FAQ:
Q: Do I have to supply the generator with the 100%
loaded BTU rated fuel supply and pipe size?
A: Yes, the generator needs the 100% loaded BTU fuel
rating to start, run and handle loads. The fuel pipe
must be sized for 100% load, regardless of the load.
Q: Does the fuel regulator really need to be 10ft.
(3.05m) from the generator?
A: Yes, per the manufacturer's instruction to assure
proper operation of the regulator and also to meet
code.

Flow Rated”?
A: No, it must be a Full Flow Rated valve and must also
match the required fuel pipe ID dimensions.
Q: Do pipe elbows, tees, drip legs, etc. affect gas
pipe size and flow?
A: Yes, they are restrictions to gas flow. You must add
2.5ft. (.76m) per each elbow, tee, etc. to the overall
calculated distance from the source to the generator.
Q: Can I leave the unit on the shipping pallet and
install it?
A: No, it must be installed per local jurisdiction, code
and the instructions as outlined by the manufacturer.
