Page 15: Oven Only Rough-In Specifications
Oven Only Rough-In Specifications The gas supply and the electrical supply are to be provided by the customer prior to instal- lation. The picture shows a typical utility rough-in for a triple stack oven. Preparing the utilities this way allows for an easy third deck addition if a double stack oven is initially installed. 6.00 [152] From back of oven to wall Utilities must be easily accessible when the ovens are in the installed position.
Page 16 Oven Only Rough-In Specifications FOR EACH OVEN: Electrical service for Standard Ovens must be 120VAC, 20 A, 60 Hz single phase circuits with ground. Electrical service for World Ovens must be 220/230/240VAC, 10 A, 50/60 Hz single phase circuits with ground. Electrical service for Australian Ovens must be 220/230/240 VAC, 10 A, 50Hz single phase and installed in accordance with the latest version of AS/NZS 3000 wiring rules.
Page 17: Oven Assembly
Oven Assembly WARNING & SAFETY INFORMATION XLT ovens can easily be moved and stacked with the proper lifting equipment. The use of lifting equipment is highly recommended.  These ovens are heavy and can tip or fall causing bodily injury.
Page 18 Oven Assembly Base Assembly - Single & Double Stack 1. Flip the oven base upside down on the floor. 2. For single and double-stack configurations, attach the four legs to the bottom of the base with the supplied 3/8" x 1" hex bolts, washers, and lock-washers. Do not fully tighten them at this time.
Page 19 Oven Assembly Prepare the Oven for Lifting 1. Remove the two conveyor opening flaps and thumbscrews from the oven. Set them aside for reinstallation later. 2. Install the lifting plates in place of the conveyor opening flaps using the same thumbscrews. If using an AVI Hood System, conveyor flaps are not needed.
Page 20 2. Insert the lifting pipe through the oven bake chamber. Make sure the pipe is centered. Top of Oven Front of Oven Lifting Pipe Jack Cart Bands Illustrations shown with XLT Oven on Cart, instructions also apply when oven is crate shipped.
Page 21 Oven Assembly Stacking the Ovens 1. Fully insert the lifting jacks into the lifting pipe.  Failure to engage properly can result in damage, injury, or death from a falling oven. WARNING 2. Raise the oven high enough to clear the cart or the skid. ...
Page 22 Oven Assembly Stacking the Ovens 8. Reinstall the conveyor opening flaps in each oven deck. A series of holes in the flaps allow adjustment for different heights of food product. 9. Control box heat shields need to be installed on any multi-deck installation. For xx70 models, they are required on both ends.
Page 23: Oven Installation
Physical Location & Spacing Requirements XLT 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 pro- vide the proper clearance to the back of the oven. The minimum side clearances are 6in. / 150mm, measured from the end of the conveyor.
Page 24 Oven Installation Gas Supply Requirements for Australian, Standard. & World Ovens 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, and ovens in operation at the same time. Add up all of the Btu/kw/MJ ratings to determine the total load.
Page 25 Oven Installation Restraint Because all ovens are equipped with casters, all installations must be configured with a re- straint to limit the movement of the oven without depending on the gas connector and quick- disconnect device or its associated piping, and the electric power supply cord to limit the oven movement.
Page 26 Fire Suppression The requirement for fire suppression systems vary by location and the authority having ju- risdiction. Contact XLT Ovens for fire suppression kit availability. Crumb trays and chain guards must be removable without disturbing fire suppression piping. Supply Line...
Page 27 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 rec- ommendation that this system be used.
Page 28 CAUTION 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 author- ized service technician verify operation and make field adjustments if needed.

Page 40: Oven Maintenance
Oven Maintenance The most critical item to be maintained is the filter on the Flow Path Pressure Generating fan. The filter is held in place by the stainless steel fan guard/filter mount and can be washed sev- eral times. Regular cleaning of the Flow Path Pressure Generating Fan filter is important to pro- vide combustion air and to maintain air circulation within the control box.
Page 41: Oven Troubleshooting
6. Check to see that the oven is fully assembled. All of the fingers must be properly installed. XLT Ovens has qualified customer service personnel that can provide assistance on any type of issue that you may experience. Customer Service can be contacted at 888-443-2751, 24 hours per day, 7 days per week.
Page 42 8. Raw ingredient temperature (frozen?) 9. Quantity of toppings XLT ovens can be configured to cook a wide variety of food items. This is accomplished by arranging the fingers to control the baking characteristics. Generally speaking, most cooking is a “bottom up” process. The hot air from the bottom row of fingers has to go through the conveyor (a distance of about 2”...
