Wondering if anyone can hazard an educated guess. i bought a b-vent 2600 Radiance gas stove in the mid-'90's. after we delivered it to the house, we had our plumber install the propane kit (comes as natural). i believe i have the full kit plus multi-page conversion instructions. i've often seen inquiries searching for a conversion kit for these stoves, and seem to recall that they are no longer available, kind of bricking those stoves unless one wants to add a bottle of propane.
