While Generac's Guardian Series automatic standby generators can operate continuously, they will need to be stopped at least once every 24 hours of continuous operation to check on the unit and provide any maintenance that may be required at that time. After these tasks have been performed, the unit can be restarted for continued operation.

We are sorry to learn of the issues that you are currently experiencing with your automatic standby generator. Please note that an Overcrank alarm will occur if/when the engine has not started within the specified crank cycle. This is defined as any of the following occurrences during cranking: 1. Not reaching starter dropout within the specified crank cycle. Starter dropout is defined as four (4) cycles at 1,000 RPM. 2. Reaching starter dropout, but then not reaching 2200 RPM within 15 seconds. In this case the control board will go into a rest cycle for seven (7) seconds, then continue the rest of the crank cycle. If you continue to experience this alarm, we recommend contacting your gas line installer first, as ensuring correct fuel pressure is the first step in the troubleshooting process, and if applicable, would fall under improper installation under the warranty statement.

The Quiet-Test™ Mode is utilized during the unit's exercise period. We assure you that we would not offer a feature that is not recommended. Perhaps most importantly, we wish to acknowledge the fact that the exercise mode is not meant to warm the generator; it is designed to perform a weekly test to ensure the unit is prepared to operate when you need it most. If extremely cold temperatures are of concern, we would then recommend considering the use of a cold weather kit, which helps to keep the unit's battery and crankcase warm during cold weather months.

The exercise time for newer units can be set for five (5) minutes. If your unit is exercising for this period of time, a change has likely been implemented via your unit's control panel. If such a change has been made, an asterisk will appear in the corner of the unit's control panel display. Moreover, as this change can only be implemented by an independent authorized dealer, we would recommend contacting the company that last serviced your unit to inquire about any changes that may have been made during the servicing of your unit. If you have any other comments, questions, or concerns, please do not hesitate to contact us directly at 888-GENERAC (436-3722).

If your oil is low, we would recommend refilling it as needed. If you would like to check whether or not your unit has exercised in the last week, we would recommend using the unit's control panel to check the product's run log. If you are unfamiliar with navigating your unit's controller, we would recommend following the Menu Map provided in the unit's owner's manual. If you still need help after referring to this documentation, please do not hesitate to contact us directly at 888-GENERAC (436-3722).

Question

Generac 5-year Extended Warranty

I am just reading about the Generac 5-year Extended Warranty for my standby generator.

It is stated as follows:

Proper maintenance is essential to ensure reliable operation of your generator. Scheduled
maintenance, as outlined by the generator owner's manual, is highly recommended. Scheduled
maintenance should be performed by an Authorized Generac dealer, or a branch thereof. This
will verify that service has been performed on the unit throughout the warranty period. Your
generator must be registered and Proof of Purchase and Maintenance must be provided at the
time a warranty claim is filed.

Can you please tell me what is considered Proof of Maintenance ?
Is it receipts for oil/air filter etc. and documentation ?

Part of the process for making a warranty claim requires proof of maintenance. This can be done by providing receipts for the items used to maintain your unit, along with a log or alternative documentation that shows what maintenance-related tasks were completed and when; this could be a calendar with associated dates, or a spreadsheet that specifies dates and services provided. If you have any other questions, please do not hesitate to contact us directly at 888-GENERAC (436-3722). We hope you find this information to be helpful.

If you are having issues removing the battery from its assigned compartment within your automatic standby generator, we would recommend either removing the bolt located at the bottom of the unit’s dividing panel/heat shield, just to the left of the unit’s battery (this will free-up space to slide the battery out of the compartment), or contacting an independent authorized service provider in your local area for assistance.

Question

Fuel Consumption at Less than Half Load?

I'm looking to install a backup generator for my vacation house. Peak loads are likely to be in the 15-18kW range, but average loads are likely to be in the 2-4kW range if we are there, and lower if we aren't. Extended (4-6 days) power outages aren't uncommon for this area, and it is possible that the house would be unoccupied during a power outage. Fuel consumption and how long the house would be backed up in a power outage are a consideration. The Guardian 20kW or 22kW units appear to fit the load requirements, but the spec sheet only provides fuel (propane) consumption data for half and full load; is there any information available for lower loads?

The 25KW unit spec sheet provides fuel consumption for quarter load, however it is quoted as having quite a bit higher fuel consumption compared to the other two units, so likely isn't an option.

As you have alluded, we provide fuel consumption ratings for air-cooled units operating at 50% and full load. Unfortunately, we do not test our unit's for fuel consumption rates at alternative load levels, as the fuel line supply should only be sized for operation at full load.

Whenever the unit is serviced or the battery is removed, the exercise time will need to be reset via the unit's control panel. If you have already performed this step and the run log does not show that the unit has been exercising, we would then recommend referring to the unit's control panel to ensure that an error code/active alarm is not present. If an error code is displayed, or if your unit is still unable to exercise after ensuring the exercise time has been set, we would then recommend contacting an independent authorized service provider in your local area for any diagnostic or servicing work that might be required.

We do not recommend installing the unit in any type of enclosed area. Per the NFPA 37, all air-cooled generators feature the following minimum clearance requirements: the unit should be placed 5 feet from any wall opening (i.e. door, window, etc.) and the front of the unit, along with the two ventilating sides should be placed 3 feet from any surface or structure. However, the back of the unit can be placed as close as 18” from any surface or structure. Also, please note that these recommended clearance requirements are superseded by local codes. We would recommend working with your local inspector, to ensure that your unit is installed properly in accordance with any local ordinances that may apply to your desired configuration.

The only time precipitation will affect the generator is if flooding occurs and water begins to fill the unit's interior, or if snow is allowed to accumulate around the unit, which would inhibit the unit's ability to ventilate properly. Considering this, we recommend working with an independent authorized dealer in your local area to ensure that you are installing the unit away from a flood zone in accordance with any local codes that may apply. To locate an independent authorized dealer closest to you, please use your postal code for searching purposes here: http://www.generac.com/dealer-locat... . Lastly, there should be no snow piles or large accumulations of snow within five feet of the unit; this is to help ensure proper air flow is provided to the unit if/when it is needed during a utility outage. If snow builds up, we would recommend clearing it off of and away from the generator. If you have any other product-related inquiries, please contact us directly at 888-GENERAC (436-3722).
