A kiln has a control box pivotably coupled to an oven portion via a hinge at a lower end of the control box so that the control box can pivot about the hinge from a closed position adjacent the oven portion to an open position where an upper end of the control box is separated from the oven portion. The apparatus includes a reaction chamber including a gas outlet, and an evacuation device. The device further includes a housing connected to the second end which is substantially perpendicular to the longitudinal member.
