It replaces the combustion air blower on the LP version of that heater.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the blower does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA modern pool heater does not simply light a burner. It first pushes a measured volume of air through the burner system and confirms that airflow is present before it will allow gas. The blower is what supplies that air. If it fails, or if its airflow drops below what the control expects, the heater locks out and never gets as far as ignition.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCheck fuel and size first\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis kit is specific to the 333 size running on propane. The natural gas version and the other heater sizes take different kits, so read the rating plate rather than working from the model name alone.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eA note on the brand\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eYou will see this part under two names. It is listed as Sta-Rite with the Max-E-Therm heater line, and the source also describes it as a Pentair part filed under the MasterTemp burner system. Those heater lines share the hardware, so both references point at the same kit.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48627886325972,"sku":"STA-151-0255","price":723.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_20fc9ea5-6715-4fca-9757-6e8b50d20047.png?v=1788729624","url":"https:\/\/www.activepoolsupply.com\/products\/blower-kit-lp-sr333","provider":"Active Pool Supply","version":"1.0","type":"link"}
