Home Standby Generators and Snowstorm Preparedness

What do I do when I expect a snow storm, or if there is snow building up around the unit?

Before the snowstorm:

Clear Surroundings: Clear snow and ice from the top of and around the generator enclosure. Accumulating snow and ice may affect the generator's operation or cause damage to the generator by restricting airflow to the exhaust system. Maintain at least a 3 foot clearance around the unit to guarantee proper airflow during operation.

Wind Protection: If blowing or drifting snow is a concern due to prevailing winds consider installing a windbreak at a safe distance to shield the unit.

Preparation for Absence: If you expect to be away during potential snowstorms, arrange for a trusted neighbor or family member to monitor the generator. Alternatively, you can turn the unit off and remove the 7.5 Amp fuse in the generator's control panel to prevent operation. (For extended off periods of more than 90 days, follow the "remove from service' procedures detailed in the owner's manual.)

Enclosures: Generac’s generators are not designed or intended to be enclosed in a secondary enclosure. Generac’s home standby generators include an all-weather housing with venting designed and tested to provide proper airflow and exhaust for the engine in open air.

During snow accumulation:

Airflow Maintenance: Regularly check and clear the intake and exhaust areas of the generator to prevent snow and ice build. Snow and ice can restrict airflow and cause operational failures.

Air Filter Management: In conditions where blowing snow can fill the airbag with ice and snow, it's crucial to keep the air filter area clean. Although not a defect, such conditions can affect generator performance. Remove the air filter, clean out the airbox, and allow the filter to dry indoors.

Ice Removal: In case of ice storms many operational issues can be resolved by simply removing ice from the generator's intakes and exhaust. Ensure the air filter is not frozen and maintain it clean and dry.
