Hi our newly purchased home has a heritage renaissance insert in the basement.  The chimney is currently sealed with aluminum tape over the clay liner... I am thinking of getting the chimney wett certified; I will probably need a new liner installed.... anybody have any feedback of these inserts.. I found the manual online says it has a secondary combustion system.
I just don't know if I should use it or invest in a pellet insert or leave as is
