Made box to slot in fireplace opening. Dried flowers or something would go in. Used thermal blocks to reduce size of opening then plaster skimmed. There was a small water pool in box from condensation every morning and it was winter. I made small vent in fireplace side wall as hidden and water stopped.

You need a chimney vented bottom and top. Becouse chimneys get batterd whith rain the moisture that goes in to chimney needs to dry. The idea is to get air circulation going otherwise it going to get trapped in ther. Told you before stick to selling stuff

Technically shouldn't DND on solid walls but seen it done in Bedfordshire many times with few problems
This example we don't know if its a terraced or detached
