Finlandia / Harvia Part # FH90 or ZSK-683 Rock Guard Grill for Top of Heater is designed to keep sauna stones securely contained at the top of compatible Finlandia and Harvia heaters, supporting both safety and efficient heat circulation. By forming a sturdy barrier around the rock bed, this grill helps prevent stones from shifting or sliding off the heater during regular use or when water is ladled onto the rocks. Crafted from durable, heat-resistant materials, it stands up to the intense temperatures and steam found in traditional sauna rooms. The precisely formed guard fits the heater’s contour, promoting even airflow through the stones for consistent, comfortable bathing conditions. As a genuine replacement part, this rock guard grill is ideal when refurbishing an older unit or completing a new installation, helping protect bathers while preserving the performance of your heater.

  • Rock Guard Protection – Secures sauna stones on top of the heater, preventing them from shifting or falling during use, which enhances both safety and consistent heat distribution.
  • Enhanced Safety – Reduces the risk of accidental contact with loose rocks, protecting users and preventing potential damage to the heater or sauna interior.
  • Durable Heat-Resistant Construction – Built to withstand high temperatures and repeated exposure to steam, ensuring long-lasting performance in demanding sauna environments.
  • Precise Fit for Compatibility – Engineered to match Finlandia and Harvia heater contours, supporting even airflow through the rock bed for consistent and comfortable sauna heat.
  • Easy Installation – Simple to install as a genuine replacement part, making it ideal for refurbishing older units or completing new sauna heater setups.
  • Non-Returnable Part – Ensures authenticity and safety, requiring verification of compatibility to maintain reliable heater performance and user protection.
