Does the generator need a engine block heater in Ohio?
-
OrwinOrchard· 12 years ago
Helpful?

Generac· 13 years ago
For our automatic standby generators, if you expect the temperature to drop below freezing, we recommend utilizing a 5W-30 Synthetic oil, which can be used year round. We also recommend using a cold weather kit, which includes a battery warmer and a crankcase heater. Using the correct oil and cold weather kit will allow the generator to start and run in below freezing temperatures. There are no other heaters or accessories that would be required for cold weather starting, provided the cold weather kit is properly installed.

In extremely cold weather conditions a block heater is recommended. Northern does carry the cold weather kit which includes an automatic thermostatically controlled battery pad warmer and a crankcase heater.

Yes the transfer switch goes between the meter base and the existing panel. The transfer panel comes with a service rated disconnect.

You do want the transfer switch to match the service that you have; so in your case you would want a 200 amp transfer switch.

What is the clearance of the generator from a House
-
ProductExpert19· 13 years ago
The intake and exhaust, which are the short ends of the generator, and the front side of the generator require a minimum clearance of 36” from a wall. However, the distance required from the unit to any window, vent, door, opening into the home, an overhang, and trees, plants or shrubs over 12” in height is a minimum of 60”. Further information on proper installation can be found in the installation guidelines.
Helpful?

Generac· 13 years ago
The Guardian Series automatic standby generators feature a one hour fire rated enclosure, and are in compliance with NFPA 37 Article 4.1.4 Condition 2 for clearance from combustible construction. This means that the back side of the generator can be installed a minimum of 18” from a surface. The intake and exhaust, which are the short ends of the generator, and the front side of the generator require a minimum clearance of 36” from a wall. However, the distance required from the unit to any window, vent, door, opening into the home, an overhang, and trees, plants or shrubs over 12” in height is a minimum of 60”. Further information on proper installation can be found in the installation guidelines. A copy of the installation guidelines can be located by searching the model or serial number for the generator here: http://www.generac.com/Service/ManualSearch/. We recommend contacting your local inspector, as state and local codes may vary, and will supersede manufacturer recommendations for installation near a structure.

How much natural gas is used per hour at 1/2 load.
I asked this question previously but apparently was mis-understood because I did not get the answer that I was looking for. So I will re-state the question more clearly.
How many therms of natural gas does this generator use in one hour running at 1/2 load. And how many therms of natural gas does this generator use in one hour at full load ? Thank You for you reply.p.s Please reply in therms as that is how I am billed for my natural gas useage.

ProductExpert19· 14 years ago
The fuel volume and pressure requirements for natural gas at full load are 5-7” water column at 261,000 BTU/hr. For half load, the fuel volume and pressure requirements are 5-7” water column at 183,000 BTU/hr. 1 therm = 100,000 BTU's.
