All the Baxi ones have *all* pipes in a row at the bottom.
AFAIK most are the same.
Go on line and look at the manufacturers web sites, they have all the
information there.

Perhaps your CORGI-mate could suggest a boiler where the pipe
connections *are* actually at the top. I'm on nodding terms with various
models each by Vaillant, Worcester-Bosch, Sime, and Ideal - all of which
have bottom connections. In fact the W-B has provision to permit the
pipes to approach from the top too, if necessary.
