Hi: Thanks for coming to Just Answer with your question. Perhaps I can be so some assistance, but first, let me ask you a few questions.
What kind of unit is this on? Has it been working until recently? Does any other gas appliance work? How old a unit is this? I will look forward to hearing back from you. All the best, R.J.

O.K. The first this is to be sure you have the propane pressure set correctly at the regulator. This takes a manometer. You can take it off and have a shop check it for you. Many gas problems are solved with an adjustment. If that checks out o.k. then you may have a bad thermocouple. This is what keeps the flame on after you light it. You also may have some debris in the air orofice that keeps it from having the right mix of oxygen and propane. This happens when spiders or mud-daubers get into the unit and "camp out" when you aren't using it. The theromcoulple may just not have a good connection. You can loosen it at the gas valve and then try re-tightening it. HAND tighten and then only an 1/8 of a turn. Overtightening can ruin it! You may ask any follow-up questions you feel would be helpful. Let me know what you find out. All the best, R.J.
