Page 4: General Information
GENERAL INFORMATION This equipment is designed and sold for commercial use only by personnel trained and experienced in its operation and is not sold for consumer use in and around the home nor for use directly by the general public in food service locations. First and foremost, each crate should be examined before signing the Bill of Lading to report any visible damage by the trucker in transit and to account for the proper number of crates. If there is apparent damage, arrangements should be made to file a claim against the carrier. Interstate Commerce Regulations require that the claim must be initiated by the consignee. Proper and secure storage facilities should be arranged for the oven(s) if necessary to protect it from outdoor or damp conditions at all times before installation. -IMPORTANT- When you have all the crates unloaded, open the crates and remove all plastic covers. Inspect at once for concealed damage. If anything appears to be damaged, contact the appropriate persons immediately to file a damage claim. -

Page 6: Installation Information
INSTALLATION INFORMATION THE INSTALLATION INSTRUCTIONS CONTAINED HEREIN ARE FOR THE USE OF QUALIFIED INSTALLATION A ND SERVICE PERSONNEL ONLY. INSTALLATION OR SERVICE BY OTHER THAN QUALIFIED PERSONNEL MAY RESULT IN DAMAGE TO THE OVEN AND/OR INJURY TO THE OPERATOR. Qualified installation personnel are individuals, a firm, 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. Qualified 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. -
Page 7: Smoke Candle Test
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 throughout the country 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. -
Page 8: Access Considerations
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 1/2" 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 gas supply, the supply must be larger. For each oven, a 3/4" NPT flexible 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. ELECTRICAL CONNECTION Before making any electrical connections to this unit, check that the power supply is adequate for the voltage, 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 with the National Electric Code, ANSI-NFPA 70, latest version, manufacturer's installation instructions, and applicable local municipal building codes. In Canada, all electrical connections are to be in accordance with CSA C22.1 - Canadian Electrical Code Part 1 and/or local codes. -
Page 9: Stacking Instructions
WARNING: 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. STACKING INSTRUCTIONS The following instructions should be followed when stacking more than one unit. Single Oven (or Bottom) Cart Install: 1. Remove door, conveyor, and finger assemblies. 2. Unbolt unit from shipping crate (2 bolts). 3. Turn unit on front as shown. 4. Slide legs into stand shelf and thread legs into bottom of oven. 5. Install casters into bottom of legs.

Page 14: Maintenance Instructions
MAINTENANCE INSTRUCTIONS DISCONNECT THE POWER SUPPLY BEFORE SERVICING OR CLEANING THIS OVEN. SAFEGUARD THE POWER SO IT CANNOT BE A CCIDENTALLY RESTORED. FAILURE TO DO SO COULD RESULT IN DISMEMBERMENT, ELECTROCUTION, WARNING 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. CAUTION 2. Do not use a caustic or an alkaline base cleaner on the interior of the oven. This will ruin the aluminized finish of the oven interior. - Page 15 DIRECTIONS FOR DISASSEMBLY 1. Remove crumb trays and 2. Push the spring-loaded coupling 3.

Page 16: Conveyor Belt Tension
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 qualified 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. Remove the outside master links on the right and left sides of the conveyor belt. Remove the center splice clips next. 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. - Page 17 Visit our Website at: www.star-mfg.com Email: service@star-mfg.com THOROUGHLY INSPECT YOUR UNIT ON ARRIVAL This unit has been tested for proper operation before leaving our plant to insure delivery of your unit in perfect condition.
