I'll have a try.
Kiwichap wondered, why the chimney of Krema I isn't connected to the building. The chimney isn't the original war-time chimney, but was "reconstructed" by the Poles after the war, exactly as the "gas chamber" and the crematorium ovens were as well. As far as I know, the Poles and the Jews claimed until the end of the 1970ies or the beginning of the 1980ies, everything was "original", but when Prof. Faurisson dug out the various plans and diagrams mentioned in this thread, they had to admit that they had "reconstructed" the crematorium, allegedly exactly as it had been during the "Holocaust". Prof. Faurisson, Germar Rudolf, Carlo Mattogno and others proved that this is not true.
There were allegedly (and according to the plans and documents) three double-muffle ovens in the building, the first one was built in summer 1940, the second one in February 1941 and the third one (in the plans on the left side) in summer 1942.
The crematorium was put out of service on 19 July 1943, when the two new crematoria in Birkenau were completed.
In fall 1944 the former crematorium was converted into an air-raid shelter for the SS-hospital, which was situated across the road (visible at the background of the photograph posted above). Therefore the chimney was dismantled (perhaps this had been done already earlier on), a new entrance leading to an air-lock (on the right side at the bottom on the plans I named in my last post - this entrance today is presented to the visitors as "entrance of the victims to the gas chamber") has been built and the mortuary (the alleged "gas chamber") was divided by partiton walls into four rooms. The plan for the conversion into an air-raid shelter is to be seen at: http://vho.org/D/vuez/v2.html in Abbildung 2.4.
When the Poles "reconstructed" the building after WW II, they made a quite embarrasing mistake: By removing the partition walls, which divided the former mortuary in four rooms, they went "one wall too far", i.e. they removed also the wall to the washing room (No. 4 at: http://www.vho.org/D/gzz/RudolfKIHEUTE.gif and according to this "new [too large] gas chamber" they placed the "Zyklon B - holes" on the roof (No. 2 in the plan at above named URL), so that they are placed in a proper way for the too large room, which never existed in the "German time" of the building, but in the wrong way for the former mortuary, which they want us make to believe was used as a homicidal "gas chamber".
The ovens also had been removed by the Germans and the Poles rebuilt them in a rather flimsy manner, so that they could not be operated today. Since the (mock-up) chimney is not connected to the building, there were some suspicions that it never could have been at that place, but we are told that there were underground smoke canals leading to the chimney, for the ovens were equipped with 3 hp three-phase AC motor powered exhaust fans. Moreover, there are two vents for the supply of fresh air to the furnace room on the roof.
Ultimately, there was some confusion, when trying to connect the different plans to the photograph of the building. This was due to the fact that the photograph was taken from the opposite direction. So, if you rotate the plans by 180 ° so that the chimney is on the bottom (instead of the top) of the plan, you have the same view as on the photograph.
