Aqua-Hot spewed excessive white smoke

Aqua-Hot spewed excessive white smoke
My coach had been sitting for several weeks when I fired up the
aqua-hot and a cloud of white smoke started spewing from the exhaust.
It was so much that neighboring campers banged on my door to see if
the coach was on fire and we needed to evacuate.I had experienced
white smoke emissions before, but it cleared up within the first
cycle. This time, after cycling several times, the smoke finally
cleared and it ran without any smoke emitting from the exhaust.

Opinions- water in the fuel? need new filter? need to drain fuel
filter periodically? all of the above? I did not investigate, but is
the fuel filter drainable? Also, is it difficult to replace?

Thanks for your help in advance!

Hi Wayne,

Before doing anything else, perform the annual service which
consists of a nozzle and filter change, burner cleaning and
inspection. There are detailed instructions in your manual or
in .pdf format on Vehicle Systems website. This should be done each
year. Also check that the air intake did not get moved or blocked.
You should see a red paint dot where the factort set it. (This is
under the burner assembly.) Inspect the photo eye for cracks or
carbon buildup and replace if necessary. Also be sure the ignition
points are adjusted properly, there is a guage screwed to the
outsine of the burner. Before reinserting the re-assembled burner be
sure the photo disk assembly floats freely in its mount. All of this
is explained in the service manual which has good photos too. Sounds
like more of a job than it is. If that does not cure the smoke
problem, you'll have to take it to an AquaHot or Webasto shop. BTW,
many large boatyards do AquaHot service. Also check for fuel leaks
when you disassemble the unit. There was a recall on leaking
fuelpumps.
