There were four elliptical-shaped funnels; the three forward ones took the waste gases from the boiler furnaces, and the after one was placed over the turbine hatch and was used as a ventilator. The galley funnels were led up this funnel. The uptakes by which the waste gases were conveyed to the funnels were united immediately above the watertight bulkhead which separated the boiler rooms.
All overhead discharge from the circulating pumps, ballast pumps, bilge pumps, etc., were below the deep load line, but above the light line.
The boilers were supported in built steel cradles, and were stayed to the ship's side and to each other athwart ships by strong steel stays. Built steel chocks were also fitted to prevent movement fore and aft.
Silent blow-offs from the main steam pipes were connected direct to both condensers.
