As shown in the Pureheat wiring schematic, the control panel integrates dedicated GFI protection on both Line 1 and Line 2 circuits, and this inline unit serves that same protective function within the broader heater electrical system. A failed or tripped GFI can result in loss of power to downstream circuits, preventing the pump, burner, or other control panel functions from operating. Replacing a faulty inline GFI restores proper ground fault protection and allows normal heater operation to resume.\u003c\/p\u003e\n\n\u003cp\u003eThis part is compatible with the following Wacker Neuson hydronic heater models:\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eHHS 1101\u003c\/li\u003e\n  \u003cli\u003eHHS 1701\u003c\/li\u003e\n  \u003cli\u003eHHS 1251\u003c\/li\u003e\n  \u003cli\u003eHHS 2200\u003c\/li\u003e\n  \u003cli\u003eHHS 2202\u003c\/li\u003e\n  \u003cli\u003eHHS 2502\u003c\/li\u003e\n  \u003cli\u003eHHS 3000\u003c\/li\u003e\n  \u003cli\u003eHHS 3002\u003c\/li\u003e\n  \u003cli\u003eHHS 3004\u003c\/li\u003e\n  \u003cli\u003ePureheat\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eGenuine Wacker Neuson OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Wacker Neuson","offers":[{"title":"Default Title","offer_id":43397342691376,"sku":"WACKER-5000166512","price":187.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/5000166512.jpg?v=1784033564","url":"https:\/\/cce-industries.com\/products\/wacker-neuson-inline-gfi-5000166512-for-hydronic-air-surface-heaters","provider":"CCE Industries","version":"1.0","type":"link"}
