TO SIZE PIPING:
Measure linear distance from meter outlet to last
boiler. Add total input of all boilers and divide by
1000 to obtain cu ft / hr required. Add total
equivalent length of fittings used according to
Table 6B. Align total length (pipe and fittings) on
left side column of Table 6C with highest cubic
feet of gas required.
Notes:
Consult and confirm with Applicable Fuel Gas
Code before beginning work. Verify gas inlet
pressure is between 4 and 13 in W.C. before
starting boiler.
