The Blodgett Combi Cooki g Li e
For quite some time, commercial cooking equipĆ
ment has remained more or less unchanged.
There are kettles, deck ovens, the good old range
with its legion of pots āand āmany āother āextra
āappliances. The result: time expenditure, excesĆ
sive manual work, and countless cleaning proĆ
cesses. The last āāāfew āāāyears āāhave āāpaved āāthe āāway āāfor
āa revolution in the equipment of restaurant and inĆ
stitutional kitchens. Blodgett Combi is proud to ofĆ
fer three different cooking platforms, one of which
is sure to match your needs. The Blodgett Combi
line includes:
DThe Blodgett Combi Co vectio Steamer
DThe Blodgett Combi Co vectio Ove
DThe Blodgett CombiĆOve /Steamer
All Blodgett Combi appliances improve your kitchĆ
en through:
Dincreased productivity
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.
COMBI CONVECTION STEAMER
teaming is a well known cooking process freĆ
quently used in restaurant and institutional kitchĆ
ens. With the Combi Convection teamer, it is now
possible to enjoy the many advantages of steamĆ
ing including shorter cook times, higher product
quality and vitamin retention.
The Combi Convection teamer includes a built in
steam generator. This unit includes an inlet, funnel
assembly and valve lever for decalcification.
COMBI CONVECTION OVEN
Cooking in the Combi Convection Oven differs
from cooking in a traditional deck or range oven
since heated air is constantly recirculated over the
product by a fan in an enclosed chamber. The
moving air continually strips away the layer of cool
air surrounding the product, quickly allowing the
heat to penetrate. The result is a high quality prodĆ
uct, cooked at a lower temperature in a shorter
amount of time.
COMBIĆOVEN/STEAMER
With the Oven/ teamer you have the choice of two
cooking processes: team and Hot Air, either...
Deparately
DCombined, or
DIn equence using two or three functions during
one cooking process. We call this combiĆsteamĆ
ing and combiĆbaking.
For easy operation you can choose from three
modes:
team Hot Air Combi
team &
Hot Air
In the team mode you can:
DĂsteam DĂblanch DĂpoach
DĂdefrost DĂrethermalize
In the Hot Air mode you can
DĂroast DĂbake DĂbraise
In the Combi mode you can:
DĂdefrost DĂroast DĂrethermalize
DĂreheat DĂbake DĂsous vide*
DĂproof* DĂcook & hold*
* with optional digital controls
The CombiĆOven/ teamer is offered in two models,
each with different steam producing systems.
DThe CO Ć8G model includes a built in steam
generator. This unit includes an inlet, funnel asĆ
sembly and valve lever for decalcification.
DThe CO Ć8GD is a direct steam unit that is
connected to an external steam source.

Descriptio of the Blodgett Combi Cooki g Li e
ABOUT THE COMBI LINE
Blodgett Combi appliances are quality produced
using highĆgrade stainless steel with first class
workmanship.
The use of high quality insulation impedes excesĆ
sive heat radiation and saves energy.
Optional adjustable legs adapt easily to slightly
uneven surfaces. Optional floor stands have been
designed for use with all of the table models.
Ove /Steamers a d Co vectio Steamers
The high performance steam 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
product while providing convenient working methĆ
ods.
A patented quench system keeps the air in the unit
clean. Fumes are extracted from the appliance,
quenched, and directed out through the condensĆ
er drain. The exhaust system is effective in all
cooking modes and results in better quality foods
and o flavor tra sfer. The 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. CondensaĆ
tion and waste water, which result during steamĆ
ing and cleaning, are continuously drained.
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 appliances easy for even inexperienced
kitchen staff to operate. All modes can be selected
with one switch. This includes the Cool Down
mode, which allows the oven cavity to cool down
rapidly with the door opened or closed.
Cleaning is kept to a minimum. The interior can be
sprayed with a cleaning solution 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
cleaning process.

Place the unit in an area which is free of drafts and
accessible for proper operation and servicing.
Keep the oven area free and clear of all combusĆ
tibles such as paper, cardboard, and flammable
liquids and solvents.
DO NOT place the oven 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.
The air vents on the left side of the unit must be
protected from heat and steam or water sources.
Consult the factory for an optional protective side
heat shield kit if excessive ambient heat or steam
is present on the left side of the unit.
DCO Ć8G heat shield P/N R4514
DCO Ć8GD heat shield P/N R4514
DBC Ć8G heat shield P/N R4514
DCNVĆ8G heat shield P/N R4514
On all models, tripping the blower motor's thermal
overload device indicates an excessive ambient
temperature at the back of the oven. This must be
corrected to prevent permanent damage to the
oven. All motor bearings are permanently lubriĆ
cated by the manufacturer; there is no need for
additional lubrication during the operational lifeĆ
time 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.

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 ollowing example are
or natural gas.
You purchase a CO Ć8G 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
CO Ć8G (for steam) 90,000 BTU
New Total 320,000 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 30' (9 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 375,000
BTU. ince the total required gas pressure,
320,000 BTU is less than 375,000 BTU, the
current gas piping will not have to be inĆ
creased.
NOTE: The BTU capacities given in the tables are
or straight pipe lengths only. Any elbows
or other ittings will decrease pipe capaciĆ
ties. For example: a schedule 40 1Ć1/2" ell
itting has an equivalent capacity o 4.2"
(10.2 cm) o straight pipe. Contact your loĆ
cal gas supplier i you have any questions.

PRESSURE REGULATION AND TESTING
The gas pressure to the appliance must be rated
for 7" W.C. for natural gas and 12-14" W.C. for
propane gas for each unit while the burners are
on. A sufficient gas pressure must be present at
the inlet to satisfy these conditions.
Each unit has been adjusted at the factory to operĆ
ate with the type of gas specified on the rating
plate attached to the right side of the unit.
Each oven is supplied with a regulator to maintain
the proper gas pressure. The regulator is esse Ć
tial to the proper operatio of the ove a d
should ot be removed. It is preset to provide the
oven with 3.5" W.C. (0.87 kPa) for natural gas and
10.0" W.C. (2.50 kPa) for Propane while the flame
is on.

GREATER THAN 14" W.C. (1/2 P I)
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 unit, gas lines should be
thoroughly purged of all metal filings, shavings,
pipe dope, and other debris. After connection, the
unit should be checked for correct gas pressure.

Gas Hose Restrai t
If the unit 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.
The restraint, supplied with the appliance, must be
used to limit the movement of the unit 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 posĆ
sible. 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 atĆ
tached without damaging the building. DO NOT
use the gas piping or electrical conduit for the atĆ
tachment 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.
