With contractor parameter HG 00 (see chapter 19 "Contractor level parameters"),
the appliances can be matched to the flue gas system by changing the speed
for both stages.
- The casing must be closed for this setting.
- Remove the cap from the l.h. "flue gas" test port.
- Insert the test probe of the CO
(approx. 70 mm).
- Turn the program selector switch on BM module to "Emissions test". (Illuminated

table adjacent.
- If required, alter the CO content with parameter HG00.

- Measure the flue gas, CO
them in the commissioning report (chapter 29).
- Modifying the parameter HG00 has also adjusted the speed for stage 1. For checking
purposes, the boiler must be set to stage 1.
- Switch HG28 burner operating mode from 2 (two-stage) to 1 (single stage).
- Measure the CO
table adjacent.
- If the value is outside the set value, the CO
pressure (see chapter 28 "Commissioning without Wolf control accessories").
- Reset HG28 burner operating mode from 1 to 2.
- Terminate the emissions test mode by turning the program selector switch on the
BM programming module to the required operating mode. If emissions test mode
is not reset manually, the appliance switches back to the original operating mode
automatically after 15 minutes.
- Remove the test probe and close the test port.
- Check the control parameters and match them to the system if necessary.
- Check the condensate drain.
- Instruct the customer in the operation of the boiler, with the aid of the operating
instructions.
- Complete the commissioning report (chapter 29) and hand over the instructions to
the customer.
- Instruct the customer about the need for annual servicing.
- Instruct the customer about energy saving options.
- Refer your customer to section "Information regarding energy efficient operation" in
the operating instructions.
