To reconfigure the fuel system from NG to LP, follow these steps:
NOTE:
The primary regulator for the propane supply is NOT INCLUDED with the generator. A fuel pres- sure of 11 to 14 inches of water column (0.4 to
0.5psi) to the fuel inlet of the generator MUST BE SUPPLIED.

REGULATOR HOUSING PORT
1.Turn off the gas supply. (if connected)
2.Open the roof and remove the door.
3.Remove the battery. (if installed)
4.Remove the engine air in baffle located on the left- hand side of the battery compartment. Two M6 screws are located on top of the baffle and two M6 screws are located on the inside of the baffle towards the back.
5.Remove the small hose clamp and hose from the fuel regulator. It may be necessary to pry the hose off of the brass fitting using a screwdriver to gen- tly lift up the hose edge.
6.Remove the small brass hose fitting from the regulator casting.
7.Place the small fuel jet, thread side first, into the threaded hole originally occupied by the brass hose fitting (Figure 1.2).
8.Using a short No. 2 Phillips screw driver, thread the small fuel jet into the regulator casting. Do not over tighten.
9.Apply thread sealant to the threads of the hose fitting and replace it into the regulator body.
10.
11.Replace the engine air in baffle using the four M6 screws.
12.Identify both brass adjustment screws on the regulator.
NOTE:
One adjustment screw can be accessed from the front of the unit and the second can be accessed from the back of the unit enclosure by removing the plastic hole plug. The screw can be turned with a long flat blade screwdriver.
13.To adjust the system to run on LP fuel, turn BOTH adjuster screws 1/2 TURN CLOCKWISE. The system should now be set for maximum power and best performance. DO NOT, UNDER ANY CIRCUMSTANCES, REMOVE THE SET PINS FROM THE REGULATOR HOUSING. THIS WILL VOID THE WARRANTY.
14.It may be necessary to make minor adjustments to the preset adjustment screw settings to achieve maximum power, particularly at higher altitudes. If experiencing problems with the unit producing maximum power, follow the procedure in Section 2.6 (Adjusting the Fuel Regulator).
1.10 LOCATION
1.10.1 GENERATOR
Install the generator set, in its protective enclosure, outdoors, where adequate cooling and ventilating air is always available. Consider these factors:
•Install the unit where air inlet and outlet open- ings will not become obstructed by leaves, grass, snow, etc. If prevailing winds will cause blowing or drifting, consider using a windbreak to protect the unit.
•Install the generator on high ground where water levels will not rise and endanger it.
•Allow sufficient room on all sides of the generator for maintenance and servicing. A good rule is to allow three feet of space on all sides.
•Where strong prevailing winds blow from one direction, face the generator air inlet openings to the prevailing winds.
•Install the generator as close as possible to the fuel supply, to reduce the length of piping.
•Install the generator as close as possible to the transfer switch. HOWEVER, REMEMBER THAT LAWS OR CODES MAY REGULATE THE DISTANCE.
•The genset must be installed on a level surface. The base frame must be level within two (2) inches all around.
