What appliance requires a leak test and CO test before use?

Explanation:
Gas-fired appliances need two safety checks before first use: a leak test to ensure there are no gas leaks in the connections, and a carbon monoxide (CO) test to confirm safe combustion and proper venting. The oven uses gas to generate heat, so both checks are essential to prevent dangerous gas leaks and CO buildup. Other listed appliances are electric or don’t involve burning fuel, so CO testing isn’t part of their typical startup checks. Therefore, the oven is the one that requires both a leak test and a CO test before use.
