Do I need the automatic transfer switch in order for the generator to exercise itself?
John A. 
from Missouri 
December 21, 2016
Answer
A Generac automatic transfer switch is needed in order for the unit to exercise and run. This is due to the control wiring that is needed from the switch to the generator.

Is there a cold weather kit for this?
Joe B. 
from Oklahoma 
December 20, 2016
Answer
Below is a link to the three items for the cold weather kit. The breather heater is not needed unless you are in a very cold climate such as Montana or Northern Minnesota.
Generac 9-22kW Air Cooled Battery Heater Kit
Generac 9-22kW Air Cooled Oil Heater Kit

Do I need to add a pressure regulator for the gas or does the unit have one already?
Joe M. 
from Texas 
December 18, 2016
Answer
The regulatoráincluded in these units is intended to fine-tune the pressure entering the engine. A primary regulator may need to be supplied in the field if gas pressure entering the unit is too high. Generac requires a pressure of 3.5"-7" w.c. for Natural Gas andá 10"-12" w.c. for Propane.á This would have to be determined by a local plumber and/or gas company. Furtherádetails can be found on pageá17 of theáinstallation manual.

How do you properly size a generator for a 1500 sq. ft. to 2000 sq. ft. home?
Kenneth F. 
from Arkansas 
December 13, 2016
Answer
Properly sizing the generator is crucial to the success of any generator installation and requires a good working knowledge of electricity and its characteristics, as well as the varying requirements of the electrical equipment comprising the load. A certified electrician needs to be consulted for proper sizing and installation of any generator. When analyzing the electrical load, consult the manufacturerĺs nameplate on each major appliance or piece of equipment to determine its starting requirements in terms of amps and voltage which can be calculated to watts using Ohms Law (Amps x Volts = Watts). When choosing the generator output select a rating that is approximately 20 to 25% higher than the peak load (for example, if the load is about 8 kilowatts, select a 10 kW generator). A higher rated generator will operate comfortably at approximately 80% of its full capacity and will provide a margin of flexibility if the load increases in the future. Note: Applications that are commercial, all-electric homes, have heat pump systems or geothermal systems require special installation procedures and a certified electrician must be contacted to evaluate and install these types of systems.
