What are the installation clearance requirements for standby generators?
All standby generator clearance requierments are dicated by the National Fire Protection Association (NFPA) code 37. They must be a minmum of five feet from any openings in the walls (i.e., doors,windows, sealed windows. etc.) The minmum distance from the top of the unit is also five feet. Our air-cooled home standby generators require a minmum of 18 inches of clearance from the backside of the generator (where the electric and gas inlets are located) and a minmum of 36 inches of clearance on all other sides (intake ,exhaust and from front side). This does not apply to the 7kW CorePower TM Series. Generac liquid-cooled home standby generators, as well as CorePower Series and portable units, require a minimum of 36 inches of clearance from any non-combustible surfaces (i.e., concrete, brick, etc.) and a minimum of 60 inches from any combustible surfaces (i.e., vinyl siding , wood. etc.).
How do I size the correct gas line for my home standby generator installation?
We are not able to size the gas line for you. However, we are able to give the fuel consumption and required water column which will help the gas installers to provide the correct sizes needed for installation. These are unique to each model, consult your owner's manual for details.
Because there are so many factors that can affect gas pressure, such as having a line that is not dedicated and the distance that the line is run, your installation will require an on-site inspection and recommendation by a gas professional.
How do I set the exercise time?
For all units, 6 kW and 8-20 kW, the exercise time can be set from the control board on the "edit" screen. Simply select the date and time using the up and down arrow keys. The generator time and exercise time are in military time, so if you would like the generator to excerise at 1 PM set the exercise for 1300 hours. The CorePower TM Series/analog control boards can be set by pressing and holding the "set exercise" button for 10 seconds or until the generator starts. The unit will exercise weekly on that day and time each week. To reset the exercise, disconnect the battery and press / hold the button again at the desired day/time.
How do I calculate fuel consumption conversion?
To size a gas line for a generator, most gas companies/ plumbers will need two pieces of information -water column and BTU's. All water column/ fuel-pressure and BTU information is available in your owner's manual.
How do I activate my home standby generator?
Products with a digital control panel manufactured in 2010 or later require an activation code before the unit can be operated in automatic mode.(The unit will only run in manual mode if not activated) to get the activation code. Register the product on either generac.com or activategen.com. The confirmation page (last page of the registration ) will show the five-digit activation code at the top of the screen. For any questions or issues, calls can be transferred to our activation line (x-2832) or (888) 922-8482 (this applies to models manufactuerd in 2010 or later).
