Notes:
1. Data given is approximate only.
2. The above settings may have to be adjusted on site for correct operation of burner.
3. Gas oil is not suitable for use with the Grant VORTEX Eco Wall Hung boiler range.
4. The net flue gas temperatures given above are ± 10%.
5. When commissioning the air damper must be adjusted to obtain correct CO
2
level.
6. * Factory settings: 12/16 - 14kW 16/21 - 18.7kW
7. Combustion door test point may be used for CO
2
and smoke readings only. Do not use this test point for temperature or efficiency readings.
8. The installer must amend the boiler data label if the output is changed.
2.4 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:
•
The test point is for CO
2
and smoke
readings only.
•
The boiler efficiency and temperature
must be taken from the flue test
point on high level, vertical and
conventional flue adaptors.
Concentric low level flues do not contain
a test point. The temperature and
efficiency readings must be taken from
the flue terminal.
