3. ELECTRICAL GROUNDING
INSTRUCTIONS
This appliance must be grounded. This oven is equipped
with a cord having a grounding wire with a ground-ing
plug. It must be plugged into a wall receptacle that is
properly installed and grounded in accordance with the
National Electrical Code and local codes and ordinanc-
es. In the event of an electrical short circuit, ground-ing
reduces risk of electric shock by providing an escape
wire for the electric current.
WARNING - Improper use of the grounding plug can
result in a risk of electric shock.
The oven is equipped with a 3-prong grounding plug.
DO NOT UNDER ANY CIRCUMSTANCES CUT OR
REMOVE THE GROUNDING PIN FROM THE PLUG.
The Power Supply Cord and plug must be connected to
a separate 120 Volt AC, 60 Hz, 15 Amp, or more branch
circuit, single grounded receptacle. The receptacle
should be located inside the cabinet directly above the
Microwave Oven/Hood mounting location.
Note:
1. If you have any questions about the grounding or
electrical instructions, consult a qualified electrician
or serviceperson.
2. Neither SMEG nor the dealer can accept any liability
for damage to the oven or personal injury resulting
from failure to observe the correct electrical connection
procedures.

4. HOOD EXHAUST DUCT
When the hood is vented to the outside, a hood exhaust
duct is required. All ductwork must be metal; absolutely
do not use plastic duct. Check that all connections are
made securely. Please read the following carefully:
EXHAUST CONNECTION: The hood exhaust has been
designed to connect to a standard 31/4" x 10" rectangular
duct. If round duct is required, a rectangular-to-round
adapter must be used.
REAR EXHAUST: If a rear or horizontal exhaust is to
be used, care should be taken to align the exhaust with
the space between the studs, or wall should be prepared
at the time it is constructed by leaving enough space
between wall studs to accommodate exhaust.
MAXIMUM DUCT LENGTH: For satisfactory air move-
ment, the total duct length of 31/4" x 10" rectangular or
6" diameter round duct should not exceed 140 feet.
Elbows, adapters, wall, roof caps, etc. present addi-tional
resistance to air flow and are equivalent to a section of
straight duct which is longer than their actual physical
size. When calculating the total length, add the equivalent
lengths of all transitions and adapters plus the length of
all straight duct sections. Figure 4 shows the approximate
feet of equivalent length of some typical ductwork parts.
Use the values in parentheses for calculating air flow re-
sistance equivalent, which should total less than 140 feet.
