Keentel’s  8 Steps for Installing a Generac Whole-Home Standby Generator.

01

Initial Assessment & Load Calculation

• Conduct a site survey to determine power needs and the appropriate Generac generator size.
• Identify essential vs. non-essential loads if using a load-shedding ATS. Calculated By Professional Engineers 
• Verify fuel type (natural gas or propane) and availability.
• Select an installation location compliant with Generac’s clearance requirements (5 ft from openings, 3 ft from combustibles).

02

Permitting & Utility Coordination

• Obtain necessary permits from local authorities.
• Submit interconnection paperwork to the utility provider (e.g., TECO) if required.
• Schedule a gas company visit if upsizing the meter or extending the fuel line.

03

Site Preparation

• Prepare the generator pad: Use a Generac pre-cast pad or pour a concrete base.
• Ensure the pad is level and elevated to prevent flooding.
• Route conduit paths for electrical and fuel connections.

04

Installing the Automatic Transfer Switch (ATS)

• Mount the Generac Smart ATS near the main electrical panel.
• Shut off power at the main breaker before making connections.
• Run conduit and pull wires from the ATS to the generator location.
• Connect the ATS to the home's electrical system, ensuring correct phase alignment.

05

Fuel System Installation

• Install natural gas or propane lines per Generac’s BTU requirements (found in the manual).
• Verify gas pipe sizing and ensure proper regulator settings.
• Conduct a pressure test and check for leaks.
• If using propane, ensure tank placement meets NFPA 58 clearance codes.

06

Generator Electrical Connections

• Connect control wiring from the generator to the ATS.
• Connect the generator’s main power leads to the ATS.
• Properly bond and ground the generator per NEC Article 250.
• Verify correct battery installation and charge status.

07

Initial Startup & Testing

• Fill engine oil to the recommended level (Generac typically ships without oil).
• Open the gas valve and perform a prime/start sequence.
• Run Generac's self-test mode and verify proper operation.
• Conduct a simulated power outage to confirm ATS transfer functionality.
• Check for abnormal voltages, frequency, or error codes on the control panel.

08

Final Inspection & Homeowner Handover

• Schedule final inspection with the building department.
• Walk the homeowner through the generator operation, weekly self-test schedule, and maintenance intervals.
• Provide documentation, including warranty details and Generac's recommended maintenance schedule.
• Recommend annual service and remote monitoring setup (if using Mobile Link).
