Sec. 63.25-5  Fired thermal fluid heaters.

    (a) Construction. Fired thermal fluid heaters must meet the 
requirements of part 52 of this chapter, as applicable.
    (b) Controls. Fired thermal fluid heaters must have a low fluid 
level cutout device or a low flow device. When the rate of fluid flow 
through the heating coils is insufficient to ensure proper heat 
transfer, the device must cut off the fuel supply to the burner. If the 
fluid temperature exceeds the designed maximum operating temperature, a 
high temperature limit device must cut off the fuel supply to the 
burner. These devices must be of the manual reset type.
