spray booth burner low burner pressure

[leiadad]

Hi, i have been called to an unusual job for our company and was looking for some guidance. The spray booth is being heated by a gas burner fed from L.P.G cylinders. The burner will come on at high heat for a few seconds and then drop to a low burner pressure. I have spoke to the customer who tells me this is not normal and should come on at high flame until temp is reached and then regulate down. I have tried linking out the stat to which the burner will then be a continuous full burner, because it done this I assumed that this temp stat was faulty and ordered a replacement. I have since been back and this replacement is doing the same thing as the original. Any help would be appreciated.
