John-

Find yourself a knowledgable installer.

Just about "anything" can be done, undone, repaired, replaced or
retrofitted.

I read Bubba's link, if you want to educate yourself on exhaust vent
sizing, read it.

Done wrong, the installation might give you problems;

Done right it will be fine. It's all about getting the "plumbing"
right.

cheers
