Technical Specifications

  1. Dimensions: The Merrimack fireplace insert typically measures around 29 inches in width, 22 inches in height, and 15 inches in depth. Ensure that your fireplace opening can accommodate these dimensions for a secure fit.

  2. Heating Capacity: This wood-burning insert offers a substantial heating capacity, producing up to 55,000 BTUs (British Thermal Units) of heat per hour. It is suitable for heating large rooms and even entire homes when properly positioned.

  3. Emissions: The Merrimack insert is EPA-certified, meaning it meets or exceeds environmental standards for emissions. It utilizes advanced combustion technology to reduce emissions and maximize efficiency, making it an eco-friendly heating solution.

  4. Burn Time: One of the strengths of the Merrimack insert is its extended burn time. It can often burn for 8 hours or more on a single load of wood, thanks to efficient combustion and a spacious firebox.

  5. Adjustable Air Controls: The unit features adjustable air controls, which allow you to fine-tune the combustion process. These controls impact burn rate and heat output, providing flexibility in maintaining your desired temperature.

Proper Operation

  1. Installation: Proper installation is essential for the Merrimack’s performance and safety. It’s advisable to seek professional assistance if you are uncertain about the installation process. Ensure that the insert fits securely into your fireplace opening, while also maintaining recommended clearances.

  2. Firewood Selection: Use well-seasoned hardwoods like oak, maple, or hickory for the best results. Properly seasoned wood should have a moisture content of around 20% or less to ensure efficient combustion and minimize creosote buildup.

  3. Loading Wood: When loading wood into the Merrimack insert, stack it loosely to allow for proper airflow. Avoid overloading the firebox, as this can hinder efficiency and result in increased emissions.

  4. Air Controls: Experiment with the adjustable air controls to find the right balance between burn rate and heat output. The primary air control regulates combustion air entering the firebox, while the secondary air control enhances combustion efficiency.

  5. Cleaning and Maintenance: Regular cleaning is essential to maintain the Merrimack’s efficiency. Clean the firebox, flue, and chimney to remove creosote buildup, which can pose a fire hazard. Follow the manufacturer’s instructions for proper maintenance.

  6. Safety: Safety is paramount when operating the Merrimack insert. Ensure that you have smoke and carbon monoxide detectors in your home, and that your chimney is in good condition. Keep flammable materials away from the unit and maintain adequate clearance to prevent overheating.
