Introduction Oven Description and Specifications Cooking in a convection oven differs from cooking in a conventional deck or range oven since heated air is constantly recirculated over the product by a fan in an enclosed chamber. The moving air conĆ tinually strips away the layer of cool air surroundĆ ing the product, quickly allowing the heat to peneĆ trate. The result is a high quality product, cooked at a lower temperature in a shorter amount of time.
Introduction Oven Components Combustion Cover - provides access to the combustion compartment on gas ovens. Rack Supports - hold oven racks. Blower Wheel Cover - located on the back interiĆ or wall of the oven. Protects the blower wheel. Combustion Compartment - contains combusĆ tion burners on gas ovens. Blower Wheel - spins to circulate hot air in the baking chamber. Combustion Burners - provide heat to the bakĆ ing chamber on gas ovens. Convection Motor - provides power to turn the blower wheel.
Installation Delivery and Location DELIVERY AND INSPECTION It is essential that an adequate air supply to the oven be maintained to provide a sufficient flow of combustion and ventilation air. All Blodgett ovens are shipped in containers to prevent damage. Upon delivery of your new oven: D D D Inspect the shipping container for external damĆ age. Any evidence of damage should be noted on the delivery receipt which must be signed by the driver. Uncrate the oven and check for internal damĆ age.
Installation Oven Assembly NSF BOLTS any holes in stacked units not used for mountĆ ing stacking brackets. 1. Locate the 5/16" bolts that were shipped with the oven. 2. Install the bolts as shown in Figure 3. D These bolts are required by NSF to block any exĆ posed hole on the back of an oven. This includes: D any unit, single or stacked, without a back panel.
Installation Oven Assembly LEG ATTACHMENT 1. Lay the oven on its back. 2. Align the threaded stud in each leg with the nut located inside each bottom corner of the oven frame. Turn the legs clockwise and tightĆ en to the nearest full turn. 3. Align the two leg plate holes in each leg with those in the oven bottom. Secure each leg usĆ ing two 1/2" bolts. NOTE: If using casters see CASTER ASĆ SEMBLY before proceeding. 4. Tip the oven up on the legs. 5.
Installation Oven Assembly DOUBLE SECTION ASSEMBLY 3. Attach the stacking brackets using the reĆ maining 5/16" bolts shipped with the ovens. 4. Drill a clearance hole for a 5/16" bolt in the angle iron of the old style oven. Use the holes in the stacking brackets as a pilot. 5. Attach the stacking brackets to the old style oven with the 5/16" bolts and nuts provided in the kit. 6. Attach the flue connector. NOTE: Old style ovens refer to units with painted exĆ posed rear angle.
Installation Ventilation CANOPY TYPE EXHAUST HOOD On gas models the installation of a proper ventilaĆ tion system cannot be over emphasized. This sysĆ tem removes unwanted vapors and products of combustion from the operating area. A mechanically driven, canopy type exhaust hood is the preferred method of ventilation. The hood should be sized to completely cover the equipment plus an overhang of at least 6" (15 cm) on all sides not adjacent to a wall.
Installation Ventilation DIRECT FLUE ARRANGEMENT Installing the draft hood When the installation of a mechanically driven exĆ haust hood is impractical the oven may be vented by a direct flue arrangement. Ovens ordered for direct venting are supplied with a draft hood. Install the draft hood as follows: 1. Place the draft hood over the flue connector. See Figure 9. 2. Secure both ends with the sheet metal screws provided. WARNING!! It is essential that the direct flue be installed as follows.
Installation Utility Connections - Standards and Codes THE INSTALLATION INSTRUCTIONS CONĆ TAINED HEREIN ARE FOR THE USE OF QUALIĆ FIED 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.
Installation Gas Connection GAS PIPING A properly sized gas supply system is essential for maximum oven performance. Piping should be sized to provide a supply of gas sufficient to meet the maximum demand of all appliances on the line without loss of pressure at the equipment. Example: NOTE: BTU values in the following example are for natural gas. You purchase a ZephaireĆG convection oven to add to your existing cook line. 1. Add the BTU rating of your current appliances.
Installation Gas Connection PRESSURE REGULATION AND TESTING ZephaireĆG ovens are rated at 60,000 BTU/Hr. (17.6 kW) (63 MJ) per section. Each oven has been adjusted at the factory to operate with the type of gas specified on the rating plate. DO NOT INSTALL AN ADDITIONAL REGULATOR WHERE THE OVEN CONNECTS TO THE GAS SUPPLY UNLESS THE INLET PRESSURE IS ABOVE MAXIMUM. Inlet Pressure Natural Propane Min Max Min Max W.C. 7.0 10.5 11.0 13.0 kPa 1.43 2.61 2.74 3.
Installation Gas Connection GAS HOSE RESTRAINT If the oven is mounted on casters, a commercial flexible connector with a minimum of 3/4" (1.9 cm) inside diameter must be used along with a quick connect device. The restraint, supplied with the oven, must be used to limit the movement of the unit so that no strain is placed upon the flexible connector. With the restraint fully stretched the connector should be easy to install and quick connect. The restraint (ie: heavy gauge cable) should be 1,000 lb.
Installation Electrical Connection Wiring diagrams are located in the control compartment and on the back of the oven. WARNING!! This appliance is equipped with three prong grounding type plug for your protection against shock hazard and should be plugged directly into a properly grounded three prong receptacle. DO NOT cut or remove the grounding prong from this plug. This oven is supplied for connection to 115 volt grounded circuits.
Installation Initial Startup The following is a checkĆlist to be completed by qualified personnel prior to turning on the appliance for the first time. j Open the manual shutĆoff valve at the rear of the oven. j Remove the control panel and combustion covers. j Turn the combination valve's manual shutĆoff to the on position. j Turn the selector switch to Cook, and the therĆ mostat to 500_F (260_C).

Operation General Guidelines for Operating Personnel COOK TIMES AND TEMPERATURES OPERATING TIPS Preheating the oven Pans and Racks Always preheat the oven before baking or roastĆ ing. We recommend preheating 50_F (10_C) above the cook temperature to offset the drop in temperature when the doors are opened and cold product is loaded into the oven. Set the thermostat to the cook temperature after the product is loaded. Product or pan height determines how many racks are used.
