Frequently Asked Questions

How often should I have my chimney cleaned?

Chimney cleaning frequency depends on use and fuel type. Wood-burning fireplaces need cleaning at 1/8" creosote buildup, typically after burning 1-2 cords. Gas fireplaces require cleaning every 2-3 years to remove debris and ensure proper venting. Heavy users should clean after each cord burned. The National Fire Protection Association recommends annual inspections regardless of cleaning needs to identify developing problems early.

What type of smoke detector is best near a fireplace?

Photoelectric smoke detectors work best near fireplaces because they respond faster to smoldering fires while producing fewer false alarms from fireplace use. Install detectors 10-15 feet from fireplaces on ceilings or high walls. Dual-sensor models combining photoelectric and ionization technology provide comprehensive protection. Replace all detectors every 10 years and test monthly to ensure proper operation.

Can I burn manufactured logs with real wood?

Never mix manufactured logs with real wood in the same fire. Manufactured logs burn differently than cordwood, producing different temperatures and chemical reactions. Burning them together can cause excessive heat, increased creosote, and unpredictable burning patterns. Use one or the other per fire. If switching between types, let the fireplace cool completely and remove all residue before changing fuel types.

What's the safe temperature for fireplace glass?

Fireplace glass temperatures vary widely by type and operation. Traditional fireplace glass can exceed 500°F, causing instant severe burns. Modern cool-touch technology limits surface temperatures to 172°F or less. Gas fireplace glass typically runs 300-500°F during operation. Always assume glass is dangerously hot unless equipped with certified cool-touch technology. Install barriers preventing contact regardless of glass type.

How do I know if my fireplace is safe to use?

Professional inspection provides the only reliable safety assessment. Warning signs requiring inspection include: visible cracks in firebox or flue, damaged damper mechanisms, missing mortar joints, rusted components, animal sounds or debris, strong odors when not in use, or previous chimney fires. If more than two years have passed since professional inspection, schedule one before use. Never use a questionable fireplace hoping for the best.

Creating a Culture of Fireplace Safety

Fireplace safety requires ongoing vigilance, proper equipment, and family participation. Combining annual professional maintenance with daily safe practices prevents fires while maximizing enjoyment of your fireplace.
