receipt & call the carrier to make a freight damage claim within 24 hours of receipt. Failure to
make a damage claim within the first 24 hours may void the opportunity to have the claim re-

10 OVEN DESCRIPTION
This manual covers the following XLT Oven & Hood models:
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 with a simple programming change. A large optional center
sandwich door allows the introduction of food items for cooking at shorter times. Precise tempera-
tures 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 conveyor shelves, base shelves, extended fronts, fire suppression com-
ponents, 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 or your
Authorized Distributor for more information.
OVEN DESCRIPTION
The first two (2) digits of the model number after the dash represent the conveyor width
and the last two digits indicate the bake chamber length. For example, the X3H-3255-xxxx models
would have a bake chamber with the width (A in image above) of 32 inches and the length (B in
the image above) of 55 inches. The five (5) x’s after those numbers represents the oven and hood
configuration number. The HP after the five (5) x’s represents the faster baking high performance
ovens. All models have only a single burner with a single control box that can be supplied on ei-
ther end. The ovens may be used in a single, double, triple or quad oven stack configuration. All
ovens are gas-fired & are available in Natural gas or Liquid Petroleum gas models (Electric ovens
are also available in a variety of sizes). All models can be configured for a split belt conveyor.

The BTU readings listed are maximums that could be reached while climbing to the set
point temperature. Once set point is reached the BTU/HR will lower. Readings will
vary as oven capacity changes during operation.

Gas Supply Requirements for All Ovens
1. The gas supply shall have a gas meter and regulator large enough to handle ALL of the gas
appliances, 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 regu-
lators 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 a tee fitting with a capped nipple in the bottom outlet as illustrated ( Pg. #20), and in accord-
ance with ANSI Z223.1-2012 and NFPA 54-2012 National Fuel Gas Code, section 9.6.7.
5. A sediment trap shall be installed on the rear of the oven control box before the gas hose. The
sediment trap shall be a tee fitting with a capped nipple in the bottom outlet as illustrated ( Pg.
#20), and in accordance with ANSI Z223.1-2012 and NFPA 54-2012 National Fuel Gas Code,
section 9.6.7.
6. The composition of gases varies greatly from time to time and from place to place. For this rea-
son, the material used for the gas lines shall be steel or malleable iron, not copper. ANSI
Z83.11-2016 CSA 1.8-2016 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).”
All installations must conform to local building & mechanical codes.
NOTE
Do not use Teflon tape on gas line connections as this can cause gas valve malfunc-
tion or plugging of orifices from shreds of tape.
