I had a
wood stove for twenty years and tried to keep it burning constantly in winter. It sat about a foot from the brick chimney. I wouldn't worry so much about the brick as the paint on the brick. My chimney was also painted. What I worried most about was the wooden floor below the stove. I set mine on a layer of oversize brick. Not pavers, the ones with the hollow holes. They were on edge. The problem I had was dust and dirt between the brick. There was no mortar so they got dirty. I'd slide some out and leave the ones the stove sat on and sweep up the dirt. I'd suggest a piece or marble or granite on top of the brick. My cat liked to lay under the stove. I guess when it was not burning wide open or when the
ash needed cleaned out.
I only burned hardwood. No pine. Watch the chimney. I checked it with a mirror looking up from the clean out, in daylight. I found the one the gas furnace was hooked to was full of mortar debris, which must of fallen from the chimney liner mortar. The sand had filled up and I couldn't believe there was a way for the fumes to clear. On my current house the furnace flue was paper thin. I think everyone needs to check their flues and their chimneys occasionally. Two houses, two huge problems. Lucky I'm alive.
Anyway watch the creosote, burn smart, but enjoy the stove.
