Use the Oven Finger Arrangement Diagram to reassemble the fingers correctly. This example follows the finger arrangement for a Middleby 740 WOW oven:

1. Group Components by Code: Identify the engraved codes on the finger components and group the three parts for each finger:
   a. Finger Manifold
   b. Finger Inner Plate
   c. Finger Outer Plate

2. Position the Manifold: Place it upright and note the code engraved on its side.
3. Attach the Inner Plate:
   • Find the corresponding Inner Plate by matching the engraved code with the Finger Arrangement Guide.
   • Slide the Inner Plate into the Manifold. 

4. Attach the Outer Plate:
   • Locate the correct Outer Plate by validating its engraved code with the Finger Arrangement Guide.
   • Hold the Outer Plate securely with both hands and slide it onto the Manifold from the top.

Repeat these steps for all fingers, ensuring proper alignment and code matching to maintain the correct oven configuration.

Position the Full-Blank Plate:

• Slide the full-blank plate into the oven cavity’s top flange (rail).
• Ensure it is centred between the brackets, with tilted edges overlapping the adjacent fingers. This overlap prevents gaps critical for proper airflow and heat distribution.

Insert the Fingers:

• Refer to the Finger Arrangement Diagram to select the correct fingers.
• Using both hands, slide the back finger into place from the oven entrance.

Similarly, slide the front finger into place from the oven exit or the side with the control panel.

Insert the Half-Blank Plates:

• Slide the half-blank plates into the flange from the front and back of the oven.

Make sure the plates fully overlap the fingers, leaving no gaps, as illustrated in the diagram.

Installing the Bottom Fingers

Position the Fingers:

• Using the Finger Arrangement Diagram as a reference, select the appropriate fingers for the bottom.

With both hands, carefully slide each finger into the brackets, as shown in the diagram.

Complete the Installation:

• Install all four fingers in the bottom flange, ensuring they are evenly placed with no gaps to maintain consistent heat flow.

Following these steps and referring to the diagram for guidance, ensure the oven is correctly reassembled for optimal cooking performance.

The Middleby 740 WOW oven deck includes four plugs—two for the top and two for the bottom. Correct installation is crucial to avoid oven damage and prevent heat loss. This guide will help you differentiate and correctly install the plugs. Refer to the picture below for a visual comparison between the top and bottom plugs to ensure correct placement.

Bottom Plugs:

• These plugs are designed to support the weight of the conveyor belt assembly and frame.
• They can be identified by their distinctive upside-down “L” shape at the base.
• Use two hands and place the oven’s bottom plug into its position, as shown in the picture.
• Secure the plug using two fasteners. Tighten the fasteners by hand—ensuring they are snug but not overly tight.

Top Plugs:

• The top plugs are used to secure the oven eyebrows in place.
• They feature a 90-degree angle on each side for proper alignment and fit.
• Use two hands and place the oven’s bottom plug into its position, as shown in the picture.
• Secure the plug using two fasteners. Tighten the fasteners by hand—ensuring they are snug but not overly tight.

Note: First, insert and secure the conveyor frame before attaching the top plugs.

Note: This process requires two people for safe and efficient handling.

1. Position the Frame.
   • Unfold the conveyor belt frame on a flat surface
2. Place the Belt:
   • Lay the rolled conveyor belt on the flat surface at the end of the frame without sprockets.
3. Begin Feeding the Belt:
   • Unroll approximately 10 inches (25 cm) of the belt and feed it into the conveyor frame, sliding it under the driver shaft.
4. Guide the Belt:
   • Feed the belt between the two metal bars within the conveyor frame. Continue unrolling and sliding it forward along the frame and between the metal bars.
5. Position Over the Shafts:
   • When the belt reaches the driver shaft at the other end of the frame, slide it underneath and guide it to roll over the shafts.
6. Align the Belt Ends:
   • Bring the two ends of the belt close together, ensuring the master links remain intact and securely in place.
7. Prepare for Connection:
   • Fold the conveyor frame so the belt ends become loose and ready for connection.
8. Lock the Belt Ends:
   • Using only your hands, connect the two ends of the belt, as shown.
9. Secure the Master Links:
   • With long-nose pliers, carefully lock the master links in place.
   • Apply gentle pressure to avoid breaking or deforming the links. The belt’s loose tension should allow for easy locking without forcing the links.

Important Note: When reinstalling the belt, ensure that the bends of the hooks at both ends are facing toward the oven exit.

Note: This process requires two people to ensure safe and efficient handling.

1. Prepare the Frame:
   • Fold the conveyor belt frame and move it to the oven exit side or the side with the motor sprockets.
2. Lift and Partially Unfold:
   • Each person should hold the frame from opposite sides, lift it carefully, and partially unfold it.
3. Position on the Rails:
   • Align the bottom metal bars of the conveyor frame with the rails inside the oven cavity and place the frame gently on the rails.
4. Slide the Frame Into the Cavity:
   • Gently slide the frame halfway into the oven cavity along the rails, ensuring you avoid contact with or damage to the motor sprockets.
5. Fully Unfold the Frame:
   • Once the frame is partially inside, fully unfold it. Take care to keep your hands clear of the hinges during this step.
6. Distribute the Weight:
   • At this stage, the frame’s weight will be supported by the rails. One person should move to the back of the oven while the other remains at the front.
   • The person at the front continues pushing the frame inward while the person at the back pulls it gently until the frame rests securely on the oven’s bottom plugs.
7. Secure the Frame:
   • Verify that the frame is stable, properly aligned, and does not shift or move.

1. Position the Cover:
   • Slide the chain and sprockets cover into place from the side, as illustrated in the accompanying picture.
2. Align the Screws:
   • Push the cover over the screws so the screw heads pass through the larger holes.
3. Secure the Cover:
   • Slide the cover downward to align it securely in position.
4. Tighten the Screws:
   • Use a flathead screwdriver to tighten the screws by turning them clockwise. Ensure they are snug but not overtightened.

Note: Oven eyebrows are essential for maintaining consistent oven temperatures. They must be installed at the correct height. In most Papa John’s restaurants, the gap between the oven eyebrows and the conveyor belt should not exceed 2.5 inches (6 cm). Refer to the Oven Eyebrows section of this guide for additional details.

1. Position the Eyebrows:
   • Align the oven eyebrows on the top plugs, ensuring the screws pass through the third hole from the top.
2. Secure with Fasteners:
   • Using your hands, attach the eyebrows firmly with the fasteners.
3. Check for Stability:
   • Make sure the eyebrows are secure, but avoid overtightening the fasteners, which could cause damage.
   • 

Proper belt tension is crucial for maintaining optimal oven performance and safety. Over time, the conveyor belt may loosen with regular use, leading to issues such as:

• Increased cooking time compared to the control display settings.
• Damage risks, including tangling with other oven components like crumb trays or metal bars, potentially causing permanent damage to the oven motor.

Key Requirements:

• The recommended belt tolerance is 1 inch (2.5 cm).
• Always ensure the conveyor belt is cool before adjusting the tension. Never attempt to adjust a hot belt.

Steps to Adjust Belt Tension

1. Check Belt Tension:
   • With the conveyor assembly inside the oven, stand at one end and lift the belt up through the oven chamber opening.
   • The belt should not lift over 1 inch (2.5 cm).

1. Adjust the Tension Screw:

Locate the tension screws on the entrance end of the oven. Adjust it to achieve the proper deflection range of 1 inch (2.5 cm).

Note: If the correct tension cannot be achieved with the adjustment screws, do not use the oven, and please get in touch with your approved oven maintenance service provider.
