How To Install An Outdoor Wood Burning Furnace

An outdoor wood-burning furnace is a valuable investment for homeowners seeking a cost-effective and environmentally friendly way to heat their homes. These furnaces use readily available wood fuel to generate heat that can be circulated throughout a dwelling, reducing reliance on traditional heating systems. However, installing an outdoor wood furnace requires careful planning and adherence to local building codes and regulations. This article will guide you through the essential steps involved in installing an outdoor wood-burning furnace.

1. Planning and Preparation

Before beginning any installation, it is crucial to plan and prepare adequately. This includes obtaining the necessary permits, choosing the right location, and gathering the required materials.

One of the first steps is to contact your local building department to inquire about permit requirements for installing an outdoor wood furnace. Some areas may require specific permits, inspections, and adherence to specific code requirements. Understanding these regulations beforehand will help ensure a smooth and compliant installation process.

Selecting the right location for the furnace is an important consideration. The furnace should be placed a safe distance from any structures, trees, and vegetation, and should have adequate access for fuel delivery and maintenance. The location should also consider prevailing winds to minimize smoke impact on neighboring properties.

Once the location is determined, it is essential to gather the necessary materials for the installation. This typically includes a concrete pad for the furnace, a chimney, pipe insulation, venting materials, and any other required components specified by the furnace manufacturer.

2. Foundation and Chimney Installation

A solid foundation is crucial for supporting the weight of the outdoor wood furnace and ensuring its stability. The most common foundation type is a concrete pad, which provides a durable and level base for the furnace.

The concrete pad must be large enough to accommodate the furnace and allow for adequate clearance around it. The pad should also be sloped slightly away from the furnace to prevent water accumulation. The concrete pouring process should be carried out carefully, ensuring the pad is level and securely anchored to the ground.

Installing a chimney is another essential aspect of the installation process. The chimney should be constructed using approved materials and meet local building codes. The chimney should be tall enough to provide adequate draft for the furnace and should be properly insulated to prevent heat loss.

The chimney should be connected to the furnace in accordance with the manufacturer's instructions. Ensure the connection is tight and secure using appropriate sealing materials. The chimney should also be inspected regularly for any signs of damage or deterioration.

3. Furnace Installation and Connection

Once the foundation and chimney are in place, the furnace itself can be installed. This typically involves positioning the furnace on the concrete pad and securing it to the ground using bolts. The furnace should be level and properly supported to ensure stability.

Connecting the furnace to the heating system is a crucial step. This involves running pipes from the furnace to the heat exchanger within the home. The pipes should be sized correctly to carry the heated water or air efficiently and effectively. It is advisable to use insulated pipes to minimize heat loss during circulation.

The furnace also needs to be connected to a water source for providing water to the heating system. This connection should be properly plumbed and equipped with a pressure relief valve to prevent overpressure in the system.

Finally, the furnace needs to be connected to the electricity supply for the control panel, blower fan, and any other electrical components. Ensure that all electrical connections are properly grounded and meet local electrical codes.
