The flue diameter is the same at 110mm, so if you are replacing a G11E you can use the existing flue.
The EUP11 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 G11E and MP11. This can be found in the related items section below.
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 G11E with an EUP11 more straightforward. This can also be found in the downloads section below.
