For Propane Gas models change suffix “N” to “X”. Example: UCG-100H-199-3X (UCG-100H-399 available in Natural Gas only). All models comply with the
latest Ultra Low NOx requirements (14 ng/J or less for natural gas and 77 ppm NOx limit for liquid propane).
Amp Draw range = 1.0 to 1.8 amps.
(A) ASME - All models are available with ASME construction.
To order ASME construction add the (A) to the end of the model number.
* Based on manufacturer’s rated recovery efficiency.
For 5 year warranty models, change suffix “3” to “5”
Example: UCG-100H-199-5N
