boiler utilizes flue gas heating

What happens if a boiler flue is blocked? | Viessmann

It is a requirement that your boilers flue is completely sealed. If there are gaps around the edge of the flue there's a chance that some of the gas could re-enter the house. The flue needs to be sealed on both sides of the wall or roof where it exits the home. This is usually done using sand cement.
