De Dietrich 7614735 propane HX54 conversion kit

This article is a propane (LPG) conversion kit for the HX54 model range, listed under the De Dietrich brand with manufacturer codes 7614735 and 336.508.008. Parts of this type are used to adapt a burner or boiler that is originally set for natural gas to operate on propane. The kit typically includes replacement injectors, a gas valve spring or conversion screw, and a setting label; in some cases it also supplies a different gas valve or a pressure regulator component. The conversion changes the fuel flow rate and air/fuel ratio so the appliance meets the combustion characteristics of propane. Such kits are selected exclusively for the specific appliance model and the target gas family. The correct kit must match the exact model designation (here HX54) and the burner type. During replacement the gas valve must be re‑set to the propane pressure range, and combustion must be verified with a flue gas analyser. The original gas valve rating plate and the burner data plate should be checked to confirm the kit is applicable. No generic conversion set can be used; only the kit intended for that appliance model ensures safe ignition and emission levels under the new fuel.
