soap and hot water. Remove stubborn residue with a mild
cleanser or scrub brush. DO NOT use a commercial oven
cleaner.
r GRILL INTERIOR: Remove grates. Scrape side with tools

Cleaning the Venturi
WARNING
Spider’s nests or wasp’s mud inside the venturi may cause
re at the valve. If a re occurs, immediately turn off the gas
supply at the control valve. (see representative illustration
in Fig. 36)
REPRESENTATIVE ILLUSTRATION
Note:
Spiders and small insects can spin webs and build nests
inside the venturi tubes. This especially occurs in late
summer and fall before frost when spiders are most active.
These nests can obstruct gas ow and cause a re in and
around the burner valves. Such a re can cause operator
injury and serious damage to the grill. To help prevent a
blockage and ensure full heat output, clean and inspect the
venturi tubes often (once or twice a month). NOTE: Water or
air pressure will not normally clear a spider web.
Steps For Cleaning Venturi:
1. To remove the above obstructions, use an accessory
exible venturi brush or bend a small hook on one end of a
20-inch long exible wire such as the one shown in Fig. 37.
2. Remove the cooking
grates set aside. (Fig. 38)
3. Using a screwdriver, remove the screws holding the
cooktop and set aside. (Fig. 39)
4. Using a screwdriver, remove the self-tapping screws holding
the burner clamps and remove the burners. (Fig. 40)
5. Look inside lower end of venturi tubes for nests, webs or
mud. If present, clean as noted in Step 1, Fig. 37.
6. Inspect and clean the burner if needed.
7. Replace the main burners and burner clamps, and
position the burners in the operating position.
8. Make sure the orice ttings are inside the venturi tubes,
then tighten all self tapping screws. (Fig. 41)
9. Reinstall the cooktop and
the cooking grates.
