As a former commercial
fisherman... We used to have 3 grades of diesel
. People that ran their stove long hours at low settings usually bought #1 diesel
for the stove and #2 for the engine
. #1 was supposed to be equal to heating oil
and produced less soot. #3 was bought by caterpillar owners. The diesel sold in the US now is formulated to meet some government
standard and not to burn cleanly in a stove. Burning kerosene will help the soot. Also, if you run the stove at a hot setting at some time every day it helps the soot problem. Red Devil helps. Follow the directions for installation
on pipe lengths and bends, too. Most people that have trouble ignore the directions. Also when cold, don't heat too fast. You can crack the cast iron top by running full heat on a cold stove.
When I fished almost all boats had diesel stoves. The Seattle fish dock
used to have a sign forbidding unattended diesel stove operation. I always considered Dickinson
to be top of the line.
