Hello, I am having a new house built & had it drywalled and forget to put a vent hose on the fireplace & cant get to it now to do it, it is now all inclosed. Is it very important,or am i going to have to cut into the wall or what,i messed up? Thanks Darwin.
A "vent hose?" Meaning a chimney duct for the fireplace to vent the smoke from the fire? (It should not be a "hose" for flaming embers and smoke.) Where do you propose the smoke and flying embers from the fireplace go if you do not have a "vent hose:" into the wooden walls?!?!
If that's what you mean, then, yes, you need to tear through the drywall.
