{"product_id":"1-2-propane-combination-valve","title":"Raypak Genuine OEM Propane Gas Combination Valve For Model 53, 53A, 406A Millivolt Pool Heater, 1\/2\"","description":"\u003cp\u003eThe Raypak 003899F is the propane gas combination valve with 1\/2 in. connections, used on the millivolt pool heaters Raypak names as model 53, 53A and 406A. It is the genuine OEM part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the valve does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA combination valve is the single gas control for the heater. The manual cock, the pilot safety circuit and the main valve all sit in one body, so gas to the pilot and gas to the burners are governed by the same part. On a millivolt heater there is no electronic ignition board behind it: the pilot generates the small voltage that holds the valve open, which is why a tired valve or a weak pilot generator shows up as a heater that lights and then drops out.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eConfirm the fit before ordering\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is the propane valve, not the natural gas one, and fitting the wrong gas type is not a repair you can adjust your way out of. The heater lists carried on this part are also not identical: the valve is named for model 53, 53A and 406A, and it is separately catalogued with Versa 55A and 55B, Versa 155A through 155C, and RP2100 R185A through R405A parts. Read the number off the valve in the heater and match it before you buy.\u003c\/p\u003e","brand":"Raypak","offers":[{"title":"Default Title","offer_id":48626603098324,"sku":"RAY-151-3569","price":273.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_5e520743-f3b6-4204-9f52-eaa69a4ef080.jpg?v=1788712951","url":"https:\/\/www.activepoolsupply.com\/products\/1-2-propane-combination-valve","provider":"Active Pool Supply","version":"1.0","type":"link"}
