Q: Is the housing for Generac Home Standby Generators (Model 6437) fireproof?

by Robert C. Vose III from Massachusetts on April 26, 2014

A: The following information can be found in the installation manual and the installation guide we have available on the product page under the specs tab in the download document section.....

INSTALLATION GUIDE

The National Fire Protection Association has a standard for the installation and use of stationary combustion engines. That standard is NFPA 37, its requirements limit the spacing of an enclosed generator set from a structure or wall (Figure 1.10).

NFPA 37, Section 4.1.4, Engines Located Outdoors: Engines, and their weatherproof housings if provided, that are installed outdoors shall be located at least 5ft. (1.52m) from openings in walls and at least 5ft. (1.52m) 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 it has been demonstrated that a fire within the enclosure will not ignite combustible materials outside the enclosure.
Annex A — Explanatory Material
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 (Generac) contracted with an independent testing laboratory to run full scale fi retests to assure that the enclosure will not ignite combustible materials outside the enclosure.

NOTE: SOUTHWEST RESEARCH INSTITUE TESTING APPROVES 18IN. (457mm) INSTALLATION MINIMUM FROM STRUCTURE. SOUTHWEST RESEARCH IS A NATIONALLY RECOGNIZED THIRD PARTY TESTING AN LISTING AGENCY.

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.

SOUTHWEST RESEARCH INSTITUTE DECAL (LOCATED INSIDE THE GENERATOR, NEXT TO THE GENERATOR'S DATA DECAL)

SwRI Website Link

BASED ON THIS TESTING AND THE REQUIREMENTS OF NFPA 37, SEC 4.1.4., THE GUIDELINES FOR INSTALLATION OF THE GENERATORS LISTED ARE CHANGED TO 18IN. (457mm) FROM THE BACK SIDE OF THE GENERATOR TO A STATIONALY WALL OR BUILDING. For adequate maintenance and airflow clearance, the area above the generator should be at least 5FT (1.52m) with a minimum of 3ft. (.91m) at the front and ends of the enclosure. This would include trees, shrubs and vegetation shorter than 12in. (305mm) in height. Vegetation taller than 12in. (305mm) in height must have a clearance of 60in. (1524mm). Vegetation not in compliance with these clearance parameters could obstruct air flow. In addition, exhaust fumes from the generator could inhibit plant growth. See Figure 3.1 and the installation drawing within the owner’s manual 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.

Q: Can the Generac model 6437, with 50 amp transfer switch, be used in my home with 100 amp service?

by Nicky from Maine on April 22, 2014

A: Yes, the prewired 50A essential circuit transfer switch can be used in an application with 100A utility service.

The switch is installed as a sub-panel after your main panel allowing you to power specific circuits during a power outage.

by Mike, Product Expert

Q: I am thinking about purchasing an 11kW Generac propane generator for the house. Approx. how long will 100 gallons of propane run the generator or how many gallons an hr. does it burn?

by Charles Cieliesz from Florida on February 13, 2014

A: The minimum tank size recommendation is 250 gallons per Generac due to the starting BTU/HR requirement of the generator and the overall run time.

The 11kW unit has the following fuel consumption rate found in the specs tab on the generator product page....

LP Consumption (50% Load) 1.18 gallons/hr (BTU: 107,085 BTU/HR)
LP Consumption (100% Load) 1.92 gallons/hr (BTU: 174,240 BTU/HR)

We recommend you consult with your LP provider for proper sizing based on your local area temperatures as temperature affects the BTU output from an LP tank.

by Mike, Product Expert

Q: Regarding the Generac 7kW fueled by Nat Gas . Spec states fuel consumption is 85 ft3/hr for 1/2 load. My question is what is this equivalent to in CCF?

by Ed from Pennsylvania on February 06, 2014

A: Natural Gas is usually measured by volume in the United States and is stated in cubic feet. A cubic foot of gas is the amount of gas needed to fill a volume of one cubic foot under set conditions of pressure and temperature.

To measure larger amounts of natural gas, "CCF" (centum cubic-feet) is used to denote 100 cubic feet, and "MCF" (mil cubic-feet) is used to denote 1,000 cubic feet.

With that said, due to the small amount of consumption you wouldn't convert the current ft3/hr to CCF.

However, if you are trying to calculate the cost in relation to therms listed by your natural gas company the conversion is 1000 ft3/hr equals 10 therms.

by Mike, Product Expert

Q: Would winter time installations of automatic generators be good or bad?

by Ron Mills from Michigan on December 30, 2013

A: You can install a generator at any time. However, it would be based on if you are putting down a concrete base as it will not set in cold temperatures. If you are putting down crushed stone or pea gravel it should be no problem.

You can also go with a GenPad (Gen Manufacturer Specific) which is a preform concrete base, so no concrete curing time. These can be installed in any temperature.

Q: I have a low pressure nat. gas line in my residence, what is the largest generator I will be able to run without doing major updates ?

by Chuck from Ohio on December 10, 2013

A: The Generac line of home standby systems can now operate on low pressure natural gas. Their low fuel pressure requirement is 3.5" to 5" of water column (1" of water column = 0.036 PSI).....0.123 PSI to 0.18 PSI. This would be for all sizes from 8kW up to 20kW.

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 requirements in terms of amps and voltage which can be calculated to watts using Ohms Law (Amps x Volts = Watts).

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.

Note: Applications such as commercial, all-electric homes, heat pump systems or geothermal systems require special installation procedures and a certified electrician must be contacted to evaluate and install these types of systems.

Q: If I'm not around when my home standby generator is running, what type of protections systems do the Generac units have?
by Josh from New Jersey on November 13, 2013

A: The generator may have to run for long periods of time with no operator present to
monitor the engine/generator conditions. Therefore, the generator is equipped with a number of systems to automatically shut down the unit to protect it against potentially damaging conditions. Some of these systems are as follows:

• Low Oil Pressure Sensor
• High Temperature Sensor
• Overcrank Sensor
• Overspeed Sensor
• RPM Sensor
• Under-frequency Sensor
• Undervoltage Sensor
• Overvoltage Sensor
• Internal Failure Sensor
• Low Battery Voltage Alarm

The control panel contains a display which alerts the operator when a fault condition occurs. The above list is not all inclusive. For more information about alarms and control panel operation, see Section 3 (Operation) in the owner's manual.

by Mike, Product Expert

Q: What type of oil should I use in my Generac home standby generator?
by Jim from Illinois on November 11, 2013

A: The maintenance section in the Generac's home standby owner's manual lists that the oil type is based on temperature ranges specific in your area.....

SAE-30 above 32º F (0º C)
10W-30 between 40º and -10º F (4º and -23º C)
Synthetic 5W-30 for all temperature ranges

All new models come with SAE-30 oil in them and have been test run at the factory for 25 hours and no break-in is required. The first oil change would be at 2 years or 200 hours, whichever comes first.

by Mike, Product Expert

Q: I'm not sure if this falls into the repair area but, I'm concerned about the sound this generator produces. Is there a way to lower that? Is there sound proofing approved for use for the interior walls of this type of home standby? My neighbors bedroom window will be 20ft from where I plan to install the generator. I would prefer doing something inside the generator as apposed to some type of fencing or other exsternal methods.

by Mark Hernandez from New Jersey on October 23, 2013

A: The manufacturers make every effort to reduce the sound of their generators as best they can keeping within NFPA and UL requirements. There are currently no options or parts available to install inside home standby systems to reduce their db(A) levels.

Your only option is location or sound barriers installed around the unit while keeping within NFPA and manufacturers distance requirements for proper fire protection, air intake and exhaust output.

We recommend consulting with your local inspector or AHJ (Authority Having Jurisdiction) as to the specific local code requirements.

by Mike, Product Expert

Q: Is the smart Switch the actual Automatic Transfer Switch? Or are they different? The specs says that there is an automatic transfer switch included. Also, I would like to know if a bottom pad for the generator included?

by Joseph Pylilo from New York on October 21, 2013

A: The "smart switch" is the automatic transfer switch. The ATS has an internal load manager that will load shed up to 2 AC units preventing the overload of the generator at start-up.

The generator does come with a composite pad already attached to the bottom of the unit (generator base) but a permanent base is required and can be either concrete, crushed stone or pea gravel with a minimum thickness of 3 - 4 inches.

We do offer the GenPad which comes in both 3 inch and 4 inch thickness...here is the link to review their info and pricing....

Generator Pads

Q: I have a new 2013 Generac generator and I'm wondering what oil it came with? I would like to top it off properly after the installation.

by John from New Jersey on October 18, 2013

A: The Generac 2013 automatic standby generators are shipped with a SAE 30 non-synthetic oil. If you are located in an area that receives snow, it is recommended to perform an oil and filter change to switch to a synthetic 5W-30 oil to promote proper generator operation. The cold weather kit is also recommended.

The appropriate intervals for oil changes and other maintenance items will be located in the owner’s manual in the Maintenance Schedule.

Current production models do not require any break in, so if the Maintenance Schedule in the owner's manual indicates that oil changes only need to be done every 2 years or 200 hours, you could drain the existing oil and switch to synthetic 5W-30 right away.

by Mike, Product Expert

Q: What is the recommended time frame to change the break-in oil on my Generac 20kW generator?

by Karin Green from New Jersey on August 10, 2013

A: All of the new 2013 Generac Home Standby generators have been pre-run at the factory for 25 hours. So, no break-in period is required.

by Mike, Product Expert

Q: I just purchased a 11kW generator and would like to know the max distance that I can run 1/2 inch steel pipe to my generator?

by Spencer Aucoin from Louisiana on June 27, 2013

A: The fuel pipe requirements are:

Natural Gas:

1/2" - Cannot Use
3/4" - Max 20 Feet
1" - Max 85 Feet
1-1/4" - Max 370 Feet

Liquid Propane Vapor: (Note: Pipe sizes are using a second stage regulator)

1/2" - Cannot Use
3/4" - Max 70 Feet
1" - Max 255 Feet
1-1/4" - Max 1000 Feet

Natural Gas Pressure: 3.5 - 7 Inches Of Water Column
Liquid Propane Vapor: 10 - 12 Inches Of Water Column

***A properly sized gas pipe is critical to the proper operation of the generator. The generator inlet size has no bearing on the proper gas pipe size.***
by Mike, Product Expert

Q: What is the difference between the Generac model 5871 and their new model 6437 since they are about the same size?
by Mike from Illinois on May 23, 2013

A: Generac went ahead and improved on the design, warranty and ease of installation after listening to consumer reviews and technicians.

They bumped up the warranty an additional 2 years to give it a solid 5 year overall which is one of the highest rated on the market.

They improved on the generator controller by upgrading to a new technology and moved from their very good Nexus design to the new and improved Evolution controller. This new controller has a back-lit interface with LED's that shows the generator status at a glance.

The new Evolution controller includes maintenance reminders and logs, battery condition (no guessing) and over a half-dozen additional alarms the Nexus controller did not have. This thing rocks!

They upgraded the engine to include a no choke carburetor which helps with all weather starting. They changed the fuel selector for natural gas and LP to an easy knob that is easy to access and change fuel type with ease (No tools required).

For the installers they made several changes to help with installation costs and time, minimize errors and accommodate current and future electric code interpretations by re-engineered some of the wiring connections.

With the changes to the carb and engine they were able to change the low fuel pressure rating for Natural Gas down from 5" of Water Column to 3.5" of Water Column. This will help tremendously with low fuel pressure areas in the country so the meters do not need to be changed as often.

With all of these upgrades they have performed I believe Generac's newest model is one of the best out there and comes highly recommended.

Great Generator
Great generator I've connected many of them for customers. However the 12 circuit panel limits you to the number of 15 and 20 amp circuits you can supply to a customer to fit their needs, this panel needs to be a little bit more flexible in regards to sizing of circuits to be more accommodating.

Wonderful Piece Of Mind With This Generator
Ive dreamed about having a house generator for years but either didn't have the money or used what i had on other toys. Finally I made the move and bought this Generac. Its perfect in power, uses propane as I wanted and came in a complete kit. The downside is there is a lot of electronic circuit boards which worry me in the event of an EMP and I'm not sure if the generator case will help shield it at all. Would love to know. It runs once a week to test itself flawlessly. I'm actually hopeful... more

Second Purchase Of Standby Generator
In 2000, I purchased a Generac 10K generator for my rural lake home. I completed the physical installation and my son-in-law (an electrician) made the electrical connections.

We reviewed the startup instructions and everything worked flawlessly. This model had a 120V convenience outlet in the battery area, so I purchased a thermo-controlled batter warming pad for around 8 or 9 dollars and placed it under the battery.

Since my home was dependent on electricity for water, the Generac saved... more

The installation is complete. It all went very well. It REALLY helped to have access to all the installation manuals and owners manuals BEFORE I even bought the generator. I was able to study them and determine if I could do the job myself (I am a controls engineer at an automotive manufacturing plant).
