Ok people, I bought the smoke hollow 44 pro model, went to season it and it says to get it up to 300 couldn't get it past 256. It was 67 degrees outside. Today I tried smoking some salmon and couldn't get it past 160 but it was probably 20 to 30 degrees cooler. Tried adjusting everything and nothing worked. Looked at the flame and turned the knob to low and high again and looked like it didn't change much. I'm desperate.
It's possible that you have a bad regulator and if that's the case, contact Smoke Hollow and have them send you another one.
It's also possible that the low pressure safety function has kicked in. Turn your tank and your burners off. Disconnect the propane. Reconnect the propane making sure that the collar is threaded correctly. Turn on the propane then after 5 seconds, turn one of the burners on to High and light it. Once the first burner is going, light the second burner. Adjust the knobs between low and high and see of the flame level changes now.
