We recently installed 2 model UDAP150 gas fired heaters. I am trying to set up our ISO 9001 maintenance schedule. I need to know the recommended maintenance that must be performed on these, what should be done and at what intervals.

Answer
Reznor recommends annual maintenance for their UDAS unit heaters. This should include cleaning, inspecting, and testing major components and safety devices for proper operation. Details can be found beginning page 28 of the
installation manual.
