CONVERSION FROM ONE TYPE OF GAS TO ANOTHER
Each griddle is shipped equipped for use with either natural gas or LP gas (propane). To convert a griddle
from one type of gas to another, do the following:
1. Remove the front panel by removing the knobs and screws on the front.
2. For each burner, replace the orifice with the type appropriate for the type of gas that will be used (see
parts list on page 30). For special gas mixtures, and for altitudes above 2,000 feet, consult factory for
appropriate orifice sizes.
3. For each pilot, replace the pilot assembly (item 20 in the parts list on page 30; 24" models have one pilot,
36" & 48" models have two pilots, and 60" models have three pilots).
4. Re-install the front panel.
5. Remove the hex-threaded plug from the pressure regulator (on the rear of the griddle). Inside is a
removable insert. Pull the insert out, turn it around, and put it back in so that the end facing you has the
letters corresponding to the type of gas that will be used (“NAT” or “LP”). Re-attach the hex-threaded
plug.
6. Check the manifold pressure (the procedure is on page 22).
