Introduction

Description of the Blodgett 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 prod­uct, cooked at a lower temperature in a shorter
amount of time.

Blodgett Combi ovens are quality produced using
high-grade stainless steel with first class work­manship.

The two speed fan, which is guarded against acci­dental finger contact, is driven by a quiet and pow­erful motor.

The use of high quality insulation impedes exces­sive heat radiation and saves energy.

The oven has optional adjustable legs which
adapt easily to slightly uneven surfaces and op­tional floor stands which are designed for use with
all of the table models.

Oven Location and Ventilation

OVEN LOCATION

The well planned and proper placement of your
oven will result in long term operator convenience
and satisfactory performance.

Certain minimum clearances must be maintained
between the oven and any combustible or non­combustible construction. See the table below.

In addition, the following clearances are recom­mended for servicing.

D

Oven body sides --- 12” (30cm)

D

Oven body back --- 12” (30cm)

NOTE: On gas models, routine servicing can usu-

ally be accomplished within the limited
movement provided by the gas hose re­straint. If the oven needs to be moved fur­ther from the wall, the gas must first be
turned off and disconnected from the oven
before removing the restraint. Reconnect
the restraint after the oven has been re­turned to its normal position.

Left Side Heat Shield

Heat sources should not be near the air vents lo­cated on the left hand side of the gas appliance.
Consult the factory for optional protective side
heat shield.

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 w ith 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 appropriately 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.

U.S. and Canadian Installations

Refer to your local ventilation codes. In the ab­sence of local codes, refer to the National ventila­tion code titled, “Standard for the Installation of

Equipment for the Removal of Smoke and Grease
Laden Vapors from Commercial Cooking Equip­ment”, NFPA-96- Latest Edition.

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 installationand/or
operation of your unit, please contact your local
distributor. If you do not have a local distributor,
please call Blodgett Combi at 0011-802-860-3700.

OVEN LEVELING
This oven should be set up in place.

With any stand or oven, be certain that the surface
is level, even and solid. A sloped or uneven base
may cause the appliance to function improperly.
Minor unevenness can be corrected by adjusting
the metal leg feet. The maximum adjustment of the
leg feet is 1-3/8” (35mm).

WATER CONNECTION -- CNV14E ONLY

NOTE: Hot water maximizes steam production but

is not required. Cold water may be supplied
to both inlets if hot water is not available.

Connect the appliance to quality water via a pres­sure hose with 3/4” (19mm) couplings. See
Figure 6 for connections. A shut off valve is to be
provided adjacent to the oven.

WARNING!!
Operating the appliance without the water

regulator installed will invalidate your war­ranty.

Water must meet the following minimum require­ments:

D

Total Dissolved Solids (TDS) content will not ex­ceed 30 parts per million.

D

WARNING!!
The use of poor quality water will invali-

date your warranty.

DRAIN CONNECTION

The steam vent assemblies are constructed of 2”
DWV copper piping reduced to 1-1/2 DWV pipe. If
the vent system is not purchased as an option
(R9381), Blodgett Combi recommends plumbing
the oven as shown in Figure 7.

The steam vent should be run to an open floor
drain avoiding flexible hose that could sag and al­low trapped water to accumulate. The customer
must supply the piping from the oven to the drain.

Connect the drip pan drain to the steam vent with

1.125 I.D. hose.

Use the drain vent assembly and a 2” ( 50.8mm)
pipe for drain 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.

The circuit break er that is used to provide power
to this a ppliance must have a minimum of .076”
(3mm) contact spacing. The circuit breaker must
meet all Local and National installation standards.

All appliances must be installed in accordance
with Local or National Electrical codes.

A wiring schematic is located on the inside of the
removeable side panel.

NOTE: Disconnect the power supply to the ap-

pliancebeforeservicing.

WARNING!!
Improper installation will invalidate your

Electric Models

A strain relief for the power supply cord is required.
The installer must supply a cord bushing that meets
all Local and National installation standards.

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 CNV14G 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
CNV14G 65,000 BTU
New Total 295,000 BTU

3. Measure the distance from the gas meter to
the cook line. This is the pipe length. Let’s say
thepipelengthis30’(9m)andthepipesize
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 375,000
BTU. Since the total required gas pressure,
295,000 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. For example: a schedule 40 1-1/2” ell
fitting has an equivalent capacity of 4.2”
(10.2 cm) of straight pipe. 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 a ppliance while the burners are on. A suf ­ficientgaspressuremustbepresentattheinletto
satisfy these conditions. Refer to the t able 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 attached to the right side of the ap­pliance.

Each oven is supplied with a regulator to maintain
thepropergaspressure.The regulator is essen-

tial 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
pressuresinexcessof1/2psig(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.
