Based on this testing and the requirements of NFPA 37, Sec 4.1.4, the guidelines for installation of the genera-
tors listed above are changed to 18 inches (457 mm) from any point of the generator enclosure to a stationary
wall, building or structure. The required distance for maintenance and airflow clearance, the area above the genera-
tor should be at least 5 feet (1.52 m) with a minimum of 3 feet (0.91 m) at the front and ends of the enclosure. This
would include trees, shrubs and bushes. Vegetation not in compliance with these clearance parameters could obstruct
air flow. In addition, exhaust fumes from the generator could inhibit plant growth. For details, see the installation draw-
ing within the owner's manual and Figure 3-1.
Generator exhaust contains DEADLY carbon monoxide gas, which can cause unconsciousness or death. Do not place
the unit near windows, doors, fresh air intakes (furnaces, etc.) or any openings in the building or structure, including
windows and doors of attached garage.
*
If the generator is not set to the OFF mode, it can crank and start as soon as the battery
cables are connected. If the utility power supply is not turned off, sparking can occur at the
battery posts and cause an explosion.
3.2 — Site Preparation
Locate the mounting area as close as possible to the transfer switch and fuel supply.
•
• Leave adequate room around the area for service access (check local code), and place high enough to keep out
rising water.
• Choose an open space that provides adequate and unobstructed airflow.
Position the unit so air vents will not become clogged with leaves, grass, snow, or debris. Be sure exhaust fumes
•
will not enter the building through eaves, windows, ventilation fans or other air intakes (see the "Site Selection"
section).
• Select a gravel or concrete base depending upon local code requirements.
