Care and Cleaning
Professional Outdoor Grills & Cooktops
Main grill
burners
Ensure the gas supply is off, the knobs are in
the OFF position and all surfaces are cool before
removing a burner.
To remove the grill burner, first remove the grill
grate. Then, lift out the heat diffuser. Remove the
anchor bolt and pull the burner up and slightly
to the rear of the unit. The burner head comes
off the orifice at the front. Angle the burner
sideways and remove.
Clean the exterior of the burner(s) with a wire
brush. Be sure burner ports are clear and free
from debris. Clear any clogged ports with a
straightened paper clip. Never use a wooden
toothpick as it may break off and clog the port.
Never enlarge the burner ports. Shake out any
debris through the air shutter. Use a flashlight
to inspect the burner inlet to ensure it is not
blocked. If obstructions can be seen, use a metal
wire coat hanger that has been straightened out
or a pipe cleaner to clear them.
To replace the burner, angle it into the grill box
and position its front corner under the igniter
while sliding the burner head through the grill
orifice hole. Center the burner head onto
the orifice while being careful not to bend the
igniter electrodes. It is extremely important to
center the burner on the orifice properly.
Be careful not to upset the air shutters' original
position (unless readjusting). Lower the rear
burner bracket brace into the cutouts in the grill
bracket brace. Reattach the anchor bolt to
the brace. Make sure all burners are level
and seated in the grill box.
Replace the heat diffuser and the grill grate.
Light all of the burners and check for proper
flame characteristics. Do not attempt to light
the burners prior to replacing all grill parts.
If adjustments are necessary, refer to
the Installation Instructions.
Orifices
With the burner removed, shine a flashlight
through the hole in the grill box to inspect the
orifice to ensure there is no blockage. Use a needle to clear any debris. Be extremely
careful not to enlarge the hole or break off
the needle.
