We have a building with 9 Mammoth units gas fired and dx cool packaged units. The burners seem to be the most finicky burners I have ever put hands on.
It seems everytime the wind blows you have got to go and adjust the combustion air. We have had this acount for about 6 years and it has been this way pretty much every year. I have worked on them and become fairly familiar with them now and would like to know if anybody else has this problem. And if so what have you found that keeps them happy.
