II. PRINCIPLE OF AIR FLOW
Thefan-styleblowerdrawsairintotheovenplenumwhere
itisheated.Theblowerthenpushesthehotairthroughthe
air fingers into the baking chamber. Each air finger
containsaninnerplateandouterplatethatformthehotair

food product rides. Air is then pulled back into the blower
and the process continues. The curving, black arrows of
Figure 1-4 show this air flow.
PS536ES-Series Oven is light in color: To reflect more
heat back onto the food product.
Convection: Thispathhastodowithmovingavolumeof

air. An industrial application of this principle is to incorpo-
rate a fan to force the hot air movement, which in turn
increases the heat transfer to the food product.
EachPS536ES-SeriesOvenhasalargefan-styleblower
to move the hot air through the air fingers and onto the
product to cook/bake the food product most efficiently.
A. Heat Transfer and How It Works
1. Heat constantly moves from a warm object to a cold
object. Heat moves using three different paths: Conduc-
tion; Radiation; and Convection.
2. Temperature is the intensity of heat at the point where
it is sensed. As discussed above, heat flows by conduc-
tion,radiationandconvection.Thespeedatwhichtheheat
flowsisdeterminedbythetemperaturedifferencebetween
the oven and the food product. The larger the difference,
the faster the heat flows to the item that is being baked.
Conduction: This path utilizes surface-to-surface con-
tact. The pizza dough in contact with the pan is a good
example of conduction.
Radiation: Thispathhastodowithobjectsradiatingheat.
Dark objects absorb heat whereas light or shiny objects
reflect more heat. This is the reason that the inside of a

A. Conveyor Motor and Conveyor Belt
The conveyor belt is driven by a variable-speed electric
motor(Figure1-7)operatingthroughagearreducer. The
motor speed is controlled by a digital control. The stain-

ratesrangingfrom3minutesto30minutes;thisisthetime

B. Blower Fan
The blower fan is located at the rear of the oven. This
blower forces heated air through the air fingers. The
BLOWER/Heat switch must be set to “ON” or “I” for oven
warmupandbaking.
C.ElectricHeaters
There is one heater element mounted on the inside of the
left panel. The element is connected to an electrical
control which is energized by the temperature controller.
If the pilot flame does not light or a loss of flame occurs,
the main gas valve closes.
The main burner gas is extinguished when the HEAT
switch is set to “OFF” or “O”.

II. VENTILATION GUIDELINES
VENTILATION HOOD
A mechanically driven ventilation system is required for
the PS536ES Series Middleby Marshall conveyorized
electricovens.Theminimumhoodcanopydimensionsare
outlinedbelow.
The rate of air flow exhausted through the ventilation
system is generally between 1400 and 2500 cu. ft./min.
(40 and 70 m3/min), but may vary depending on the oven
configuration and hood design. To avoid a negative
pressure condition in the kitchen area, return air must be
brought back to replenish the air that was exhausted. A
negative pressure in the kitchen can cause heat related
problems to the oven components as if there were no
ventilation at all. The best method of supplying return air
is through the heating, ventilation and air conditioning
system. Throughtheysystem,theaircanbetemperature
controlled for summer and winter. Return air can be
broughtindirectlyfromoutsidethebuilding,butdetrimen-
talaffectscanresultfromeitherextremeseasonalhotand
cold temperature from the outdoors.
Local codes and conditions vary greatly from one area to
another and must be complied with. Following are the
suggested requirements for good ventilation. Please re-
member these are recommendations or guidelines, you
may have a special condition or problem that will require
theservicesofaventilationengineerorspecialist. Proper
ventilation is the oven owner’s responsibility. Improper
ventilation can inhibit oven performance. It is recom-
mendedthattheventilationandductworkbecheckedout

III. ELECTRICAL CONNECTION
INFORMATION FOR PS536ES-SERIES
OVENS.
IV. ELECTRIC SUPPLY FOR
ELECTRICALLY HEATED OVENS
Power requirements for electrically heated ovens are
usually208-240VAC,3-phase,4-wire(3‘hot’,1ground),
although ovens built for export can have power require-
ments of 380VAC and 480VAC. (These ovens have a 5-
wire system.) A 2″ (51mm) diameter cutout/hole in the
back of the machinery compartment provides access for
the electrical supply connections. Using flexible cable(s)
for the electrical power supply conductors requires a 2″
(51mm) strain-relief fitting (not furnished) to enable safe
access to the terminal block from which oven power is
distributed.
WARNING
Authorized supplier personnel normally accom-
plish the connections for the ventilation system,
electric supply, and gas supply, as arranged by
the customer. Following these connections, the
factory-authorizedinstallercanperformtheinitial
startup of the oven.
The supply conductors must be of the size and material
(copper) recommended to provide the current required;
(refertothedataplatefortheamperespecifications).The
electric current rating for each conductor supplying a
PS536ES-SeriesOvenmustcomplytolocalandnational
codes.
Checktheovendataplate(Figure2-11)beforemakingany
electric supply connections. Electric supply connections
must agree with data on the oven data plate.
NOTE: The electric supply installation must satisfy the
requirements of the appropriate statutory authority, such
as the National Electrical Code (NEC), ANSI/NFPA70,
(U.S.A.); the Canadian Electrical Code, CSA C22.2; the
Australian Code AG601; or other applicable regulations.

II. COMPONENT INFORMATION AND
LOCATION (Figures 3-1 and 3-2)
C. Heat Switch
A. Door Safety Switch
Turning the HEAT switch to “ON” or“I” will initially set up
the oven purge circuit. After approximately 30 seconds,
the burner lights. After the burner is lit, a flame sensor
sends a signal to the ignition module to stop the spark.
The burner will run unless the flame sensor does not
detect a flame or the heat switch is turned to the “OFF”
or “O” position.
The Door Safety Switch is located at the lower left side of
control panel opening. Opening the control panel door
permits this switch to open, disconnecting power to all
electrical controls.
CAUTION
Do NOT touch the wires going to this safety switch.
Current is always present.
TheHEATswitchisinserieswiththeburnerblowermotor

and the blower fan air pressure switch. All three safety
switches must be closed for gas to flow and the burner to

B. Blower Switch
The blower switch has two positions. The switch must be
“ON” or “I” for the burner to come on and permit the oven
towarmup.Thefancirculatestheairthroughouttheoven

The temperature controller contains a low-limit switch
whichallowstheoventocooldownto200°F(93°C)before
shutting off the blower. A high-limit indication (ALM 1) will
appear on the display if the oven reaches 650°F (343°C).
An air pressure switch monitors the air flow from the
blower, acting as a safety interlock for the burner. The

E. Conveyor
The on-off switch for the conveyor motor is on the control
panel. Also on the control panel is the digital conveyor
speed control. The digital control can be adjusted from 3
min. to 30 min. bake time (conveyor speed). Refer to
Figure3-3.
Conveyor speed is measured by the amount of time it
takes for an item to go through the bake chamber of the
oven.
