I recently purchased an annual service/maintenance kit from AquaHot and serviced my AquaHot myself. First time. I was proud of myself because I got it working and all seemed to be fine. After a couple of days I started smelling diesel and found a small puddle under the AH. I disassembled, taking the burner out, and wiped everything down. While putting it back in, I over torqued the lower toggle nut and broke the aluminum blower casting. Bought a new casting as well as a new swirler and swirler housting as the old swirler was deformed. When I put it back together and fired it up, it smoked like crazy, black smoke from the exhaust pipe and white smoke from the AH compartment. When I shut it off, and after the burner fan stopped it dumped a bunch of diesel, maybe a 1/2 cup, out of the bottom of the burner unit. I took it out, disassembled and reassembled and installed, same problem. Now, even when off, it leaks diesel. Any suggestions on problem and how to repair?
