Troubleshooting Guide
Problem Possible Solution
Low heat, LP gas
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 trgger 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 .
Low heat, natural gas
Gas pressure is affected by gas line and length of gas line from
house gas line. Follow the recommendations in the chart below.

1. Make certain the problem is isolated to only one burner. If it
appears so, clean the orifice and the 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 full 15 minutes.
6. If using LP gas, check for an empty tank.
