Problem: Burner will not light or has incomplete
burner flame.
Possible Causes and Solutions:
1. Make sure the 9-volt battery is fresh.
2. Check for spider webs or insect nest in venturi and clean venturi.

has fuel.
4. Misalignment of venturi on orifices. Position venturi over orifices.
5. Burner ports, orifices, valves or hose have blockage. Clean the
components.
6. If burner lights with match but not igniter, check ceramic elec-
trode position in gas collector and condition of igniter wire and
its connections. Perform igniter test and replace any damaged
parts.
7. Crimped fuel supply hose needs straightened.
8. Regulator failure or damaged hose need to be replaced by an
authorized service dealer.

Moving the grill:
Move grill slowly. DO NOT run with or pull the grill behind you;
it could hit you from behind causing injury.
DO NOT move the grill while it is lit or hot, or with objects on
the cooking surface(s) or side table(s).
After moving the grill:
Check all gas connections for leaks that could occur from the
movement.
Check the venturi tubes to be sure they are still over the ori-
fices.
Steps to follow before storing grill:
Clean the grill.
Coat the burner lightly with cooking oil to retard rusting.
