This manual covers the following XLT Oven & AVI Hood models:

The first 2 digits of the model number after the dash represent the conveyor width and the

last two digits indicate the bake chamber length. The five x’s after those numbers represents the oven and hood configuration number. The “EL” designates electrically heated ovens. The ovens

may be used in a single, double, or triple stack configuration. All models have a single control box, which can be mounted on either the right-hand or left-hand side, and are heated by electric elements. All models can be configured for a split belt conveyor.

OVEN DESCRIPTION

Food product is placed on the stainless steel wire conveyor belt on one side of the oven. The conveyor then transports the food through the bake chamber at a user-controlled speed. This provides repeatable and uniform food cooking. The conveyors can be easily configured to move either left-to-right or right-to-left. A large center sandwich door allows the introduction or removal of food items for cooking at shorter times. Precise temperatures are user adjustable and maintained by a digital control. An easily removable front panel allows the full cleaning of the oven interior. All exposed oven surfaces both exterior and interior are stainless steel. The conveyor is a one piece design and is removed from the side which has the control box. No tools are required for disassembly and cleaning of the conveyor or oven interior. The oven itself is mounted on lockable swivel casters for easy moving and maintenance. Accessories such as extended conveyor shelves, base shelves, extended fronts, fire suppression components, and perforated crumb trays are available from XLT. In addition, moving equipment such as carts and lifting jacks are available to help install and move ovens. Please contact XLT Ovens or your Authorized Distributor for more information.

WARNING & SAFETY INFORMATION

XLT ovens can easily be moved and stacked with the proper lifting equipment. The use of XLT approved lifting equipment is highly recommended. Contact XLT for more information.

 These ovens are heavy & can tip or fall causing bodily injury.  NEVER place any part of your body beneath any oven that is suspended by the

lifting jacks. A crush hazard exists if the oven falls or slips.

 DO NOT place your hands on the lifting jack vertical pole beneath the jack’s

CAUTION

DANGER

winch. As the jack’s winch descends when you turn the jack handle, a pinch

point is created between the winch & the pole.

BE CAREFUL when rolling the oven on the cart, especially when going up or down ramps & over bumps. Leave the straps/banding on until the oven is near the assembly area.

 Make sure that the notch on tube of the winch assembly is aligned with the pin

in the tripod base as shown. These alignments are important and keep the jack aligned properly.

 Check for smooth operation. The cable should not be pinched and should pass

smoothly over the pulley on top of the pole assembly.

 Inspect cable prior to each use.  If cable is frayed or shows signs of excessive wear and tear, DO NOT USE until

cable is replaced.

 At a minimum replace the cable annually with wire rope that meets or exceeds

the jack manufacturer’s specifications.

 Do not exceed the stated capacity of the jack.

OVEN INSTALLATION

Physical Location & Spacing Requirements

These ovens are suitable for installation on either combustible or non-combustible floors, and adjacent to either combustible or non-combustible walls. The motor cover is designed to provide the proper clearance to the back of the oven. The minimum side clearances are 6in. / 150mm, measured from the end of the conveyor.

All installations must conform to local building and mechanical codes.

NOTE

Restraint

Because all ovens are equipped with casters, all installations must be configured with a restraint to limit the movement of the oven without depending on the electric power supply cord to limit the oven movement. One (1) restraint kit, which includes one (1) eye bolt, (1) stainless steel clip & a cable, is required for each oven stack, regardless if used on a single, double, or triple configuration. The clip should be installed in the lowest hole of the back wall on the control end of the lowest oven in the stack. The lag eye bolt must be installed into a structural member of a wall or the floor. It is the owner’s responsibility to ensure the restraint is installed correctly. Upon completion of performing any service or cleaning functions that require removal of the restraint, insure that it is correctly re-attached to the oven.

OVEN FIRE SUPPRESSION

The requirement for fire suppression systems vary by location and the authority having jurisdiction. If you are required to install fire suppression on your oven, a pre-assembled piping kit is available that utilizes pre-existing holes that simplify installation and future service.

This design has been tested and approved to successfully comply with fire suppression codes. It uses only two (2) nozzles per bake chamber, and allows crumb trays, chain guards, and all other accessories to be easily removed. The kit does not interfere with any operations or maintenance.

For fire suppression detailed information see manual XD-9011 Fire Suppression Installation for AVI Hoods and XLT Ovens.

OVEN VENTILATION REQUIREMENTS & GUIDELINES

Ventilation Requirements

A powered ventilation hood is required to remove heat and vapors. Some provision must be made to replenish the amount of air that is extracted from the building. The hood and HVAC installation must meet local building and mechanical codes. Requirements vary throughout the

country depending upon location. Proper ventilation is the oven owner’s responsibility. The AVI

Hood system is designed to meet all requirements for XLT ovens and it is our recommendation that this system be used.

Ventilation Guidelines

Obtain information from the authority having jurisdiction to determine the requirements for your installation. Your ventilation hood supplier and HVAC contractor should be contacted to provide guidance. An air balance test is highly recommended, performed by a licensed contractor. A properly engineered and installed ventilation hood and HVAC system will expedite approval, reduce all maintenance costs, and provide a more comfortable working environment. XLT also recommends that the operator switches for the ovens and the operator switch for the exhaust fan be interlocked so that the exhaust fan gets energized whenever the ovens are turned on. For more information, see the following links at xltovens.com: Kitchen Ventilation Design Guide 1 Kitchen Ventilation Design Guide 2 Kitchen Ventilation Design Guide 3 Kitchen Ventilation Design Guide 4

Ventilation Performance Test

After the oven and ventilation hood have been installed and are operating, a smoke candle

can be used to “see” if the heat and vapors are being completely extracted. The test procedure is

outlined below:

 The oven must be operating at 450º-500ºF / 232º-260ºC.  The conveyor must be turned off.  The ventilation hood exhaust fan must be turned on.  Put a smoke candle in a pan on the conveyor belt at the center of the oven.  Observe the smoke pattern coming out of the oven.  Repeat the smoke candle test for each oven, as well as when all ovens are operating.

The ventilation hood must capture all of the smoke from the oven.

After the exhaust fan has been adjusted to completely capture and contain the heat, there needs to be a corresponding amount of make up air (MUA) introduced into the building to offset the amount of air volume being removed. An air balance test can determine the proper amount of make-up air flow rates.

All ovens are tested at the factory for functional operation. Operation is verified and adjustments are made to ensure proper function. However, field conditions are sometimes different than factory conditions. It is necessary to have an authorized service technician verify operation and make field adjustments if needed.

The Oven Initial Start-Up Checklist, found at the end of this manual, must be completed (both sides) at time of installation, signed by the Customer and returned to XLT Ovens and the Authorized Distributor to initiate Warranty Policy.

If the Start-Up Checklist is not filled out completely and returned to XLT Ovens, then the Warranty will not be honored.

Start-up Procedure:

Ensure that all ovens have been installed in accordance with the I&O Manual and that all utilities are connected to the ovens in compliance with local building codes. A copy of the Start-up checklist is located at the end of this manual.

OVEN INITIAL START-UP

1. Fill out Step 1 on the checklist with all information and print legibly.

2. Place all control boxes in service position, remove all blue tags from inside all control boxes and connect switch to wire harness. Start each oven and complete form.

3. Complete Start-up checklist with owner signature and return to XLT.

OVEN CLEANING

Your XLT oven is constructed of stainless steel. Most commercial cleaning agents may be used safely on all stainless steel surfaces. Check application restrictions on product label prior to usage. Observe recommended precautionary and safety measures as dictated by the product manufacturer. Do not use caustic cleaner on the conveyor bearings. Do not use abrasive cleaners or abrasive pads as they can scratch stainless steel surfaces. Areas with heavy buildup should be sprayed and allowed to soak for up to 5 minutes prior to wiping clean. Always wipe with the “grain” of the surface to maintain appearance. Do not use caustic cleaners on the control panel and/or electronic components. Only use cleaners compatible with Lexan® on the face of the conveyor control. The most critical items to be cleaned are the filters on the cooling fans. The filters are held in place by the stainless steel fan guard/filter mounts and can be washed several times. Regular cleaning of the cooling filters is important to maintain air circulation within the control box. Depending upon store conditions, the filters should be cleaned weekly or as they get clogged with dust. Please contact XLT Ovens for replacement parts.
