Combustion Tests
Combustion tests must be carried out using an approved test kit.
The householder should be left necessary details of the test.
To obtain the above, first fit a manifold and pressure gauge 0-300 p.s.i. to the oil pump.
Next set the Boiler control stat to 80°C and switch on. Ensure all controls are calling for
heat.
Having bled the air out of the system, adjust the pump pressure.
Test holes are provided for all flues.
Check the smoke reading with the Boiler up to temperature and then measure the CO² and
flue gas temperature.
Reducing air into the burner decreases the flue gas temperature and increases the CO².
See Section 11 for typical burner settings and test data.
IMPORTANT
DO NOT drill any test holes in balanced flues.
ALWAYS refit test hole bolts.
