Fuel Factors
An important consideration affecting the entire installation is the type of fuel used by your Home Standby Generator. The system was factory tested and adjusted using natural gas as a fuel. Liquid propane (LP) may also be used as a fuel (see the Installation Manual).
Although there are specific factors that are inherent to each of these fuels, your location and the duration of possible utility interruptions should guide your selection of fuel type. For urban installations, Natural Gas (if available) should be your fuel of choice. For remote installations, a Liquefied Petroleum (LP) tank might better meet your needs.
For proper engine function, the following fuel guidelines are recommended:
•Use clean, dry fuel, free of moisture or any particulate material. Using fuels outside the following recommended values may cause performance problems.
In engines set up to run on propane (LP) gas, commercial grade HD5 propane with a minimum fuel energy of 2500 BTUs/ft3 with maximum propylene content of 5% and butane and heavier gas content of 2.5% and minimum propane content of 90%.
WARNING
Propane and Natural Gas is extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
•The Home Standby Generator is equipped with an automatic safety gas “fuel
•DO NOT operate the equipment if the “fuel
Power Decrease at High Altitude or High Temperature
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.
Generator Location
The actual physical location of your HSG has a direct affect on:
1.The amount of plumbing required to fuel your generator.
2.The amount of wiring required to control and connect your generator.
NOTE: Specific location guidelines are discussed in the Installation Manual. Acquaint yourself with that information and confer with your installer. Be sure to ask how your site might affect installation costs and compliance with local codes and standards.
Home Standby Generator Location
Before installing generator, consult with homeowner and convey the following guidelines which may affect the desired location.
Generator Clearances
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.
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.
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
•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.
