The Blodgett Combi-Oven/Steamer

The Blodgett Combi-Oven/Steamer offers a completely
new method of cooking. With the Oven/Steamer you have
the choice of two cooking processes: Steam and Hot Air,
either...

• Separately

• Combined, or

• In Sequence

And for easy operation you can choose from three modes:

In the Steam mode you can:

steam reheat reconstitute
stew thaw simmer
blanche preserve braise
poach

In the Hot Air mode you can:

roast bake grill
gratinate broil

In the Combination Steam and Hot Air mode you can:

defrost roast rethermalize
reheat bake forced steam

NOTE: CNVX models only operate in hot air mode.

You can also use two or three functions in sequence

during one cooking process. We call this:

• combi-steaming

• combi-roasting

• combi-baking

The combination of circulating hot air and steam in the
space saving, high performance Combi-Oven/Steamer
leads to improvements in the following areas:

• increased productivity in the kitchen

• a reduction in capital expenditures for multiple equip­ment replacement

• a wider range of menu choices

• a simplied cleaning process

The work process is simplied since products are pre­pared on or in steam table pans and trays. Food can be
cooked, stored, and transported with the same pans.

Small amounts of product can be processed efciently;

pre-cooked and convenience foods can be reheated with­in minutes. Many frozen foods can be processed with-

out pre-thawing. This exibility in preparation reduces the

need for kettles and steam tables since there is no need
for large amounts of food to be kept warm for long periods
of time.

Today the improvement of food quality is more important

than ever. Vegetables are cooked in the Blodgett Combi­Oven/Steamer without water at the optimal temperature
of just under 100ºC (21ºF), maintaining valuable vita­mins, minerals, nutrients and trace elements. Cooking

meat in the Combi results in less shrinkage and a rmer,

juicier product. The Blodgett Combi-Oven/Steamer is be­ing used more and more for baking. Steam and Hot Air
modes make it a general purpose baking appliance.

Description of the Combi-Oven/Steamer

ABOUT THE OVEN/STEAMER

Blodgett Combi-Oven/Steamers are quality produced us­ing high-grade stainless steel with rst class workman-

ship.

The multiple speed fan, which is guarded against acci-

dental nger 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.

The use of high quality insulation impedes excessive heat

radiation and saves energy.

The Oven/Steamer has optional adjustable legs which

adapt easily to slightly uneven surfaces and optional oor

stands which are designed for use with all of the table
models.

The high performance fresh steam generator with its con­trol system makes it possible to enjoy all of the advantag-

es of a high quality steamer at the ick of a switch. Fresh

steam enters the oven cavity without pressure and is cir-

culated at high speed. This process enables quick and
gentle cooking and ensures high quality food while pro-

viding convenient working methods. The steam generator
is completely automatic and protected from running dry.

OVEN/STEAMER OPERATION

The practical oven door, with a viewing window, has a
wide swing radius and handle which can be operated eas­ily, even with wet or greasy hands.

Ease of operation is guaranteed through the simple ar­rangement of the controls. Graphic symbols make the ap­pliance easy for even inexperienced kitchen staff to oper­ate. The Steam On Demand feature allows the operator
to add steam at any time while operating in either the Hot
Air or Combi modes. This feature is excellent for baking
as well as roasting operations. A fourth function, the Cool
Down mode, allows the oven cavity to cool down rapidly
with the door opened.

Cleaning is kept to a minimum. The interior is sprayed
with a self-acting cleaning solution which interacts with
steam to easily remove crusts and stains. The oven is
designed for easy care and is welded water tight so that
the internal cooking cavity may be rinsed with a hose after
the steam cleaning process.

ELECTRICAL CONNECTION

All Models

NOTE: Electrical connections must be performed by a

qualied installer only.

Before making any electrical connections to these appli-

ances, check that the power supply is adequate for the
voltage, amperage, and phase requirements stated on

the rating name plate mounted on the appliance.

The circuit breaker that is used to provide power to this
appliance must have a minimum of .076” (3mm) contact
spacing. The circuit breaker must meet all Local and Na­tional installation standards.

All appliances must be installed in accordance with Local
or National Electrical codes.

A wiring schematic is located on the inside of the remove­able side panel.

NOTE: Disconnect the power supply to the appliance

before servicing.

WARNING!!

Improper installation may invalidate your war­ranty.

Electric Models

A strain relief for the power supply cord is provided. The
installer must supply a cord that meets all Local and Na­tional installation standards.

Gas Models

U.S. and Canadian Installations

A power cord (115V units only) is supplied with a plug at­tached. Plug the power cord into the desired receptacle.

This oven model uses a variable frequency inverter drive.
Appliances that use variable frequency inverter drives
produce high frequency noise and require lters and

shielded motor cabling. This causes higher leakage cur­rent toward Earth Ground. Especially, at the moment of
switching ON this can cause an inadvertent trip of the ap­pliance’s ground fault interrupter (GFCI). Some GFCIs

are more sensitive than others. Blodgett has qualied

the Pass and Seymour brand, part number 2095, 20 A,

125 VAC, 60 Hz, specication grade GFCI duplex recep­tacle as being immune to the variable frequency inverter
drive’s noise. Blodgett recommends using this specic

GFCI for this model oven.

WARNING!!

If the supply cord is damaged, it must be re­placed by a special cord or assembly available
from the manufacturer or its service agent.

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 sufcient 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 BCX-14G 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

BCX-14G 115,000 BTU

New Total 345,000 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 375,000 BTU. Since

the total required gas pressure, 345,000 BTU is less than

375,000 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

ttings will decrease pipe capacities. Contact

your local gas supplier if you have any ques­tions.

PRESSURE REGULATION AND TESTING

The gas pressure to the appliance must be rated for each
appliance while the burners are on. A sufcient gas pres­sure must be present at the inlet to satisfy these condi­tions. Refer to the table below for correct gas pressure.

Each appliance has been adjusted at the factory to oper-

ate with the type of gas specied on the rating plate.

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.

DO NOT INSTALL AN ADDITIONAL REGULATOR
WHERE THE UNIT CONNECTS TO THE GAS SUPPLY
UNLESS THE INLET PRESSURE IS GREATER THAN
14” W.C. (1/2 PSI) (37mbar).

The oven and its individual shutoff valve must be discon­nected from the gas supply piping system during any
pressure testing of that system at test pressures in ex­cess of 1/2 psig (3.45kPa).

The oven must be isolated from the gas supply piping
system by closing its individual manual shutoff valve dur­ing any pressure testing of the gas piping system at test

pressures equal or less than 1/2 psig (3.45kPa).

Installation

Gas Hose Restraint

If the appliance is mounted on casters, a commercial ex­ible connector with a minimum of 3/4” (1.9 cm) inside di-

ameter must be used along with a quick connect device.

A restraint must be used to limit the movement of the ap­pliance so that no strain is placed upon the exible con­nector. The restraint should be fastened to the base frame

of the oven as close to the exible connector as possible.

It should be short enough to prevent any strain on the
connector. With the restraint fully stretched the connector

should be easy to install and quick connect.

The restraint (ie: heavy gauge cable) 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 block. On wooden walls, drive hi test wood lag
screws into the studs of the wall.

WARNING!!

If the restraint is disconnected for any reason
it must be reconnected when the appliance is
returned to its original position.

U.S. and Canadian installations

The connector must comply with the Standard for Con­nectors for Movable Gas Appliances, ANSI Z21.69 or
Connectors For Moveable Gas Appliances CAN/CGA-

6.16 and a quick disconnect device that complies with the

Standard for Quick-Disconnect Devices for Use With Gas
Fuel, ANSI Z21.41 or Quick Disconnect For Use With Gas

Fuel CAN 1-6.9. Adequate means must be provided to

limit the movement of the appliance without depending

on the connection and the quick disconnect device or its

associated piping.

A drip leg must be used at each appliance. Refer to
NFPA54/ANSI Z223.1 - Latest Edition (National Fuel Gas
Code) for proper drip leg installation.

General export installations

Installation must conform with Local and National instal-

lation standards. Local installation codes and/or require­ments may vary. If you have any questions regarding the

proper installation and/or operation of your appliance,
please contact your local distributor. If you do not have a
