parallel is better in my opinion,
if you have only one flue, code requires
one flue for each appliance, unless the unit
is a dual fuel unit.
is to simply use one or the other heating unit and
physically disconnect the units flue piping and
set it aside and put the other flue pipe connection
in its place.
