Which maintenance task is recommended weekly for a pellet hearth system?

Burning hot fires once a week is a recommended maintenance task for a pellet hearth system because it helps to ignite and burn off any residual creosote or buildup in the system, ensuring that the appliance operates efficiently. This practice serves to maintain a cleaner combustion environment and can aid in the prevention of operational issues that may arise from excessive buildup, thereby promoting the safe operation of the appliance. Running the system at higher temperatures also allows for more complete combustion of the pellets, which reduces the amount of soot and ash produced.

In the context of other maintenance tasks, cleaning the chimney flue is typically a less frequent activity and may be required only a few times a year depending on usage and building codes, while inspecting gas lines is essential for gas-fired appliances but isn't a weekly task for a pellet system. Cleaning the combustion air passage is indeed important but usually falls under regular maintenance routines rather than a strict weekly task.
