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 re-
moval 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.
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 LP gas 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.
“-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 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.
All installations must conform to local building and mechanical codes. It is required that
the ovens be placed under a ventilation hood. The gas supply should have a gas meter and regula-
tor large enough to handle all of the gas appliances, such as the furnace, hot water heater, and ov-
ens, in operation at the same time. Add up all of the BTU / kw / MJ ratings to determine the total
load. (See Oven Specifications page for supply requirements).

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-
fect warranty.
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.
 A separate circuit breaker must be provided for each oven deck.
 Gas and electric connections must be accessible when the ovens are in the installed position.
 Electrical plugs and cords must meet all local code requirements.
Gas hose assemblies with quick disconnects for each oven deck will be installed at each valve.

OvenAssembly
XLT ovens can easily be moved and stacked with the proper lifting equipment. The use of
lifting equipment is highly recommended.
WARNING & SAFETY INFORMATION
Base Assembly - Triple Stack
1. Flip the oven base upside down on the floor.
2. For triple-stack configurations, attach the four casters directly to the base with the supplied
3/8" x 1" hex bolts, washers, and lock-washers.
3. Flip the base assembly over and ensure the insulation is placed properly.
 These ovens are heavy and 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 and the pole.
WARNING
BE CAREFUL when rolling the oven on the cart, especially when going up or down
ramps and over bumps. Leave the straps/banding on until the oven is near the assem-
bly area.
CAUTION

18
OvenAssembly
Leg Angle
Leg
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. Leave them slightly loose so that the rest of the components can be more easily assem-
bled.
3. Place the four leg angles on top of the legs as shown. All of the leg angle holes should line up
with the holes in the bottom of the legs. Place two (2) washers on each leg at the inner corner
holes. These 2 washers are approximately the same thickness as the leg angles, and will keep
the caster level.
4. Attach the four casters to the legs as shown. The leg angles and washers are sandwiched be-
tween the casters and the leg base plates.
5. Tighten all fasteners.
6. Flip the base assembly over and ensure the insulation is placed properly.

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.

Lifting Jack Setup
Each lifting jack consists of two (2) parts; the pole/winch assembly, and the tripod base.

2. Insert the lifting pipe through the oven bake chamber. Make sure the pipe is centered.
 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 NO 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.
WARNING
1. Place the bottom of the pole into the socket of the tripod base.
