The barrel stove is a primitive stove that has never been designed as a home heating appliance for everyday use in living spaces. It is designed for use in open air situations and workshops. It has not been safety tested for indoor use in relation to UL and CPSC safety standards thus we cannot recommend that it is used in a living space.
This particular kit has been in production for many years and cannot possibly fit every barrel each consumer may use. I apologize that it did not fit your intended use situation. If you are truly unsatisfied with the product please contact Home Depot customer care for a return authorization or you may contact our customer care center for a complete kit replacement.
From the looks of your photo you are using two barrels. You should also purchase the BKAD500 to obtain the legs that are designed to go between the two barrels. The BSK1000 that you are reviewing is only designed for a single stove.
