I just purchased a home, and I am looking to install a new gas powered boiler. The current boiler vents into 100 year old chimney.
To my surprise, there is an unobstructed view from the bottom of the chimney, viewed through the clean-out door, to the top. Shouldn't there be a chimney liner that attaches to my current boiler that obstructs this view?
Also, the current flue is secured only with masonry (see zoomed in photo). Is this a proper installation? Can I vent the new boiler the same way?
