Convert Fireplace From Gas To Wood

Converting Your Gas Fireplace to a Wood-Burning Fireplace: A Comprehensive Guide

Dreaming of the crackling warmth and rustic charm of a wood-burning fireplace? Many homeowners find themselves captivated by the ambiance and cost-saving potential of wood, especially considering the rising costs of natural gas. But converting your existing gas fireplace to a wood-burning one is a significant undertaking, demanding careful planning, expertise, and adherence to local building codes. This comprehensive guide will walk you through every step of this conversion process, from initial assessment to final inspections.

Is Converting Your Fireplace Feasible? A Preliminary Assessment

Before you even think about purchasing tools and materials, you need a thorough assessment of your current setup and local regulations. Several factors determine the feasibility of conversion:

1. Existing Fireplace Structure:

Type of Fireplace: Is your current gas fireplace built into a masonry chimney (brick, stone, or concrete)? This is crucial. Gas fireplaces often utilize prefabricated units that aren't designed for wood burning and may lack the necessary structural integrity or fire-resistant properties. Converting a prefabricated gas insert is typically not feasible and often unsafe.
Chimney Condition: A thorough chimney inspection is absolutely essential. The chimney needs to be properly sized, structurally sound, and free of obstructions, cracks, or damage. A cracked chimney can be a serious fire hazard. A chimney sweep can provide a professional inspection and report.
Flue Size & Lining: Wood burning requires a larger flue (chimney opening) than gas. A properly sized flue ensures efficient venting of smoke and combustion gases, preventing dangerous carbon monoxide buildup in your home. The flue liner may need to be replaced or relined to accommodate wood burning, which often requires professional intervention.
Firebox Dimensions: The existing firebox (the area where the fire burns) might not be large enough for efficient wood burning. A properly sized firebox allows for adequate airflow and prevents excessive creosote buildup.

2. Local Building Codes and Permits:

Compliance Requirements: Converting a gas fireplace to a wood-burning fireplace almost always requires permits. Your local building department will have specific requirements and regulations you must adhere to concerning chimney construction, fire safety clearances, and ventilation. Obtaining the necessary permits before starting any work is crucial to avoid fines and potential legal issues. Failure to comply can result in significant penalties.
Inspections: Expect inspections at various stages of the conversion process, particularly before, during, and after construction. These inspections ensure compliance with local building codes and safety standards.

3. Cost Considerations:

Material Costs: The cost of materials can vary greatly depending on the extent of the work needed. You'll need a new firebox, potentially a new flue liner, a new damper, and possibly other fire-resistant materials.
Labor Costs: Unless you possess significant construction and masonry skills, you'll likely need to hire a professional to perform at least some aspects of the conversion. The cost of professional labor can be substantial.
Permitting Fees: Don't forget to factor in the costs associated with obtaining the necessary permits and inspections.

The Conversion Process: A Step-by-Step Guide

If your initial assessment suggests the conversion is feasible, you can proceed with the following steps:

1. Demolition and Preparation:

Gas Line Disconnection: A qualified gas technician should disconnect the gas supply line to your fireplace. This step is crucial for safety and should never be attempted by someone lacking the necessary training and experience.
Removal of Existing Components: Carefully remove the gas fireplace components, including the burner, logs, and any other related parts. This process may require specialized tools and knowledge.
Chimney Inspection and Cleaning: Before proceeding, have your chimney thoroughly inspected and cleaned by a certified chimney sweep. They will identify any issues and ensure the chimney is ready for wood burning.

2. Installation of New Wood-Burning Components:

Firebox Construction or Replacement: Depending on the condition of your existing firebox, you may need to construct a new one or replace the existing one with a suitable wood-burning firebox. This often requires significant masonry skills.
Installation of a New Damper: A damper is essential for controlling airflow and preventing heat loss when the fireplace is not in use. A well-functioning damper is crucial for efficient burning and safety.
Flue Liner Installation (if needed): If your existing flue liner isn't suitable for wood burning, a new flue liner must be installed. This is a complex process requiring expertise to ensure proper fit and venting.

3. Fireplace Construction and Finishing:

Masonry Work (if necessary): This may involve repairing or rebuilding parts of the fireplace structure, ensuring proper clearances and fire-resistant properties. This step often necessitates the expertise of a skilled mason.
Finishing Touches: Once the new wood-burning fireplace is installed, you may wish to add finishing touches such as a new hearth, mantel, or facing.

4. Final Inspections and Safety Checks:

Building Inspections: Schedule a final inspection with your local building department to ensure compliance with all relevant codes and regulations.
Chimney Sweep Inspection: After installation, a final chimney sweep inspection verifies the proper functioning of the chimney and flue.
Carbon Monoxide Detector: Install and test a carbon monoxide detector near the fireplace. This essential safety device alerts you to potentially dangerous carbon monoxide levels.

Choosing the Right Wood for Your Fireplace

Once your wood-burning fireplace is installed, selecting the right type of wood is crucial for safety and efficiency.

Seasoned Hardwood: Opt for seasoned hardwood like oak, maple, or hickory. These woods burn hotter and longer, producing less smoke. Avoid using green wood, as it contains excessive moisture, leading to poor combustion, excessive creosote buildup, and potential chimney fires.
Proper Storage: Store your firewood in a dry, well-ventilated area to prevent moisture absorption.

Safety Precautions: A Wood-Burning Fireplace Requires Diligence

Using a wood-burning fireplace involves inherent risks that must be mitigated.

Chimney Cleaning: Regular chimney cleaning is paramount, usually once or twice a year. Accumulation of creosote is a significant fire hazard.
Fire Safety: Always supervise a fire, never leave it unattended. Keep flammable materials away from the fireplace. Have a fire extinguisher readily available.
Carbon Monoxide Detection: Ensure your carbon monoxide detector is working correctly.
Proper Ventilation: Ensure adequate ventilation in the room where the fireplace is located.
Children and Pets: Keep children and pets away from the fireplace area to prevent burns or injuries.

Is Converting a Gas Fireplace to Wood Worth It?

The decision to convert your gas fireplace to wood depends on various factors. Weigh the costs of conversion against the potential savings on fuel and the aesthetic appeal of a wood-burning fireplace. Consider your lifestyle, local regulations, and the condition of your existing fireplace structure. A careful evaluation of these factors will help you determine whether the conversion is the right choice for you.

This comprehensive guide offers a starting point for your conversion project. Remember that this is a complex undertaking that often requires professional expertise. Always prioritize safety and compliance with local building codes. By carefully planning and executing the conversion process, you can enjoy the warmth, ambiance, and potential cost savings of a beautiful wood-burning fireplace in your home. Remember to consult with professionals throughout the process to ensure a safe and successful conversion.
