BRUTE ELITE
NATURAL GAS
REQUIRED		TO SIZE PIPING:
CU FT
SIZE	/ HR.	Measure linear distance from meter outlet to last
80	80	boiler. Add total input of all boilers and divide by
		1000 to obtain cu ft / hr required. Add total
105	105
		equivalent length of fittings used according to
150	150
		Table 6B. Align total length (pipe and fittings) on
199/210 199/210		left side column of Table 6C with highest cubic
285	285	feet of gas required.
399	399	Notes:
500	500
		Consult and confirm with Applicable Fuel Gas
600	600	Code before beginning work. Verify gas inlet
750	750	pressure is between 4 and 13 in W.C. before
		starting boiler.
