The flue diameter is the same at 90mm, so if you are replacing a D61 you can use the existing flue.
The EUP6 has a piezo ignition and is not available with an electronic ignition.
The EUPFK fitting/conversion kit will be required in order to fit the water heater as the gas and water connections are different to those on the D61 and MP6. This can be found in the related items section below. If you require a 10mm fitting kit, please order the EUPFK10 instead.
There is a conversion document available on the troubleshooting section of this website and within the fitting/conversion kit to make the replacement of a D61 with an EUP6 more straightforward. This can also be found in the downloads section below.
