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 Also, please note that these recommended clearance requirements are superseded by local codes.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”. To locate your documentation online, please use your product’s model or serial number for searching purposes via the following link: http://www.generac.com/service-supp....

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).

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.

Due to overheating concerns, and a potential for carbon monoxide build-up, Generac’s automatic standby generators should only be installed in an outdoor environment, with the proper clearances dictated by your local codes.

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.

As natural gas flow is not controlled by utility power, it should still in fact be present, in the event of a utility outage. To confirm that this would be the case with your existing configuration, we would recommend contacting your local natural gas supplier.

Generac’s 20kw generator, model number 6730, is an automatic standby unit which is manufactured to run off of a natural gas or liquid propane fuel source; gasoline is not an applicable fueling option.

Question on availability of contact closure reporting an error condition

On a Generac 5505 is there a (normally open) contact closure connection that can be attached to a home alarm system that will accept such a connection that will close on a generator error condition (i.e., operates in parallel with the "red" LED reporting condition).

if so, is it on the main controller board and at which pin positions.

Question

Heat pump compatibility

Can a 20 KW generator be utilized to power a heat pump system at all? Mostly heat pump system I have come across has 60 amp air handler with 30amp auxiliary backup heating strips. This combined load puts a 20KW over full capacity. This is the most popular size residential generator and bang for the buck when fossil fuels are being used to supply the customers primary heating systems. In the north east now fully electric heat pump systems have become much more efficient and popular as well as geo thermal systems to. Both run very effieciently but in very cold weather situations have auxiliary backup electric heaters that kick on and from what I understand within the heat pump systems these heaters are needed for it to operate properly during the defrost cycle so that excludes a relay to lock them out during generator operation. Any thing bigger then a 20kw starts look a little more commercial as well as the price jump is pretty extensive as well. Could you shed some light on this situation please?

Thank you

#2 question - Why did generac stop using the 120volt contactors to feed priority circuits with the Smart switches and convert to 24vac coil voltages? and why have these signals from the smart switch normally closed contacts. It seems a normally open control signal would exclude the DLM contactor coil from being actuated 24/7. This could be done in the controllers altering the program a bit with and few simple gateways. I am curious why they route it this way.

While particular electronics or appliances may be able to be connected to your automatic standby generator and associated transfer switch, we would recommend working with an independent authorized dealer in your local area, to ensure the safe operation of your intended back-up loads. To locate an independent authorized dealer closest to you, please use your postal code for searching purposes via the following link: http://www.generac.com/dealer-locat.... Also, Generac’s Guardian Series 22kw automatic standby generator, model number 6553, is an air-cooled generator; liquid-cooled units will feature alternative enclosures that will require different configurations. Moreover, due to product modifications to particular models of our transfer switches, we have upgraded to a 24v module for load management. While the DLM modules were 120v, as you have alluded, the newer units utilize a PMM that is a 24v part. If you have any other product-related comments, questions, or concerns, please contact us directly at 888-GENERAC (436-3722).
