Question about Nexgrill 720-0234 (LP)
Hi and welcome to FixYa. I am Kelly.
Things that cause low flames
1. LPG Tank regulator internally corroded and diaphram can not open enough to supply the correct amount of pressure. (replacement regulator required) If you do an tapping on the regulator disconnect it from the tank and if you do strike it... use WOOD! Tap from bottom and then from top.... several times. When your done... do it one more time. This may correct the problem for a short period but if it is corroded internally the problem will repeat in as little as a month.
2. The orifice holes are restricted due to spider webs insects ets. (Remove burner and Physically clean the orifice mounted on the back of the gas valve.) Worst case the orifice has to be removed and the mini orifice hole cleaned.
3. Clogged internal burner air / gas passage (remove again and clean) Use a tooth pick to clean main burner holes. Use spot tie or something long and skinny to probe into the burner air / gas passage. (Wire coat hanger works too)
4. The burner gas valves on the stem nut side are coated with grease not allowing full movement of the valve stem inside the gas valve. (remove and clean with engine degreaser)
Thanks for choosing FixYa.
