Connecting the Gas Supply Line to the
Furnace Gas Train
Follow the steps below to complete the installation
between the supply gas line and the furnace. Refer to
the following figures, for the appropriate gas train
configuration.
1. Connect the supply gas piping using a “ground-
joint” type union to the furnace gas train and check
for leaks.
2. Adjust the inlet supply pressure to the
recommended 7" to 14" w.c. parameter for natural
gas (11" to 14" w.c. for propane).
3. Ensure that the piping is adequately supported to
avoid gas train stress.
