Finlandia / Harvia Part # FH106 or ZSV-320 Rock Guard for KV Model Heater is a purpose-built protective frame that keeps sauna stones securely positioned on top of your KV heater, supporting both safety and consistent heat production. Designed to match the contours of the KV model, it fits cleanly into place and helps prevent rocks from shifting, tipping, or falling when the heater is in use or when water is applied for steam. Its durable, heat-resistant construction withstands the intense temperatures of daily sauna operation while preserving proper airflow through the stone bed for balanced heating. Easy to install and sized for an exact fit, this replacement guard is an effective way to restore stability and maintain reliable performance when the original component becomes worn or damaged.
