Hi Pat,
Thank you for reaching out, and we hope you are in good health. We appreciate your interest in Samsung home appliances, specifically with Samsung - 6.3 cu. ft. Flex Duo™ Front Control Slide-in Electric Range with Smart Dial, Air Fry & Wi-Fi, Fingerprint Resistant - Stainless steel.
The range has no specific venting (down/updraft). The oven vent is
located above the right rear surface unit. This area could
become hot during oven use. Never block this vent or place
plastic or heat-sensitive items on it.
I have shared the user manual link below. Please access the link and turn to page 21 for the location of the oven vent.
