Maintenance &
Troubleshooting
This section is divided into two parts. The first part
describes the maintenance procedures, and the second
part helps you to identify problems that may occur and
gives advice on how to solve these problems.
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, then the intervals may
be shorter. Check with local authorities having jurisdiction
on their recommended maintenance schedules.

Monthly Checklist

1. Inspect flame-sensing devices for good condition and
cleanliness.
2. Check for proper air/gas pressures (refer to the
RatioMatic Datasheets, Series 110).
3. Test all the system alarms for proper response signals.
4. Check and clean igniter electrodes.
5. Check the air control valve for smooth, trouble free
operation and adjustment.
6. Check for the proper operation of ventilating
equipment.
7. Test the interlock sequence on all safety equipment.
Manually force each interlock to intentionally fail while
at the same time noting if related equipment closes or
stops as specified by the manufacturer. Test the flame
safeguard by manually shutting off the gas to the
burner.
8. Test the manual gas shut off cocks for proper operation.
9. Clean and/or replace the combustion air blower filter.
10.Inspect and clean the combustion air blower rotor.

Yearly Checklist

2. Test pressure switch settings by checking switch
movements against pressure settings and comparing
these with the actual impulse pressure.

gas shut off cocks.
b. Allow the chamber temperature to cool down to
250°F (121°C).
c. Disconnect the gas piping at a union or the gas
