User questions & answers

Question: Can it replace
Answer: So without looking up the numbers, which is what you need to do as there is information out there, I can tell you I bought this as a correct replacement for mine. The gas line does come into it differently and needs to be reconfigured, and it comes with a different orifice for your burner, which you have to research to determine the correct size. I ended up returning this as it was just too much of a hassle to replace. What I did was replaced my burner, which was easy. Then I had the same problem with my heater shutting down with a fault code, so I realized if I push straight in on my gas valve, it stayed lit. I then put 2 zip ties around the valve, one vertically, and one horizontally. It works like new now, and saved buying a new heater! I hope this helps.
