To ensure the safety of using a stove heater in your home, perform regular maintenance by cleaning and inspecting the stove and chimney to prevent creosote buildup. Ensure proper ventilation to avoid carbon monoxide accumulation, and install a carbon monoxide detector for added safety. Keep flammable materials at a safe distance from the stove to prevent accidental fires. Additionally, use only the recommended fuels to ensure efficient operation and avoid hazardous emissions.
