[Bill Clough]

I had a big equipment company call me today to see if I could look at thier unit. It is a MiTM stationary electric natural gas unit. The problem they are haveing is it has to be running approx.15 to 20 minutes befor the burner comes on. Anyone familure with this problem.

Need more data.

Is this a standing pilot ignition or electronic ignition?

What activates the burner, flow switch, vacuum switch, pressure switch??

 

[Bill Clough]

Mark it is a standing pilot with a flow switch

Check the gas flow to the machine, ie. inches of water column instead of pressure
