I have a very very old furnace that was probably intended in its first years of life to work with coal. (That's what the previous owner told me) It was later on converted to gas. I noticed that there is cracks appearing on the sides of the furnace and I can see the fire inside burning!! I was wondering if anyone knew of to repair those? Is there any type of cement that I could use to fill in those cracks?
