The HESTAN 28057 is a gas assembly designed for 24-inch griddle units in professional-grade cooking equipment. This assembly supplies the burner system with the gas delivery components required for consistent heat output across the griddle surface. It is a direct service replacement part intended for use by qualified appliance service technicians or licensed gas fitters performing maintenance or repair on Hestan griddle equipment.
This gas assembly is suited for commercial-style residential griddle installations where the original gas delivery components have failed or require replacement. The part is identified as a service-level component, indicating it is intended for field replacement during scheduled maintenance or breakdown repair rather than initial installation. Technicians servicing high-output residential cooking equipment will recognize this assembly as a core functional component of the burner circuit.
Compatible with the following Hestan service models as stated by the manufacturer: KRD484GD-SERVICE, KRG484GD-SERVICE, and KRT484GD-SERVICE.
Installation must be performed by a licensed gas fitter or qualified appliance service technician in accordance with local gas codes and the appliance manufacturer's service documentation. Shut off the gas supply at the shutoff valve and allow the unit to cool completely before beginning any disassembly. Verify all gas connections for leaks using an approved leak detection solution after reassembly and before returning the unit to service. Do not attempt to modify or adapt this assembly for use outside its listed compatible models.
