Q: I am interested in the 8kw natural gas Generac generator. I have a gas furnace and a fire place - gas log; Will I need a dedicated gas pipe line for my Generac generator or can I tap off existing t in basement?
by Tom Shea from Massachusetts on April 24, 2013

A: Manufacturer recommends a dedicated fuel line to the generator which helps prevent running issues. 90% of all generator problems are caused by fuel issues and improper installation.

by Jim, Product Expert
Q: Jim, I am awaiting delivery of the 5870 and would like to know what size concrete slab you recommend
by Thomas Gould from New York on January 14, 2013

A: The minimum thickness is 3 - 4 inches thick and the dimensions can be found in the installation drawing on the website under the specs link on the generator model page....

Q: Can the 100amp transfer switch that comes with model #5870, be mounted in a weatherproof enclosure for outside installation, which is where my main distribution panel is located.

Thanks,
Ervin

by Ervin Rathbone from North Carolina on January 14, 2013

A: Yes, as long as you change the wiring cover to a weather proof covering and change the connections so no water can get into the switch. This will need to pass your local codes and inspector.

Note: You may lose your UL rating on the switch as this was tested for indoor installation only.

by Jim, Product Expert
Q: If the distance from the transfer switch to the generator far exceeds the 32 ft. prepackaged configuration, would I order a prepackaged unit then eliminate the 32' shielded cable and replace with my own? What is the gauge of the power wires in the 32' cable?
by Dan Vecchio from New Jersey on December 22, 2012

A: The indoor run from the switch to the wall where you go out to the generator is 30 feet and the run from the switch to your electrical panel is 2 feet. The generator also has an outdoor run of 5 feet connected to the back of the generator along with an outdoor connection box to connect the 30 foot length to where you penetrate the wall.

Per Generac you can add an additional maximum of 15 feet to any of the 3 lengths if needed.

The control wires are 14 gauge, the 2 hots and neutral are #6 and the ground is #8.

by Jim, Product Expert
Q: How often does Generac suggest servicing an 8kw essential circuit? How long before oil should be changed?
by Bryan Sullivan from New Jersey on December 21, 2012

A: According to the manual it would be every 2 years or 200 hours, whichever comes first.

Q: Hi can this 8kw can be used with electronic equipment . Generac Guardian 8kw standby generator system ( 100A 10 circuit switch)
by Emil Scharer from New York on December 08, 2012

A: Yes, this system does offer Generac's TruePower technology allowing you to power sensitive electronics with their less then 5% THD (Total Harmonic Distortion).

by Jim, Product Expert
Q: My 500 gal propane tank has a two stage regulator on it . Do I need another regulator at the the generator?
by Michael Schwartz from New York on October 07, 2012

A: A regulator may be required if the pressure exceeds the generators required 10 to 12 inches of water column (0.36 - 0.43 psi)

by Jim, Product Expert
Q: Are mounting bolts for concrete install included in unit packaging?
by Walter from South Carolina on October 06, 2012

A: Generac does not provide the concrete mounting bolts with the generator because it is optional to permanently mount it to concrete.
by Jim, Product Expert
Q: Does the 5870 construction (enclosure make up) meet NFPA 37 condition 2 requirement?
by Bob from New Jersey on October 02, 2012

A: Subsection 4.1.4 of NFPA 37 reads as follows:

“4.1.4 Engines Located Outdoors. Engines, and their weatherproof housings if provided, that are installed outdoors shall be located at least 1.5 m (5 ft) from openings in walls and at least 1.5 m (5 ft) from structures having combustible walls.
A minimum separation shall not be required where the following conditions exist:

(1) The adjacent wall of the structure has a fire resistance rating of at least 1 hour.
(2)* The weatherproof enclosure is constructed of noncombustible materials and it has been demonstrated that a fire within the enclosure will not ignite combustible materials outside the enclosure.”

A4.1.4 (2) Means of demonstrating compliance are by means of full scale fire test or by calculation procedures.
Because of the limited spaces that are frequently available for installation, it has become apparent that exception (2) would be beneficial for many residential and commercial installations. With that in mind, the manufacturer contracted with an independent testing laboratory to run full scale fire tests to assure that the
enclosure would not ignite combustible materials outside the enclosure.

Per Generac Owner's Manual (All 8, 10, 14, 17 & 20kW Air Cooled Automatic Standby Generator):

The criteria was to determine the worst case fire scenario within the generator and to determine the ignitability of items outside the engine enclosure at various distances. The enclosure is constructed of non-combustible materials and the results and conclusions from the independent testing lab indicated that any fire within the generator enclosure would not pose any ignition risk to nearby
combustibles or structures, with or without fire service personnel response.

Based on this testing and the requirements of NFPA 37, Sec 4.1.4, the guidelines for installation of the generators listed above are changed to 18 inches (457mm) from the back side of the generator to a stationary wall or building. For adequate maintenance and airflow clearance, the area above the generator should be at least 4 feet with a minimum of 3 feet at the front and ends of the enclosure.
This would include trees, shrubs and vegetation that could obstruct airflow. See the diagram on the installation drawing within the owner’s manual on under the specs link for details.

Generator exhaust contains DEADLY carbon monoxide gas. This dangerous gas can cause unconsciousness or death. Do not place the unit near windows, doors, fresh air intakes (furnaces, etc.) or any openings in the building or structure, including windows and doors of an attached garage.

by Jim, Product Expert
Q: I have received my 20Kw Generac 5875. Was it shipped with oil or do I need to add oil before i start it up? Or is it just a break in oil (the oil on the dip stickis very light) that needs to be removed and filled with what I will be using in this area? Shipment was timely and arrived n excellent condition.
by Larry from Washington on September 30, 2012

A: These units have been run and tested at the factory prior to being shipped and do not require any type of break-in.

This unit comes filled with oil from the factory. Check the oil level and add the appropriate amount if necessary.

by Jim, Product Expert
Q: Need to run central air, a large screen TV, 2 refrigerators, some lights, and a computer.

What size LP generator would I need?

by Penny Murphy from California on September 28, 2012

A: Proper sizing of the generator is crucial to the success of any generator installation and requires a good working knowledge of electricity and its characteristics, as well as the varying requirements of the electrical equipment comprising the load. A certified electrician needs to be consulted for proper sizing and installation of any generator.

When analyzing the electrical load, consult the manufacturer’s nameplate on each major appliance or piece of equipment to determine its starting and running requirements in terms of watts, amps and voltage. When choosing the generator output select a rating that is approximately 20 to 25% higher than the peak load (for example, if the load is about 8 kilowatts, select a 10 kW generator).

A higher rated generator will operate comfortably at approximately 80% of its full capacity and will provide a margin of flexibility if the load increases in the future.

Q: My service panel is a flush mount in a bedroom
Can this surface mounted transfer switch be feed from the back instead of the side.

Are their other options in this situation, I was thinking order the unit without the transfer and find a matching flush mounted transfer switch

Thanks
Carl


by Carl from Louisiana on August 15, 2012

A: The switch that comes with the 5870 is an indoor switch only and there are no entrance options from the back of the switch.

Generac does not offer any flush mount options other then model 5449 which would replace your existing electrical panel....click link for details....

Generac Model 5449

by Jim, Product Expert
Q: Where do you connect the 12VDC battery charger?
by Darrell from Texas on July 15, 2012

A: The Generac Guardian home standby generators have a built in battery charger in the controller inside the generator called the battery sentinel.

This charger will only charge the battery when needed so it will not overload the battery and the controller in the generator monitors the battery and will notify you when there is a battery issue.
by Jim, Product Expert
Q: Hi Jim, Would 14kw Generac handle 3.5 ton AC unit and some essential circuits?
by Mike Careccia from Texas on July 05, 2012

A: Yes, it should have enough power to get the small central air conditioner working. However, it won't have much left over for other items in the house.

You should consider getting the Smart Circuit version instead. This way, it can power additional circuits in the house when the AC isn't running.

Yes, it will cost a little more, but you'll appreciate the extra appliances running when the AC is off.

Q: Do the generators have a built in propane regulator for the Generac 8 and or 10kw models?
by Curtis Gibson from Virginia on July 03, 2012

A: They do have their own propane regulator but if you are supplying too much service a separate exterior regulator is required. The one in the unit is not adjustable.

by Jim, Product Expert
Q: What size breaker do I need for the main panel for a Generac model 5870?
by Terry from Ohio on May 31, 2012

A: You will need a 40A double pole breaker for the 8kW Essential Circuit model and all other Essential Circuit models (10-17kW) require a 70A double pole breaker.

by Jim, Product Expert
Q: I would prefer installing a concrete pad for the 5870 and would like to know how much wider should the concrete pad be then the unit on all sides?
by Cecilia Blue from Maryland on April 11, 2012

A: There should be a 6" overhang from the generator for a good stable base.
by Jim, Product Expert
Q: Warranty how long?
by Jose from California on March 26, 2012

A: These units have a 3 year manufacturers warranty. You can find the warranty information in the owner's manual which is available on our site under the specs link.

by Jim, Product Expert
Q: Where do I get the installation instructions for the Generac Home Standby Generators?
by T Wanamaker from New York on March 12, 2012

A: The unit comes with the installation instructions or you can find them on the Generac website. The instructions you get without the serial number will be basic.

Q: If I need more wire than the 30 feet supplied, can I splice what ever i need onto it? Also, are the circuit breakers standard ones if i ever need to replace one, or do i have to buy them from Generac?
by Stanley Zydel from New York on February 10, 2012

A: The maximum length you can add is 15 feet as long as local code permits adding length (some do not). If you need to go beyond this length then the entire run of wiring needs to be changed because of the wire sizes/gauge.

Generac typically uses Siemens breakers in their switches which allows for replacement to be easy.

Please keep in mind that you cannot put larger amperage breakers in to replace smaller amperage breakers.

Please always consult with a certified electrician for proper installation and wiring.

by Jim, Product Expert
Q: Hi Jim,is there any codes to how far from a window the standby generator must be.

Thank You
Frank

by Frank Gelsomino from Connecticut on January 24, 2012

A: NFPA 37 - 4.1.4 Engines Located Outdoors. Engines, and their weatherproof housings if provided, that are installed outdoors shall be located at least 1.5 m (5 ft) from openings in walls and at least 1.5 m (5 ft) from structures having combustible walls. A minimum separation shall not be required where either of the following conditions exist:

(1) The adjacent wall of the structure has a fire resistance rating of at least 1 hour.
(2)*The weatherproof enclosure is constructed of noncombustible materials and has been demonstrated that a fire within the enclosure will not ignite combustible materials outside the enclosure.

The above code is referenced in NFPA 70 - Article 445 Generator Locations.

You do need to reference with your local inspector what the requirements are for your local city codes along with the requirements in your area for noncombustible materials.

Always consult with a certified electrician on all installation procedures and processes.

Q: Hey Jim,

What size NG supply line is needed for a 5870 ?

3/4" or 1"

Thanks, Jeff

by Jeff from Pennsylvania on January 19, 2012

Max Distance 7/8kW Generac:

Natural Gas -

3/4" - 55 Feet
1" - 200 Feet

Liquid Propane -

3/4" - 165 Feet
1" - 570 Feet

by Jim, Product Expert
Q: What is a composite pad ?
by CHARLES BLYTHE from North Carolina on April 08, 2011

A: The composite pad is a strong, lightweight mounting pad provided to simplify the installation. By including the pad with the generator, installation time and cost is reduced since a concrete base is no longer a requirement.
by Jim, Product Expert
Q: I was looking at the generac 10k LP generator. Can you hook that up to the 20lb gas grill tanks . Do they sell a manifold to hook up multiple bottles?
by R L from New Jersey on March 19, 2011

A: You cannot use a Grill Propane tank on a home standby generator. These units are designed for use with tanks of 100 gallon or larger to supply adequate fuel for long periods of time.
by Jim, Product Expert
Q: Hello Jim, do you have, or can you recommend stand-by generator installers for the Houston, Texas area? We are in the N.W. Houston area.
by David Reece from Texas on February 13, 2011

A: Since we do not get involved in the installation process and since we ship all over the continental US we do not have a list of installers to provide. You can contact a local Generac dealer who may do installations at a reasonable price and will provide you with the best installation knowledge. You do not necessarily have to purchase a Generac generator from them to utilize their installation and they would be your resource for maintenance and warranty repairs.

Q: How far does a generator has to be from my house?
by Jim from Massachusetts on February 04, 2011

A: The manufacturer recommends the back side of the unit to be set no less then 18 inches from any non-combustible surface and the sides of the unit need at least 36 inches for proper intake and exhaust.

Note: It is recommended to check with your city, county and state codes as they may differ from the manufacturers recommendations.

by Jim, Product Expert
Q: Is this generator (Model 5884) a good choice for off grid solar system backup. 14kw not essential circuit?
by Avery Edwards from Colorado on January 25, 2011

A: The Generac 5884 generator is specifically designed for emergency backup only and will not be warranted in an off-the-grid application.

Generac did come out with a new model specifically designed for off-the-grid and solar applications.

Off Grid Generator

by Jim, Product Expert
Q: What size battery do I need?
by James Fritch from Pennsylvania on January 25, 2011

A: The battery is a Group 26R with 525 cold cranking amps - which is often difficult to find locally.

However, don't get too caught up in the specs. We already sized the battery for this model.

Click on the "Add 12V Start Battery" box when ordering.

The current battery price is listed below the generator pricing by the check box.

We don't sell the batteries individually because they are hazardous materials that must ship via freight. If you bought one individually, it would cost more to ship than the battery is worth.

Since this generator is already shipping via semi-truck, we shrink wrap them together, and the battery tags along for the ride.

by Jim, Product Expert
Q: What kind of oil comes in the generator, and when it is time to change it? Can I run Mobile 1 Synthetic 5W30 year round in central Oklahoma?
by Ron Hopper from Oklahoma on January 24, 2011

A: The Generac standby generators are shipped with 5W30 oil in them and Generac does give the option to use 5W30 Synthetic in needed. The owner's manual covers all oil options and temperature ranges. Oil changes are determined by use and maintenance is also covered in the manual.

Q: Can this generator be anchored to the slab? If so, can you provide an anchor bolt layout
by Gregg Deemer from Texas on January 21, 2011

A: Generac's model 5885, as with all of their standby generators, are anchored to the pallet at all 4 corners with special anchors which can be used to anchor the unit directly to your concrete base using concrete bolts.
by Jim, Product Expert
Q: Jim,
We're interested in this Generac model 5870 and we were wondering under full load what size LP tank capacity should we consider and approximately how much run time could we expect. This will be used in a home application with backup to HVAC needs, a light circuit, sump pump refrigerator /freezer. 3,000 sq ft home. I know that there are many variables and I probably need to get you more information, however, I thought that this would be a good start. Thanks, Mike

by Mike Mitrione from New Jersey on January 18, 2011

A: Proper sizing of the generator is to size it to 80% of the generators full capacity. A higher rated generator will operate comfortably at approximately 80% of its full capacity and will provide a margin of flexibility if the load increases in the future. So if your need is 8kW then you should look at a 10kW standby generator. Tank size is based on how much run time you want available when you lose power. The fuel usage is listed in the owner's manual which you can find our our website under the specs tab for each model. Normally a 100-Gal. tank or larger is best suited.

Warranty Issues Out Of The Box
The new design 8 kw generator will not start in the cold weather. Generac makes the service dealer prove that the generator did not start when the temps were cold. Then they make you purchase a kit that corrects the problem with firmware updates to the controller and other fuel system components.Transfer switch needs a contact update.
