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
There are four additional specialized modes to help you make the most of your time:
Retherm - for perfect reheating
Proong - Proof and bake all in the same oven
Preheat - in this mode the oven will preheat to 575ºF (300ºC) for 15 minutes. The oven will then automatically lower to 480ºF (249ºC) to protect the advanced elec­tronic components.
Cool Down - allows the oven cavity to cool down rapidly with the door opened
You can also use two or three functions in se-
quence 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 equip­ment replacement
a wider range of menu choices
a simplied cleaning process
The work process is simplied 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 efciently;
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 212ºF (100ºC), 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 Combis are quality produced using high-grade stainless steel with rst class workmanship.
The multiple speed fan, which is guarded against acci-
dental 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.
Fresh steam enters the oven cavity without pressure and
circulates at high speed. This process enables quick and gentle cooking and ensures high quality food while pro-

Figure 3
To facilitate cleaning and servicing, the oven should be
connected with an approved exible 3/4” hose. Perma­nent installations should be tted with a stop-tap and a
non-return valve.
Before connecting the oven to water, ush the tubes
thoroughly. Connect the oven.
DRAIN CONNECTION
Blodgett ovens are equipped with a drain system that re­moves surplus water from the oven chamber. This may be condensed water from the products, or it may occur when the oven chamber is cooled down with cold water, or when the oven chamber is cleaned.
WARNING!!
Connection must be carried out by an autho­rised plumber, to an open or closed drain. The drain must never end directly beneath the oven.
The drain must be of stainless steel or an equally
temperature-resistant material, have a fall of at least 3° or 5%. See page 4 for drain diameter.
BLCT-23, 6 and 10 Mini Combi models
1 water connection. Must meet the requirements ap­plying to water supplied to household appliances.

ELECTRICAL CONNECTION
NOTE: Electrical connections must be performed by a
qualied installer only.
Before making any electrical connections to these appli-
ances, check that the power supply is adequate for the voltage, amperage, and phase requirements stated on
the rating name plate mounted on the appliance.
1. The rating plate is located on the right side of the oven.
An approved plug outlet or a safety cutout must be locat­ed close to the oven so that the oven can be disconnected during installation and repair. The safety cutout must be able to cut off all poles with a total distance of break of at least 3 mm.
All appliances must be installed in accordance with Local or National Electrical codes.
The wiring diagram is located in the motor compartment.
NOTE: Disconnect the power supply to the appliance
before servicing.
WARNING!!
Improper installation may invalidate your war­ranty.
Electric Models
A strain relief for the power supply cord is provided. The installer must supply a cord that meets all Local and Na­tional installation standards.
Gas Models
U.S. and Canadian Installations
A power cord (115V units only) is supplied with a plug at­tached. Plug the power cord into the desired receptacle.
NOTE: The BLCT-202G must be hard wired.
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 GFCIs
are more sensitive than others. Blodgett has qualied the
Pass and Seymour brand, part number 2095, 20 A, 125
VAC, 60 Hz, specication grade GFCI duplex receptacle as being immune to the variable frequency inverter drive’s noise. Blodgett recommends using this specic 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.
VENTILATION
Blodgett BCT/BLCT ovens are equipped with an open/di­rect exhaust system that removes surplus humidity from the oven chamber. The exhaust system has an electrically operated damper.
The ventilation motor can be controlled directly from the oven. This means that the ventilation starts when a pro­gram is started and runs for 10 minutes after the program is completed.
BCT/BLCT-61, 62, 101, 102 and 202 ovens only. The ex­haust tube can be connected to a ventilation system. In that case, a special extraction funnel is tted to avoid suc­tion directly from the oven chamber. This extraction funnel can be ordered from Blodgett.
If an extraction hood is installed in the ceiling above the oven, it should project 20” (50 cm) over the front of the oven.

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 sufcient 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 BLCT-61G 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
BLCT-61G 40,900 BTU
New Total 270,900 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 40’ (12.2 m) 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 375,00 BTU. Since
the total required gas pressure, 270,900 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
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 sufcient 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 oper-
ate with the type of gas specied on the rating plate.
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.

Installation
Gas Hose Restraint
If the appliance is mounted on casters, a commercial ex­ible connector with a minimum of 3/4” (1.9 cm) inside di-
ameter 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 exible con­nector. The restraint should be fastened to the base frame
of the oven as close to the exible 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 Quick-Disconnect 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.
