Service order

JM_2 Member Posts: 108
an old 3 family house. One of the gas/steam boilers
(American Standard G26 counterflow sys) needed some work. When I looked at the service order I noticed one item " Re-sealed back of boiler behind scorch mark". The Boiler did have a faulty relief valve so it never shut off on pressure. But what is Re-seal? Also the flame lookas alot taller than the other boilers.
