Interior Cleaning
It is a good idea to occasionally burn off residue in
your grill. Run the grill with the main burners on high
with the lid closed for at least 90 minutes. This will
burn off accumulated residue and dry everything out.
The more you use sauces or grill fatty foods, the more
frequently you should do this burn cycle.
The inside of the grill lid will darken over time. We
recommend cleaning it annually. You will need to
use Bar Keepers Friend (recommended) and a
lot of elbow grease or a harsh oven cleaner (not
recommended). If you choose to use oven cleaner:
do not get it into the ceramic rotisserie burner; do
not get it on igniters; do not get it on the electronics
or wires; do not get it on the cooking surface; and do
make sure you thoroughly rinse off all of the cleaner
before cooking on your grill. Be careful when rinsing
off the oven cleaner not to stain your patio.
Again, we
strongly recommend the use of Bar Keepers Friend
and discourage the use of oven cleaner.
Main Burner Care
The burners should be visually inspected and cleaned
four times a year.
To access the burners, first make sure the grill is
completely cooled. Ensure the grill control valves are
in the OFF position and turn off the main gas supply.
Remove the cooking surfaces and the heat diffusers.
Release the burner (Figure 23:A) from the burner
support bracket at the rear (Figure 23:B) by removing
the retaining pin (Figure 23:C). You can now lift the
burner off the burner support bracket from the rear
and then slide it rearward off the orifice (Figure 23:F).
Visually inspect each burner to confirm it is structurally
sound and that none of the ports are clogged. Shine
a flashlight through the end of the venturi (see Figure
23:E) to inspect for any blockage.
Carefully clean the burner using a brass brush.
Clogged burner ports may be cleared with a small
metal pick. Do not use a toothpick or anything else
that could break off inside the burner ports.
After cleaning the burners, reinstall them into the
grill. Slide the venturi end of the burner through the
hole in the interior grill box toward the front of the
grill and seat the burner opening over the orifice
(Figure 23:F) mounted on the valve. Lower the burner
onto the burner brackets (Figure 23:B) so that the
post (Figure 23:D) on the bottom rear of the burner
drops through the corresponding hole in the burner
bracket. You must make sure the opening at the front
of the burner is centered over the brass orifice and
securely engaged (Figure 23:F and 20:D ). Once you
have confirmed this, reinsert the locking pin under the
bracket to secure the burner. The retention pins must
be installed before using the grill.
