Gas Oil is not suitable for use with a Condensing Combi boiler.
4 * Net thermal efficiency.
5 The net flue gas temperatures given above are ± 10%.
6 When commissioning the air damper
must
be adjusted to obtain the correct CO

level.
7 The combustion door test point may be used for CO

and smoke readings only. Do not use this test point for temperature or
efficiency readings.
Flue gas analysis
To allow the boiler to be commissioned and serviced, the boiler is supplied with a combustion test point on the front cleaning door.
When this test point is used please note the following:
1 . The test point is for CO
2
and smoke readings only.
2. The temperature and efficiency readings must be taken from the flue terminal.
