Steam cannon not working.

What i mean by this, is that when i put a fire source by a water cannon, no matter how long i wait it won't heat up, iv'e tried many different placements but it's the same thing each time, this bug has been with me since water cannons first came out so iv'e never actually made a steam cannon
