VENTURI TUBES
6
PORTA-CHEF 100 / 120
Always keep venturi tubes clean. Blockages in the venturi
tubes caused by spiders, insects and nests can cause a
flashback fire. In fact, although the gas grill may still light,
the backed up gas can ignite and cause a fire around the
venturi tubes at the control panel or the side burner.
If a flashback fire occurs, turn off gas at the source
immediately
Inspect and clean the venturi tubes (main burner, side
burner, rear burner) if any of the following symptoms
occur:
1. You smell gas.
2. Your gas grill does not reach temperature.
3. Your gas grill heats unevenly.
4. The burners make popping noises.
INSPECTING & CLEANING
1. Turn off gas by closing the propane cylinder valve
2. When the barbecue is cool , push the burner towards
the valve and lift the burner from the barbecue
housing.
3. Clean the venturi tubes with a pipe cleaner or venturi
cleaning tool (Accessory #77310 or #18270).
4. Lower the burner into position in the gas grill housing,
making sure that the venturi tube is correctly aligned
and fitted on the orifice. Push towards the valve and fit
in place.
