What is claimed is: 1. An exhaust flue supporting apparatus comprising: a mounting plate, a flange plate and a centering plate; the plates integrally-joined by break-off tabs as a single planar metal sheet; the mounting plate having a first rectangular flue access hole and a first pair of opposing integral flanges, the first flanges movable into right angle positions relative to the planar metal sheet; the flange plate having a second rectangular flue access hole and a second pair of opposing integral flanges, the second flanges movable into right angle positions relative to the planar metal sheet; the second pair of flanges configured and sized to enter the first flue access hole when the flange plate is separated from the planar metal sheet and positioned with the first and second access holes in coincidence; the centering plate having a third flue access hole and a strapping-tab, the strapping-tab movable into a right angle position relative to the planar metal sheet; the mounting plate, flange plate and securing plate configured and sized for mutual abutment about an exhaust flue positioned within the first, second and third flue access holes, when the plates are separated at the break-off tabs and the first and second pair of flanges and the strapping-tab are moved to right angle positions relative to the planar metal sheet. 2. The exhaust flue supporting apparatus of claim 1 further comprising a planar securing strap joined by the break-off tabs to the planar sheet, the securing strap sized and configured for encircling the exhaust flue and the strapping-tab. 3. The supporting apparatus of claim 1 further comprising a planar securing strap joined by the break-off tabs to the planar sheet, the securing strap encircling the exhaust flue and the strapping-tab. 4. A supporting apparatus comprising: an exhaust flue and a mounting plate, a flange plate and a centering plate; the plates integrally-joined by break-off tabs as a single planar metal sheet; the mounting plate having a first rectangular flue access hole and a first pair of opposing integral flanges, the first flanges movable into right angle positions relative to the planar metal sheet; the flange plate having a second rectangular flue access hole and a second pair of opposing integral flanges, the second flanges movable into right angle positions relative to the planar metal sheet; the second pair of flanges configured and sized to enter the first flue access hole when the flange plate is separated from the planar metal sheet and positioned with the first and second access holes in coincidence; the centering plate having a third flue access hole and a strapping-tab, the strapping-tab movable into a right angle position relative to the planar metal sheet; the mounting plate, flange plate and securing plate separated from the planar metal sheet and positioned in mutual abutment about the exhaust flue with the exhaust flue positioned within the first, second and third flue access holes.
