What to Avoid: Dangerous or Warranty-Voiding Modifications
While the desire to customize or "improve" a generator is understandable, some modifications are dangerous, detrimental to performance, or will void your warranty. It's crucial to understand these pitfalls.
Remote Start Kits (Third-Party): Risky Business
Generators with electric start are sometimes targets for third-party remote start kits. While convenient, these aftermarket kits are often expensive ($200-$500, plus installation) and can void your warranty unless they are specifically sanctioned or offered by the manufacturer. If remote starting is a key feature for you, consider purchasing a generator that has it built-in from the factory.
Fuel Conversion Kits: Not Worth the Risk
Converting your generator to run on alternative fuels (like propane or natural gas if it's not a dual-fuel model) using third-party kits is strongly discouraged. These modifications invariably void your warranty and emission certifications. They can also reduce performance, cause long-term engine damage, and are not recommended by manufacturers. If you want multi-fuel capability, buy a generator designed for it.
Silencers/Mufflers (Aftermarket): Performance Killer
Attempting to reduce your generator's noise by modifying its exhaust system with aftermarket silencers or mufflers can restrict or block exhaust flow. This leads to backpressure, engine overheating, reduced performance, and will void your warranty. If noise is a primary concern, invest in a quiet inverter generator from the start.
Exhaust Extensions: A Deadly Illusion
This cannot be stressed enough: Exhaust extensions are extremely dangerous and are strongly discouraged. They provide a false sense of security. Never, under any circumstances, run a generator indoors, in a garage, basement, or any enclosed or partially enclosed space. Exhaust extensions do not prevent carbon monoxide poisoning, which is an odorless, colorless gas that can be fatal in minutes. Your generator must always be operated outdoors in a well-ventilated area, at least 20 feet away from windows, doors, and vents.
