INSTALLATION

GENERATOR CLEARANCES

These units should be mounted a minimum of 24” from 

a structure. This will allow for ample room to maintain 

and work on the generator set. Units must be installed in 

accordance with all local, state, and national codes. Consult 

your local agency for specific requirements.

DANGER: DEADLY EXHAUST GAS

Carbon monoxide (CO) is an orderless, deadly gas. Keep 

genset exhaust a minimum of 60 inches away from vents, 

windows, doors, soffit, and other openings to the building. 

Check with local codes for more information about 

generator clearances. Failure to safely install your genset 

can result in serious personal injury and/or death.

ENGINE-GENERATOR SET MOUNTING

WARNING

Before proceeding with installation, be sure the operation 

selector switch is in the stop position. 

These engine generator sets are designed to be mounted 

on a pad outdoors only. The transfer switch is mounted 

next to your electrical entrance or distribution panel 

inside or outside the building. Consult a qualified, licensed 

electrician or contractor to install and wire the transfer 

switch. The installation must comply with all national, state 

and local codes. Before beginning the installation process 

check the rating of the generator set and its transfer 

switch rating. Be certain they can handle the intended 

load and are compatible with the entrance voltage, 

phase and current ratings. Plans for installation should 

be prepared with proper attention to mechanical and 

electrical engineering detail to assure a satisfactory system 

installation. The information in this manual is offered only as 

a guide to finalizing your installation plans.

WARNING: PERSONAL INJURY

The enclosures on these units can become very hot 

adjacent to the exhaust areas. Special care must be taken 

when installing these units to insure that the risk of contact 

by people is minimized.

The unit’s main frame should be bolted to a pad that meets 

local code. Various materials, including concrete and 

composites, are acceptable as long as they are structurally 

sound supporting the weight of the unit and preventing 

movement during operation. The mounting holes on the 

base of this unit is 0.563” in diameter. The engine-generator 

is mounted on a sub-frame which is isolated with special 

shock mounts on the main frame. This allows the engine-

generator to vibrate without affecting the control panel on 

the main frame.

Do not install any shock mounts between the base frame 

and the pad. Engine vibration will be transmitted to the 

control panel causing erroneous start/stop cycles and 

premature control failure. 

FUEL INSTALLATION

The fuel supply should be as close as possible to the 

engine. This will reduce the installation cost of fuel runs. 

The information in this manual is offered to assist you in 

providing the proper fuel for your engine. However, this 

information is only provided to inform you of the engine’s 

requirements and assist in making you aware of the 

decisions you must make. In no case should the instructions 

and information provided be interpreted to conflict with 

any local, state or national codes. If in doubt, always consult 

your local fire marshal, gas supplier or building inspector.

WARNING: FIRE HAZARD

All fuel runs should be installed by a licensed fuel supplier.
