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.

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.

• Oven body right side - 6” (15 cm)

• Oven body left side - 6” (15 cm)

• Oven body back - 6” (15 cm)

• Oven body bottom - 4.5” (11.4 cm)

The following clearances must be available for servicing.

• Oven body sides - 12” (30 cm)

• Oven body back - 12” (30 cm)

NOTE: On gas models, 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 first be turned off and disconnected from the oven before removing the restraint.

Reconnect the restraint after the oven has been returned to its normal position.

Installation

Delivery and Location

It is essential that an adequate air supply to the oven be maintained to provide a sufficient flow of combustion and ventilation air.

• Place the oven in an area that is free of drafts.

• 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. Tripping of the blower motor’s thermal overload device is caused by an excessive ambient temperature on the right side of the oven.

This condition must be corrected to prevent permanent damage to the oven.

• The location must provide adequate clearance for the air opening into the combustion chamber.

Before making any utility connections to this oven, check the rating plate to be sure the oven specifications are compatible with the gas and electrical services supplied for the oven.

1. Pull out control panel. The rating plate attached to the inside of the control compartment.

DIREct FLUE ARRAnGEMEnt

When the installation of a mechanically driven exhaust hood is impractical the oven may be vented by a direct flue arrangement.

WARnInG!!

It is essential that the direct flue be installed as follows. Incorrect installation will result in unsatisfactory baking and oven damage.

The flue must be class B or better with a diameter of 6”

(15 cm). The height of the flue should rise 6-8 ft (2-2.5 m) above the roof of the building or any proximate structure.

Never direct vent the oven into a hood. The flue should be capped with a UL Listed type vent cap to isolate the unit from external environmental conditions.

The direct vent cannot replace air consumed and vented by the oven. Provisions must be made to supply the room with sufficient make-up air. Total make-up air requirements for each oven section should be approximately 30

CFM (.85m3) per section. To increase the supply air entering the room, a ventilation expert should be consulted.

Installing the draft hood

Ovens ordered for direct venting are supplied with a draft hood. Install the draft hood as follows:

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 Zephaire-200-G to add to your existing cook line.

1. Add the BTU rating of your current appliances.

Pitco Fryer

6 Burner Range

Deck Oven

120,000 BTU

60,000 BTU

50,000 BTU

Total 230,000 BTU

2. Add the BTU rating of the new oven to the total.

Previous Total

Zephaire-200-G

230,000 BTU

60,000 BTU

New Total 290,000 BTU

3. Measure the distance from the gas meter to the cook line. This is the pipe length. Let’s say the pipe length is 40’ (12.2 m) and the pipe size is 1” (2.54 cm).

4. Use the appropriate table to determine the total capacity of your current gas piping.

The total capacity for this example is 320,000 BTU. Since the total required gas pressure, 290,000 BTU is less than

320,000 BTU, the current gas piping will not have to be increased.

NOTE: The BTU capacities given in the tables are for straight pipe lengths only. Any elbows or other fittings will decrease pipe capacities. Contact your local gas supplier if you have any questions.

Operation

General Guidelines for operating Personnel

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 temperature 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.
