Site Selection and Preparation
Installation Guidelines For Spark-Ignited Stationary Generators 9
Section 3: Site Selection and Preparation
Site Selection
Site selection is critical for safe generator operation. It is
important to discuss these factors with the installer when
selecting a site for generator installation:
• Carbon monoxide
• Fire prevention
• Fresh air for ventilation and cooling
• Water ingress prevention
• Proximity to utilities
• Suitable mounting surface
The following pages describe each of these factors in
detail.
NOTE: The term “structure” is used throughout this sec-
tion to describe the home or building where generator is
being installed. Illustrations depict a typical residential
home. However, instructions and recommendations pre-
sented in this section apply to all structures regardless of
type.
Carbon Monoxide
IMPORTANT NOTE: Move to fresh air immediately
and seek medical attention if you feel sick, dizzy, or
weak while the generator is running or after it stops.
Generator exhaust contains carbon monoxide (CO)—a
poisonous, potentially lethal gas that cannot be seen or
smelled. The generator must be installed in a well venti
-
lated area away from windows, doors, and openings. The
selected location should not allow exhaust gases to be
drawn into structures where people or animals may be
present.
Carbon Monoxide Detectors
See Figure 3-1. CO detectors (K) must be installed and
used to monitor for CO and to warn individuals about the
presence of CO. CO detectors must be installed and
tested in accordance with the CO detector manufac
-
turer’s instructions and warnings. Contact local building
inspection department for any applicable requirements
concerning CO detectors. See NFPA 72, National Fire
Alarm and Signaling Code, and Section R315 in the ICC
International Residential Code for more information.
IMPORTANT NOTE: Common smoke alarms do NOT
detect CO gas. Do not rely on smoke alarms to pro-
tect residents or animals from CO. The only
way to
detect CO is to have functioning CO alarms.
Asphyxiation. Running engines produce
carbon monoxide, a colorless, odorless,
poisonous gas. Carbon monoxide, if not
avoided, will result in death or serious injury.
