Care, Maintenance and Cleaning (continued)

STAINLESS STEEL

After initial usage, areas of the grill may discolor from the intense heat given off by the burners, this is normal and not considered a defect.

Purchase a mild stainless steel cleaner and rub in the direction of the grain of the metal. Specks of grease can gather on the surface of the stainless steel and bake on to the surface and give a worn appearance. For removal, use an non-abrasive oven cleaner in conjunction with a stainless cleaner.

NOTE: Always scrub in the direction of the grain.

BATTERY REPLACEMENT (FOR IGNITER):

The igniter is powered by a standard 9 Volt battery. To replace the battery, locate the igniter module by opening the right side door. The igniter module is located near the top edge of the right side panel. When installing a fresh battery, observe polarity as marked on the igniter module and push in firmly (Fig. 50).

Cleaning the Venturi

WARNING

Spider’s nests or wasp’s mud inside the venturi may cause fire at the valve. If a fire occurs, immediately turn off the gas supply at the L.P. cylinder valve (see representative illustration in Fig. 51).

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 flow and cause a fire in and around the burner valves. Such a fire 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 flexible venturi brush or bend a small hook on one end of a 20-inch long flexible wire such as the one shown in Fig. 52.
