Installation
Equipment Description
This system is intended for use as an optional residential
generator system which provides an alternate source of
electric power and to serve loads such as heating,
refrigeration systems, and communication systems that,
when stopped during any power outage, could cause
discomfort, or the like. This product does not qualify for
emergency standby as defined by NFPA 70 (NEC).
This manual contains installation, startup and adjustment
instructions for a residential generator system that supplies
120/240 Volt, single phase, 60Hz devices. The generator
system may be operated on LP or natural gas fuel. A
separate Operator’s Manual (part number 202114GS)
contains operating and maintenance instructions for this

this manual is both accurate and current. However, the
manufacturer reserves the right to change, alter or otherwise
improve the system at any time without prior notice.
