De Dietrich 100009893 البروبان HG44 طقم تحويل غلاية MCR

This converting kit adapts a De Dietrich boiler of the HG44 MCR designation to burn propane instead of natural gas. Parts of this type replace or supplement the original gas train components – injectors, gas valve springs or orifices, and possibly the gas valve itself – to match the different calorific value and supply pressure of propane. The kit sits between the gas supply line and the burner, altering the fuel-air mixture ratio so that the flame stays stable and complete combustion is achieved. It works with the burner control, gas valve, and the burner’s mixing assembly. Selection for such a kit is strictly by boiler model and the intended fuel (propane). No technical rating is needed because the orifice diameters and pressure adjustments are preset for the specific appliance. When replacing an existing converting kit or converting a boiler for the first time, confirm that the kit includes all necessary hardware: injectors, gaskets, and any labelling for gas type. Also verify the propane supply pressure at the site; a mismatch can cause poor ignition or sooting. Always follow the boiler manufacturer’s instructions for converting the burner control’s gas type setting if it is adjustable.
