Spirit Boiler Corporationsâ âSpirit S4868Pâ outdoor furnace was bought out in 2006
by another company, re-named and sold as a cleaner burning, more versatile option
for their outdoor wood burning furnace buyers. That company has since dissolved.
And rather than start production of the S4868P furnace again, Don has decided to
make the S4868P outdoor furnace plans available for people who want to pursue their
own outdoor wood burning furnace project..
