From what I have read on this site, deasil gives out a higher heat btu than kerosene on the Wallas. I presently use kerosene (no problems), if I switch to deasil, do you think I can just run down the kerosene to low and then top up with deasil, or do I need to flush the system clean before switching to deasil? If I need to flush, what is the procedure?
