  2 Questions
Q: What is the minimum gas pressure that the unit will operate at? My supplier says the pressure can drop as low as 3 psi during cold weather. Will that be sufficient?
by Andy Weir from Maryland on April 29, 2014

A: Per the specification sheet the Operating Fuel Pressure needs to be between 11 - 14 Water Column (0.396 to 0.504 PSI). 3 PSI is more then enough for the generator to operate.

However, depending on the fuel type the requirements can vary. If you hare going to be using LP then the important thing will be the BTU/HR output from the LP tank as this can drop drastically when temperatures drop.

The 100kW unit requires 1,261,425 BTU/HR at start-up so the supplying tank must output this capacity otherwise the generator will not start.

If you are operating on natural gas then the issue is not related and as long as you have the proper PSI you will be ok.

Q: Could you give me the specs for the concrete installation pad? Should the electrical conduit line come right in the center of the pad?
by Carlos from Maryland on July 07, 2012

A: On the product page you can find the installation drawing in the manufactures spec sheet found under the specs link which shows dimensions and electrical connections.
