You have 15 minutes to complete the tests. After that,
the appliance returns to default mode.

13.2 Measuring CO content of flue gas

Use a multiport flue gas probe for the measurements.
▶ Open one of the flue gas test ports ( Fig. 77).
▶ Insert the flue gas probe approx. 2-3/4 inches (70 mm) into the test
port and seal around it.
▶ Press the emissions test button to select
output.
▶ Measure the CO levels.
DANGER: Risk of flue gas poisoning.
The CO level in the flue gas must be below 200 ppm (air
free).
1)
▶ If 9.4 Vol.% CO
2
can not be achieved due to the gas supplied, use a
lower CO level with CO emissions under 200 ppm
2
(af) instead.
1) 9.4 Vol.% with NG and 11.0 Vol.% with LPG (propane)
▶ Repeatedly press the emissions test button
out.
The display returns to the supply temperature.
▶ Remove flue gas probe and close the flue gas test port properly
( Fig. 81).

Inspection and maintenance

Regular service and maintenance are recommended for a long service
life of the appliance, for efficient and economical operation, and to keep
the environmental impact as low as possible. Owners/operators are
encouraged to sign a service and maintenance contract with a trained
and certified installer for annual servicing and maintenance of the boiler.
DANGER: Explosion!
▶ Close the gas cock prior to working on the gas train.
▶ Check for gas leaks after carrying out work on the gas
train.
DANGER: Risk of flue gas poisoning.
▶ Check for leaks after carrying out work on the venting
system.
DANGER: Risk of electric shock!
▶ Always disconnect the appliance from the mains
power before performing any work. Disconnect the
emergency shutoff switch or disengage the heating
system circuit breaker. Take measures to prevent
accidental reconnection.
NOTICE: Insufficient antifreeze can accelerate
corrosion.
▶ Frost protection level has to be checked annually
during the regular scheduled maintenance of the
condensing boiler.
