I would like to mount this on an internal wall which is immediately next to an external wall so the flue can go straight out the wall.
In fact if the boiler were supported by the short side not the longer side (i.e. the back) it would in fact be mounted on an external wall.
I suspect regs say it's got to be on an external wall? Why is this - how is it safer?
It's entirely dependent on the model of boiler and the flueing arrangements specified by the manufacturer.

Why would you suspect that? As long as the flue and fan specifications are suitable for the length of flue there shouldn't be a problem. Fitting one that isn't suitable by extending the flue would be a big no-no!
My Alpha is fitted on to an internal wall between my flat and the flat next door but the flue goes at rightangles through the external wall. If it couldn't be done that way then it wouldn't be fitted at all as no external wall could accomodate the size of the boiler .d
This is how mine is configured. Installed 2005.
I hope not..
I'm not aware of anything which says it has to be *on* an external wall. But it does need ready *access* to an external wall - both for the flue and for the condensate drain.
You suspect wrongly. It would be very few boilers that can't be used as you wish.
Or the roof.
