Maintenance
Preventive maintenance is the key to a reliable, safe and
efficient system. The core of any preventive maintenance
system is a list of periodic tasks.
The following are suggestions for a monthly list and a
yearly list.
NOTE: The monthly list and yearly lists are an average
interval. If the environment is dirty, the intervals may be
shorter.
Monthly Checklist
1. Inspect flame sensing devices for good conditions,
and cleanliness.
2. Check for proper inlet air/gas ratios.
3. Test all the alarm systems for proper signals.
4. Check spark rod for damage or distortion.
5. Check valve motors and control valves for free,
smooth action and adjustment.
6. Measure and record the high fire oxygen levels in the
exhaust every month. If there is any change, find the
cause and correct it.
7. View down the peepsights on the burners and down
the exhaust legs of the tubes to check for unusual
flame or carbon build-up. If necessary, remove the
burner to investigate.
