Replacing Natural Draft Boiler - What Are My Venting Options? (Toronto)
I'm looking to replace my boiler and I need some advice. I'm in Toronto, in an older (1940s built) house. My house sits on my neighbour's property line. My current boiler is in my basement and vents up the chimney in a natural draft configuration. It is common vented with my HWT.
Some contractors told me that the best solution (based on space constraints) is a direct vent configuration onto/above my neighbour's driveway. But I don't want the inherent liability.

If I got a combi boiler like the Viessmann Vitodens 100, is there a way I could have both the intake and exhaust running up the chimney?
I'm trying to avoid intake coming from my basement, as I don't want to have to seal up my boiler room as per TSSA regulations.
