Hi Felipe,
With rectifiers, connect between heater-winding and heater in either way (there is no polarity).
If the rectifier is directly-heated (5U4, 5R4GY etc) the rectifier filament-winding (transformer secondary) must not be shared with other heaters. And this winding must have strong insulation from other secondary windings on the same transformer.

Hello Felipe
Please have a look at the following Link to the Radiomuseum, because of the AZ1 is not only direct heated, but needs also the old filament-voltage of 4V.
