Viessmann Vitogas 100

Spartanator Member Posts: 3
Hey everyone,

Wanted to double check with some of the older members.

We've had to tear apart a Vitogas 100 boiler due to combustion issues, and gas safety came along and stated that he wanted the cast sections re-gasketed between the fire sides of the sections.

Can anyone please point me in the right direction for gasket/sealant material that would roughly be the same as OEM?

For some reason, our suppliers/distributors have no clue, and aren't very much help.

Cheers!, and Thanks in advance!

    You want to split the sections? I’m not sure I understand. If yes, why? No normal/ typical heating guy would split apart a boiler and reassemble.
