This article presents a detailed overview of the installation and operational considerations for Earth Stove models, particularly the 1500HT wood-burning stove and various pellet stove models like the MP40, Model 1000, and Traditions series. The information is derived exclusively from manufacturer manuals, technical specifications, and user forums, with an emphasis on accuracy and adherence to official documentation.
Overview of Earth Stove Models and Installation Requirements
Earth Stove offers a range of wood-burning and pellet-burning stoves, each with distinct design, operational, and installation requirements. The wood-burning 1500HT model, for example, is an EPA-certified stove designed for residential use and must be installed by a qualified installer. According to the installation manual, the 1500HT must be placed in a central location to maximize heat distribution through convection. Additionally, the manual emphasizes the importance of proper clearance—6 inches (152 mm) from the sides and top of the stove, and 2 inches (51 mm) from the rear—to accommodate the masonry structure that houses the stove. The stove must also be installed on its original listed legs or base unless otherwise specified by OMNI Testing Laboratory.
Pellet stoves from Earth Stove, such as the MP40 and Model 1000, employ the Natural Fire bottom feed system with a cup and auger motor to deliver pellets to the burn pot. These models also feature an adjustable draft/combustion fan and are part of a broader range of stoves including the Traditions series, which uses cast iron construction and a Traeger-developed positive pressure bottom feed system. The Traditions series was later influenced by the Whitfield negative pressure top feeding system in some models, particularly the T300P.
Installation of the 1500HT Wood-Burning Stove
The 1500HT wood-burning stove requires meticulous installation to ensure both performance and safety. The manufacturer’s manual outlines several key steps and precautions:
Selecting the Stove Location
The location of the stove is critical to its efficiency and safety. The manual recommends a central location within the home to optimize heat distribution via convection. The stove must be installed on a stable, level surface, with adequate space to allow for proper air circulation and maintenance access. It is also important to consider the distance from combustible materials and structural elements, adhering to the minimum clearance specifications.
Chimney and Ventilation Requirements
A properly installed chimney is essential for the safe operation of the 1500HT. The stove must be connected to either a properly built masonry chimney or a factory-built chimney that ensures consistent draft under various weather conditions. The manual specifies that the chimney must extend at least 3 feet (914 mm) above the roof penetration and be at least 2 feet (610 mm) higher than any roof surface within 10 feet (305 cm). Local building codes may impose additional requirements, so it is advisable to consult with local officials during the installation process.
Grounding Requirements for Manufactured Homes
For stoves installed in manufactured (mobile) homes, the manual mandates that the stove must be grounded. This is achieved by attaching a No. 8 copper wire, at least 18 inches (457 mm) in length, from the stove to the chassis of the manufactured home. This grounding procedure is a regulatory requirement to prevent electrical hazards.
Flue Pipe Installation
The flue pipe must be securely fastened to the stove using sheet metal screws. The manual specifies that three pre-drilled holes are provided in the flue collar for this purpose. Additional sections of single wall pipe should also be fastened with at least three sheet metal screws per section to ensure structural integrity and prevent leaks. The pipe should be installed with as few bends as possible to maintain optimal airflow and reduce the risk of smoke accumulation.
Installation of Earth Stove Pellet Stoves
Earth Stove pellet stoves, such as the MP40 and Model 1000, are designed for efficient and automated operation. These models are equipped with advanced features like the Natural Fire bottom feed system and adjustable combustion fans. However, their installation also requires careful attention to detail to ensure optimal performance and safety.
Natural Fire Bottom Feed System
The MP40 model, for example, features the Natural Fire bottom feed system, which uses a cup and auger motor to feed pellets from the rear to the burn pot. This system is designed to provide a natural fire appearance while ensuring consistent and efficient combustion. The installation manual emphasizes the importance of ensuring that the auger motor and feed system are correctly aligned and securely mounted to avoid operational issues.
Clearance and Structural Requirements
Like the 1500HT, pellet stoves also require adequate clearance from combustible materials and structural elements. The manual for the MP40 specifies that the stove should be installed on a stable and level surface, with sufficient space for maintenance and air circulation. It is also important to ensure that the stove is installed in accordance with the manufacturer’s specifications for the base or legs.
Electrical and Control System Installation
Pellet stoves require a stable electrical connection to power the auger motor, combustion fan, and control panel. The installation manual for the MP40 and other models outlines the wiring requirements, including the use of a dedicated circuit and proper grounding. The control panel must also be installed in a location that is easily accessible for operation and monitoring.
Chimney and Exhaust Requirements
A properly installed chimney is critical for the safe operation of a pellet stove. The manual recommends using a factory-built chimney that is compatible with the stove’s exhaust system. The chimney must be installed with the correct slope to ensure proper draft and must be sealed to prevent leaks. The manual also advises against the use of grates or other methods to elevate the fire, as this can interfere with the combustion process and increase the risk of overheating.
Maintenance and Operational Considerations
Regardless of the model, regular maintenance is essential for the safe and efficient operation of Earth Stove wood-burning and pellet stoves. The manufacturer’s manuals emphasize the importance of routine cleaning, inspection, and part replacement to prevent malfunctions and extend the life of the stove.
