Many markets sit on a fuel boundary — some regions use LPG cylinders, others are connected to piped natural gas. A CKD assembly operation that can serve both fuels with one line doubles its addressable market. The key is planning the nozzle strategy and the testing process up front. Here is how.
LPG and natural gas burn identically well once the correct nozzle is fitted — but the apertures differ: LPG uses smaller apertures at higher pressure, natural gas uses larger apertures at lower pressure. The rest of the stove is largely fuel-neutral. So a dual-fuel line is really a dual-nozzle line.
Organize assembly so the nozzle is the single fuel-specific component. Keep LPG and natural gas nozzles clearly separated and color-coded, and fit the correct nozzle set at a dedicated station. THREEMI supplies nozzles in 16 aperture sizes from 0.45mm to 1.35mm on a unified M6x0.75 thread, covering both fuel types in one parts system.
Every assembled stove must be leak-tested and flame-tested for its specific fuel. Label each finished unit clearly — LPG or natural gas — and calibrate your test rigs to the correct supply pressure. A stove shipped with the wrong fuel label is a serious safety risk.
With the nozzle station and fuel-specific testing in place, one CKD line can serve both fuel markets at minimal extra cost. THREEMI supplies complete CKD kits plus assembly guidance and equipment advice, helping you build a dual-fuel operation that captures demand on both sides of the fuel line.
