Lopi FL, LX, X Owner's manual

Hello! I've reviewed the user manual for the LOPI fireplace inserts, including models X, FL, and LX. This document provides detailed information on installation, usage, and maintenance. I'm familiar with features like refractory baffle, air controls, and safety precautions. Ask me questions about your new device!
Can these fireplace inserts be installed in metal or zero clearance fireplaces?

What is the purpose of the refractory baffle?

What type of wood should be used in these inserts?

How often should the chimney be inspected for creosote?
