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 ovens may be used in a single, double, or triple oven stack
configuration. All ovens are gas-fired & are available in Natural gas or LP gas models (Electric
ovens are also available). The 3270 & 3870 models have two burners, one on each side, & have
two control boxes. All other models have only a single burner with a single control box that can
be supplied on either end. 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 GAS REQUIREMENTS
Gas Supply Requirements for Australian, Standard. & World Ovens
All installations must conform to local building & mechanical codes.
NOTE
1. The gas supply shall have a gas meter & regulator large enough to handle ALL of the gas ap-
pliances, such as the furnace, water heater, & ovens in operation at the same time. Add up all
of the Btu/kw/MJ ratings to determine the total load.
2. The gas supply shall have a separate gas meter and gas pressure regulator for each occupant.
Installations in multiple occupancy buildings, (strip malls) shall not share gas meters and regulators with other occupants.
3. Gas hose assemblies with quick disconnects for each oven deck will be installed at each valve.
4. A sediment trap shall be installed downstream of the equipment shutoff valve as close to the
inlet of the appliance as practical at the time of appliance installation. The sediment trap shall
be either a tee fitting with a capped nipple in the bottom outlet as illustrated, and in accordance
with ANSI Z223.1-2012 and NFPA 54-2012 National Fuel Gas Code, section 9.6.7.
5. The composition of gases varies greatly from time to time and from place to place. For this
reason, the material used for the gas lines shall be steel or malleable iron, not copper. ANSI
Z83.11-2006 CSA 1.8-2006 Gas Food Service Equipment states: “Copper tubing or semi rigid
tubing with internal copper layering, whether internally tinned or not, shall not be used for con-
veying gases.” ANSI Z223.1 NFPA 54 National Fuel Gas Code states: “Copper and brass tub-
ing shall not be used if the gas contains more than an average of 0.3 grains of hydrogen sulfide
per 100 scf of gas (0,7 mg/100L).”
Do not use Teflon tape on gas line connections as this can possibly cause gas valve
malfunction or plugging of orifices from shreds of tape. Use of Teflon tape may af-

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

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 or
gas hose 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 mem-
ber of a wall or the floor. It is the owner’s responsibility to ensure the restraint is installed cor-
rectly.
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.
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
27
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.
Technical Support US: 888-443-2751 Technical Support INTL: 316-943-2751
28
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.
