XLT Ovens are certified to the following Standards:
“-AE” indicates Australian Export configuration, certified to AGA AS 4563.
“-S” indicates Standard configuration, certified to ANSI Z83.11/CSA 1.8 & ANSI/NSF 4.
“-W” indicates World configuration, certified to CE GAD 90/396/EEC & BS EN 203-1.

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. A single or double configuration can be upgraded by adding additional decks up to
the maximum of three. All ovens are gas-fired and are available in Natural gas or LPgas models
(Electric ovens are also available). The 3270 and 3870 models have two burners, one on each side,
and 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.
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. Temperatures up to 550º F or 288º C inside the
oven are achieved by means of a user-adjustable digital control.
Oven Description
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 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 and hoods. Please contact XLT or your designated representative for more
information.

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 gas connector and quickdisconnect device or its associated piping, and the electric power supply cord to limit the oven
movement. One (1) restraint kit, which includes two (2) eye bolts and a cable, is required for each
oven stack, regardless if used on a single, double, or triple configuration. The machine eye bolt
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.
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. In Australia, install the restraint cable in accordance with AS 5601, latest version.

Ventilation Requirements & Guidelines
27
Ventilation Requirements
Most gas burning appliances produce CO (carbon monoxide), a poison. CO and heat must
be vented to the outside. A powered ventilation hood is required to remove these. The hood and
HVAC installation must meet local building and mechanical codes. In Australia, a ventilation
hood should be installed in accordance with AS5601 Gas Installation. Requirements vary through-
out the country depending on the location by city. Proper ventilation is the oven owner’s responsi-
bility. The AVI Hood system is designed to meet all requirements on 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 oven maintenance cost, and provide a more comfortable working environment.
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 products of combustion are being properly exhausted. Smoke
candles can be purchased through HVAC contractors. 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.
The ventilation hood must capture all of the smoke from the oven. An air balance test can
help determine the proper amount of exhaust and make-up air flow rates.
Oven & Hood Interlock
An interlock system between the oven and hood is highly recommended and is required in
some jurisdictions. AVI hoods have this feature.
28
Ventilation Requirements & Guidelines
Non-AVI Hood Interlock
The following is a recommended method of providing an interlock system (if required),
between the exhaust fan and ovens. The circuit shown will stop the ovens from operating if the
exhaust fan fails and also prevent the ovens from starting if the exhaust fan is not first operating. It
is recommended that the fan interlock switch be located on the exhaust fan itself rather than the
motor to prevent a false run signal in the case of a broken fan drive belt. It is the customer’s re-
sponsibility to have the interlock system installed by a licensed electrician and that it meets all required local codes.
Always use the proper oven shut down procedure for turning ovens off. Do not
turn off the exhaust fan until cool down sequence on oven is completed. The use
of the exhaust fan control to shut off ovens manually may void the warranty on

ovens.
Oven Initial Start-Up
All XLT ovens are test-fired at the factory. Operation is verified, and adjustments are
made to ensure proper function. However, field conditions are sometimes different than factory
conditions, such as voltage and fuel pressure. These variables make it necessary to have an authorized service technician verify operation and make field adjustments if needed. The following
items must be checked and verified to meet the specifications and requirements stated in this manual prior to the oven being commissioned:
