It is recommended that the electrical power supply to
each unit heater be provided by a separate, fused, and
permanently live electrical circuit. A disconnect switch of
suitable electrical rating should be located as close to the
gas valve and controls as possible. Each unit heater must be
electrically grounded in accordance with the latest edition of
the United States National Electrical Code, ANSI/NFPA No.
