I am in the process of making modifications to our gas fired hot oil heater and am trying to find the applicable codes. I was given NFPA 8502, which covers multiple burner boilers, but, it states that process heaters are not covered by the standard.
"1-1.4 Furnaces such as those of process heaters used in chemical and petroleum manufacture, wherein steam generation is incidental to the operation of a processing system, are not cov-ered
by this standard."
