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
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 equip-
ment replacement
• a wider range of menu choices
• a simplied cleaning process
The work process is simplied since products are pre-
pared 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 efciently;
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 (212ºF), 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 two speed fan, which is guarded against accidental
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 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. 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.

adjustable legs.
All motor bearings are permanently lubricated by the
manufacturer; there is no need for additional lubrication
during the operational lifetime of the motors.
VENTILATION
The necessity for a properly designed and installed ventilation system cannot be over emphasized. The ventilation
system will allow the unit to function properly while removing unwanted vapors and products of combustion from
the operating area.
The appliance must be vented with a properly designed
mechanically driven exhaust hood. The hood should be
sized to completely cover the equipment plus an overhang of at least 6” (15 cm) on all sides not adjacent to a
wall. The capacity of the hood should be sized appropri-
ately and provisions made for adequate makeup air.
WARNING!!
Failure to properly vent the oven can be hazardous to the health of the operator; and will
result in operational problems, unsatisfactory
baking, and possible damage to the equipment. Damage sustained as a direct result of
improper ventilation will not be covered by the
Manufacturer’s warranty.
When installed in the Commonwealth of Massachusetts,
this appliance must be interlocked with the hood exhaust
system so that the appliance may be operated only
when the hood exhaust system is running.

BC-20G only
U.S. and Canadian Installations
A power cord (115V or 230V) 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 GF-
CIs are more sensitive than others. Blodgett has qualied the Pass and Seymour brand, part number 2095,
20 A, 125 VAC, 60 Hz, specication grade GFCI duplex
receptacle as being immune to the variable frequency
inverter drive’s noise. Blodgett recommends using this
specic 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 sufcient 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 natu-
ral 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 total.
Previous Total 230,000 BTU
BC-20G 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’ (6m) 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 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
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 sufcient 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 specied 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 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).
Prior to connecting the appliance, gas lines should be
thoroughly purged of all metal lings, shavings, pipe
dope, and other debris. After connection, the appliance
must be checked for correct gas pressure.

Uses for Steam On Demand:
Most of the ideas came from our creative customers. Experiment with this feature on your own and let us know of
any new uses.
• Add a minute or two at the beginning when baking
bread for a shiny crust.
• Kick start large loads such as 20 or more chickens.
By starting large loads with 5 to 8 minutes of steam
you help the oven recover and cut the cooking time
by more than 10%.
2. Rotate the knob to enter the desired nal cook temperature in the display.
3. Insert the core probe into the product. Load product
into the oven and close the door. Be sure that the
terminal end of the core probe is outside of the oven
and clear of the door.
4. Connect the core probe to the PROBE CONNECTION (15) at the bottom of the control.
5. The display gives the actual core probe temperature
by pressing the TIMER/PROBE knob (8) again.
6. When the product reaches the nal cook temperature
the buzzer sounds.
• Bake bagels without boiling. By starting raw bagels
with 1 to 2 minutes of steam you can achieve a
beautiful crust.
• Cream caramel is great at 230ºF to 250ºF in the
Combi mode using 2 minutes of on demand steam.
• When cooking chicken wings, try setting the oven
in the Combi mode at 375ºF and use 3 minutes of
Steam On Demand. This method will stop the tips
from burning. Total cooking time is approximately 12
minutes.
• Pork ribs tend to pull off the bone better when using
5 to 8 minutes of Steam On Demand. Try ribs in the
Combi mode at 350ºF.

Maintenance
Spray Bottle Operating Procedure
NOTE: Only use a commercial oven cleaner/degreaser
with the spray bottle. DO NOT use chemicals that
are not intended as oven cleaners. See chemical
manufacturer’s information for intended use.
1. Unscrew the sprayer head and ll the container to
the MAX mark. Screw the head assembly on rmly
to ensure an airtight seal. The liquid must be clean
and free from foreign matter. Do not overll - space
must be left for compressing air.
Figure 7
2. To build up pressure, pump approximately 20 full
strokes when the container is lled with liquid. The
higher the pressure, the ner the spray. If the container is only partially lled, then more pumping is required to compress the additional air space.
Figure 9
4. Adjust spray nozzle for a wide spray pattern.
5. After a period of spraying, the pressure will drop. Restore the pressure by operating the air pump.
6. Release pressure after use by inverting the spray
head and depressing the trigger or by slowly unscrewing the spray head assembly which will allow
air to escape from around the lling aperture.
7. After use, rinse the spray bottle with clean water and
check that the hole in the nozzle is perfectly clean
and clear. Warm water (not hot) used with a household detergent is a useful cleaning agent for this purpose.
Figure 8
3. To spray, depress the trigger with your thumb.
NOTE: Further information can be found in the in-
struction leaet supplied with your spray bot-
tle.
WARNING!!
Protective clothing and eyewear should be
worn while using cleaning and deliming
agents.
To order additional bottles or spray heads use the following part numbers:
Complete Spray Bottle - P/N R0006
Spray Head Repair Kit - P/N R6332

DAILY CLEANING
Cleaning the Interior
Daily cleaning of the oven is essential for sanitation, and
to ensure against operational difculties. The stainless
steel cavity may corrode with improper cleaning of the
oven. Use an oven cleaning detergent in conjunction with
the supplied spray bottle.
For difcult cleaning, allow the spray-on oven cleaner to
work longer before rinsing.
1. Open the oven door. Place the oven in cool down
mode. Let the oven cool to below 140ºF (60ºC).
2. Fill the spray bottle with a mild oven detergent. DO
NOT use abrasive cleaners on your Blodgett
Combi. Be sure to follow the MSDS or safety instructions on the bottle of your oven cleaner. We
recommend the following cleaners:
Greasecutter Plus by Ecolab
EZ Clean by Cellow
Advance Oven Cleaner by Diversey-Lever
3. Pump the bottle twenty times to build up pressure.
The higher the pressure, the ner the spray. Spray
the oven interior. Turn the nozzle to adjust the spray
pattern.
Maintenance
Cleaning and Preventive Maintenance
Cleaning the Exterior
The exterior of the appliance may be cleaned and kept in
good condition with a light oil. Saturate a cloth and wipe
the appliance when it is cold; wipe dry with a clean cloth.
WARNING!!
DO NOT spray the outside of the oven with
water or clean with a water jet. Cleaning with
a water jet can impregnate chlorides into the
stainless steel, causing the onset of corrosion.
Clean the air intake / cooling fan behind the oven so that
it is free of all lint, grease or other inhibitors of air ow.
Keeping this area free of obstruction will extend the life of
the components.
PREVENTIVE MAINTENANCE
The best preventive maintenance measures are the
proper initial installation of the equipment and a program
for cleaning the appliance routinely. The Oven/Steamer
requires no lubrication. Contact the factory, the factory
representative or a local Blodgett Combi service company to perform maintenance and repairs should they be
required.
4. Close the door. Place the oven in steam mode for 10
minutes.
5. When nished steaming, open the door and rinse the
interior with the attached spray hose.
Figure 10
6. Leave the door open overnight to vent the oven. If the
oven will not be used for an extended period of time,
place the oven in hot air mode to dry.
