GAS PIPING
Install the gas piping according to all
local codes and regulations of the utili-
ty company.
If possible, run a separate gas supply
line directly from the meter to the fur-
nace. Consult the local gas company
for the location of the manual main
shut-off valve. The gas line and man-
ual gas valve must be adequate in
size to prevent undue pressure drop
and never smaller than the pipe size
