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 opera-tion. 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.

BDO-100-G-ES

• Oven body right side – 0” (0cm)

• Oven body left side – 0” (0cm)

• Oven body back – 0” (0cm)

• Single and stacked oven bottom – 0” (0cm)
  The following clearances must be available for servicing.

• Oven body sides – 12” (30cm)

• Oven body back – 12” (30cm)

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.

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.
• NSF requires 6” of clearance on the bottom and sides of the unit for cleaning. Do not place the oven on a curb base or seal to a wall.
• 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 the control panel. The rating plate is 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.

Oven Assembly

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.

NOTE : Use a gas hose restraint on all units with casters. Casters for Single and Double Stacked Ovens:

1. Attach the legs as described.
2. Pry the adjustable feet out of the legs.
3. Insert one caster into each leg as shown. Tighten the lock nuts to secure the casters.

Low Profile Casters for Double Stacked Ovens:

1. Align the three holes in each caster assembly plate with those in the oven bottom. Secure each caster using three 1/2” bolts.

2. Place the upper section in position on top of the lower oven.
3. Attach the stacking brackets using the remaining 5/16” bolts shipped with the ovens.
4. Attach the draft diverter to the bottom oven. DO NOT install the draft diverter guard on the bottom oven.
5. Install the flue riser on the top oven. The bottom of the flue riser slides down over the draft diverter on the bottom oven. Secure with 12 screws.
6. Install the flue riser guard as shown below.

OVEN LEVELING
After assembly, the oven should be levelled and moved to the operating location.

1. The oven can be levelled by adjusting the feet or casters located on the bottom of each leg.

On gas models, the installation of a proper ventilation system cannot be over- emphasized. This system removes unwanted vapours and products of combustion from the operating area. This oven may be vented using either:

• A mechanically driven, canopy type, exhaust hood, or
• A direct flue arrangement.

U.S. and Canadian installations
Refer to your local ventilation codes. In the absence of local codes, refer to the National ventilation code titled, “Standard for the Installation of Equipment for the Removal of Smoke and Grease Laden Vapors from Commercial Cooking Equipment”, NFPA-96-Latest Edition.

General export installations
Installation must conform with Local and National installation standards. Local installation codes and/or require-ments may vary. If you have any questions regarding the proper installation and/or operation of your Blodgett oven, please contact your local distributor. If you do not have a local distributor, please call the Blodgett Oven Company at 0011-802-658-6600.

WARNING : Failure to properly vent the oven can be hazardous to the health of the operator and may result in operational problems, unsatisfactory baking and possible damage to the equip-ment. Damage sustained as a direct result of improper ventilation will not be covered by the manufacturer’s warranty.

Ventilation

CANOPY TYPE EXHAUST HOOD
A mechanically driven, canopy-type exhaust hood is the preferred method of ventilation. The hood should be sized to completely cover the equip-ment plus an overhang of at least 6” (15 cm) on all sides not adjacent to a wall. The distance from the floor to the lower edge of the hood should not exceed 7’ (2.1m). The total makeup and exhaust air requirements for hood capacity should be approximately 30 CFM (.85 m3) for each oven section.

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

1. Place the draft diverter on the oven back and slide it up through the rectangular hole in the oven body top. Secure the oven body back with four screws.
2. Secure the draft diverter guard to the draft diverter with four screws.

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: The direct flue must be  installed as follows. Incorrect installation will result in unsatisfactory baking and oven damage.

The flue must be class B or better. 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 of 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 require-ments for each oven section should be approximately 30 CFM (.85 m3) per section. To increase the supply of air entering the room, a ventilation expert should be consulted.

Gas Connection

GAS PIPING
A properly sized gas supply system is essential for maximum oven performance. Piping should be sized to supply gas sufficient to meet the maximum demand of all appliances on the line without loss of pressure on the equipment.

Example:

NOTE : BTU values in the following example are for natural gas. You purchase a BDO-100-G-ES to add to your existing cook line.

1. Add the BTU rating of your current appliances.

   • Pitco Fryer : 120,000 BTU
   • 6 Burner Range: 60,000 BTU
   • Deck Oven: 50,000 BTU
   • Total: 230,000 BTU

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

   • Previous Total: 230,000 BTU
   • BDO-100-G-ES: 45,000 BTU
   • New Total: 275,000 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 capacity, 275,000 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.

PRESSURE REGULATION AND TESTING
BDO-100-G-ES ovens are rated at 45,000 BTU/Hr. (13.2 kW) (48 MJ) per section. Each oven has been adjusted at the factory to operate with the type of gas specified on the rating plate.

INLET PRESSURE

 | Natural| Propane
Min| Max| Min| Max
W.C.| 7.0| 10.5| 11.0| 13.0
kPa| 1.742| 2.61| 2.74| 3.23
MANIFOLD PRESSURE
 | Natural| Propane
W.C.| 3.5| 10.0
kPa| .87| 2.49

• Inlet Pressure: the pressure of the gas before it reaches the oven.
• Manifold Pressure:  the pressure of the gas as it enters the main burner(s).
• Min: the minimum pressure recommended to operate the oven.
• Max:  the maximum pressure at which the manufac-turer warrants the oven’s operation.

Gas Connection

• Each oven is supplied with a regulator to maintain the proper gas pressure. The regulator is essential to the proper operation of the oven and should not be removed. It is preset to provide the oven with 3.5” W.C. (0.87 kPa) for natural gas and 10.0” W.C. (2.50 kPa) for Propane at the manifold.
• DO NOT INSTALL AN ADDITIONAL REGULATOR WHERE THE OVEN CONNECTS TO THE GAS SUPPLY UNLESS THE INLET PRESSURE IS ABOVE MAXIMUM.
• Before connecting the oven, gas lines should be thoroughly purged of all metal filings, shavings, pipe dope, and other debris. After connection, the oven should be checked for correct gas pressure.
• The oven and its shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures over 1/2 psig (13.85” W.C., 3.45 kPa).
• The oven must be isolated from the gas supply piping system by closing its manual shutoff valve during any pressure testing of the gas piping system at test pressures equal to or less than 1/2 psig (13.85” W.C., 3.45 kPa).

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 quickly connect.

The restraint (i.e.: heavy gauge cable) should be a 1,000 lb. (453 kg) test load and should be attached without damaging the building. DO NOT use the gas piping or electrical conduit for the attachment of the permanent end of the restraint! Use anchor bolts in concrete or cement blocks. On wooden walls, drive hi-test wood lag screws into the studs of the wall.

1. Mount the supplied bracket to the leg bolt just below the gas inlet.
2. Attach the clip-on restraining cable to the mounting bracket.

Electrical Connection
Wiring diagrams are located in the control compartment and on the back of the oven.

This oven is supplied for connection to 115-volt grounded circuits. The electric motor, indicator lights and related switches are connected through the 6’ electric supply cord found at the rear of the oven.

WARNING: This appliance is equipped with a three-prong grounding type plug for your protection against shock hazards and should be plugged directly into a properly grounded three-prong receptacle. DO NOT cut or remove the grounding prong from this plug.

The Blodgett Oven Company cannot assume responsibility for loss or damage suffered as a result of improper installation.

The oven’s main burner lights and the Oven Heating Light comes on. With the main burner on, check the following.

1. Verify there are no gas leaks, by checking all gas connections with a soapy water solution.
2. Verify that the inlet pressure is correct. The inlet pressure can be checked at the pressure tap located on the combination valve’s inlet side.
3. Verify that the manifold pressure is correct. The manifold pressure can be checked at the pressure tap lo-cated on the combination valve’s outlet side.
4. If the above pressure readings are set to the recommended pressure requirements, allow the oven to burn off for 2 hours. If the pressure readings are not set correctly, turn off the oven and readjust accordingly.

WARNING: The break-in procedure burns off excess oils present in the metals during fabrication. Smoke may be produced. Proper ventilation is required.

Adjustments associated with initial installation
Each oven, and its parts, have been thoroughly tested and inspected before shipment. However, it is often necessary to further test or adjust the oven as part of a normal and proper installation. These adjustments are the responsibility of the installer or dealer. Since these adjustments are not considered defects in material or workmanship, they are not covered by the Original Equipment Warranty. They include, but are not limited to:

• calibration of the thermostat
• adjustment of the doors
• burner adjustments
• levelling
• testing of gas pressure
• tightening of fasteners.

No installation should be considered complete without proper inspection, and if necessary, adjustment by qualified installation or service personnel. The information contained in this section is provided for the use of qualified operating personnel. Qualified operat-ing personnel are those who have carefully read the information contained in this manual, are familiar with the functions of the oven and/or have had previous experi-ence with the operation of the equipment described.

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 tem-perature to offset the drop in temperature when the doors are opened and the cold product is loaded into the oven. Set the thermostat to the cooking temperature after the product is loaded.

NOTE : For frozen products, preheat the oven 100°F (56°C) above the cooking 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 centre is raw, or if there is colour variation, reduce the thermostat setting another 15-25°F (10-15°C). Continue to reduce the cooking temperature on successive loads until the desired results are achieved.

NOTE : Cooking at excessive temperatures will not reduce cooking 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 the best results for future reference.

NOTE : Cook time will vary with the amount of product loaded, the type of pan and the temperature.

General Guidelines for Operating Personnel

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 bak-ing 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 tem-perature.
2. Load the oven with the 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 shortens the bulb life considerably.

Painted and stainless steel ovens may be kept clean and in good condition with a light oil.

1. Saturate a cloth, and wipe the oven when it is cold.
2. Dry the oven with a clean cloth.

On the stainless front or interiors, deposits of baked-on splatter may be removed with any non-toxic industrial stainless steel cleaner. Heat tint and heavy discolouration may be removed with any non-toxic commercial oven cleaner.

1. Apply cleaners when the oven is cold. Always rub with the grain of the metal.

The porcelain interior can be cleaned with any commercial oven cleaner. Be sure caustic cleaning compounds DO NOT come in contact with the blower wheel and the aluminized steel panel directly behind it.

1. Remove the oven racks, the left and right side rack supports, the blower wheel cover and the blower wheel from the oven.
2. Soak the parts in a solution of ammonia and water.
3. Reinstall after cleaning.

NOTE : If the oven is moved the restraint must be reconnected after the unit is returned to its regular position.

Maintenance

Cleaning and Preventative Maintenance

Weekly Cleaning
In addition to the daily cleaning, it is necessary to clean the air intakes, such as the blower motor, rear cooling fan and fan guard every week. Air intakes provide necessary cooling air to the internal components. They are generally located on the rear and sides of the equipment.

NOTE : If the oven is moved the restraint must be reconnected after the unit is returned to its regular position.

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.
