Location, Location, Location: A Homeowner’s Guide to Safe Generator Placement

When installing home standby generators, one of the most important factors to consider is the location where the generator will be installed on the property. There are a few basic rules that must be followed to properly install and operate a home standby generator safely.

All home standby generators should be installed no less than 3 feet away from combustible materials. Two examples of combustible materials are wood siding and vinyl siding. It is not good practice to install generators underneath decks or porches. If a generator is installed under a deck, the deck needs to be a minimum of 10 feet above the generator. These rules are put in place to prevent a generator that has caught fire from burning down the home it is backing up. It is not common for home standby generators to catch fire, but it does happen on rare occasions.

Automatic generators should always be at least 5 feet from all openings in the home. Openings in the home include, but are not limited to, doors, windows, dryer vents, foundation vents, and attic vents. This rule is extremely important because generators have internal combustion engines that produce carbon monoxide. Carbon monoxide is an odorless, colorless gas that can be deadly. If a generator is installed improperly, it may allow carbon monoxide to enter the home and cause carbon monoxide poisoning. We highly recommend installing carbon monoxide detectors in all rooms when a generator is installed within 10 feet.

Home standby generators should also be installed at least 10 feet away from propane tanks. Additionally, generators should not be installed in front of the electrical meter or any electrical panels unless they are at least 3 feet away. Other clearances that need to be maintained include 3 feet of unobstructed area all the way around the generator. This clearance allows for proper airflow and provides safe working space for technicians who maintain the unit.

These are very basic rules, and going beyond the basics is always good practice. For more information regarding the proper installation of home standby generators, please reference NFPA 37.
