Guardian Technologies 04758-2 Manual De Usuario

NOTE:

The natural gas adjustment screw is preset dur-
ing installation and should not need any further 
adjustment.

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 
0.5 psi) to the fuel inlet of the generator MUST 
BE SUPPLIED.

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 1.4).

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. Re-attach the small hose and hose clamp and 

tighten as necessary.

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 perfomance. 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).

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.
