4. Install natural gas burner orice marked 49 into each orice
tting. Apply pipe compound to threads on orices prior to in-
stallation.
5. Blue Flame Burner: Place burner shield and burners
into grill and insert burner tubes over orice ttings. Se-
cure each burner with one 1/4-20 x 3/4 phillips screw from
Step 2.
Infrared Burner: Place infrared burners, ignitor, and lugs into
grill and insert burner tubes over orice ttings. Secure each
burner with one 1/4-20 x 3/4 phillips screw from step 2.
6. Grasp valve knobs and remove from valves.
7. The low input adjustment screws are located inside the two
valve stems. Use a small screwdriver to turn each adjustment
screw clockwise 1/4 turn (90 degrees). When valves are in
the "OFF" position, the slot in the adjustment screw should be
vertical. See Figure 37.

9. Connect the grill to the natural gas supply.
Attention: Before lighting your grill check all gas con-
nections including the adjustment screws in valve stems
for gas leaks with a soapy water mixture.
Caution: Do not use the grill if a gas leak is detected until gas
leak is corrected. If a gas leak can not be stopped, do not use
grill. You must contact a qualied repair person.
10. Push valve knobs onto valves.
11. Apply the completed conversion label adjacent to the rating
plate label on the grill.
12. The natural gas inlet pressure at the grill is to be set at 7.0" of
inlet pressure.
13. Ignite burner on grill and observe ame pattern. If ame is yel-
low in color or ame is lifting off burner, the air shutter on blue
ame burners only will require adjustment.
14. Beneath the control panel you can access the air shutter
which is located on the end of the burner tube.
15. Loosen phillips screw at air shutter, open air shutter for a yel-
low ame or close air shutter for a lifting ame. Tighten phillips
screw at air shutter.
16. Ignite burners on grill to verify burner ame characteristics.
17. Replace briquet rack and briquets and reinstall cooking grids.
Installation must conform to local codes or in the absence of local
codes, with the National Fuel Gas Code, ANSI Z223.1/NFPA 54,
Natural Gas and Propane Installation Code, CSA B149.1, or Pro-
pane Storage and Handling Code, B149.2.
Caution: The grill and its individual shutoff valve must be
disconnected from the gas supply piping system during any
system pressure testing at test pressures in excess of 1/2
PSIG.
Caution: The grill must be isolated from the gas supply piping
system by closing its individual manual shutoff valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 PSIG.
