This replacement ensures the correct ignition and operation of the burner, preventing gas supply in the absence of flame and guaranteeing the safety of the system.\u003c\/p\u003e\n\n\u003ch3\u003eWhat problem does this replacement solve?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFailure to ignite the burner due to incorrect flame detection.\u003c\/li\u003e\n\u003cli\u003eFrequent burner shutdowns due to lack of signal from the photoresistor.\u003c\/li\u003e\n\u003cli\u003eBurner safety lockout caused by erroneous detection of flame absence.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eModels:\u003c\/h5\u003e\n\u003cp\u003eCompatible with diesel burners for Roca boilers and some Riello models that use the same photoresistor code.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRoca Crono 3L, Crono 2L, Crono 3LS\u003c\/li\u003e\n\u003cli\u003eRiello models compatible with code 20132566\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eFeatures:\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003ePart type: photoresistor (flame sensor)\u003c\/li\u003e\n\u003cli\u003eCompatible brands: Roca, Riello\u003c\/li\u003e\n\u003cli\u003eEquivalent codes: Roca 121307839, 3007839, 20132566, 7704245 (Riello)\u003c\/li\u003e\n\u003cli\u003eDimensions: 9 cm (height) x 7 cm (width) x 17 cm (depth)\u003c\/li\u003e\n\u003cli\u003eMaterial: ceramic component with resistance variable according to light\u003c\/li\u003e\n\u003cli\u003eConnection: terminals for standard electrical wiring in diesel burners\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eRecommendation:\u003c\/h5\u003e\n\u003cp\u003eBefore purchasing, confirm compatibility by checking the original photoresistor code or the exact model of your boiler to ensure a perfect fit and avoid returns.\u003c\/p\u003e","brand":"ROCA","offers":[{"title":"Default Title","offer_id":56664732926330,"sku":"REM-361930004","price":82.74,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0683\/8026\/2676\/files\/3619304_241_sma.webp?v=1773893295","url":"https:\/\/electrotodo.com\/products\/fotoresistencia-quemador-gasoleo-roca","provider":"Electrotodo.es","version":"1.0","type":"link"}
