Installation

Proper installation is key to ensuring that your generator performs safely and reliably when you need it most. Whether you’re installing a standby generator or preparing a portable generator for emergencies, the process involves safety considerations, compliance with local building codes, and thoughtful planning.

For standby generators, installation involves securing a permanent location—typically 5–10 feet from your home—connecting the unit to your natural gas or propane line, and wiring it into your home’s electrical system via an automatic transfer switch. This allows the generator to activate automatically when a power outage occurs and shut off when grid power returns. Many municipalities require permits and inspections, so working with a licensed electrician or contractor is essential to avoid code violations or insurance issues.

Portable generator setup is simpler but still requires attention to safety. These units must be operated at least 20 feet from your home, ideally under a weatherproof enclosure with proper ventilation. You’ll need heavy-duty extension cords or a manual transfer switch to connect the generator to your appliances. Always ensure that fuel is stored safely and never backfeed electricity by plugging into wall outlets, which can endanger utility workers and your home's wiring.

On this page, we provide a step-by-step installation checklist, best practices for ventilation and placement, and tips for seasonal maintenance. You’ll also find information on surge protectors, power testing, and recommendations for hiring certified professionals. A well-installed generator isn’t just a convenience—it’s an investment in your home’s safety and resilience during blackouts, storms, or natural disasters.

Step-by-Step Generator Installation Checklist (For Standby Generators)

  1. Assess Power Needs

    • Use a wattage calculator to determine total running and starting wattage.

    • Decide if you want partial backup (essentials only) or whole-home backup.

  2. Choose Your Generator

    • Select the proper generator size (watts) and fuel type (natural gas, propane, or dual fuel).

  3. Pick the Right Location

    • Place on a flat, well-drained concrete pad or gravel base.

    • Must be at least 5 feet from doors, windows, and vents.

    • Should be within 15 feet of the electrical panel and gas line.

  4. Obtain Necessary Permits

    • Check local codes and HOA rules.

    • Apply for electrical and plumbing permits (required in most U.S. municipalities).

  5. Hire a Licensed Installer

    • A professional handles wiring, fuel hookup, and automatic transfer switch (ATS) integration.

    • Improper DIY installs can void warranties and pose fire/electrical hazards.

  6. Install Fuel Connections

    • Connect to natural gas line or secure a propane tank with regulator.

    • Test for leaks and ensure pressure meets manufacturer specs.

  7. Install Transfer Switch

    • ATS automatically switches between grid and generator power.

    • Must be wired into your home’s main breaker panel.

  8. Test the System

    • Simulate a power outage to ensure proper auto-start, power transfer, and shut-off.

    • Check voltage output and load balancing.

  9. Register Your Warranty

    • Register with the manufacturer to activate 5–10 year limited warranty (if available).

  10. Document and Label Everything

  • Keep a folder with manuals, inspection certificates, warranty, and maintenance logs.

  • Label the generator panel and circuit coverage.

Best Practices for Ventilation & Placement

Minimum Distance:

  • At least 5 ft from openings (windows/doors/vents)

  • 18 inches clearance from combustible walls or shrubs

  1. Surface:

    • Install on non-combustible pad (concrete or gravel)

    • Ensure level footing to avoid vibration and noise issues

  2. Protection from Elements:

    • Use a manufacturer-recommended enclosure or weather guard

    • Avoid installing under decks, awnings, or in flood-prone areas

  3. Exhaust Direction:

    • Point exhaust away from the house and neighbors

    • Never vent toward garages, basements, or crawlspaces

  4. Airflow:

    • Maintain 36-inch clearance around the generator for cooling air intake

    • Never block intake or exhaust louvers

Seasonal Maintenance Tips

Every Month:

  • Run for 20 minutes under load to prevent fuel gumming

  • Check for error codes or alerts on the digital control panel

Every 3 Months:

  • Inspect oil level and top off if needed

  • Check battery charge status

  • Clean around intake vents and exhaust

Every 6 Months:

  • Change the oil and oil filter

  • Inspect and replace air filters if dirty

  • Tighten electrical connections and fuel lines

Annually:

  • Replace spark plugs and fuel filters

  • Conduct full system diagnostic test

  • Flush fuel system and inspect gas regulator

  • Have a licensed technician service unit (this preserves your warranty)

After Power Outages:

  • Run a post-outage test

  • Refill fuel tanks or check utility gas line pressure

  • Log runtime hours for warranty and service tracking
