Thermo E+ 120/200/320 7 Servicing
If the CO
2
value cannot be adjusted to target value pro-
ceed as follows:
• Inspect burner head on the air side for damage and
replace damaged parts as needed.
• Inspect suction / exhaust gas applications for
damages (reduced cross-section).
• Check heat exchanger for sooting.
• Inspect heat exchanger exhaust gas outlet.
• Inspect combustion chamber.
• Check disc.
• Present?
• Correct disk with respect to thermostat hole?
•Bent?)
• Measure the burner motor speed and compare with
the values in table in 5.6.6, replace if necessary.
• Check the fuel filter for contamination and replace if
required.
• clogged?
• clouding (flocculation of paraffin)?
• different fuels used
(filled different fuels, different cold resistance or
incompatibility)
• Replace fuel nozzle.
• Use other applications, particularly for combustion air
supply.
• Verify fuel pump pressure according to 5.6.9 and
readjust or replace fuel pump if required.
