Hi,
We are considering DIY installation of a flex liner (22', 6") for a wood insert.
There are blue stones installed on the top of our chimney that have to be removed for the top down installation.
Therefore, we are thinking about the bottom up installation. Damper opens to the chimney flue only 6".
We will need to remove not only damper plate but also damper metal frame to make opening bigger.
What is sufficient opening size for the bottom up installation? Please advise us. Thank you.
