Generator Set Inspection; Location And Mounting; Exhaust Requirements - Kohler 12RES Installation Manual

1.3 Generator Set Inspection

Complete a thorough inspection of the generator set.
Check for the following:
1. Inspect the generator set for loose or damaged
parts or wires. Repair or tighten any loose parts
before installation.
2. Check the engine oil. Fill, if necessary, with the
recommended viscosity and grade of oil. Use
synthetic oil, API (American Petroleum Institute)
Service Class SG or higher.
Operation Manual, for additional information.

1.4 Location and Mounting

Install the generator set outdoors near the incoming gas
service. The generator set location must allow easy
access for maintenance and service. The required
distance from a structure is dependent on state or
province and local codes. See the dimension drawing in
Section 2 for the minimum clearance from structures
and non-combustible materials.
Locate the generator set so that the hot exhaust does
not blow on plants or other combustible materials. No
plants, shrubs, or other combustible materials are
allowed within 1.2 m (4 ft.) of the exhaust end of the
generator set.
Do not install the generator set where exhaust gas could
accumulate and seep inside or be drawn into a
potentially occupied building. Furnace and other similar
intakes must be at least 3 m (10 ft.) from the exhaust
end of the generator set.
Notice
DO NOT locate the generator set near patios,
decks, play areas, or animal shelters. Keep items
such as lawn furniture, toys, sports equipment,
and all combustible materials away from the
generator set exhaust outlet.
Remind family members, children, and visitors to
use caution near the generator set. Generator
sets connected to automatic transfer switches
start automatically during exercise periods and
power outages. Some generator set components
become hot when the generator set is running and
remain hot for a time after the generator set shuts
down.
12 Section 1 Installation
The generator set is shipped on a plastic mounting pad.
Prepare a flat, level mounting area covered with a weed
barrier and gravel or a concrete pad as shown in the
generator set clearance drawing.
mounting pad directly on the gravel or concrete. Do not
install the mounting pad directly on grass.
See the dimension drawings in Section 2 for special
mounting instructions for high wind (150 MPH) areas.
1.4.1
See TP-6515,
Generator set operation. Carbon monoxide can cause
severe nausea, fainting, or death. Carbon monoxide is an
odorless, colorless, tasteless, nonirritating gas that can cause
death if inhaled for even a short time. Avoid breathing exhaust
fumes when working on or near the generator set. Never
operate the generator set inside a building. Never operate the
generator set where exhaust gas could seep inside or be
drawn into a potentially occupied building through windows, air
intake vents, or other openings.
The exhaust system is designed for generator sets
installed outdoors. Do not install this generator set
indoors.
