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.

Blodgett convection ovens represent the latest adĆ vancement in energy efficiency, reliability, and ease of operation. Heat normally lost, is recircuĆ lated within the cooking chamber before being vented from the oven: resulting in substantial reĆ ductions in energy consumption and enhanced oven performance.

Delivery and Location

DELIVERY AND INSPECTION

All Blodgett ovens are shipped in containers to prevent damage. Upon delivery of your new oven:

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.

D Uncrate the oven and check for internal damĆ

age. Carriers will accept claims for concealed damage if notified within fifteen days of delivery and the shipping container is retained for inĆ spection.

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 beĆ tween the oven and any combustible or nonĆcomĆ bustible construction.

D Oven body right side - 1" (2.5 cm) D Oven body left side - 1" (2.5 cm) D Oven body back - 1" (2.5 cm) D Oven body bottom - 1/2" (1.2 cm)

The following clearances must be available for serĆ vicing.

D Oven body sides - 12" (30 cm) D Oven body back - 12" (30 cm)

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

D Place the oven in an area that is free of drafts. D Keep the oven area free and clear of all combusĆ

tibles such as paper, cardboard, and flammable liquids and solvents.

D 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 moĆ tor's thermal overload device is caused by an excessive ambient temperature on the right side of the oven. This condition must be corĆ rected to prevent permanent damage to the oven.

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

1. The rating plate is located on the underside of the upper ledge above the right hand door.

NSF BOLTS

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.

D 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.

NOTE: Old style ovens refer to units with painted exĆ

posed rear angle. New style ovens refer to units with rear angle iron enclosed in steel.

The following instructions apply to stacking two new style ovens.

1. Secure the short legs to the bottom sections as described.

2. Place the upper section in position on top of the lower oven.

3. Attach the stacking brackets using the reĆ maining 5/16" bolts shipped with the ovens.

4. Attach the flue connector.

The following instructions apply to stacking a new style oven on an old style oven.

1. Secure the short legs to the bottom sections as described.

2. Place the upper section in position on top of the lower oven.

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.

WARNING!! When stacking ovens be sure to remove

the single oven flue boxes prior to attachĆ ing threeĆpiece connector.

OVEN LEVELING

After assembly, the oven should be leveled and moved to the operating location.

If the oven is moved from its regular location, the restraint must be reconnected when the oven is reĆ turned.

1. Mount the supplied bracket to the leg bolt just below the power cord.

2. Attach the clip on restraining cable to the mounting bracket.

ADJUSTMENTS ASSOCIATED WITH INITIAL INSTALLATION

Each oven, and its component parts, have been thoroughly tested and inspected prior to shipĆ ment. However, it is often necessary to further test or adjust the oven as part of a normal and proper installation. These adjustments are the responsiĆ bility of the installer, or dealer. Since these adjustĆ ments are not considered defects in material or workmanship, they are not covered by the Original Equipment Warranty. They include, but are not limited to:

D calibration of the thermostat D adjustment of the doors D leveling D tightening of fasteners.

No installation should be considered complete without proper inspection, and if necessary, adĆ justment by qualified installation or service perĆ sonnel.

OVEN OPERATION Oven Startup:

1. Toggle the POWER SWITCH (1) to ON. The

display gives the software revision level. The oven preheats to the lowest programmed first stage temperature. The LEDS (15) for all prodĆ ucts with the same first stage temperature light.

Single Product Cooking Procedure:

NOTE: If the led next to the desired product key is

lit skip step 1.

1. Press the desired PRODUCT KEY (14). The oven preheats to the first stage temperature for the selected product. When the oven reaches 10_ of the preheat temperature an alarm sounds and the DISPLAY (2) read:
