Reducing the Risk of Fire
To help prevent fires, the generator must be installed a safe distance from all combustible materials. The unit's engine,
alternator, and exhaust system components can become very hot during operation. Reduce the likelihood of a fire by keeping
the unit properly ventilated, properly maintained, free of fuel leaks, and away from combustible materials. Also, flammable
debris may collect within or outside the generator enclosure and may possibly ignite, causing a fire.
Federal and international standards describe the minimum safe clearances around and above the generator's enclosure.
Distance Requirements
An owner must maintain minimum clearances around the generator enclosure. These clearances exist primarily for fire
prevention, but they also ensure adequate space for maintenance tasks, such as removing the unit's front and end panels.

EXPLANATION
Maintain a 3 ft (.91 m) minimum clearance from the front and ends of the generator. Keep shrubs, bushes,
plants, and trees this same minimum distance from the unit and never use vegetation to conceal the unit.
Since fuel and electrical connections occur here, keep 18 inches (45.70 cm) minimum clearance per

generator. See Protecting the Structure section in this manual.
Keep the generator at least 18 inches (457 mm) away from existing walls.
Keep removable fences at least 3 ft (.91 m) away from the front of the generator. Removable fences
include visual surrounds, fence panels, and temporary barriers without footings.
Maintain a 5 ft (1.52 m) minimum clearance from all structures, overhangs, and projections on a wall.
Allow adequate space to perform routine maintenance, such as servicing the engine and replacing the
battery. Never use shrubs, bushes, trees, or plants to conceal the generator.
