2. Defective pilot or misaligned electrode at pilot
3. No or low gas pressure
1.Replace ignitor if wire is prop- erly connected and you have no spark
2.Using a match, light pilot. If pi- lot lights turn off pilot and push piezo again. If pilot lights, an improper gas/air mixture cause improper lighting and a longer purge period is recommended.
