LOCATION
Thewell-plannedand proper placement of your oven
will result in long-term operator convenience and
satisfactory performance.
NOTE: Ongasconveyorovens,routineservicingcan
usuallybeaccomplishedwithinthelimitedmovement
provided by the gas hose restraint. If the oven needs
to be moved further from the wall, the gas must rst
be turned off and disconnected from the oven before
removing the restraint. Reconnect the restraint after
the oven has been returned to its regular position.
It is essential that an adequate air supply to the oven
be maintained to provide a sufcient ow of combustion
and ventilation air. Follow these guidelines:
1. Place the oven in an area that is free of drafts.
2. Keep the oven area free and clear of all
combustibles such as paper, cardboard, ammable
liquids, and solvents.
3. Do not place the oven on a curb base or seal to a
wall. This will restrict the ow of air and prevent
proper ventilation to the blower motors. This
conditionmustbecorrectedtopreventpermanent
damage to the oven.
4. On all models, tripping of the blower motor's
thermal overload device indicates an excessive
ambienttemperatureatthebackoftheoven. This
condition must be corrected to avoid permanent
damage to the oven.
CAUTION
Failure to properly vent the oven can be
hazardous to the health of the operator
and may result in operational problems,
unsatisfactory baking, and possible damage
to the equipment.
Damage sustained as a direct result of improper
ventilation will not be covered by the warranty.
VENTILATION
AVENTISREQUIRED: Localcodesprevail. These
arethe "authority having jurisdiction"asstated by the
National Fire Protection Association, Inc. in NFPA
96-Latest Edition. For further ventilation information
see below.
A ventilation hood is required to remove heat and
cooking odors. For gas ovens, a ventilation hood is
also required to remove the products of combustion.
The hood and HVAC installation must meet local
codes to gain approval by the authority having
jurisdiction. Requirements may vary throughout the
countrydependingonthelocationbycity,county,and
state. Obtain information from the authority having
jurisdiction to determine the requirements for your
installation. Obtain information and review copies
of codes or documents that will be used to inspect
and approve your installation. Your ventilation hood
supplierandHVACcontractorshould becontactedto
provideguidance. Aproperlyengineeredandinstalled
ventilation hood and HVAC system will expedite
approvalandreduceovenmaintenancecosts. Proper
ventilation is the responsibility of the oven's owner.
Theventilationhoodmustoperateinharmonywiththe
building HVAC system. It typically requires between
750 and 2500 CFM exhaust. (The efciency of various
hood designs makes it necessary to specify such a
wide range of ventilator CFM.) Make-up air must be
suppliedbyeither ahooddesignorthe HVACsystem
to avoid a negative pressure condition. This will vary
with hoods from various manufacturers.
CAUTION
Prevent airow through the cooking tunnel.

or rear or to the sides of the cooking area.

The following drawing shows a typical installation
and is intended to be a guideline. This is not a rigid
specication. Hood dimensions and positioning over
the oven will vary with hood manufacturer.
SMOKE CANDLE TEST
Inordertoverifytheproperfunctionofyourventilation
system,asmokecandletestshouldbedone. Iftesting
a multiple oven system, this test should be done on
the bottom oven. The conveyor coupling should be
disconnected and the oven temperature must be set
and operating at a minimum of 480°F (249°C).
Test Procedure:
1. Wear heat-resistant gloves to prevent burns.
2. Put the smoke candle in an 8"x8"x2" cake pan.
3. Insert candle through conveyor tunnel or oven
door. (Use Star Smoke Candle 2W-Z5668.)
4. Lightthefuseofthesmokecandleandimmediately

6. All smoke from the oven must be captured by the
ventilation system.
GAS SUPPLY RATING AND SIZING
Calculations for pipe sizing must take into account
themaximumusagerateofallotherappliancesinthe
kitchenoroneormoreoftheapplianceswillsufferfrom
inadequateordangerousperformance. The1/2"NPT
connection for the oven is generously sized for use
in the control box of the oven. However, unless the
oven installation is within 10 feet of the main building
gassupply,thesupplymustbelarger. Foreachoven,
a 3/4" NPT exible quick connect hose and full port
gas shut-off valve is recommended as a MINIMUM.
Themainpipesupplyingeachovenbranchmayneed
to be larger depending on the number of appliances
serviced, the number of elbows in the piping, and
the pressure. This should be sized and installed by
a professional familiar with any local codes that may
also affect the installation.
ACCESS CONSIDERATIONS
Locating the gas valve(s), quick connect hose(s) and
electrical outlet(s) at the control box end of the oven
will allow easier access for any service visits. This
improvedaccessshouldmakeanynecessaryservice
quickerresulting inless kitchendisruption. Itwillalso
allow easier disconnection of electricity, gas, and
restraints for cleaning around and behind the oven.
ELECTRICAL CONNECTION
Before making any electrical connections to this unit,
checkthatthepowersupplyisadequateforthevoltage,
amperage, and phase requirements stated on the
rating plate. A wiring diagram is included herewith.
When installed, this appliance must be electrically
grounded and its installation must comply withANSI-
NFPA 70, latest version, manufacturer's installation
instructions, and applicable local municipal building
codes. InCanada,allelectricalconnectionsaretobe

PRESSURE REGULATION AND TESTING
Eachovenhasbeenadjustedatthefactorytooperate
withnaturalgas. Partscanbeorderedforconversion
for use with propane.
Each oven is supplied with a regulator to maintain
the proper gas pressure. The regulator is essential
to the proper operation of the oven and should not be
removed. Apressure reading can be taken at one of
the 1/8" NPT test ports on the bottom or side of the
combinationvalve. Thereadingshouldbetakenwhile
theovenisheatingup. Theregulatorislocatedonthe
bottom of the gas combination valve, just inside the
control box. There is no need to install an additional
regulator where the oven connects to the gas supply
unless the supply exceeds the maximum.
NOTE: The supplied regulator is evaluated for a
maximum gas supply pressure of 14" water column
(34.5mBar).Therecommendedmaximumgassupply
pressure is 12" water column (29.9 mBar).
