2-3/4U vs 2-3/4 Static Plate
A Weil McLain Gold WTGO-4 that I take care of had high stack temp and was short cycling so this year I brought it down to its lower firing rate of 1.00 vs 1.20GPH "now its a WTGO-4R". Its worked out well especially after getting the draft under control but that's another post. I was going back and double checking my work and noticed that the WM manual for the AFG burners specifies a 2-3/4 static plate for the WTGO-4 and a 2-3/4U for the WTGO-4R. So far I can find no reference differentiating the two. I assume "U" is universal. Is there really a difference?
the table is on page 5 for the curious:

It's probably the same part. If you notice, the "Air Tube Combination" number ends with "WH" for both entries. Those two letters denote the firing rate range of the air tube assembly, which is determined by the head (F4) and the plate.
The important thing is- what do the combustion test results look like?

If the fire looks good, sounds good, and all the combustion numbers are good, it is good.

Ahhh, that makes sense.
