Gas Appliances, ANSI Z21.69 • CSA 6.16 latest version, and a quick-

disconnect device that complies with the Standard for Quick-Disconnect Devices for Use With Gas Fuel, ANSI

Z21.41 • CSA 6.9 latest version. Adequate means must be provided to limit the movement of the appliance without

depending on the connector and the quick-disconnect device or its associated piping to limit the appliance

movement.

Install both restraints and make sure they limit the movement of the oven. One end of the restraint should connect

to a stud, post or concrete wall in which is strong enough to hold the weight of the oven whenever it is moved. The

other end of the restraint should be connected to an eyelet located on the bottom of the base near the rear casters.

The restraints must guard against transmission of strain to all utility connections.

** For installation in the state of Massachusetts, installation of this oven must be performed by a licensed plumber

or gas fitter.

The following items will be needed to complete installation of the Lincoln Tandem Oven.

• One (1) Genie Lift with extension forks.

• Two (2) Dolly Carts

• Two (2) Ratchet Straps (15’ or longer)

• Two (2) Pipe Clamps – (8’ or longer)

• Four (4) wood posts (4”x4”) that are 4’ in length

• “General Use” tools typical with large conveyor oven installations (to include 5/16” Allen Wrench for caster bolts

and 11/64” drill bit).

1. Place the two stand bases side-by-side in the position the ovens will be installed. While keeping them in

the same position, flip each base upside-down.

2. Attach Stand Joining Plate and Casters to the middle-front and middle-back of the combined base. The

Stand Joining Plate is what combines the two individual bases into one complete base. It is important that

the free end (side without caster) of the joining plates are not

tightened down completely. Some “give” is

necessary so that the two individual bases can slide back together after ovens are installed.

NOTE: Be sure to leave an approximate

gap of 3/8” between the two stands. The

Stand Joining Plates have slots that will

allow the bases to slide together later in

the installation process. DO NOT

place

the two individual stands flush together!

IMPORTANT:

IT IS NECESSARY THAT THE CASTERS ARE OFFSET FROM EACH OTHER

ONCE INSTALLED. ALLEN CAP HEAD BOLTS AND STAR WASHERS ARE

USED TO MOUNT THE CASTER. LARGE FLAT WASHERS ARE ADDED TO

THE FREE END.

!

IMPORTANT:

REMOVE PROTECTIVE LASER PAPER FROM UNITS PRIOR TO

INSTALLATION. THE WHITE LASER PAPER IS USED TO PROTECT THE

PIECES DURING SHIPPING AND SHOULD BE REMOVED PRIOR TO THE

INSTALLATION OF TANDEM UNITS.
