There is good reason NOT to convert the smoke unit to liquid type, that being that from then on you HAVE to keep fluid in it or the unit will burn out. With the old heater unit it does not matter whether there is a pill or fluid in it at all. The old heater will take smoke fluid just fine and smokes even better if you overhaul it and add the pac man batting that some dealers sell now. All of mine have been using smoke fluids for many years and no problems.
