The timer has a brown and black going. that's ok. but coming out is a red, an orange, a brown and a white. not sure which to join up.

should be able to have on manual as for normal cooking

You have an hob with European three phase at 220volt mains wire connected.
You need to to disconnect from mains connection box on hob and fit conventional British brown, blue and green/yellow.
Inside the connection box you will see three live terminals,(L1,L2 & L3) there are usually some brass links to join them all up and then attach brown core to one of them. If the links are not there then you will need to fit 2.5mm links from a piece of wire.

yes,the black and red era the 2 wires that supply 120 volts each for the required 240 volts necessary to operate the oven,the white is the neutral wire and the green is the case ground wire,and it should be connected to any metallic part on the oven not with the white wire,only if the power supplying this oven comes directly from the main power panel in the house and isn't off a sub panel before the oven can this be considered ok to be connected together

The US National Electrical Code only mandates white (or grey) for the neutral power conductor and bare copper, green, or green with yellow stripes for the protective ground. Power will generally be black or red. 3 phase power will have three colored lines, the first is generally black or brown, the second red or orange, and the third blue or yellow..
i,e,
Yellow/Green is Earth so 'E'. Brown is live so 'L', and Blue is neutral so 'N'.

Unfortunately you can't. Your wall outlet is a 110V circuit (B-110V; W- common) and your oven needs 220V circuit to operate. Red - 110V; Black - 110V; White - Common.

You will need to installed a 220V, 30 AMP (10-3/w ground) homerun from your circuit breaker panel to the oven

I think I worked it out. Black = Neutral. Brown = Live for the two power spades. The four spades for the timer (from the top+ = Red, Orange, Brown then white on the bottom. You will notice that Red and Orange, Brown and White are clipped together. Timer (and oven) is now working perfectly.

I can only speak for the 720. If you want a circuit/wiring diagram for this one, then I need an email address. I will then register this on my BT Digital Vault and you can the download the whole manual.
Looking at the diagrams, the neon for the main oven has white and black wires.
The white wire from the main oven neon goes onto the same connector on the thermostat block as the white wire to the oven element. The black wire from the neon goes to a common terminal on the top oven neon, which then goes onto P6 of the top oven switch (still black wire).
If you need any more info, then let me know.

According to the manufacturer's schematic, the orange wire is powered through a 15 amp breaker from the red conductor.

go ahead and wire the blk to blk and the red to the white as long as the data plat on the old oven say's 220 you should be ok

oven wiring has the same conventions as house wiring.
green = earth, outside coating
brown or white = one of core ends
black = the other end
