I was thinking about attaching a brick BBQ pit 2 the bricks that make up my fireplace. Is it too close?

the fireplace is all brick, and about 8 feet wide....want to attach the BBQ to the fireplace using the fireplace as on side of the BBQ...no overhanging trees or patio over future BBQ pit...but about 10 - 15 feet from back door....I was thinking about attaching a brick BBQ pit 2 the bricks that make up my fireplace.

That should be an excellent location as long as you can keep it structurally stable. Most municipal fire departments reccomend about 3-5 feet of clearance between a contained flame and a structure. Therefore 10 feet between your proposed BBQ pit and the building is more than sufficient. The only thing to really consider, is your usual wind directions. For example: It the wind going to blow a bunch of smoke or possibly loose ashes through your back door on a nice day?
