Model	Series	Natural Gas	Propane Gas
(A)HCG3 130T 300	100/101	1 1/4” NPT	1 1/4” NPT

This table shows connections sizes only - see Table 5 on page 13 for minimum required supply gas line sizes. Depending on the installed equivalent length, and/or the number of appliances connected, the supply gas line size may have to be increased beyond the minimum required sizes - see Gas Line Sizing on page 37.
