*Operation on Bio-fuel
All Grant Vortex Pro condensing boilers,
manufactured since May 2011, are suitable
for operation on both standard kerosene
(Class C2 to BS2869) and also bio-kerosene
– up to a 30% blend (B30K).
All burner settings and nozzle sizes (as
detailed in Section 2.3 of this manual)
are correct for both standard kerosene
and bio-kerosene (B30K).
In order to operate this boiler on bio-
kerosene it will be necessary to take
the following actions:
a) Use a bio-kerosene (B30K)
compatible flexible oil line in place of
the oil line supplied with this boiler.
b) Have your oil storage tank and oil
supply line (including all pipework,
sight gauges, filters, isolating valves,
fire valves, de-aeration devices, etc.)
checked for their compatibility with
bio-kerosene (B30K).
Where necessary some, or all, of these
items may have to be replaced with a
bio-kerosene compatible alternative.
c) Check the suitability of the flue system
with Grant UK.
d) Use only bio-kerosene (B30K) that
conforms to OPS24.
IMPORTANT
Under no circumstances should the
boiler be used with bio-kerosene without
the above actions being taken first.
Service Log
It is recommended that the boiler should be regularly serviced, at least once a year,
