Vaillant Ecomax 828e Combi Boiler

The heat exchanger insulation kit 210734 in the above comes with two door insulations. One is a perfect fit on the above boiler but the other not so perfect. Can the second one be used? Why does the kit supply two of them?

Thanks

Hi Roger,

Although I am not 100% certain on this it could be that you have an insulation kit for both the primary and secondary heat exchangers.  Hence why you have two insulation packages.
