Testing The Combustion Parameters - Wolf CGB-75 Assembly And Operating Instructions Manual

Test the combustion parameters with the boiler closed!
Testing the combustion air
- Remove the screw from the l.h. test port
- Open the gas shut-off valve
- Insert the test probe
- Start the gas condensing boiler and turn the heating
water temperature selector to the emissions test symbol
(illuminated ring of the status display flashes yellow)
- Test the temperature and CO
The balanced flue is not gas tight if the CO
> 0.2%; rectify the leak
- After the test has been completed, switch the boiler OFF,
remove the test probe and close the test port. Ensure the
screws are seated firmly.
Testing the flue gas parameters
Flue gas can escape into the installation
room, if the test port is left open. This results
in a risk of asphyxiation.

- Open the gas shut-off valve
- Start the gas condensing centre and turn the temperature
selector to the emissions test symbol (illuminated ring of
the status display flashes yellow)
- Insert the test probe
- Test the flue gas values
- After the test has been completed, remove the test probe
and close the test port. Ensure the screws are seated
firmly.
