Troubleshooting
1Symptoms & remedies
| Symptom | Remedy |
|---|---|
| Gas fuel leaks can cause an explosion. | Check the LP vapor gas or natural gas fuel system for leakage by using a soap and water solution with the fuel system test pressurized to 6–8 ounces per square inch (10–14 inches water column). Do not use a soap solution containing either ammonia or chlorine because both prevent bubble formation. A successful test depends on the ability of the solution to bubble. |
