Installation

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 continually strips away the layer of cool air surrounding the product, quickly allowing the heat to penetrate. The result is a high quality product, cooked at a lower temperature in a shorter amount of time.
Blodgett convection ovens represent the latest advancement in energy efficiency, reliability, and ease of operation. Heat normally lost, is recirculated within the cooking chamber before being vented from the oven: resulting in substantial reductions in energy consumption and enhanced oven performance. ELECTRICAL RATINGS

• Electric connection wiring is sized for 90ºC copper wire at 125% of rated input.
  DELIVERY AND INSPECTION
  All Blodgett ovens are shipped in containers to prevent damage. Upon delivery of your new oven:

  • Inspect the shipping container for external damage. 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 damage. Carriers will accept claims for concealed damage if notified within fifteen days of delivery and the shipping container is retained for inspection.

The Blodgett Oven Company cannot assume responsibility for loss or damage suffered in transit.
The carrier assumed full responsibility for delivery in good order when the shipment was accepted. We are, however, prepared to assist you if filing a claim is necessary.
OVEN LOCATION
The well planned and proper placement of your oven will result in long term operator convenience and satisfactory performance.
The following clearances must be maintained between the oven and any combustible or non-combustible construction.
Zephaire-100-E

• Oven body right side – 0” (0 cm)
• Oven body left side – 0” (0 cm)
• Oven body back – 0” (0 cm)
• Single and stacked oven bottom – 4-1/2” (11.4 cm)

Zephaire-200-E

• Oven body right side – 1/2” (1.3 cm)
• Oven body left side – 1/2” (1.3 cm)
• Oven body back – 1/2” (1.3 cm)
• Single and stacked oven bottom – 1/2” (1.3 cm)

Adequate clearances must be available for servicing.

• Keep the oven area free and clear of all combustibles such as paper, cardboard, and flammable liquids and solvents.
• Do not place the oven on a curb base or seal to a wall. This will restrict the flow of air and prevent proper ventilation resulting in damage to the oven.

Before making any utility connections to this oven, check the rating plate to be sure the oven specifications are compatible with the electrical services supplied for the oven.
1. Pull out control panel. The rating plate attached to the inside of the control compartment.

• Do not place strong sources of heat such as open flame ranges, griddles, or charbroilers near the oven. If such an instance exists, it is highly recommended to purchase a heat shield, available from Blodgett.
• Note that if temperatures are too high, a safety shutdown may occur.
• Failure to comply may invalidate the oven warranty.

NSF BOLTS
These bolts are required by NSF to block any exposed hole on the back of an oven. This includes:

• any unit, single or stacked, without a back panel.
• any holes in stacked units not used for mounting stacking brackets.

1. Locate the 5/16” bolts that were shipped with the oven.
2. Install the bolts as shown

LEG ATTACHMENT

1. Push the oven onto a lift with the bottom of the oven down.

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 tighten to the nearest full turn.

3. Align the two leg plate holes in each leg with those in the oven bottom. Secure each leg using two 1/2” bolts.
   NOTE: If using casters see CASTER ASSEMBLY before proceeding.

4. Level the oven by screwing the adjustable leg feet in or out as necessary.

CASTER ASSEMBLY
NOTE: Install the locking casters on the front of the oven. Install the non- locking casters on the back of the oven.
Casters for Single and Double Stacked Ovens:

General Guidelines for Operating Personne l
COOK TIMES AND TEMPERATURES
Preheating the oven
Always preheat the oven before baking or roasting. We recommend preheating 50°F (28°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  emperature after the product is loaded.
NOTE: For frozen product, preheat the oven 100°F (56°C) above the cook temperature.
Cook Temperatures
Generally, cook temperatures should be 50°F (28°C) lower than deck or range oven recipes. If the edges of the product are done but the center is raw, or if there is color variation, reduce the thermostat setting another 15-25°F (10-15°C). Continue to reduce the cook temperature on successive loads until the desired results are achieved.
NOTE: Cooking at excessive temperatures will not reduce cook time, it will produce unsatisfactory baking and roasting results.
Cook Time
Check the product in about half the time recommended for deck or range oven recipes. Record times and temperatures which provide best results for future reference.
NOTE: Cook time will vary with the amount of product loaded, the type of pan and the temperature.
OPERATING TIPS
Pans and Racks
Product or pan height determines how many racks are used. The oven holds up to ten 18” x 26” (45.7 x 66.0 cm) bun pans.
Load the oven from the bottom, centering the pans on the rack. Never place a pan or aluminum foil on the bottom of the oven. This obstructs the flow of air and results in uneven baking and roasting.
Roasting
To reduce shrinkage when roasting, place meat directly on the racks. Place a sheet pan one-half full of water in the bottom rack position. The water evaporates, increasing humidity in the oven chamber. The pan catches grease from the meat, making oven cleaning easier.
Baking
Weigh the product to ensure equal distribution in each pan. Varying amounts of product will cause uneven baking results.
Fans
The fan must be operating for the oven to heat. Use the Pulse Plus feature to allow light or liquid product to set in the pan and to avoid rippling towards the fan. If your oven is not equipped with this feature use the following procedure.

1. Preheat the oven 25°F (15°C) above the baking temperature.
2. Load the oven with product. Close the doors.
3. Set the thermostat to the baking temperature.
4. Turn the oven off.
5. Allow the product to set for 5-7 minutes with the fan off. The residual heat in the oven sets the product.
6. Turn the oven on for the remainder of the bake.

Lights
Turn the oven lights off when not viewing the product.
Leaving the lights on for extended periods of time shortens the bulb life considerably.

Maintenance

Cleaning and Preventative Maintenance
CLEANING THE OVEN
WARNING!!
Always clean the unit when it is cold.
WARNING!!
Be sure to read and follow the MSDS or safety instructions on the bottle for your oven cleaner.
Cleaning the Exterior

1. Saturate a cloth with stainless steel cleaner and wipe down the exterior.
   NOTE: Heat tint and heavy discoloration may be removed with any non- caustic commercial oven cleaner.

2. Dry the oven with a clean cloth.

Cleaning the Oven Interior

1. Remove the racks, rack supports and blower wheel cover (back panel) from the oven. Soak the parts in a solution of ammonia and water.
   NOTE: To remove the blower wheel cover loosen the screws in each corner. Then lift up and out.

2. The porcelain interior can be cleaned with any commercial oven cleaner.
   Be sure caustic cleaning compounds DO NOT come in contact with the temperature probe, heating element, and blower wheel. Let the cleaner sit for 10-20 minutes or the length of time recommended on your cleaner.

3. Wipe out the cleaner with a wet cloth.

4. Reinstall the racks, rack supports and blower wheel cover.

Weekly Cleaning
Be sure the air intake (cooling fan) behind the oven is free of all lint, grease or other air flow inhibitors. Keeping the air intake free of obstructions will extend the life of the oven components.          

PREVENTATIVE MAINTENANCE
The best preventative maintenance measures are, the proper installation of the equipment and a program for routinely cleaning the ovens.
Annual Maintenance
This oven requires no lubrication, however, the venting system should be checked annually for possible deterioration resulting from moisture and corrosive flue products. If maintenance or repairs are required, contact your local Blodgett service company, a factory representative or the Blodgett Oven company.
WARNING!!
Always disconnect the appliance from the power supply before servicing or cleaning.
