21. Reattach the control knobs onto the manifold

stems, making sure “OFF” is facing upwards. (See Fig. 12)

22. Place burners and front heat shield back into the

grill body, making sure the burner tabs fall downward through cutouts. (See Fig. 11 & 10)

23. Line up the burners with the valv

es on the mani-

fold, making sure they are level. (See Fig. 20 &

21)

24. Reattach the ignitors and their heat shields,

removed in step four (4), to the burners. (See Fig. 4, on page 1)

25. Reattach the rear heat shield before attaching

the front heat shield to be sure the burners remain over the valves. (See Fig. 22)

Installing the NG regulator

1. Remove the LP regulator from the main gas pipe using an

djustable wrench. Located inside the cart on bottom of grill

a head. (See Fig. 23)

Remaining end still connected will be removed later.

2. Remove the brass fitting from main gas line. (See Fig. 24)

** Note – for the following steps, the supplied pipe dope

needs to be applied to all indicated fittings before the fittings are screwed in.

Pipe dope should not be used on any flared fittings!

3. Attach the “T” fitting to the main gas line as shown. Tighten with wrench. (See Fig. 25)

4. Attach one of 3/8” to flared fitting to the “T” fitting as shown. Remember to apply pipe dope to the non-flared end. Tighten with wrench. (See Fig. 26)

5. Attach one end of the supplied hose to the flared fitting on the side of the “T” connector. (See Fig. 27) The other end of the hose will be attached to the side burner later.

Converting the Side Burner to NG

1. Loosen the gas supply hose attached to the side burner valve using an adjustable wrench. (See Fig. 29)

2. Once removed, the LP regulator and hose can be completely removed from the grill. (See Fig. 29)

3. Loosen the aluminum line going from the side burner valve to the side burner, using and adjustable wrench. (See Fig. 30)

Note: First remove the aluminum line fitting, then remove the fitting attached to the valve.

Remove the aluminum line completely from the side burner valve (See Fig. 31)

4. Remove the control knob from the front of the side burner. (Use a pair of pliers with a cloth to avoid any scratches or dents on the knobs) (See Fig. 32)
