Downfiring PB 63-04 to 63-04L
I've found that the Peerless 63-04 I have is more oversized than I originally thought. I miscalculated EDR the first time around as approx. 500. After revisiting this and correcting for the tube type radiators I have, actual EDR is more like 318. If this 63-04 with output of 458 sq ft could be modified to be a 63-04L with 383 sq ft I would be alot closer to actual EDR.
Can anyone comment on what's involved to do this? The manual shows the same burner part number for a range of models - 63-03 through 64-12, but all with a different number of tubes (2 - 21 tubes). Does that mean the existing burner can be modified to 4 tubes instead of 5 or would the whole burner be replaced to do this?
