Why Your Oil or Gas Chimney Flue Needs Just As Much Attention As a Wood-Burning One

Introduction

Homeowners often think only wood-burning fireplaces need chimney service. The truth? Your furnace or boiler chimney is working harder than you think — and neglecting it could put your family at risk.

Gas & Oil Chimneys Are Not Maintenance-Free

• They produce less soot but more acidic moisture.
• That moisture eats away at clay liners and mortar joints.

The Silent Threat of Carbon Monoxide

• Even small cracks in a flue allow CO (carbon monoxide) to escape.
• CO is odorless, colorless, and deadly — and most leaks go unnoticed without inspection.

Common Oil & Gas Flue Problems

• Flaking clay tile liners.
• Corrosion on metal liners.
• White “salt-like” stains (efflorescence) indicating water damage.

Why Professional Inspections Matter

• Only a trained tech with proper equipment can spot early deterioration.
• Video scans are critical here — flashlight checks often miss CO leakage paths.
