Improper
grounding
will
cause
malfunc
tion
(such
as
continuous
sparking
of
the
burner
igniters),
may
damage
this
appliance,
and
could
create
a
condition
of
shock
hazard
at
the
igniter
of
each
burner.
If
the
circuit
does
not
have a
grounding
type
receptacle,
it
is
the
responsibility
and
obligation
of
the
installer
or
user
to
have
the
existing
receptacle
changed
to
a
properly
grounded
receptacle
in
accordance
with
all
applicable
local
codes
and
ordinances
by
a
qualified
electrician.
In
the
absence
of
local
codes
and
ordinances,
the
receptacle
replacement
shall
be
in
accordance
with
the
National
