Installing an outdoor wood burning furnace can be a cost-effective and efficient way to heat your home or other outdoor structures. In this article, we will provide a clear and concise guide on how to install an outdoor wood burning furnace. Whether you’re technically inclined or new to wood burning, this guide will help you understand the process.
1. Selecting the Right Location
Choosing the right location for your outdoor wood burning furnace is the first critical step. Consider the following factors:
Distance from Structures: The furnace should be placed a safe distance away from your home, garage, or any other buildings. Typically, a minimum of 30 feet is recommended to ensure safety.
Ventilation: Ensure there’s adequate ventilation around the unit. This prevents smoke and fumes from accumulating in the area.
Access to Fuel: Place the furnace near a convenient wood storage area to minimize effort when loading fuel.
2. Prepare the Foundation
A stable and level foundation is essential to support the weight of the furnace. You can use a concrete pad or a sturdy base of concrete blocks. Ensure that the foundation is level to prevent any tilting of the furnace.
3. Install the Furnace
Here are the basic installation steps:
Position the Furnace: Place the wood burning furnace on the prepared foundation.
Chimney Placement: Determine the location for the chimney or exhaust pipe. This will vent the combustion byproducts safely away from the area.
Connect the Plumbing: Install the piping and plumbing that connects the furnace’s heat exchanger to your home’s heating system. Ensure all connections are secure and well-insulated to minimize heat loss.
Electrical Connection: Some units require an electrical connection for features like blowers or circulation pumps. Ensure that the electrical setup adheres to local electrical codes and safety standards.
4. Install the Chimney
The chimney is a crucial component for safe ventilation. Here’s how to install it:
Vertical Installation: The chimney should be installed vertically to allow for proper draft and efficient venting. It should extend above the peak of your home or any nearby structures.
Clearance: Maintain proper clearances from combustible materials, following manufacturer recommendations and local codes.
Weather Protection: Install a weather cap on the chimney to prevent rain, snow, or debris from entering.
5. Fuel Supply and Loading
Before using your outdoor wood burning furnace, ensure a steady supply of seasoned firewood with a moisture content of around 20% or less. Hardwoods like oak, maple, and hickory are ideal choices due to their higher energy content and slower burn rate. Loading the firebox with the right type of wood ensures efficient combustion and effective heating.
6. Safety Considerations
Safety is paramount when installing and using an outdoor wood burning furnace:
Follow Manufacturer Guidelines: Always adhere to the manufacturer’s installation and operation guidelines.
Carbon Monoxide Detectors: Install carbon monoxide detectors in your indoor spaces to ensure safety.
Chimney Cleaning and Maintenance: Schedule regular chimney cleaning and professional inspections to prevent creosote buildup and maintain efficient operation.
Conclusion
Installing an outdoor wood burning furnace can be a rewarding project that provides efficient heating for your outdoor spaces. By carefully selecting the location, preparing a solid foundation, and following safety guidelines, you can enjoy the benefits of this cost-effective and sustainable heating solution.
