Those Hoover dryers and most australian dryers vent out of the grill at the front. If you look in the center there is a latch that you use to pull off the front, behind that is the lint filter. To start the dryer you select your time on the dial and then press the door latch and the dryer starts, These models were non reversing. The wall mount style is typical of australian laundries due to lack of space in our laundry rooms and it is certainly a back strain saving way of moving your clothes from the washer to the dryer. Most australians however take advantage of the all year round warm weather and peg their laundry outside and only use their dryers a few times a year.
In terms of wattage/amp, i have no idea, you just plug it straight into a normal power socket and your ready to go.
I find it very cool how when you purchase the dryer you are asked weather you need the controls orientated so that you can read them while mounted on the wall. I remember that particular dryer was once on the floor and the controls were upside down!.
As far as i know its a good dryer and i have used other peoples and they hold a decent amount of laundry and ae able to dry most full loads in an hour.
