The Bl dgett C mbiĆOven/Steamer
The Blodgett CombiĆOven/ teamer offers a comĆ
pletely new method of cooking. With the Oven/
teamer you have the choice of tw c king pr Ć
cesses: Steam and H t Air, either...
DSeparately
DC mbined, r
DIn Sequence
And for easy operation you can choose from three
modes:
team Hot Air Combi
team &
Hot Air
In the Steam mode you can:
steam reheat reconstitute
stew thaw simmer
blanch preserve braise
poach
In the H t Air mode you can:
roast bake
grill gratinate
broil
In the C mbinati n, Steam, and H t 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:
DcombiĆsteaming
DcombiĆroasting
DcombiĆbaking
The combination of circulating hot air and steam
in the space saving, high performance CombiĆ
Oven/ teamer leads to improvements in the folĆ
lowing areas:
Dincreased productivity in the kitchen
Da reduction in capital expenditures for multiple
equipment replacement
Da wider range of menu choices
Da 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. ā mall 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/ teamer 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/ teamer is
being used more and more for baking. team and

Descripti n f the C mbiĆOven/Steamer
ABOUT THE OVEN/STEAMER
Blodgett CombiĆOven/ teamers 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. team, Hot Air and Combi
modes can be selected with one switch. The
team 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.

LOCATION
The well planned and proper placement of your
appliance will result in long term operator conveĆ
nience and satisfactory performance.
The following clearances must be maintained beĆ
tween the unit and any combustible or nonĆcomĆ
bustible construction.
BCĆ20G
DRight side of unit - 6" (15 cm)
DLeft side of unit - 6" (15 cm)
DBack of unit - 6" (15 cm)
The following clearances are recommended, but
not required, for servicing.
DLeft side of unit - 12" (30 cm)
DBack of unit - 12" (30 cm)
Place the unit in an area which is free of drafts and
accessible for proper operation and servicing.
Keep the operating area free and clear of all comĆ
bustibles such as paper, cardboard, and flamĆ
mable liquids and solvents.
DO NOT place the unit on a curb base or seal to
the wall; either condition will prevent proper ventiĆ
lation to the blower motors. light unevenness can
be corrected with the 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 inĆ
stalled ventilation system cannot be over emphaĆ
sized. The ventilation system will allow the unit to
function properly while removing unwanted vaĆ
pors and products of combustion from the operatĆ
ing area.
The appliance must be vented with a properly deĆ
signed 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 appropriately and proviĆ
sions made for adequate makeup air.
WARNING!!
Failure t pr perly vent the ven can be

Gas M dels
U.S. and Canadian Installati ns
A power cord (115V or 230V) is supplied with a
plug attached. Plug the power cord into the deĆ
sired receptacle.
This oven model uses a variable frequency invertĆ
er drive. Appliances that use variable frequency
inverter drives produce high frequency noise and
require filters 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 apĆ
pliance's ground fault interrupter (GFCI). ome
GFCIs are more sensitive than others. Blodgett
has qualified the Pass and eymour brand, part
number 2095, 20 A, 125 VAC, 60 Hz, specification
grade GFCI duplex receptacle as being immune to
the variable frequency inverter drive's noise. BlodĆ
gett recommends using this specific GFCI for this
model oven.
WARNING!!
If the supply c rd is damaged, it must be
replaced by a special c rd r assembly
available fr m the manufacturer r its serĆ
vice agent.

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 value in the following example are
for natural ga .
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. ince 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 capacitie given in the table are
for traight pipe length only. Any elbow
or other fitting will decrea e pipe capaciĆ
tie . For example: a chedule 40Ć1/2" elĆ
bow fitting ha an equivalent cpapacity of
4.2" (10.2 cm) of traight pipe. Contact
your local ga upplier if you have any
que tion .

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.
