I have an Energy Kinetics System 200 furnace which is 1 1/2 years old. It sits in the basement below a fireplace hearth on the floor above it. I had been cutting and chiseling brick and mortar on the fireplace hearth and some of the dust and small pieces fell into the basement through a small joint (1/8") . Some of this landed on the top of the furnace. I vacuumned the top of the furnace. Next day I found a small puddle of water beside the furnace but could not tell where it came from....no wet pipe joints. There have not been any more puddles in almost a week now. I may have lightly touched some of the pipes or relief valve but nothing was jolted. I contacted Energy Kinetics and the response was there should not be any water. I've been keeping watch on the furnace. Call a tech or wait and see?
