Burnham V-73-T tankless coil size help
I need to replace leaky tankless coil in my Burnham V-73-T boiler. What size coil should I use? 5GPM? Would 6 GPM coil fit? I have a rectangular plate 5x12-1/4 with 8 bolts. The boiler is 105000 BTUs. The current marking on the tankless plate says V1-2. I called multiple plumbing stores and suppliers, but no one can tell me if 6 GPM coil will fit. Are there any spec sheets with measurements available? I also can't find anywhere how large the coil compartment is. The boiler manual has all dimensions, but no diagram for the coil compartment. So, will either 5 or 6 GPM coil fit? Is there a reason to choose 6 over 5?
