Does the 5870 construction (enclosure make up) meet NFPA 37 condition 2 requirement?
Bob 
from New Jersey 
October 02, 2012
Answer
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.

Does this self check and how long does it last on tank LP?
Craig Pujol 
from Louisiana 
August 30, 2012
Answer
When properly connected to a Generac automatic transfer switch this unit will do a weekly maintenance test.

Generac recommends a minimum 200 Gallon tank for proper emergency backup.

Fuel Consumption - LP
50% Load - 1.56 Gal/Hr
100% Load - 2.30 Gal/Hr

Can you suggest a generator package that will work with the Model 5449 Panel? Looking for something around 8-12kW. Thanks!
Andres 
from Massachusetts 
June 03, 2012
Answer
Any of the individual Generac home standby generators will work with model 5449 transfer panel.....here are links to the 8kW, 10kW and the 14kW models available.

Generac Guardian Model 5882 - 8kW

Generac Guardian Model 5883 - 10kW

Generac Guardian Model 5884 - 14kW

If I purchase a 14 KW Generac standby Gen with the 14 circuit switch, can I swap out the 40 amp breaker for a 50 amp?
Paul 
from New Jersey 
May 24, 2012
Answer
No, the internal wiring of the switch is not capable of handling the higher amperage rating. If you need a 50A breaker in the switch you need to purchase the generator by itself, model 5884, and then purchase the 16ckt switch, model RTS16EZA1, which has a 50A breaker.

Hey Jim, What size NG supply line is needed for a 5870 ? 3/4" or 1" Thanks, Jeff
Jeff  
from Pennsylvania 
January 19, 2012
Answer
Pipe diameter is based on the distance the generator is from the fuel source and Generac recommends the following which should be confirmed by your installing plumber.

Max Distance 7/8kW Generac:

Natural Gas -

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

Liquid Propane -

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

Jim I have a 100 amp Pre-Nexus service rated transfer switch. Can I use this with a nexus generator? Ive heard there is some special wiring for the battery charger to work
Mike Noonan 
from Michigan 
April 18, 2011
Answer
There is a special kit that needs to be added to the switch to accept the 120V connection which provides the power to the internal generator controller for the charger. These kits are available from your local Generac dealer - Part Number: 0H93030SRV.

How far does a generator has to be from my house?
Jim 
from Massachusetts 
February 04, 2011
Answer
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.

Is this generator (Model 5884) a good choice for off grid solar system backup. 14kw not essential circuit?
Avery Edwards 
from Colorado 
January 25, 2011
Answer
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.

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?
Ron Hopper 
from Oklahoma 
January 24, 2011
Answer
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.

How long would the generator run on say a BBQ size propane tank?
Ryan 
from Washington 
January 23, 2011
Answer
The Generac standby generators are not designed to operate on a 20# propane tank and they recommend a minimum 100 Gal tank for minimum backup availability.
+
Can this generator be anchored to the slab? If so, can you provide an anchor bolt layout
Gregg Deemer 
from Texas 
January 21, 2011
Answer
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.
