3. Step-By-Step Outline of Installation 1-2014
3.2 Generator Set Installation Requirements
WARNING
EXHAUST GAS IS DEADLY! Install the generator set out-doors only. The generator set
must be located away from doors, windows and other openings to the house and where
exhaust gases will disperse away from the house.
Generator set location is critical for safety and performance. Follow the guidelines below
• Must comply with applicable codes (NFPA, NEC, etc.).
• Install out-doors only.
• Call the local utilities to mark the locations of buried utility services (gas, electric or
telephone) before digging trenches for fuel and electrical lines.
• Ask the homeowner for locations of any other buried components (gas, electric or
telephone) before digging trenches for fuel and electrical lines.
Clearances:
• The exhaust side of the generator set must be located 5 feet from combustible materials
(NFPA 37).
• The exhaust side of the generator must be located 5 feet from any opening in a wall
(window, door, vent, etc.).
• The generator must be located such that the exhaust is not able to accumulate in an
occupied area.
• The generator must have access for installation, service and maintenance as deemed
appropriate by a Cummins Power Generation authorized dealer or installer.
• The generator must be located to ensure ventilation openings are not blocked.
3.3 Generator Set Installation Suggestions/Guidelines
• Locate the generator set on stable ground, not subject to flooding.
• Locate and orient the generator set such that prevailing winds will carry exhaust gases and
fuel leaks away from the house or occupied area.
• Make sure engine vent port on the side of the enclosure is not blocked and is free of
debris.
3.4 Preparing the Site
Steps to preparing a proper/safe generator set site:
1. Create a level area.
Add a layer of sand or pea gravel that is deep enough that the generator set will sit level.
2. Be sure that the area is at least 48 in by 34 in (1219 mm by 864 mm).
Sites on an incline require more area.
3. Be sure that the area is on firm ground.
