Troubleshooting
Introduction
This section is divided into two parts:
•
The first part describes the maintenance
procedures.
• The second part helps identify problems that may
occur and gives advice on how to solve these
problems.
Maintenance
Preventive maintenance is the key to a reliable, safe and
efficient system. The core of any preventive maintenance
program is a list of periodic tasks.
The following are suggestions for a monthly list and a
yearly list.
NOTE: The monthly list and the yearly list are an average
interval. If your environment is dirty, then the intervals may
be shorter. Other standards may take precedence for your
particular application.
Monthly Checklist
• Test (leak test) safety shut-off valves for tightness of
closure.
• Test air pressure switch settings by checking switch
movements against pressure settings and
comparing with actual impulse pressure.
• Visually check ignition cable and connectors.
• Inspect impulse piping for leaks.
• Make sure that the following components are not
damaged or distorted:
- the spark plugs
- the flame sensors
- if applicable, remove and clean all the orifice
plates
