Troubleshooting
Introduction
This section is divided into two parts. The first part
describes the maintenance procedures. The second part
identifies problems that may occur and gives advice on
how to solve these problems.
Maintenance
Preventative maintenance is the key to a reliable, safe
and efficient system. The following are suggested
guidelines for periodic maintenance. Burners in severe
environments or operational conditions should be
checked more frequently.
NOTE: The monthly and yearly lists are an average
interval. If your environment is dirty, the intervals may be
shorter. Check with the local authorities that have
jurisdiction over recommended maintenance schedules.
■ Turn off power to burner and controls before
proceeding with burner inspection.
Monthly Checklist
