Yes, there is multiple flueing options for boilers (all listed in the installation manual)
But be aware, since 26th of July 2009 it would be an offence to carry out this work yourself if your not RGII registered (15000euro or 3 years) and either way if not done correctly could lead to a life threatening situation (yes seriously)
Maybe suggest get a local installer to have a look, or maybe MI flues can help you out.
