Personally, I would not try to convert the diesel stove to wood-burning. I don't think there is enough safety margin. I would either see about getting the diesel up and running to specs, or sell it and get a Navigator Halibut for cooking with wood or coal:
HALIBUT COOKSTOVE INFO & SPECS.
They are not particularly large and look very good from the ones I have seen when I visited the foundary where they are made.
