4.2 COMMISSIONING TEST
The Commissioning Test is based on TB143
Rotate the dial to to COM TEST position and follow the instructions on the screen
TEST 1
check the boiler at Max Gas rate.
The boiler is switched on at Max rate.
The analyser is first zeroed in fresh air.
Once the boiler is stable at max gas flow rate the probe is inserted into the air inlet of
the flue and the CO2 level is measure. The reading needs to be stable and less than
or equal to 0.20%.
TEST 2
The probe is then inserted into the exhaust outlet of the boiler and the RATIO, CO and
CO2 levels are measured. These levels must be as per manufacturers instruction.
Where manufacturers instructions are not available the CO must be less than 350 ppm
and the RATIO must be less than 0.0040.
TEST 3
checks the boiler at minimum gas flow rate where this is possible.
With the boiler operating stabley at minimum gas rate the RATIO, CO and CO2 levels
are measured.
These levels must be as per manufacturers instruction. Where manufacturers
instructions are not available the CO must be less than 350 ppm and the RATIO must
be less than 0.0040.
TEST 4
Measures Flow and Return Temperatures from the boiler
All the measured readings are logged and can be printed or transmitted to PC if an
optional wireless module is fitted.
