Measuring The Carbon Monoxide Content (Co); Transformer; Replacing - Buderus Logamax plus GB142-24 Servicing Instructions

8.1.27 Measuring the carbon monoxide content (CO)

 Measure the carbon monoxide content on the flue gas sampling
point (see fig. 61).
 The CO values in an air-free condition must be below 400 ppm
or 0.04 vol. %.
 Values of 400 ppm and up indicate that the burner adjustment
may be wrong, the gas burner fitting or the heat exchanger are
dirty or that there may be burner faults.
 You must establish and resolve the cause. The boiler must be
operational when you do this.

8.1.28 Transformer; replacing

 Switch off the power supply of the heating system on the circuit
breaker.
 Set the main switch on the BC10 to "0" (Off).
 Remove the casing.
 Dismantle the cover of the external connection board
(see fig. 62).
 Pull the 4 plugs from the external connection board
(see fig. 63, pos. 1, 2, 3 and 4).
