GAS SUPPLY

The serial plate indicates the type of gas the unit is equipped to burn. All equipment is adjusted at the

factory. Check type of gas on serial plate.

These models are design-certified for operation on natural or propane gases. For natural gas, the regulator

is set to deliver a 4" W.C. pressure to the manifold. For propane gas, it is set to deliver 10" W.C.

If applicable, the vent line from the gas appliance pressure regulator shall be installed to the outdoors in

accordance with local codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI

Z223.1, Natural Gas Installation Code, CAN/CGA-B149.1, or the Propane Installation Code CAN/CGA-

B149.2, as applicable.

This appliance should be connected ONLY to the type of gas for which it is quipped.

A 3/4" NPT line is provided at the rear for the gas connection. An adequate gas supply is imperative.

Undersized or low pressure lines will restrict the volume of gas required for satisfactory performance.

Fluctuations of more than 25% on natural gas or 10% on propane gas will create problems and affect

burner operating characteristics.

An adequate gas supply line to the unit should be no smaller than the inside diameter of the pipe from the

unit to which it is connected.

Purge the supply line to clean out dust, dirt, or other foreign matter before connecting the line to the unit.

All pipe joints and connections must be tested thoroughly for gas leaks. Use only soapy water for testing on

all gases. NEVER use an open flame to check for gas leaks. All connections must be checked for leaks

after the unit has been put into operation. Test pressure should not exceed 1/4" W.C.

For conversion to LP gas see the conversion instruction (Page.29).

MINIMUM CLEARANCES

!WARNING

There must be adequate clearance between the left side of the ovens and combustible construction.

Minimum Clearance from

Combustible

Construction

Minimum Clearance from

Non-Combustible

Construction

Back

Right Side

Left Side

Adequate clearance must be provided in the aisle to allow the doors to open sufficiently to permit the

removal of the racks and for serviceability.

Although no clearance is required behind the motor on the rear of the oven, care must be taken to

provide adequate air circulation to prevent the motor from overheating.

Do not locate the oven adjacent to any high heat or grease-producing piece of equipment, such as a

range top, griddle, fryer, etc., that could allow radiant heat to raise the exterior temperature of the

oven above 130°F (54°C). DO NOT MOUNT ABOVE OTHER COOKING EQUIPMENT.

VENTILATION

!WARNING

Improper ventilation can result in personal injury or death. Ventilation which fails to properly remove

flue products can cause headaches, drowsiness, nausea, or could result in death.

All units must be installed in such a manner that the flow of combustion and ventilation air are not

obstructed. Provisions for adequate air supply must be provided. Do not obstruct the front or rear of

the unit as combustion air enters through these areas.

Be sure to inspect and clean the ventilation system according to the ventilation equipment

manufacturer’s instructions.

NOTICE

Proper ventilation is the owner’s responsibility. Any problem due to improper ventilation will not be

covered by the warranty.

If a ventilation canopy is used, it is recommended that a canopy extend 6" past the appliance and that

the bottom edge be located 6'6" from the floor. Filters should be installed at an angle of 45° or more from

the horizontal. This position prevents dripping grease and facilitates collecting the run-off grease in a

drip pan, unusually installed with a filter.

If an exhaust fan is used, it should be installed at least 2" above the flue opening at the top of the unit. A

strong exhaust fan tends to create a vacuum in the room and may interfere with burner performance.

Fresh air openings approximately equal to the fan area will relieve such a vacuum. In case of

unsatisfactory performance on any appliance, check the appliance with the exhaust fan in the “OFF”

position. Do this only long enough to check equipment performance. Then turn the exhaust fan back on

and let it run to remove any exhaust that may have accumulated during the test.

If the oven flue is connected directly to an outside flue, a CSA International design certified down draft

diverter must be installed at the flue outlet of the oven and connected to the outside flue.

INSTALLATION

NOTICE

These installation procedures must be followed by qualified personnel or warranty will be void.

Local codes regarding installation vary greatly from one area to another. The National Fire Protection

Association, Inc. states in its NFPA 96 latest edition that local codes are the “authority having jurisdiction”

when it comes to installation requirements for equipment. Therefore, installations should comply with all

local codes.

The installation must conform with local codes, or in the absence of local codes, with the National

Fuel Gas Code, ANSI Z223.1, Natural Gas Installation Code, CAN/CGA-B149.1, or the Propane

Installation Code CAN/CGA-B149.2, as applicable, including:

1. The 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 psi (3.45

kPa).

2. 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 piping system at test pressures equal to

or less than 1/2 psi (3.45 kPa).

Step 1: Unpacking

IMMEDIATELY INSPECT FOR SHIPPING DAMAGE

All containers should be examined for damage before and during unloading. The freight carrier has

assumed responsibility for its safe transit and delivery. If damaged equipment is received, either apparent

or concealed, a claim must be made with the delivering carrier.

Apparent damage or loss must be noted on the freight bill at the time of delivery. The freight bill must then

be signed by the carrier representative (Driver). If the bill is not signed, the carrier may refuse the claim.

The carrier can supply the necessary forms.

A request for inspection must be made to the carrier within 5 days if there is concealed damage or loss that

is not apparent until after the equipment is uncrated. The carrier should arrange an inspection. Be certain to

hold all contents plus all packing material.

1. Cut banding straps and remove packing material.

2. Cut banding strap holding oven to wooden skid.

Step 2: Installation of Legs on Single-Deck Ovens (For Stacking kit, refer to instructions

included with kit)

1. Raise oven sufficiently to allow clearance for the legs to be attached. Use of a lift truck or other mechanical

lifting means is recommended. For safety, “shore up” and support the oven with an adequate blocking

arrangement strong enough to support the load. (If it is absolutely necessary to rest the oven on its side,

rest it on its left side.)

2. Attach the legs to the bottom corners of the oven using the provided machine screws and lock washers.

Each leg is secured by 3 screws. The mounting holes are pre-drilled and threaded.

3. Lower the oven gently onto a level surface. Never drop or allow the oven to fall.

4. Make sure that the oven is level.

5. Install required cable restraint connecting oven to wall.

Step 3: Installation of Restraint (Only for Ovens with Casters)

NOTICE

When this appliance is installed with casters, it must be installed with the caster supplied, a

connector complying with either ANSI Z21.69 or CAN/CGA-6.16 and a quick-disconnect

device complying with either ANSI Z21.41 or CAN1-6.9. It must be installed with a restraining

means to guard against transmission of strain to the connector, as specified in the appliance

manufacturer’s installation instructions.

!WARNING

To avoid accidental gas disconnection and potential explosion:

If disconnection of this restraint is necessary to move the appliance for cleaning, etc., reconnect it

when the appliance is moved to its originally installed position.
