RECONFIGURING THE FUEL SYSTEM
Note: All models are configured to run on natural gas from the factory.
To reconfigure the fuel system from NG to LP, follow these steps:
1. Turn the main gas supply off.
2. Remove the carburetor fuel hose from the outlet port of the demand regulator (See Detail "A").
3. Disconnect the power wires from the fuel solenoid located on top of the regulator assembly.
4. Loosen the spring clamp on the small fuel enrichment line and remove the hose from the hose barb.
5. Remove the black pipe assembly from the outlet port of the demand regulator.
6. Remove the NG fuel jet (loosen counter clockwise) from the outlet port.
7. Remove the LP fuel jet (loosen counter clockwise) from the jet keeper port on the side of the regulator housing.
Install this jet into the outlet port in the regulator casting.
Note: The jet sizes are stamped on the individual jets. The larger jet size is used for running on NG.
8. Install the previously removed NG jet into the jet keeper port on the side of the regulator housing.
9. Install the previously removed black iron pipe onto the outlet port of the demand regulator.
10. Reverse steps 1-4 in this procedure to reactivate the demand regulator.
11. For LP vapor application substitute LPG fuel inlet decal p/n 050280 for NG fuel inlet decal p/n 050279 (Item 17).
12. When switching fuel types, the proper dip switch settings must be made to the control panel. See owners
manual, fuel section, for more details.
