Power Shot models.

There are a lot of restrictions on just where the
flue gases can be exhausted to.
Read the instruction sheets carefully and also ask
the town inspector what they require.
Another possible in your case is to use the boiler
to heat domestic hot water. There are a couple ways
to do this. Ask the heating contractor what they
recommend. Yes, this keeps the boiler on standby
all summer long, but a well-insulated boiler will
have small heat losses.
One note on the exhausts from boilers and heaters:
the induced flue blower does make noise! Don't
locate the exhaust outlet where this will be an
annoyance.
