used with a low level discharge flue.
The above settings may have to
be adjusted on site for the correct
operation of the burner.
Gas Oil is not suitable for use with a
Grant Vortex Pro Combi e boiler.
The net flue gas temperatures given
above are ± 10%.
When commissioning the air damper
must be adjusted to obtain the correct
CO
2
level.
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.
• Final combustion readings must be
taken from the flue terminal (or test
point on flue elbow if Green system
is used) with all panels fitted.
