Register plates, often overlooked components in wood burning stove installations, play a crucial role in safety, efficiency, and functionality. In this guide, we will explore the technical details and practical aspects of register plates for wood burning stoves to provide clear and concise information for both technical and non-technical readers.
What is a Register Plate?
A register plate, also known as a closure plate, is a horizontal barrier installed above the stove within the chimney or flue system. Its primary purposes are to:
Seal the Flue Opening: A register plate seals off the opening where the stovepipe or flue pipe enters the chimney or flue liner. This helps prevent heat loss, cold downdrafts, and the escape of smoke or harmful gases into the room.
Protect Combustibles: It shields combustible materials, such as wooden beams or rafters in the ceiling, from excessive heat generated by the stovepipe.
Improve Draft Control: A well-designed register plate can help control the draft within the chimney, promoting efficient combustion and reducing the risk of backdrafts.
Key Technical Considerations
When dealing with register plates for wood burning stoves, it’s essential to pay attention to these technical details:
Material: Register plates are typically made from non-combustible materials, such as steel, stainless steel, or Vermiculite board. These materials can withstand high temperatures and provide effective insulation.
Sizing: The register plate should be accurately sized to fit the dimensions of your fireplace opening and accommodate the stovepipe. Proper sizing ensures a snug fit, sealing off the flue opening effectively.
Access Hatches: Some register plates include access hatches or inspection doors. These are beneficial for chimney maintenance, such as chimney sweeping or flue liner inspection.
Sealing: The edges of the register plate must be sealed properly to ensure an airtight fit. This prevents smoke and fumes from escaping into the room and maintains optimal draft control.
Installation Steps
Measure the Fireplace Opening: Accurately measure the width and depth of your fireplace opening to determine the correct size for your register plate.
Cut or Adjust the Plate: If your register plate is not pre-cut to the right size, cut or adjust it as needed, ensuring it fits snugly within the opening.
Install the Plate: Place the register plate above the stove, sealing the flue opening. Make sure it is secure and flush with the fireplace opening.
Seal the Edges: Use heat-resistant sealant or fire cement to seal the edges of the register plate, ensuring an airtight seal.
Chimney Sweeping Access: If your register plate includes an access hatch, install it securely, making sure it is easy to open and close.
Maintenance
Regular maintenance of your register plate is essential to ensure its ongoing effectiveness. This includes:
Inspecting for Cracks or Damage: Periodically check the register plate for cracks, warping, or damage. If any issues are detected, replace the plate promptly.
Maintaining Seals: Reapply heat-resistant sealant or fire cement if you notice any deterioration or gaps around the edges.
Conclusion
Register plates for wood burning stoves are vital components in ensuring the safety and efficiency of your stove installation. They seal the flue opening, protect combustibles, and enhance draft control. Pay close attention to the material, sizing, and sealing during installation, and perform regular maintenance to keep your register plate in excellent condition. Properly installed and maintained, a register plate will help you enjoy the warmth and comfort of your wood burning stove while keeping your home safe and free from smoke and fumes.
