As a follow-up to my question earlier today what are the main or important differences,if any, between the Generac Guardian 10 kw nat. gas generator Model 5883 and the Model 6439.
Bob Richardson 
from New York 
May 28, 2013
Answer
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.

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.

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.

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.
