IMPORTANT
After completing the servicing or replacement of components always:
• Test for gas soundness.
• Check the water system is correctly lled and free of air. Air in the boiler
could cause damage to the heat exchanger.
•With the system hot examine all water connections for soundness.
• Check the gas rate and measure the combustion CO/CO2content. The
CO/CO2 ratio of the ue gas should not be greater than 0.004 ratio & the
CO should not exceed 350ppm.
• Carry out functional checks as appropriate.
It is the law that any service work must be
carried out by a Suitably qualied Gas Safe
Registered Engineer. In IE service work
must be carried out by a competent person.
WARNING
ALWAYS TURN OFF THE GAS SUPPLY
AT THE GAS SERVICE COCK, AND

1. Remove the existing ue condensate collector from its
location in the boiler ue outlet as shown in the image
above.
2. Once the condensate collector has been removed, insert
the ue adaptor into the ue outlet ensuring that it is pushed
past the lip seal inside the ue outlet and sits on top of the
supports that are part of the casting.
3. The ue adaptor has a cutaway which needs to be
orientated to the rear of the boiler for clearance against the
elbow of the ue outlet as shown in the image below.
4. Ensure that the lip seal is in place within the groove on the
ue outlet and adjust where necessary before reinstalling
the ue condensate collector.

GAS VALVE ADJUSTMENT
Maximum rate adjustment
1. Switch the boiler on and set the boiler into service mode
maximum which will last for 10 mins but can be exited
earlier.
2. To ensure the boiler operates at maximum rate without
modulating, set the fan speed to maximum following the
steps in the gas valve adjustment diagram on the next page.
3. Using the maximum rate adjustment screw adjust the valve
until the CO2 valve measures 10.8% (Note:- clockwise
reduces the CO2).
Minimum rate adjustment
4. To ensure the boiler operates at minimum rate without
modulating, set the fan speed to minimum following the
steps in the gas valve adjustment diagram on the next page.
5. Using the minimum rate adjustment screw adjust the valve
until the CO2 valve measures 10.0% (Note:- Anticlockwise
reduces the CO2).
6. Reset the boiler back to maximum rate and measure the
CO2.
If this does not measure 10.8% ± 0.2% repeat steps 3 to 5 above. Press the Home button to return to the Home screen. Seal the
adjustment screw with tamper proof paint and replace caps where applicable.
