Recheck burner start-up, thermostat fuction and control function repeatedly.
Note the ignition values in the measurement log.
NOTICE:
If the waste gas temperature falls below the permitted limit in low temperature boilers (NT) in the MIN po-
sition, a chimney sweeper must verify whether the chimney permits these temperatures.
It might be necessary to correct the setting of the MIN cam in direction 'OPEN' in order to reach the min.
permitted waste gas temperature.
In contrast: in accordance with DIN 4702-6, a low waste gas temperature up to < 50°C is desirable for con-
densing boilers.
12.8 Final check
Prior to the generation of a final boiler protocol and handover of the burner system to the client, proper ther-
mostat function for the upper range of boiler temperatures must be verified in repeated switching cycles.
All fixing and terminal parts on air dampers, gas dampers, switching cams, adjustment levers, etc. must be
checked for proper seating. The burner must be started up repeatedly.
Setting:
Temperature limiter
