Emission Information
The Kohler Model CH740 engine used on the
14RCA/RCAL generator set is certified to operate using
natural gas or propane fuel.
The Kohler Model CH1000 engine used on the
20RCA/RCAL generator sets is certified to operate
using natural gas or propane fuel for emergency
standby use only. This generator set is certified by the
U.S. EPA for emergency standby operation backing up a
reliable utility source. Operation outside these
guidelines is a violation of national EPA regulations.
The Emission Compliance Period referred to on the
Emission Control or Air Index label indicates the number
of operating hours for which the engine has been shown
to meet CARB or EPA emission requirements. Figure 3
provides the engine compliance period (in hours)
associated with the category descriptor, which may be
found on the certification label.

The exhaust emission control system for the CH740
engines (14RCA/L) is EM for U.S. EPA, California, and
Europe.
The exhaust emission control system for the CH1000
engine (20RCA/L) is EM for U.S. EPA, California, and
Europe.
Generator Set Application
Kohler Co. ensures that all Kohler generator sets are
certified to applicable standards for their intended
application. It is the owner/operator’s responsibility to
operate Kohler generator sets exclusively according to
the directions provided in the accompanying operation
manuals.
Kohler generator sets designated as Stationary
Standby, Emergency or Emergency Standby may only
be operated for emergency power generation and for
maintenance/testing. Emergency power generation is
limited to power production when electric power from a
local utility (or the normal power source, if the facility
runs on its own power production) is interrupted.
Stationary non-emergency application of a Standby,
Emergency, or Emergency Standby rated generator set
is not allowed.
The U.S. Clean Air Act explicitly prohibits using
Emergency Standby generator sets as a primary
electric power source regardless of whether a site is
connected to the electrical grid. Emergency Standby
generators may NOT be used to power sites which are
not connected to an electric utility.
Owners/operators must ensure that the generator is
operated, exercised, and maintained according to this
operation manual. Owners/operators must retain
maintenance records.
