Introduction
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 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 two or three functions in sequence 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 CombiOven/Steamer leads to improvements in the following 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.
Food can be cooked, stored, and transported with
the same pans. Small amounts of product can be
processed efficiently; pre-cooked and convenience foods can be reheated within minutes.
Many frozen foods can be processed without prethawing. 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 important 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.

Introduction
Description of the Combi-Oven/Steamer
ABOUT THE OVEN/STEAMER
Blodgett Combi-Oven/Steamers are quality produced using high-grade stainless steel with first
class workmanship.
The two speed fan, which is guarded 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.
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 floor stands which are designed for use
with all of the table models.
BC14E and BC14G only
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 cavity without pressure and is circulated at high
speed. This process enables quick and gentle
cooking and ensures high quality food while providing 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. 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 operating 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 selection switch, the Cool Down mode, allows the oven
cavity to cool down rapidly with the door opened.
The steam on demand function allows the operator 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 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.

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 BC14G 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
BC14G 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
thepipelengthis30’(9m)andthepipesize
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 fittings will decrease pipe capacities. For example: a schedule 40 1-1/2” ell
fitting has an equivalent capacity 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 sufficientgaspressuremustbepresentattheinletto
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 rating plate attached to the right side of the appliance.
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 test
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 connection, the appliance must be checked for correct gas pressure.

Gas Hose Restraint
If the appliance 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.
A restraint must be used to limit the movement of
the appliance so that no strain is placed upon the
flexible connector. The restraint should be fastened to the base frame of the oven as close to the
flexible 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 QuickDisconnect 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.
