VZ 2/10 HDC 400 Combi Boiler Ignition Transformer (Baymak - Baxi Compatible)

Ensuring that gas ignites safely in your combi boiler's combustion chamber, the VZ 2/10 HDC 400 Ignition Transformer (Coil) is fully compatible with Baymak and Baxi appliances. By producing the high-voltage spark the appliance needs at start-up, it allows the system to heat safely and without interruption. With its original socket design and part code JJJ008511790, it is a direct replacement for your faulty transformer.

Safe and Uninterrupted Ignition Performance

Ignition problems are among the most common combi boiler faults and prevent the appliance from starting. This transformer instantly converts the 220-240V mains input voltage into high ignition energy and delivers it to the electrodes. Thanks to its wide operating temperature tolerance from -20°C to +100°C, it ensures stable operation of your combi boiler even in the harshest conditions and under high heat. Its compact design makes installation extremely practical.

Practical Usage Note for Field Technicians

Technician's Note: When replacing the ignition transformer, always cut the combi boiler's power at the fuse. After fitting the new transformer, make sure the sockets are fully seated and the ignition electrode cables are not loose. Also inspect the electrode tips when replacing the transformer; if there is soot, oxidation or scale on the electrodes, lightly sanding them clean will improve the new transformer's performance and prevent complaints of explosive (noisy) ignition.
