Dual fuel generators have gained popularity due to their reliability and flexibility. Firman is among the most popular generator manufacturers in the world. They are known for their portable generators designed to provide up to 12hrs of run time. So, if you would like to back up your power system, a Firman dual fuel generator can fix your problem.

What is a Dual Fuel Generator?

If you are asking yourself, what is a dual fuel generator? Finally, we have the answer you've been looking for. A dual fuel generator uses two types of fuel simultaneously. In most cases, the fuels used are natural gas and diesel.

Due fuel generators usually start on diesel alone before switching to natural gas. This is because diesel has a lower ignition power than natural gas.

Dual fuel generators are more eco-friendly than those that solely depend on diesel. This is because natural gas burns cleaner than diesel, making the generator emit less pollution.

As already mentioned, gas burns cleaner than diesel, which lowers the routine maintenance of oil and other components.

What to Look for When Choosing a Firman Dual Fuel Generator

If you want to purchase a Firman dual fuel generator but can't decide which one, you may need some help. The good news is that we are here to offer exactly that. We shall discuss a few ways to help you choose the right Firman generator.

a). Understand Wattage

If you do not understand wattage, you will not know the power required by the generator.

i). Starting Watts

Starting watts is the momentary surge of power that a motor-driven machine requires to start. An example of such a motor-driven machine is a machine.

ii). Running Watts

This is the power your generator needs to keep running once you start it. This is not only applicable to generators but any electrical device.

b). Know Your Needs

The generator you choose should produce the total starting watts of all your devices. To get this total, use the procedure below.

i). Determine Devices

Determine how many devices you'll need to run at the same time. Make a note of the required running and additional starting watts for each device you've chosen.

ii). Add the watts

Add the running watts of all the devices you want to run simultaneously, and that's your total running watts.

iii). Determine the highest watts

The next step is to identify the device with the highest additional starting watts. Again, note the number down on paper.

iv). Calculate total watts

Add your total running watts to your highest additional starting watts to get your total running watts. This is the total starting power you'll need to run your devices.

Frequently Asked Questions About Firman Dual Generator

1. How do you power appliances using a generator?

Start your generator after plugging it into the transfer switch connection box outside your house. Manually select the items you want to power, beginning with the most important. Make sure you turn on each light or appliance one at a time to avoid overloading your generator.

2. Which is cheaper, to run a generator on propane or gasoline?

Gas is cheaper than propane; however, it doesn't make a big difference as it depends on your local prices for gas and propane. In some areas, propane costs twice the price of gasoline per kilowatt of power generated.

3. How far does a propane tank need to be from the generator?

When placing a 00-pound propane tank on your land, you need to ensure that it is at least five feet away. That is the minimum distance from any source of ignition. However, three feet is the minimum distance from the opening of a building.
