I am upgrading my woodstove to a vermont castings  dutchwest 2462, it is annual 8" exhaust,  however the fireback is preventing the upgrade, i have read that a fireback in not needed for wood stove use, is this true? I am more than willing to remove it and my chimney will accept 8" without a problem,  I don't want to damage my house or burn it down.
