IMPINGER® I DIGITAL ADVANTAGE SERIES

SINGLE BELT CONVEYORIZED GAS FIRED OVEN

FEATURES

• AIR IMPINGEMENT uses hot air under pressure
which surrounds food with small jets of hot air.
This allows for rapid heating, cooking, baking and
crisping of foods, two to four times faster than
conventional ovens, depending on food product
cooked.

• Uniform heating/cooking of food products offers a
wide tolerance for rapid baking at a variety of
temperatures.

• Variable speed Continuous Cook Platform moves
products through the oven one after another,
improving product flow during cooking and virtually
eliminating labor.

• Safety of conveyorized product movement is a
definite advantage over batch type ovens, as it
eliminates the need for constant tending.

• Oven has one self-contained heating system.

• Customer specific air fingers on top and bottom
allow for the heat to be adjusted and controlled by
zoning.

DIGITAL CONTROLS

The 4-button digital microprocessor control panel is
located at the back right of the oven and has power
on-off switch, temperature controls, and conveyor
speed control. The LED readout displays actual
cavity temperature in degrees (F° or C°), conveyor
belt speed, thermostat indicator light, and
diagnostic messages for easy troubleshooting. All
settings are automatically locked out to eliminate
accidental changes to desired settings. All ovens
are digitally calibrated at the factory, reducing the
need for periodic calibration.

GENERAL

Gas Fired Baking/Finishing Oven is self-contained,
conveyorized and stackable up to 2 high. Temperature is
adjustable from 250°F (121°C) to 600°F (316°). Conveyor
speed is adjustable from 1 minute to 30 minutes cooking
time. Front door has access opening with an optional
see-through window to allow product to be placed on the
moving conveyor inside the baking chamber when a shorter
cook cycle is desired. Air distribution fingers are removable
through the front door for easy cleaning. Crumb pans are
located below the conveyor belt outside the baking cham­ber.

CONSTRUCTION

Exterior is fabricated from No.4 finish stainless steel. The
air distribution system consists of an axial type fan
powered by 1/3 hp, AC Motor. The heated air is forced
through eight (8) distribution fingers located in the bak­ing chamber with four (4) above the conveyor belt and
four (4) below. Each finger has required number of holes
to create the air impingement effect on the food product
passing through the baking chamber on the conveyor
belt. The conveyor belt is a flexible stainless steel design
with capacity for 32” (813mm) wide product and a travel
distance of 72” (1829mm), of which 35 ” (908mm) is in
the baking chamber. The indirect drive conveyor system
is powered by an AC motor with an external reversing
switch on the rear of the motor control box for installations
requiring opposite belt travel.

GAS SERVICE: Gas Control system has a manual shut-off valve, internal pressure regulator (factory preset at 3 ” water

column/. 87 kPa or 8.70 mbar for Natural Gas, 10” water column/2.48 kPa or 24.87 mbar for LP gas), and an electric sole­noid operated main gas valve. Heat is supplied by one (1) power burner rated at 120,000 BTU/Hr. (126MJ) with electronic
ignition. Natural gas requires 7” WC/1.7 kPa or 17.4 mbar inlet with maximum allowable of 14.5” WC/3.6 kPa or 36.05 mbar.
LP gas requires 11” WC/2.7 kPa or 27.36 mbar inlet with maximum allowable of 14.5” WC/3.6 kPa or 36.05 mbar. Gas line
from meter to ovens should be sufficient size to insure full volume flow of gas to ovens. AGA/CGA design approved flexible
connection to each oven must be ” NPT and length must not exceed 6 ft. (1829mm).

ELECTRICAL SERVICE: Each oven requires standard 120V service and comes with a factory installed cord with NEMA 5-15
plug. It is recommended that a separate 20 amp - 1 pole circuit breaker be provided for each oven deck.

VENTILATION: Ventilation is required. Local codes prevail. These are the “authority having jurisdiction” as stated by the
National Fire Protection Association, Inc. in NFPA 96-1994. Consult Model 1450, 1451 Installation and Operations Manual for
ventilation recommendations.

SPACING: The oven must have 5” (127mm) of clearance from combustible surfaces and 24” (610mm) clearance on both

SINGLE BELT CONVEYORIZED GAS FIRED OVEN

sides from other cooking equipment. A permanently installed oven requires approximately 11ft. (3553mm) of clearance overall
to allow for removal of the conveyor and protective guards for cleaning. The conveyor is removed from the control side of the
oven.

IMPINGER

WARRANTY: All new Impinger® ovens come with a one year parts/labor warranty. Defective parts of the original equipment

on all installed ovens are warranted for one year from the date of “START-UP/CHECK-OUT.”
