Installation
electrical Connection and ventilation
eLeCTRiCAL ConneCTion
NOTE: Electrical connections must be performed by a
qualified 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 locat-
ed 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 war-
ranty.

A strain relief for the power supply cord is provided. The
installer must supply a cord that meets all Local and Na-
tional installation standards.
Gas Models
U.s. and Canadian installations
A power cord (115V units only) is supplied with a plug at-
tached. Plug the power cord into the desired receptacle.
NOTE: The BLCM-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 cur-
rent toward Earth Ground. Especially, at the moment of
switching ON this can cause an inadvertent trip of the ap-
pliance’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 re-
placed by a special cord or assembly available
from the manufacturer or its service agent.
venTiLATion
Blodgett BCM/BLCM 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 pro-
gram is started and runs for 10 minutes after the program
is completed.
The exhaust tube can be connected to a ventilation sys-
tem. In that case, a special extraction funnel is fitted to
avoid suction directly from the oven chamber. This extrac-
tion 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.
