Installation 
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
Proofing - 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
The Blodgett Combi-Oven/Steamer
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 equipment replacement
•a wider range of menu choices
•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 pre-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 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 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.

Description of the Combi-Oven/Steamer
ABOUT THE OVEN/STEAMER
Blodgett Combis are quality produced using high-grade stainless steel with first class workmanship.
The multiple 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.
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-
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 to use control. With graphical symbols and storage for 50 product recipes the BCT/BLCT is easy for even inexperienced kitchen staff to operate.
Cleaning is kept to a minimum thanks to the automatic Combi Wash system.

WATER CONNECTION
Blodgett BCT/BLCT ovens have two water connections. Both are located at the back of the unit.
BCT/BLCT-61, 62, 101, 102 and 202 models
•1 connection for raw water for the condensation jet.
•1 connection for steam generation and the Combi Wash jet in the oven chamber. Must meet the requirements applying to water supplied to household appliances.
Quench Steam
Figure 3
BLCT-23, 6 and 10 Mini Combi models
•1 water connection. Must meet the requirements applying to water supplied to household appliances.
To facilitate cleaning and servicing, the oven should be connected with an approved flexible 3/4” hose. Permanent installations should be fitted with a stop-tap and a non-return valve.
Before connecting the oven to water, flush 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.

Electrical Connection and Ventilation
ELECTRICAL CONNECTION
NOTE: Electrical connections must be performed by a qualified installer only.
Before making any electrical connections to these appliances, 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 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 appliance’s ground fault interrupter (GFCI). Some GFCIs are more sensitive than others. Blodgett has qualified the
Pass and Seymour 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. Blodgett recommends using this specific 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 fitted 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.

Installation 
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 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 fittings will decrease pipe capacities. Contact your local gas supplier if you have any questions.

Installation
Gas Connection
PRESSURE REGULATION AND TESTING
The gas pressure to the appliance must be rated for each appliance while the burners are on. A sufficient 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 specified 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 filings, shavings, pipe dope, and other debris. After connection, the appliance must be checked for correct gas pressure.
U.S. and Canadian Installations
Installation must conform with local codes, or in the absence of local codes, with the National Fuel Gas Code, NFPA54/ANSI Z223.1-Latest Edition, the Natural Gas Installation Code CAN/CGA-B149.1 or the Propane Installation Code, CAN/CGA-B149.2 as applicable.
General Export Installations
Installation must conform with Local and National installation standards. Local installation codes and/or requirements may vary. If you have any questions regarding the proper installation and/or operation of your appliance, please contact your local distributor. If you do not have a local distributor, please call Blodgett Combi at 0011-802- 658-6600.

Installation 
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.
Gas Hose Restraint
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.
General export installations
Installation must conform with Local and National installation standards. Local installation codes and/or requirements may vary.
