I have a Combi -Baxi instant 105e which has a faulty plate heat exchanger. The plate exchanger is located in the back of the unit. The repair procedure states to support the unit, remove the 2 screws, lift unit up and to the left taking care not to damage any wires or connections. My question is: Can this unit be taken out through the front or does it have to come out from the side. If from the side, how do I remove a section of the outer case to allow for this?

I am pretty sure that it can be taken out from the front.
However, I think that other parts have to be removed first.
Unfortunately I just look at them and do whatever is necessary.
Perhaps someone can advise on exactly what has to be dismantled.

ONLY do this if you are a competent gas engineer as removal of the gas valve is neccesary 
Then it comes out through the front !

LOL yes thats the Stored water in the expansion vessel
the best way to drain them is to remove the nut off the end of the left hand blanking nut on the isolation valve remove the motor head off the diverter and push the little pin half way down with a stubby! then crack the nut on the back of the 3 way valve where it goes upto the Exp vessel sorted

Remove the diverter motor then it will come out the front if you twist it around so its laying flat with the holes facing up then pull it out over the top of the diverter valve. Just needs a little wiggling round.
