Introduction

The Blodgett CombiĆOven/Steamer

The Blodgett CombiĆOven/Steamer offers a comĆ

pletely new method of cooking. With the Oven/

Steamer you have the choice of two cooking proĆ

cesses: Steam and Hot Air, either...

D Separately

D Combined, or

D In Sequence

And for easy operation you can choose from three

modes:

Steam Hot Air

Combi

Steam &

Hot Air

In the Steam mode you can:

steam reheat reconstitute

stew thaw simmer

blanch 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 steaming

You āācan also āāuse āātwo āāor āthree functions in seĆ

quence during one cooking process. We call this:

D combiĆsteaming

D combiĆroasting

D combiĆbaking

The combination of circulating hot air and steam

in the space saving, high performance CombiĆ

Oven/Steamer leads to improvements in the folĆ

lowing areas:

D increased productivity in the kitchen

D a reduction in capital expenditures for multiple

equipment replacement

D a wider range of menu choices

D a simplified cleaning process

The work process is simplified since products are

prepared on or in steam table āpans āand trays.

Food can be cooked, stored, and transported with

āthe āsame āāpans. āSmall āamounts of product can be

processed efficiently; preĆcooked and conveĆ

nience foods can be reheated within minutes.

āMany frozen foods can be processed without preĆ

thawing. This flexibility 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 imĆ

portant than ever. Vegetables are cooked in the

Blodgett CombiĆOven/Steamer without water at

the optimal temperature of just under 100_C

(212_F), maintaining valuable vitamins, minerals,

nutrients and trace elements. Cooking meat in the

Combi results in less shrinkage and a firmer, juicier

product. The Blodgett CombiĆOven/Steamer is

being used more and more for baking. Steam and

Hot āAir āmodes āmake āit āa āgeneral āpurpose baking

appliance.

Introduction

Description of the CombiĆOven/Steamer

ABOUT THE OVEN/STEAMER

Blodgett CombiĆOven/Steamers are quality proĆ

duced using highĆgrade stainless steel with first

class workmanship.

The two speed fan, which is guarded against acciĆ

dental finger contact, is driven by a quiet and powĆ

erful 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 excesĆ

sive heat radiation and saves energy.

The high performance fresh steam generator with

its control system makes it possible to enjoy all of

the advantages of a high quality steamer at the

flick of a switch. Fresh steam enters the oven cavĆ

ity without pressure and is circulated at high

speed. This process enables quick and gentle

cooking and ensures high quality food while proĆ

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 simĆ

ple arrangement of the controls. Graphic symbols

make the appliance easy for even inexperienced

kitchen staff to operate. Steam, Hot Air and Combi

modes can be selected with one switch. The

Steam On Demand feature allows the operator to

add steam at any time for up to 8 minutes while opĆ

erating in either the hot air or Combi modes. This

feature is excellent for baking as well as roasting

operations. A fourth function on the mode selecĆ

tion switch, the Cool Down mode, allows the oven

cavity to cool down rapidly with the door opened.

The steam on demand function allows the operaĆ

tor the ability to introduce steam into the cooking

process at any time.

Cleaning is kept to a minimum. The interior is

sprayed with a selfĆacting 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.

Installation

Gas Connections

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 BCĆ20G 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 toĆ

tal.

Previous Total 230,000 BTU

BCĆ20G (for hot air) 125,000 BTU

New Total 355,000 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 20' (6 m) and the pipe size

is 1" (2.54 cm).

4. Use the appropriate table to determine the toĆ

tal capacity of your current gas piping.

The total capacity for this example is 465,000

BTU. Since the total required gas pressure,

355,000 BTU is less than 465,000 BTU, the

current gas piping will not have to be inĆ

creased.

NOTE: The BTU capacities given in the tables are

for straight pipe lengths only. Any elbows

or other fittings will decrease pipe capaciĆ

ties. For example: a schedule 40Ć1/2" elĆ

bow fitting has an equivalent cpapacity of

4.2" (10.2 cm) of straight pipe. 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 sufĆ

ficient 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 operate with the type of gas specified on the ratĆ

ing plate attached to the right side of the apĆ

pliance.

Each oven is supplied with a regulator to maintain

the proper gas pressure. The regulator is essenĆ

tial 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).

Prior to connecting the appliance, gas lines

should be thoroughly purged of all metal filings,

shavings, pipe dope, and other debris. After conĆ

nection, the appliance must be checked for corĆ

rect gas pressure.
