Frequently Asked Questions About Gas Emergency Generators
How often should I service my gas emergency generator?
Regular maintenance is essential. Most experts recommend servicing your generator every 6–12 months, depending on usage. This helps ensure your gas emergency generator is always ready for the next blackout.
What fuel is best for a gas emergency generator?
Gasoline, diesel, propane, and natural gas are all common options. Portable generators usually run on gasoline or propane, while standby systems often use propane or natural gas. Dual-fuel models are becoming increasingly popular for flexibility.
How do I prevent carbon monoxide poisoning?
Always operate gas emergency generators outdoors, at least 20 feet away from windows, doors, and vents. Never run a generator indoors, including garages or basements. Install a battery-powered carbon monoxide detector in your home for added safety.
Do I need a transfer switch to connect my generator?
Yes. A transfer switch is highly recommended for safely connecting your gas emergency generator to your home’s electrical panel. It prevents backfeeding, which can be dangerous for utility workers and your household. Always hire a professional electrician for installation.
How long can a gas emergency generator run continuously?
Most portable gas emergency generators can run 8–12 hours on a full tank at 50% load. Some models offer longer runtimes with larger fuel tanks or dual-fuel options. Always refer to the manufacturer’s guidelines for safe operation.
Should I choose a dual-fuel or single-fuel generator?
Dual-fuel generators can run on both gasoline and propane, offering more flexibility in emergencies. Single-fuel units tend to be simpler and slightly less expensive. If you want extra backup options, dual-fuel is a smart choice.
