Problems
Burnerblowsout.
Low heat, LP gas.
Low heat generated with knob
in "HIGH" position.
Possible Solutions
1. Check for any burner defects.
2. Check for proper burner installation.
3. Make certain the fuel mixture is not too lean.
4. Make sure the gas supply is sufficient.
5. See if the LP tank is empty.
The propane regulator assembly incorporates an excess flow
device designed to supply the grill with sufficient gas flow under
normal conditions, yet control excess gas flow.
Rapid changes in pressure can trigger the excess flow device,
providing a low flame and low temperature. If the tank valve is
turned open to allow gas flow while a burner valve is open, the
surge of pressure will cause the device to activate. The device will
remain closed until the pressure is equalized. This should occur
within 5 seconds.
To ensure this does not cause difficulty in lighting the grill,
follow these instructions:
1. Make sure all burner valves are "OFF."
2. Open the tank valve and wait 5 seconds.
3. Light the burner one at a time following the lighting instructions
listed on page 22. Or you may also find it on the sticker located
on the front panel of cart.
1. Make certain the problem is isolated to only one burner. If it
appears so, clean the orifice and burner, clearing ports of any
obstruction.
2. Check for a bent or kinked fuel hose.
3. Make sure the air shutter is properly adjusted.
4. Check for proper gas supply and pressure.
5. Pre-heat the grill for a full 15 minutes.
6. If using LP gas, check for an empty tank.
