The Blodgett Combi-Oven/Steamer
The Blodgett Combi-Oven/Steamer offers a com-
pletely new method of cooking. With the Oven/
Steamer you have the choice of two cooking pro-
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 can also use tw o or three functions in se-
quence during one cooking process. We call this:
D combi-steaming
D combi-roasting
D combi-baking
The combination of circulating hot air and steam
in the space saving, high performance Combi-
Oven/Steamer leads to improvements in t he fol-
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 pans and trays.
F ood can be cooked, stored, and transported with
the same pans. Small amounts of product can be
processed efficiently; pre-cooked and conve-
nience foods can be reheated within minutes.
Many frozen foods can be processed without pre-
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 im-
portant than ever. Vegetables are cooked in the
Blodgett Combi-Oven/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 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 pro-
duced using high-grade stainless steel with first
class workmanship.
The two speed fan, which is guarded against acci-
dental finger contact, is driven by a quiet and pow -
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 exces-
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 cav-
ity without pressure and is circulated 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 sim-
ple arrangement of the controls. Graphic symbols
make the a ppliance easy for even inexperienced
kitchen staff to operate. Steam, Hot A ir 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 op-
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 selec-
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 opera-
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 self-acting cleaning solution which
interacts w ith steam to easily remove crusts and
stains. The oven is designed for easy care and is
welded water t ight so that the internal cooking
cavity may be rinsed with a hose after the steam
cleaning process.

Gas Connections
GAS PIPING
A properly sized gas supply s ystem 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 BC-20G 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 to-
tal.
Previous Total 230,000 BTU
BC-20G (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
thepipelengthis20’(6m)andthepipesize
is 1” (2.54 cm).
4. Use t he appropriate table to determine the to-
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 in-
creased.
NOTE: The BTU capacities given in the tables are
for straight pipe lengths only. Any elbows
or other fittings will decrease pipe capaci-
ties. For example: a schedule 40-1/2” el-
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.

Each appliance has been adjusted at the factory
to operate with the type of gas specified on the rat-
ing plate attached to the right side of the ap-
pliance.
Each oven is supplied with a regulator to maintain
the proper gas pressure. The regulator is essen-
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 t est
pressuresinexcessof1/2psig(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 con-
nection, the appliance must be checked for cor-
rect gas pressure.
