The most effective way of setting the heat source is through the use of a CO
2
measuring device such as a flue gas
analyser. The procedure is as follows:
1.
Put the boiler into ‘Service Mode’. This is done by depressing the service button for three seconds. The
display should show:
2.
Press the [▲] button until the display shows:
3.
Adjust screw 2 to give the CO
2
output as detailed in
Table 14.1.
Turning the screw clockwise will reduce
the CO
2
level, turning anti-clockwise will increase the CO
2
level. On the CP-M+ 120, CP-M+150 and
CP-M+180, this adjustment should be made to the right hand gas valve only.
4.
Press the [▼] button until the display shows:
5.
Adjust screw 1 to give the CO
2
output as detailed in
Table 14.1.
Turning the screw clockwise will
increase the CO
2
level, turning anti-clockwise will reduce the CO
2
level. On the CP-M+120, CP-M+150
and CP-M+180, this adjustment should be made to the right hand gas valve only.
6.
Using the [▲] and [▼] buttons, re-check the combustion reading at high and low fire. Trim the gas
valve settings as necessary.
7.
Once the setting has been completed, depress the service button for 3 seconds to return the boiler to its
normal operating mode.
8.
Record the combustion data and leave with the appliance for future reference.
NOTE:
The dust cap, once reinstalled, should be marked with an anti-tamper indicator.
Combustion figures for Propane firing can be found in
Section 15: LPG FUEL

TEMPERATURE ADJUSTMENT PROCEDURE
Setpoint temperatures are altered via the user control system; refer to
Section 12.8 SETPOINTS
for further
information.
14.6
INSTALLATION NOISE
If care has been taken to follow the manufacturer’s instructions there should be no discernible noise from the
equipment. The allied pump motor may have a level of sound that could lead to consideration for acoustic
insulation, but care must be taken not to impede ventilation or airflow to the pump motor.
