This manual covers the following XLT Oven & AVI Hood models:
The first 2 digits of the model number represent the conveyor width and the last two digits
indicate the bake chamber length. 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.
DESCRIPTIONS
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, cool 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.

OVEN ASSEMBLY
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
WARNING
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.

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.
21
A flexible hose that connects the oven to the rest of the fire suppression system is also
available. This allows easy movement of the oven(s) for cleaning and maintenance.

OVEN VENTILATION REQUIREMENTS & GUIDELINES
23
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 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.

24
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.

OVEN CLEANING
27
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 wip-
ing clean. Always wipe with the “grain” of the surface to maintain appearance.
The most critical item to be cleaned is the filter on the cooling fans. The filters are held in
place by the stainless steel fan guard/filter mount & 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, this filter should be cleaned weekly or as it gets clogged with dust. Please
contact XLT Ovens for replacement parts.
