As manual transfer switches are not manufactured for use with automatic standby generators, we are unable to provide insight regarding how the two could be configured to work with one another. To ensure that you are utilizing the appropriate products for your back-up power needs, we would recommend working with a local independent authorized dealer in your local area.

During times where snowfall is expected, you will want to ensure that snow and/or ice is cleared off of, and away from, the enclosure. There should be no snow piles or large accumulations of snow within five feet of the unit; this is to help ensure proper air flow is provided to the unit, if/when the unit is needed during a utility outage.

When the unit shows a green LED light, this would suggest that the unit is ready to run. However, please note that a yellow LED light alludes to a maintenance reminder that will occur on an annual basis; to determine what particular maintenance reminder is being currently recommended, we would recommend referring to the unit’s control panel.

Try: Running the engine for 5-10 minutes, first.
(Agitates the particulates that may have settled and raises
the temperature of the oil. Hot oil flows faster than cold)
Loosening the oil fill cap and the dip stick.
(Equalizes the air pressure reducing the vacume that
the draining oil creates)
Changing the air filter or the plugs, while it drains.
(If you stand there and watch it, it will take forever)

Generac’s 20kw automatic standby generators, model numbers 6244 and 6730, are fairly similar units. The main difference between these two products, however, is that model number 6244 comes pre-packaged with a 200-amp Smart Switch transfer switch; model number 6730 does not come pre-packaged with a particular transfer switch; the transfer switch would be purchased separately. To review the specifications for both of these products, please use the product’s model number for searching purposes via the following link: http://www.generac.com/dealer-locat....

If the fuel conversion knob proves difficult to turn, we would recommend utilizing pliers to turn the knob as-needed. When using pliers for turning purposes, we would not recommend grabbing the plastic handle of the knob, but rather the metal shaft just below the plastic handle. In the unlikely scenario that additional assistance is required, we would recommend contacting an independent authorized service provider in your local area, or contacting us directly at 888-GENERAC (436-3722).

Per the NFPA 37, 8-22kw air-cooled generators feature the following minimum clearance requirements: The unit should be placed 5 feet from any combustible surface or structure; the unit should be placed 5 feet from any wall opening (i.e. door, window, etc.); the front of the unit, along with the two ventilating sides should be placed 3 feet from any surface or structure including trees, bushes, or shrubs. However, please note that based on independent testing done by Southwest Research Institute, the back of the unit can be placed as close as 18” from any surface or structure. This is due to the fact that our enclosures are complaint with Clause (2) of Section 4.1.4 of NFPA 37. Also, please note that these recommended clearance requirements are superseded by local codes. We would recommend working with your local inspector, to ensure that your unit is installed at a proper distance. Also, this information is provided in Section 3 of your unit’s installation guidelines, entitled “Site Selection and Preparation”.

When operating at full load, Generac’s 20kw automatic standby generator, model number 6730, will require 308,000 btu/hr and 3.5-7” of water column. Comparatively, when operating on a liquid propane fuel source, the unit will require 350,000 btu/hr and 10-12” water column. To ensure that the appropriate pressure is supplied off of your gas meter or propane tank, or if you think that your unit is consuming too much fuel, we would recommend working with your local gas company or propane provider. If you have any other product-related inquiries, please contact us directly at 888-GENERAC (436-3722).

answer 1
Using the correct oil (if you expect the temperature to drop below freezing, we recommend utilizing a 5W-30 Synthetic oil after the unit’s initial break-in period) and cold weather kit will allow the generator to start and run in below freezing temperatures. The kit is thermostatically controlled, and is set from factory to turn on when temperatures drop below 40 degrees Fahrenheit. When operating, the kit’s oil warmer and battery warmer are activated to prevent the battery from freezing. Moreover,the cold weather kit compatible with our current 8-20kW automatic standby generators is model 6212. If you are unsure as to whether this kit will fit your generator, we recommend either contacting your local store or calling Generac directly at 888-GENERAC (436-3722) with your generator model and serial number for confirmation purposes.

Generac’s automatic standby generators are manufactured to function off of a natural gas or liquid propane fuel source. Generac’s 20kw Guardian Series automatic standby generator, model number 6730, requires a fuel pressure of 308,000 btu/hr and 3.5-7” water column when operating at full load on a natural gas fuel source. For a liquid propane fuel source, the unit will require 350,000 btu/hr and 10-12” water column. Also, please note that a 250-gallon liquid propane tank would be our required minimum tank size for LP operation for this particular unit. Actual tank sizing can be provided by the fuel tank provider. We would also recommend working with your local fuel provider to ensure that the proper fuel pressure is provided to your generator.

Error Code 1200 alludes to an Overspeed Alarm. While the cause of this alarm can vary from one scenario to the next, this could potentially be caused by a faulty 7.5 amp fuse, bad air filter, or insufficient fuel pressure. If issues persist after checking the generator’s 7.5 amp fuse, air filter, and fuel pressure provided (which can be verified by your local fuel line provider), we would then recommend contacting an independent authorized service provider in your local area for diagnostic work.
