Internal wall box lintel

[sjj]

I wish to remove a wall between the kitchen and dining-room. This wall is

3.6m wide and 2.6m high, is a single brick thick, has a door to one side and supports a single story wall above. I want to make an opening about 3.3m wide and 2.3m high. There is only about 100mm of wall at the side of the door. How can I calculate the minimum end bearing length for an Expamet box lintel?
