** Based on heating value
of 1000 btu per cubic foot (specific gravity of 0.6) @ 0.5
PSIG and a pressure drop of 0.3 inch water cloumn. ** Steel
pipe should be of at least standard weight (Schedule
40)
** Undiluted Liguified
Petroleum Gas @ 11 inches water column inlet pressure. Based
on a pressure drop of 0.5 inches water column. ** Copper
tubing must comply with limitations of NATIONAL FUEL GAS CODE
reference 2.6.3 metallic tubing.
Support the
piping or tubing at regular intervals with metal pipe
strapping See Chart Below:
