ULN Furnaces – Product Overview (4 of 8)

Pat Burke continues with his Ultra Low NOx class and introduces everyone to the four available models – 59SU5, 58SU0, 59CU5 and 58CU0. Because the furnaces are only used in a few regions of California, it’s a very limited product offering, so be sure to know the details about what is available and what isn’t available.
