29. If a combustion analyser is to be used there are test points provided on the front of the room sealed cover. The
right hand grommet is for air and the left hand one is for flue gas. The boiler must reach operating temperature
before this test is carried out (normally 10-15 minutes). CO/CO2 ratio should not exceed 0.0080. Immediatly

6.04 Flue Gas Analysis
1.
The appliance should be checked visually for obvious defects.
2.
After removing the jacket on the boiler there are two test point, one for flue gas and the other for air.
3.
Open the air and flue gas test points;
4.
Introduce the probes as far as the retainer;
5.
Turn on the hot water tap;
6.
Turn the domestic hot water stat to maximum;
7.
Allow the boiler to reach thermal equilibrium (10 - 15 min.);
8.
Take reading;
9.
The CO/CO2 ratio should be 0.0040 or below. If the reading is above this then a full strip down service must be
carried out and the cause remedied.
10. Following a full strip down service and after
reaching thermal equilibrium the permissible
reading is 0.008 or below.
reading is 0.008 or below.
N.B.: To ensure correct readings the boiler must have
reached normal operating temperature. Testing
the boiler before thermal equilibrium has been at-
tained will give incorrect readings.
the boiler before thermal equilibrium has been at-
tained will give incorrect readings.
N.B.: If you have only 1 probe, measure separately
air and flue gas, close the test point not in use.
