Yes, a one-inch hose should enough. People I know have used a 3/8″ airline and a 5/8″ garden hose (no joke) to run natural gas to a generator temporarily.
For a natural gas generator, what size hose do you need?
Though a generator may require 3/4 or larger tubing to connect to it, if kept short, a 1/2 hook-up hose is usually sufficient. We recommend that you contact your local gas provider or a certified plumber for assistance.
A 22kw Generac generator requires what size gas line?
NOTE: The gas supply and pipe must both be rated at 100 percent load BTU/megajoule. NOTE: Units rated at 8-16 kW need a 1/2 in connector. A 3/4 in connection is used for 20-22 kW units.
Is it possible to connect a generator to a natural gas line?
Once you’ve determined that your portable generator can handle the fuel, connecting it to a natural gas connection is rather simple. Before connecting your generator to the natural gas mains, you’ll need to install a carburetor and conversion kit if it operates on liquid fuel like gasoline.
There’s more to know about natural gas and portable generators. Natural gas generators and the many techniques to connect a portable generator to natural gas are discussed in this article. It also offers information on how to connect to a natural gas supply if desired, as well as the benefits and drawbacks of using natural gas to power portable generators.
What is the fuel consumption of a natural gas generator?
It’s vital to keep in mind that the cost of running a generator varies depending on the power demand, and many modern generators have low-fuel or half-load modes. The estimated expenses of running your generator could be reduced or increased depending on these variables.
Gasoline Generator
Portable generators are most commonly powered by gasoline. A typical 5-kilowatt generator uses roughly 0.75 gallon of gasoline every hour. In July 2018, the average price of gasoline in the United States was $2.89 a gallon. If you used the portable generator for a day, it would use roughly 18 gallons of gas, which would cost around $52 per day to run. Because gas prices change, running these types of portable generators for an extended period of time can be costly.
Diesel
Portable diesel generators are less prevalent, although their fuel costs fluctuate like gasoline’s. Diesel costs roughly $3.17 per gallon on average. When running at full capacity, a 20-kilowatt generator will consume around 1.6 gallons of gasoline every hour. As a rough estimate, the cost of running the generator for a day would be $122.
Propane Generator
In the portable generator market, propane generators are frequently the cleaner energy alternative. Propane, on the other hand, burns more fast in a generator. A 20-kilowatt generator would consume around 3.45 gallons of gasoline each hour. As of March 2018, the average price per gallon for propane in the United States was roughly $2.50. A portable generator would use roughly 83 gallons of gas and cost over $200 to run for 24 hours.
Some standby home generators use propane, which is stored in big tanks on-site, which helps to reduce expenses by requiring fuel to be purchased in bulk less frequently. Under full load, a 22-kilowatt generator for the residence will burn around 3.6 gallons per hour. The standby generator costs the same as the portable version to run, a little more than $200 each day.
Natural Gas Generator
Because many homes are already supplied with natural gas, natural gas is quickly becoming the preferred fuel for residential standby generators. Natural gas costs $3.25 per thousand cubic feet in the United States right now. Because a 7-kilowatt generator uses around 118 cubic feet per hour, the cost of operation is only $0.82. Operating costs for a larger 15-kilowatt unit rise to $1.71 per hour, utilizing 245 cubic feet of natural gas.
This indicates that running a generator for the 10-minute “workout period” once a week would cost roughly $4 to $5 each month. And, depending on the energy load, the generator will spend roughly $20 to $40 every day during a power outage.
What is the maximum time a natural gas generator can run continuously?
A backup generator can power a medium-sized home for up to 3,000 hours on average, while it is not suggested to run a generator for more than 500 hours continuously.
Question: how to solve fuel-starved electric generator: regulators “fighting” for fuel
A 500-gallon liquid propane tank powers a 25,000 Btu space heater and a 20 kVA standby generator.
A regulator exits the propane tank, and a regulator provides the stove and generator from the split.
When the generator is functioning in the event of a power loss, it frequently “surges,” causing the lights to flicker, which is bad for motors and electronics.
I’ve noticed the two regulators “fighting” on multiple times, and I learnt in school that you can’t install two pressure controllers next to each other and expect either to work.
Is there a way to manage the pressure between the tank and the second (home) regulator with orifice plates such that the required pressure is maintained at the upstream side of the house regulator with a “control action”?

Reply: how to fix gas regulator surging / fighting for your 20kW backup electric generator
Your gas supplier should provide an authoritative response, as I’m not sure what the best solution is.
However, I believe the regulators are not properly installed, the pressures are incorrectly set, or the gas pipe is too small. An LPG tank that is too small is less common. (A common minimum size is 250 gallons.)
Check the gas regulator size, capacity, and location
Both primary and secondary regulators should be checked for location (and, of course, presence).
A first-stage gas pressure regulator is often put at the tank (or at the gas meter if using natural gas), and a second regulator is typically installed at or even inside each gas appliance.
In most cases, backup electrical generators necessitate the purchase and installation of a separate primary or first stage gas pressure regulator. The generator does not come with one.
The backup generator, on the other hand, will almost always come with its own second-stage gas regulator. You may need to set or change the regulator to the correct fuel type: NG (natural gas) or LPG (liquefied petroleum gas) (propane).
However, the position of that second-stage regulator should be found in your generator’s instructions.
Your plumber will need to compare the primary stage regulator’s delivery capability to the entire possible LPG demand.
A 20kW Generac electric generator will utilize 3.85 gallons of LPG or 14.57 liters of LPG per hour at a flow rate of
The location of the generator will also effect the needed pipe diameter, as shown in our gas piping distance figures below.
Check the gas piping diameter, length, elbows vs generator size & fuel type
It’s also possible that the gas piping’s diameter is too small for the desired flow rate or the distance the fuel must travel.
The gas supply and pipe must be sized at 100 percent load BTU / megajoule rating to avoid the problem you describe. According to what I’ve read, one of the most typical mistakes committed in LPG generator installation is using undersized gas supply piping.
- The pipe for a 20kVA gas-fueled GeneracTM electric generator is normally 3/4″ ID (interior diameter).
- In the 8-16kW range, GeneracTM generators commonly employ 1/2″ ID piping.
You’ll probably find a table in the installation manual for your generator that lists the maximum total distance of piping that can be used for various pipe diameters. You’d have to factor in the number of bends, elbows, and limits as well.
Is it possible to utilize a propane hose with natural gas?
Natural gas or propane are used to power many heaters and appliances.
Natural gas is a mixture of gases that can be found underground, including butane, propane, and methane. It can exist as a liquid, a compressed or uncompressed gas, or both.
Propane gas, commonly known as liquefied petroleum gas or LPG, is extracted from natural gas and stored as a liquid.
Appliances that run on natural gas or propane are available for use in the house. The two cannot be used interchangeably; each fuel source necessitates the use of unique gas usage fittings. You’ll need a conversion kit from the appliance’s maker for the installation process if you want to move between the two. There is no conversion process for electric equipment such as heaters, ovens, or water heaters; instead, you must replace the device with one that is expressly designed for natural gas or propane.
Natural gas is a utility that is only available in particular places, with subterranean pipelines transporting the gas into the residence. Propane is stored in tanks that must be refilled and replaced on a regular basis. Some containers are small enough to be carried around, while others are huge enough to be buried underground. Burying a tank is similar to connecting your home to a natural gas pipeline.
You’ll need to get rid of your propane tank or have it emptied and left in place if you transition from propane to natural gas or stop using propane and switch to electric appliances. It’s difficult to get it out of the ground, but once you’ve done so, you can sell it to someone else.
Propane has the advantage of being able to be transported to any location. Natural gas is subject to pipeline availability and whether it is available in your area. Installation and refilling of propane are both dependent on delivery. After a big storm or another disaster, you can run out of gas. Natural gas is constantly available because it is connected by pipelines.
Propane is normally more expensive than natural gas, but it delivers almost twice as much heat in the same amount. The cost of using one over the other is heavily influenced by where you live. In many areas, though, both types are more efficient and less expensive than electricity. Installing a new natural gas line can be costly, but the investment could save you money in the long run.
Your decision to upgrade may be influenced by the appliances you already own. A furnace, whether it runs on natural gas, propane, or electricity, has a lifespan of roughly twenty years. Electric ranges have a fifteen-year lifespan. However, if you’re remodeling and replacing your home’s appliances, now can be a good time to improve your fuel system as well.
The gases natural gas and propane are both colorless and odorless. Manufacturers add a nontoxic chemical called mercaptan to give it the unique odor of rotten eggs or sulfur to aid detect gas leaks. Put out any flames and go outside if you notice a scent in your home. Then dial 911 and wait for emergency personnel to arrive to check that your home is secure.
A Generac 22kw generator consumes how much natural gas?
The amount of fuel consumed and how rapidly it is spent is determined by the generator’s size as well as the load it is supporting. Fortunately, a Generac expert can help you choose the correct size generator based on your home’s square footage, whether you want to power the entire house or just select systems or appliances, and how long you intend to operate your generator.
A 22 KW Generac generator, for example, will consume 9.7 cubic meters of natural gas while operating at full load. You will be able to keep your home up and running for an unlimited period of time if it is directly connected to your natural gas lines.
Another example: a propane generator may use roughly 2-3 gallons per hour, depending on what you’re powering and the size of your generator (let’s assume 20kw in this case). So, if you have a 500-gallon tank that can only hold 400 gallons of water, a full tank will last you 6 to 7 days. Again, these are merely estimations, and a true estimate of generator fuel consumption rates would need to be provided by a Generac professional after taking into account what you plan to power and the type of fuel you intend to use.
Is it possible for me to install a Generac generator myself?
Generac offers pre-packaged and pre-wired Guardian Series systems with detailed installation instructions as an option. You can either do the basic site preparation stages yourself and have a professional connect the electrical panel and fuel lines, or you can do everything yourself.
