All fossil fuel burning equipment, such as standby

generators, contains carbon monoxide (CO) gas in the

engine exhaust. CO gas is odorless, colorless and tasteless

and is unlikely to be noticed until a person is overcome.

CO gas can kill you so it is required that the following is

included as part of the installation:

 • Installgeneratoroutdoorsinanareathatwillnot

accumulate deadly exhaust gas.

 • DONOTinstallgeneratorwhereexhaustgascould

potentially occupied building or structure.

 • BylawitisrequiredinmanystatestohaveaCarbon

Monoxide (CO) detector in operating condition in

your home. Carbon monoxide detector(s) (A) MUST

be installed and maintained indoors according to the

manufacturer’s instructions / recommendations. A CO

monitor is an electric device that detects hazardous

levels of CO. When there is a buildup of CO, the

monitor will alert the occupants by flashing visual

indicator light and alarm. Smoke alarms cannot detect

CO gas.

 • Yourneighbor(s)homemaybeexposedtotheengine

Placement of Standby Generator to REDUCE THE

RISK OF FIRE

The National Fire Protection Association (NFPA) standard

NFPA 37 establishes criteria for minimizing the hazard

of fire during the installation and operation of stationary

combustion engines. NFPA 37 limits the spacing of an

enclosed generator from openings in walls, structures, and

combustible materials outside the enclosure.

The placement requirements provided are based on

compliance to NFPA 37 2010 section 4.1.4.

WARNING

Exhaust heat/gases could ignite combustibles

or structures resulting in death, serious injury and/

or property damage.

The Gaseous Fuel System

The information below is provided to assist gaseous fuel

system technicians in planning installations. In no way

should this information be interpreted to conflict with

applicable fuel gas codes. Consult with your local fuel

supplier or Fire Marshall if questions or problems arise.

TO THE INSTALLER: Consult with the generator owner(s)

and convey any technical considerations that might

affect their installation plans before applying these

general guidelines.

The following general rules apply to gaseous fuel

system piping:

 • Thepipingshouldbeofamaterialthatconformsto

federal and local codes, rigidly mounted and protected

against vibration.

 • Pipingshouldbeprotectedfromphysicaldamage

where it passes through flower beds, shrub beds, and

other cultivated areas where damage could occur.

 • Installtheflexiblesteelfuelline(B) (supplied) between

the generator fuel inlet port (A) and rigid piping to

prevent thermal expansion or contraction from causing

excessive stress on the piping material.

 • Aunion(C) or flanged connection shall be provided

downstream to permit removal of controls.

 • Amanometerportshouldbeprovided(D). When

the initial test runs are completed, the manometer

is removed and the port is plugged. The manometer

port permits temporary installation of a manometer

to ensure that the engine receives the correct fuel

pressure to operate efficiently throughout its operating

range.

 • Wheretheformationofhydratesoriceisknownto

occur, piping should be protected against freezing. The

termination of hard piping should include a sediment

trap (F) where condensate is not likely to freeze.

 • Aminimumofoneaccessible,approvedmanualshutoff

valve (E) shall be installed in the fuel supply line within

6 ft. (180 cm) of the generator.

 • Aminimum10ft.(3m)sectionofgaspipebetween

the primary fuel regulator and the generator fuel inlet

connection (acts as accumulator for high block loads).

 • Amanualfuelshut-offvalvelocatedintheinteriorof

the building.

 • Wherelocalconditionsincludeearthquake,

tornado, unstable ground, or flood hazards, special

consideration shall be given to increase strength and

flexibility of piping supports and connections.

 • Pipingmustbeifthecorrectsizetomaintainthe

required supply pressures and volume flow under

varying generator load conditions with all gas

appliances connected to the fuel system turned on and

operating.

 • Useapipesealantorjointcompoundapprovedfor

use with NG/LPG on all threaded fittings to reduce the

possibility of leakage.

 • Installedpipingmustbeproperlypurgedandleak

tested, in accordance with applicable codes and

standards.

Fuel Pressure

Both LP vapor and natural gas fuel supply pressure at the

generator’s fuel inlet port should be between the following

levels at full load with all gas appliances turned on and

operating.

 • NGis5-7”W.C.

 • LPis11-14”W.C.

Ensure that all gas line shutoff valves are OPEN and that

adequate fuel pressure is available whenever automatic

operation is desired.

Power Loss

Air density is less at high altitudes, resulting in less available

engine power. Specifically, engine power will decrease 3.5%

for each 1,000 feet (300 meters) above sea level and 1% for

each 10° F (5.6°C) above 77°F (25°C). Make sure you and

your installer consider these factors when determining total

generator load.

WARNING Propane and Natural Gas are extremely

flammable and explosive, which could cause

burns, fire or explosion resulting in death,

serious injury and/or property damage.

• LP gas is heavier than air and will settle in low areas.

• Natural gas is lighter than air and will collect in high

areas.

• The slightest spark could ignite these fuels and cause an

explosion.

• DO NOT light a cigarette or smoke.

WARNING Propane and Natural Gas are extremely

flammable and explosive, which could cause

burns, fire or explosion resulting in death,

serious injury and/or property damage.

• Before placing the generator into service, the fuel system

lines must be properly purged and leak tested.

• No leakage is permitted.

System Connectors

Except for the power output and grounding connectors, all signal wire connections are made to removable two- or ten-pin

connector plugs. Compare this illustration with your generator to familiarize yourself with the location of these important

connections. Count down to the proper pin location on the control board since visual alignment with the decal can

bemisleading:

A - Ten-pin Connector Plug

B - Fault Contacts — Use NO, COM and NC to hook up a

siren, light, etc. to alert you in case of a fault. Contacts

reverse state (NO goes to NC and vice versa) upon a

faultcondition.

C - Transfer Switch Communication — Connect to transfer

switch control board for communication interface using

18AWG copper twisted pair wire.

D - Remote LED Output — Use this to hook up the optional

remote LED. The remote LED will turn on and off in

a series of blinks if certain faults are detected in the

generator.

E - +12 Volt DC, .5 Amp Output — Internal power supply.

F - 240 Volt Utility — Use to hook up the 240V utility leads

from the transfer switch to the generator.

G - Two-pin Connector Plug
