Many people do not realize that gasoline in garages can ignite when a boiler or water heater comes on. Modern codes dictate that when a boiler is located (or relocated) in the garage that it must be at least 18 inches above the floor.

When any fuel burning equipment is located in a garage, even though it may be behind a wall, it is still in the garage. You may not keep your car there, but if a gasoline leak were to occur, it could cause an explosion. Even gas cans from lawnmowers and other equipment can be knocked over, and if your boiler turns on at that time - KABOOM!

Houses have been leveled, and people have been killed by this.

Keep this in mind if you have a garage, and make sure to follow modern building codes and standards when relocating your fuel burning boiler or water heater to the garage. - Ray
