SYSTEM PER APPLICABLE STANDARDS AND
_OOES. GASEOUS FUEL LINES MUST BE PROPER-
LY PURGED AND LEAK TESTED SEFORE PLACING
THE GENERATOR INTO SERVICE. NO LEAKAGE IS
PERMITTED. NATURAL GAS IS LIGHTER THAN AIR
&NO TENDS TO SETrLE IN HIGH AREAS• LP GAS
[PROPANE) IS HEAVIER THAN AIR AND SETTLES IN
LOW AREAS. EVEN THE SLIGHTEST SPARK CAN IG-
MITE THESE GASES AND CAUSE FIRE OR AN EX-
