2 Study these SAFETY RULES carefully before installing, operating or ser vicing this equipment. Become familiar with this manual and with the unit. The generator can operate safely , efficiently and reli- ably only if it is properly installed, operated and maintained. Many accidents are caused by failing to follow simple and fundamental r ules or p[...]

3 Adequate, unobstr ucted flow of cooling and ventilating air • is critical for expelling toxic carbon monoxide gas and fuel vapors from the generator compar tment and for proper genera- tor operation. Without sufficient cooling air flow , deadly carbon monoxide gas can accumulate and the engine/generator may quickly overheat, causing serious dam[...]

29 2.5.3 VAPOR WITHDRAWAL  LP gas is stored in pressure tanks as a liquid. The gas systems used with these generators were designed only for vapor with- drawal type systems. V apor withdrawal systems use the gas vapors that form above the liquid fuel in the tank. Do NOT attempt to use the generator with any liquid withdrawal type system. 2.5.4 P[...]

30 D ANGER  Gaseous fuel lines between the tank and the secondary regulator are under a positive pres- sure (about 11 inches water column). Gas pres- sure at the outlet side of the secondary regula- tor , however , is a negative pressure and can draw flame inside a line or fitting and cause an explosion. 2.6 EXHA UST SYSTEM The generator exhaust[...]

31 Never tee • the generator engine exhaust pipe into the vehicle engine exhaust piping. This causes excessive back pressure on the generator engine. Also, water from one engine can damage the other engine. Plan exhaust system installation carefully . Comply with all appli- • cable codes, standards and regulations. 2.7 ELECTRICAL CONNECTIONS Be[...]
