2. The min. pressure switch is linked
to chamber (a) by a hole (option).If the inlet pressure exceeds the
nominal value set at the pressure
switch, the pressure switch
switches through to the automatic
gas burner control.

Ultraviolet Flame detector Periodic Maintenance
1. Clean the viewing window (or focusing lens) when
necessary. Remove the detector (see Troubleshooting
section) and use a clean cloth over the eraser end of apencil. Do not remove the window (or lens) to clean it. If
it is broken or damaged or it is coated with a substance
that cannot be cleaned off, replace it.
2. Keep the flame detection system adjusted for the
smoothest, most reliable operation as recommended bythe burner manufacturer.
3.Replace the sensing tube, coil and shutter assembly, or
viewing window only when necessary to obtain proper

Monthly Maintenance
• 1. Clean every month the gas filters (please refer to the instructions of the filter).
• 2. Clean each month the UV scanner or ionisation probe.
• 3. Clean each month the ignition electrode.
• 4. Keep the combustion air fan clean. Clean the air filters, if available,
each month.• 5. Check every month that the electrical safety shut-off valves are gas
tight in a de-energized position, including the pressure test nippleinstalled between the two valves.

General maintenance instructions
• 1. Clean every week the inlet grille of the combustion air blower or inlet
filter. Checkwhether the fan is dirty and clean, if necessary.
• 2. Regularly clean the gas filter.
• 3. If necessary, replace the flame rod and the spark plug every 6 monthsto obtain optimaloperation.
• 4. Check the safety shut-off valves for possible leakage every month.
• 5. Check the operation of the pressure switches and high temperaturelimit switch everymonth.
• 6. Clean the burner every 6 months.
• 7. See to it that all vents in pressure regulators, pressure switches, etc.are open.
• 8. Clean the feed back lines from pressure switches and regulators every6 months.It will be necessary that the lines are removed completely.
• 9. Keep the installation tidy.
