COMMISSIONING TEST
The Commissioning Test is based on TB143
Introduced in April 2013, Technical Bulletin 143 from the Heating and Hotwater Industry Council (HHIC), outlines a safer, clear and comprehensive
procedure for commissioning condensing boilers without airgas ratio valves .
Rotate the dial to “COM TEST” position and follow the instructions on the screen
TEST 1
check the boiler at High Fire rate .
The boiler is switched on at High Fire rate .
The analyzer is first zeroed in
outside fresh air
.
Once the boiler is stable at high fire rate the probe is inserted into the air inlet of the flue and the CO
2
level is measured . 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 CO
2
levels are measured . These levels must be as per
manufacturers instruction . Where manufacturer’s 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 Low Fire flow rate where this is possible .
With the boiler operating stably at Low Fire rate the Ratio, CO and CO
2
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 Flue 2 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 .
PRESSURE/TEMPERATURE TESTING
WARNING!
NEVER ATTEMPT TO TAKE A PRESSURE READING WITHOUT KNOWING THE MAXIMUM PRESSURE THAT MIGHT BE PRESENT . THIS
INSTRUMENT’S PRESSURE TRANSDUCER IS
RATED AT 1.1 PSI WITH A MAXIMUM OVER RANGE OF 5.8 PSI.
Select “PRS/TEMP” . The pump stops automatically . Press
to auto-zero the pressure sensor . Using the black connectors and manometer hose,
connect to P1 for single pressure or P1 and P2 for differential pressure .
Normal response or smoothed (damped) response can be selected via “MENU” .
‘High’ or ‘Low’ resolution readings can be selected via “MENU” .
Pressure units can be selected via “MENU” .
