After a stove passes its gas leak test, the next quality gate is burner flame testing — confirming that every burner lights and burns cleanly, with the correct flame shape and color. This step verifies that nozzles, flame spreaders, and caps were assembled correctly and sized for the gas type. Here is how to build flame testing into your CKD assembly line.
A dedicated burner flame tester is the core tool. It provides a controlled gas supply and a viewing area so an operator can observe the flame under standard conditions. For higher-volume lines, semi-automated testers record results and flag burners outside spec. Supplement the tester with a gas pressure gauge and an ignition tester to isolate root causes quickly.
Flame testing should be a mandatory step for every stove, not a spot check. A burner that lights poorly or burns yellow points to a wrong nozzle size or a misaligned part — issues that must be caught before the stove reaches a customer. THREEMI advises CKD partners on flame-testing equipment selection and setup, and we provide the assembly guidance so your burners are installed and verified correctly from the first unit.
