If you are connecting to an alternative 5 or 20lb tank instead of using the 1lb propane tanks I highly recommend it…or you it will intermittently stop working from my experience.
Mine had come with one when I got it but after a while I couldn’t get it to lite. Took it off and no problem. I only use a separate tank so I don’t know why I had problems with mine?
Confirmed via a couple youtube vids. In case you were confused like me – there are apparently 2 hose types. High and low pressure. The low pressure hose has the regulator, high pressure hose no regulator. You should only use the filter on the high pressure hose.
