The 50276A (first stage propane regulator) takes tank pressure up to 250 PSI and brings it to 10 PSI. The 50274A (second stage) drops 10 PSI to 7-14 in. water column. The heater's manifold regulator then sets the final burner pressure. A propane regulator for heater applications must follow CSA B149.1 in Canada or NFPA 54 in the US.\u003c\/p\u003e\n\n\u003ch2\u003eWhich Heaters Use It\u003c\/h2\u003e\n\u003cp\u003eThis Frost Fighter 1st stage regulator fits all IDF and OHV heaters on propane.
