Master Burner flange 4033.059

The Master Burner flange 4033.059 is a component used to mount the burner to the fuel system of compatible Master air heaters. It is made of heat-resistant metal and features reinforced fastening for vibration resistance. The flange has a connection diameter of 50 mm, operates at pressures up to 3 bar, and withstands temperatures from -20.0 to 150.0 °C. It ensures a hermetic seal to prevent fuel leakage and maintain stable system pressure.

Parts of this type are selected by matching the connection diameter and mounting hole pattern to the burner and heater body. Before ordering, measure the existing flange's diameter and verify the bolt spacing. The flange must be compatible with the specific model and year of the heater, as listed in the manufacturer's compatibility chart. Installation involves removing the old flange, cleaning the mating surfaces, and securing the new flange with the appropriate fasteners.

When flanges of this kind fail, common issues include fuel leaks at the connection point, which may be visible as wet spots or a fuel odor. Vibration can cause fasteners to loosen, leading to an unstable burner flame or intermittent operation. Overheating may warp the flange, causing misalignment and poor sealing. Check for cracks, deformation, or signs of fuel seepage around the flange.
