3‐2 Receiving & Installation MN2408
WARNING: An open bottom stationary engine generator set must be installed over noncombustible
materials and shall be located such that it prevents combustible materials from accumulating
under the generator set.
Several other factors should be carefully evaluated when selecting a location for installation:
1. For effective cooling and maintenance, the system should be mounted on a flat,
smooth, noncombustible level surface. A concrete pad is ideal and provides a secure
installation.
2. Installation should prevent water levels from reaching the generator. Drainage must be
adequate to keep concrete pad free from standing water.
3. Installation should prevent obstructions by buildup of leaves, grass, sand, snow, etc. If
these items pose a problem, consider building a small fence or other break to protect
the unit from accumulation of debris.
4. Installation should place the generator as close as possible to the fuel supply and
transfer switch.
5. At least twenty-four (24) inches clearance must be provided on all sides for air flow.
6. Access must be provided to allow the enclosure covers to be opened or removed for
service and maintenance.
7. Maximum Ambient temperature is 122F (50C).
