Condición de chimenea y conducto
Punto críticoCómo verificar
1. Inspect chimney exterior — look for cracked or missing mortar, leaning, damaged cap
2. Check chimney cap — should have a cap with spark arrestor screen
3. Open and close damper — should move freely and seal when closed
4. Look up the flue with a flashlight — should be clean, no creosote buildup
5. Check for creosote buildup — more than 1/8" layer requires cleaning
6. Verify flue liner is intact (no cracks, gaps, or missing sections)
7. Check hearth extension — minimum 16" in front, 8" to each side
8. Verify combustible materials are at least 6" from the fireplace opening
9. Check for flashing at chimney-to-roof junction
