Install a gas supply line that runs to the unit heating
section. Refer to the NFPA 54/NFGC or equivalent code
for gas pipe sizing data. Do not use a pipe smaller than the
size specified. Size the gas supply line to allow for a
maximum pressure drop of 0.5--in wg (124 Pa) between
gas regulator source and unit gas valve connection when
unit is operating at high--fire flow rate.
The gas supply line can approach the unit in two ways:
horizontally from outside the unit (across the roof), or
through unit basepan. Observe clearance to gas line
components per Fig. 19.
