The Blodgett Combi Cooking Line

For quite some time, commercial cooking equipment has remained more or less unchanged. There are kettles, deck ovens,thegoodoldrange with its legion of pots and many other extra appliances. The result: time expenditure, excessive manual work, and countless cleaning processes.Thelastfewyearshavepavedthe wayfor a revolutionin the equipment of restaurant and institutionalkitchens. Blodgett Combiis proud tooffer threedifferent cooking platforms,one of which is sure to match your needs. The B lodgett Combi line includes:

The Blodgett Combi Convection Steamer

The Blodgett Combi Convection Oven

The Blodgett Combi-Oven/Steamer

AllBlodgettCombiappliancesimproveyourkitchen through:

increased productivity

a wider range of menu choices

a simplified cleaning process

The work process is simplified since productsare prepared on or in steam table pans and trays. Foodcanbe cooked, stored,andtransportedwith the same pans. Small amounts of product can be processed efficiently; pre-cooked and convenience foods can be reheated within minutes.

COMBI CONVECTION OVEN

Cooking in the Combi Convection Oven differs from cooking in a traditional deck or range oven sinceheated airisconstantlyrecirculatedoverthe product by a fan in an enclosed chamber. The movingaircontinually strips awaythelayer ofcool air surrounding the product, quickly allowing the heatto penetrate. Theresultis ahighquality product, cooked at a lower temperature in a shorter amount of time.

Introduction

Description of the Blodgett Combi Cooking Line

ABOUT THE COMBI LINE

Blodgett Combi appliances are quality produced using high-grade stainless steel with first class workmanship.

The use ofhigh qualityinsulationimpedes excessive heat radiation and saves energy.

Optional adjustable legs adapt easily to slightly unevensurfaces. Optionalfloorstands have been designed for use with all of the table models.

Oven/Steamers and Convection Steamers

The high performance steam control system makes it possibleto enjoyall of the advantages of ahighquality steamerat the flick ofa switch.Fresh steamenters theovencavitywithout pressureand is circulated at high speed. This process enables quickandgentlecookingandensures highquality product while providing convenientworkingmethods.

Apatentedquenchsystemkeeps theairintheunit clean. Fumes are extracted from the appliance, quenched,anddirected outthrough thecondenser drain. The exhaust system is effective in all cooking modes and results in betterquality foods and no flavortransfer. The fan,which isguarded against accidental finger contact, is driven by a quiet and powerful motor. The condenser draws out excess steam from the appliance. Condensation and waste water, which result during steaming and cleaning, are continuously drained.

OPERATION

The practical oven door, with a viewing window, has a wide swingradiusa nd handlewhich can be operated easily, even with wet or greasy hands.

Ease of operation is guaranteed throughthe simplearrangementofthe controls. Graphic symbols make the appliances easy for even inexperienced kitchenstaff tooperate. Allmodescanbe selected with one switch. This includes the Cool Down mode, which allows the oven cavity to cool down rapidly with the door opened or closed.

Cleaningis kepttoa minimum.Theinterior canbe sprayed with a cleaning solution to easilyremove crusts and stains. The oven is designed for easy care and is welded w ater tight so that the internal cooking cavitymaybe rinsedwithahose afterthe cleaning process.

Location

Installation

The well planned and proper placement of your appliance will result in long term operator convenience and satisfactory performance.

The following clearances mustbe maintained be tween the unit and any combustible or non-combustible construction.

Oven body right side --- 4” (10 cm)

Oven body left side --- 4” (10 cm) with casters

12” (30 cm) without casters

Oven body back --- 4” (10 cm)

NOTE: For models with hose assemblies on the

back of the unit, the hose must be 4” (10

cm) from the wall.

If optional casters are not used, the following clearances are recommended for service.

Oven body left side --- 12” (30 cm)

Oven body back --- 12” (30 cm)

Place the unit in an area which is free of drafts and accessible for proper operation and 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 the wall;either condition will prevent proper ventilationtotheblowermotors.Slightunevennesscan be corrected with the adjustable legs.

Heat sources must not be located near the air vents on the left hand sideof theunit. Consult the factory for an optional protective side heat shield kit if a warm surface or water source is to the left of the unit. If excessive ambient temperature or a watersourceis presentaheat shieldmust beadded to the left hand side of the oven to protect the unit from excessive heat or water

CNV-8E heat shield P/N R9048

Onallmodels,trippingtheblower motor’sthermal overload device indicates an excessive ambient temperature at the side of the oven. This must be corrected to prevent permanent damage to the oven. All motor bearings are permanently lubricated by the manufacturer; there is no need for additional lubrication during the operational lifetime of the motors.

Final Check and Adjustments

BEFORESWITCHINGTHEAPPLIANCEON

Beforeapplyingpower to the unit for the first time, check for the following conditions:

All electrical safety provisions have been adhered to and the electrical connections are correct.

Water is connected, turned on and all of the connections are water tight.

NOTE: COS-8E and BCS-8E units only --- The

first time the unit is turned on, or after the unit has been OFF for 5 hours and then turned on, it will automatically flush the steam generator for a period of 75 seconds. The steam generator will then fill to the proper water level. The unit is now ready for operation.

DOOR ADJUSTMENT

The doorcatch maybeadjustedin two directions, in and out, and up and down, using the following procedure:

1. Adjust catch up and down by loosening the two bolts holding the catch to the face of the unit (A).

2. Make adjustments sothat the leading face of the catch is centered in the opening of the handle assembly.

3. Tighten the bolts so that there is no further movement.

4. Adjust catch in and out by loosening the bolt on the top of the catch (B).

5. Theadjustmentfaceis stepped sot hat movement is limited with the bolt tightened properly.

6. The adjustment is correct when the door closes firmly and no steam leaks from the gasket.

The hinges can also be adjusted as follows:

1. Be certain the catch is adjusted properly.

2. Adjust hinges so that the door back and the unit face are parallel (C).

3. The adjustment is correct when no steam leaks through the gasket and the door is very slightly compressing the gasket.
