2. Setup

Proper installation is crucial for the safe and efficient operation of your Generac Guardian generator. Generac strongly recommends that your new Home Standby Generator be installed by a certified and licensed electrician or qualified service technician.

2.1 Site Preparation

• Location: Ensure the generator is placed on a stable, level surface, away from windows, doors, and vents to prevent exhaust fumes from entering the building.
• Base Pad: A concrete pad is recommended for stability and to ensure proper ground preparation.

2.2 Fuel Connection

The Generac Guardian 10kW generator operates on either natural gas (NG) or liquid propane (LP) gas. The unit must be connected to your home's existing fuel supply by a qualified professional.

2.3 Electrical Connection

The generator includes a 100 Amp 16-circuit transfer switch for seamless integration with your home's electrical system. This transfer switch ensures automatic power transfer during outages. All electrical connections must be performed by a licensed electrician.

2.4 Battery and Accessories

A battery is required for the generator's electric start function but is not included with the unit. If you reside in a cold climate, consider purchasing a cold weather kit, which typically includes a battery warmer and oil filter warmer, to ensure reliable operation during winter months.
