From the range installation guide:
A flexible-metal appliance connector used to connect the range to the gas supply line should have an I.D. of 0.5 in (1.3 cm) and be 5 ft (152 cm) in length for ease of installation.
Samsung recommends having the range installed by a qualified technician. For more information on installation, please contact your local Best Buy appliance or installation team.
Thank you,
Ms. Samsung
