I just finished servicing my Aqua Hot today. I followed the instructions in the FMCA magazine, replaced the nozzle, cleaned the burner chamber and replaced the filter. We actually use the diesel burner very little, and this is the first service since we purchased the Beaver in 2007. The combustion chamber had very little soot in it, but after replacing everthing, I noticed that it burns cleaner, with less odor. Very simple process, took about an hour with help from a four-year old granddaughter. Probably would have taken about 30 minutes without help.
