INSTALLATION INFORMATION

THE INSTALLATION INSTRUCTIONS CONTAINED HEREIN ARE FOR THE USE OF
QUALIFIED INSTALLATION AND SERVICE PERSONNEL ONLY. INSTALLATION OR
SERVICE BY OTHER THAN QUALIFIED PERSONNEL MAY RESULT IN DAMAGE TO THE
OVEN AND/OR INJURY TO THE OPERATOR.

Qualifi ed installation personnel are individuals, a fi rm, a corporation, or a company which either
in person or through a representative are engaged in and responsible for:

1. The installation or replacement of gas piping and the connection, installation, repair, or
servicing of equipment.

2. The installation of electrical wiring from the electric meter, main control box, or service outlet
to the electric appliance.

Qualifi ed installation personnel must be experienced in such work, familiar with all precautions
required, and have complied with all requirements of state or local authorities having
jurisdiction.

UTILITY INSTALLATION

LOCATION

The well-planned and proper placement of your oven will result in long-term operator convenience
and satisfactory performance.

NOTE: On gas conveyor ovens, routine servicing can usually be accomplished within the limited
movement provided by the gas hose restraint. If the oven needs to be moved further from the
wall, the gas must fi 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 suffi cient fl 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, fl ammable
liquids, and solvents. Oven should only be used on Non-Combustible Floors.

3. Do not place the oven on a curb base or seal to a wall. This will restrict the fl ow of air and
prevent proper ventilation to the blower motors. This condition must be corrected to prevent
permanent damage to the oven.

4. On all models, tripping of the blower motor's thermal overload device indicates an excessive
ambient temperature at the back of the oven. This condition must be corrected to avoid
permanent damage to the oven.

GAS SUPPLY RATING AND SIZING

Calculations for pipe sizing must take into account the maximum usage rate of all other appliances
in the kitchen or one or more of the appliances will suffer from inadequate or dangerous
performance. The 3/4" 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 gas
supply, the supply must be larger. For each oven, a 3/4" NPT fl exible quick connect hose and
full port gas shut-off valve is recommended as a MINIMUM. The main pipe supplying each oven
branch may need 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 improved access should make
any necessary service quicker resulting in less kitchen disruption. It will also allow easier
disconnection of electricity, gas, and restraints for cleaning around and behind the oven.

PRESSURE TESTING GAS SUPPLY LINE

During pressure testing note the following:

1. The oven and its individual manual shut-off valve must be disconnected from the gas supply piping
system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.45 kPa).
Turn OFF main gas shut-off valve or main gas supply line.

2. The oven must be isolated from the gas supply piping system by closing its individual manual shut­off valve during any pressure testing of the gas supply piping system at test pressures equal to or
less than 1/2 psig (3.45 kPa).

3. If incoming pressure is over 14" water column, a separate regulator for the oven must be installed
before the gas supply to the oven.

To prevent damage to the control valve regulator during the initial turn-on of
gas, it is very important to open the manual shut-off valve very slowly. After the
initial gas turn-on, the manual shut-off valve must remain open except during
pressure testing as outlined in the above steps or when necessary during service
maintenance.

NOTE: The supplied regulator is evaluated for a maximum gas supply pressure of
14" water column (34.5 mBar). The recommended maximum gas supply pressure
is 12" water column (29.9 mBar).

Installation must conform with local codes or, in the absence of local codes, with the National
Fuel Gas Code, NFPA54/ANSI Z223.1 - Latest Edition, the Natural Gas Installation Code

CAN/CGA-B149.1 or the Propane Installation Code CAN/CGA-B149.2 as applicable.

OVEN MANIFOLD PRESSURE REGULATION

Each oven has been adjusted at the factory to operate with
the gas specifi ed on the nameplate.

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 or replaced
by another model unless approved by Star Manufacturing.
A pressure reading can be taken at the test nipple provided.
You must back the set-screw one turn for this test, be certain
to re-tighten when you are done. Failure to reset the set­screw to its original position will create a gas leak once the
unit is back in operation. The reading should be taken while
the oven is heating up & at high fi re. The regulator is located
on the bottom of the gas combination valve, just inside the
control box. Adjust gas manifold regulator gas pressure by
removing the cap and adjusting the regulator adjustment
screw to match the pressure listed on the name plate (3.5"
Nat, 4.8" Propane). Clockwise to increase, counterclockwise
to decrease.

VENTILATION

INSTALLATION VENTILATION

A VENT IS REQUIRED: Local codes prevail. These are the "authority having
jurisdiction" as stated 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 depending on the location by city, 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 supplier and HVAC contractor should be contacted to provide guidance. A
properly engineered and installed ventilation hood and HVAC system will expedite approval and
reduce oven maintenance costs. Proper ventilation is the responsibility of the oven's owner.

The ventilation hood must operate in harmony with the building HVAC system. (The effi ciency
of various hood designs makes it necessary to specify such a wide range of ventilator CFM.)
Make-up air must be supplied by either a hood design or the HVAC system to avoid a negative
pressure condition. This will vary with hoods from various manufacturers. Air supplied directly
from outside the building to the kitchen or oven area, non-tempered, could be used as supply
air but the design would have to accommodate potential operational changes.

of the cooking area.

The following drawing shows a typical
installation and is intended to be a guideline.
This is not a rigid specification. Hood
dimensions and positioning over the oven
will vary with hood manufacturer & local
guidelines.

CAUTION

Damage sustained as a direct result of
improper ventilation will not be covered by

IL1177

the warranty.

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.

SMOKE CANDLE TEST

In order to verify the proper function of your ventilation system, a smoke candle test should
be done. If testing a multiple oven system, this test should be done on the bottom oven. The
conveyor coupling should be disconnected so conveyor does not move 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 cake pan.

3. Insert candle through conveyor tunnel or oven

door. (Use Star Smoke Candle 2W-Z5668.)

4. Light the fuse of the smoke candle and
immediately center the pan in the oven cavity on
the conveyor belt (keeping the oven door and
window closed).

5. Observe the smoke pattern coming out of
all oven openings and the collection of this
smoke by the ventilation system.

6. All smoke from the oven must be captured
by the ventilation system.

DISPLAY INFORMATION

OPERATION

When operating the oven, there are different levels of access:

1. Store Level - General employees would know these functions and how to change them. While the

oven is running, enter this mode by holding the DOWN and UP arrows (

) simultaneously for four

seconds. The TIME display goes blank and the TEMP setpoint is displayed. Adjust with the DOWN
or UP arrows. The ENTER button (

) toggles between TIME and TEMP. The parameter that can
be adjusted is displayed, the other is blank. When TIME and TEMP are adjusted as needed, wait fi ve
seconds and SAVE is displayed. The values are accepted and the controller begins controlling to these
new values. The conveyor continues to operate at the same speed until a new value is accepted. The
temperature control output should be OFF during changes.

2. Manager Level - This is a lock so that TIME and TEMP cannot be changed even at the Store Level.

While the oven is running, enter this mode by holding the DOWN and UP arrows simultaneously for 4
seconds. The TIME display goes blank and the TEMP setpoint is displayed. Release the UP arrow
and continue to hold the DOWN arrow for an additional 4 seconds. The TEMP display shows LOC
as the TIME display shows nO, which indicates that the TIME/TEMP parameters can be changed.
after reaching the STORE level. yES indicates that the parameters cannot be changed even after

entering the STORE level. The LOC setting can be toggled using the ENTER button (

).

ADDITIONAL FUNCTIONS

The conveyor belt direction and the temperature display can be changed on the conveyor oven by a qualifi ed
technician. To change the belt direction, the technician needs to see the section on "CONVEYOR BELT
DIRECTION". A technician can also change the temperature display from Fahrenheit to Celsius. These
changes can be made by the technician during the start-up/check-out or at a later date.

ERROR CODES

Error codes will display as fl ashing text messages for diagnostic purposes. Any temperature or thermocouple
error should turn the temperature output OFF and leave the conveyor running at the same speed. The
belt error should turn the temperature output OFF. The speed error should display when the motor is
unable to settle at the chosen speed. This might occur if a fast speed is chosen that the motor is unable
to spin fast enough to achieve. The speed signal output will remain the same but the display will fl ash
the error message.

IL1188

BAKE TIME VERSUS TEMPERATURE

1. Bake time is actually conveyor speed and is
defi ned as the time the product is actually in the
oven. This is measured by noting the time when
the leading edge of the product enters the oven
and the time the leading edge of the product
leaves the oven. This is adjusted by using the
conveyor speed controller.

2. Bake temperature is adjusted by changing the
setpoint of the temperature controller to the
desired bake temperature. When the oven
reaches the desired temperature, the red dot in
the lower right corner of the temperature display
will turn off and on as the controller maintains
the temperature.

3. When establishing a bake time and temperature
for a given product, the general rule shall be as
the bake time increases the bake temperature
decreases and the reverse is also true; increase
temperature, decrease time. However, there
are limits to the above rule. Going to extremes
will result in a burnt exterior and raw interior or
it will result in a very light color but over-baked
product.

4. Once a good bake has been established, the fi ne
adjustments should be made by holding either
the bake time or bake temperature constant,
then varying the other.

CONVEYOR SPEED

Bake Time (Conveyor Speed) - As stated previously,
bake time (conveyor speed) is defi ned as the amount
of time elapsed between the time the leading edge of
the product enters the oven and the leading edge of
the product exits the oven. Bake time is controlled by
adjusting the digital speed controller. The setting on
the control panel indicates the actual bake time.

Bake time will be the same for any size
product.

TIME OF DELIVERY

The time of delivery is the amount of elapsed time
between the period when the leading edge of the
product enters the oven and the trailing edge of
the product is fully discharged and is ready to be

delivered to the customer.

Time of delivery changes if the product size
changes.

Tip: Train yourself not to pull the product out of the

oven when the leading edge comes out. Always wait
until the entire product is out - the product needs this
time to fully bake.

MAINTENANCE INSTRUCTIONS

DISCONNECT THE POWER SUPPLY BEFORE SERVICING OR CLEANING THIS
OVEN. SAFEGUARD THE POWER SO IT CANNOT BE ACCIDENTALLY RESTORED.
FAILURE TO DO SO COULD RESULT IN DISMEMBERMENT, ELECTROCUTION,
OR FATAL INJURY. THERE IS MORE THAN ONE POWER SUPPLY CONNECTION
POINT WHEN OVENS ARE STACKED, SO MAKE SURE THAT ALL SWITCHES ARE
IN THE OFF POSITION BEFORE CLEANING OR MAINTENANCE.

No electrical components should be subjected to moisture. It is therefore important that the oven
is wiped down carefully. NEVER throw buckets of water over the oven or subject it to pressure
washing from a hose or a pressure spray. If water or other liquid is spilled on the oven, make
sure that none of it has entered the control box area before switching the oven ON. If in doubt,
call your service company.

Adhere to the following warnings when cleaning or maintaining your gas conveyor oven:

1. The oven must be cool. Do not use power cleaning equipment, steel wool, or wire brushes
on stainless steel surfaces.

2. Do not use a caustic or an alkaline base cleaner on the interior of the oven. This will ruin
the aluminized fi nish of the oven interior.

3. When using cleaning solutions, be sure they meet local and national health standards.

If the gas oven needs to be moved, the gas must be turned off and disconnected
from the unit before removing the restraint. Reconnect the restraint after the oven
has been returned to its original location.

Follow this recommended cleaning schedule for proper oven performance:

CAUTION

CONVEYOR BELT TENSION

The conveyor belt of the Ultra-Max Gas Conveyor
Oven does not have a tension adjustment. If the
belt becomes too loose, a link will have to be
removed to tighten. A belt that is too tight will
also cause operational problems due to excessive
drag. We suggest that you have a qualifi ed service

technician perform this adjustment.

CAUTION
Careful consideration should be exercised
prior to removing a belt link because a belt
that is too tight will impede the smooth
operation of the conveyor.

CONVEYOR BELT LINK REMOVAL

An entire link can be removed with the conveyor
assembly either in or out of the oven. This
may be necessary as the belt stretches after
continuous use. Following are the necessary
steps for removing links:

1. Move the splice clips to either end of the
oven for easy access.

2. Unhook the splice clips using long nose
pliers.

3. Unhook the full link to be removed and
slide it out. Do not discard the link removed
as it may be used for making spare splice
clips.

4. Reconnect the inside splice clips.

5. Reconnect the outside splice clips.

6. Replace all parts removed from the
oven.

7. Straighten any bent wires to ensure smooth
sprocket engagement.

Remove the outside master links on the right and left
sides of the conveyor belt. Remove the center splice
clips next.

Unhook the end loop and pull up on the link section.
Save this link as it may be used for making splice clips.
