Before installing generator, consult with homeowner and convey the following guidelines which may affect the desired location.

Generator Clearances

WARNING

Exhaust heat/gases can ignite combustibles or structures causing a fire.

•Keep at least 5 ft. (152 cm) clearance on all sides of generator including overhead.

Place generator in a well ventilated area, which will allow for removal of deadly exhaust gas. DO NOT install generator where exhaust gas could accumulate and enter inside or be drawn into a potentially occupied building. Ensure exhaust gas is kept away from any windows, doors, ventilation intakes or other openings that can allow exhaust gas to collect in a confined area (Figure 1). Prevailing winds and air currents should be taken into consideration when positioning generator.

WARNING

Running generator gives off carbon monoxide, an odorless, colorless, poison gas.

Breathing carbon monoxide will cause nausea, fainting or death.

•Operate generator ONLY outdoors.

•Keep exhaust gas from entering a confined area through windows, doors, ventilation intakes or other openings.

General Location Guidelines

•Install the unit outdoors ONLY.

•Place the unit in a prepared location that is flat and has provisions for water drainage.

•Install the unit in a location where sump pump discharge, rain gutter down spouts, roof run-off, landscape irrigation, or water sprinklers will not flood the unit or spray the enclosure and enter any air inlet or outlet openings.

•Install the unit where the location of any services such as phone, electrical, fuel, air conditioning, irrigation, including covered, concealed and underground services will not be affected or obstructed.

•Install the unit where air inlet and outlet openings will not become obstructed by leaves, grass, snow, etc. If prevailing winds will cause blowing or drifting, you may need to construct a windbreak to protect the unit.

•Install the generator as close as possible to the Transfer Switch to reduce the length of wiring and conduit.

•Install the generator as close as possible to the fuel supply to reduce length of pipes.

IMPORTANT: Laws or local codes may regulate the distance to the fuel supply.

The Home Generator System is shipped already attached to its mounting pad. Unless mandated by local code, a concrete slab is not required.
