I am amazed at how easy it is to use my Dauntless with the combustor installed. I just don't understand why HHT (aka Forge and Flame) still market VC wood stoves as "Flexburn". Granted it took me a season to figure out this stove. Now in hindsight my dealer should have never let me walk away without buying the performance package. It should be included! Why it's not just flabbergasts me!
