Unsafe Fireplaces

Common Problems:

• Use of “mix and match” components.
• Unsealed gas pipe penetrations.
• Insufficient clearances between fireplaces and combustible materials.
• Missing or incomplete installation of firestops between floors.
• Use of non-approved decorative chimney terminations.
• Insufficient chimney height.

Potential Damage:

• Fire hazard.
• Voiding of manufacturer’s guarantees.
• Embers may escape into framed areas.
• Inadequate fire protection.
• Smoke may enter living spaces.

Proper Solutions/Construction:

• Use approved laboratory-tests (i.e. Underwriters Laboratories, Inc. ) components by a single manufacturer.
• Use refractory (fireproof) cement to seal gas pipe penetrations through the fire box.
• Follow manufacturer’s installation instructions regarding required clearances from framing and other combustible materials.
• Use only approved, listed, decorative chimney terminations.
• Use the “2ft. in 10-ft. height rule” for chimney heights (Uniform Building Code, Section 3703(f) & Table 37-B).
