Important Note
For use with Kerosene* only.
After installing the boiler leave these
instructions with the User.
This appliance is deemed a controlled
service and specific regional statutory
requirements may be applicable.
*Operation on Bio-fuel
All Grant Vortex Eco 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:
• Use a bio-kerosene (B30K
compatible flexible oil line in place of
the oil line supplied with this boiler.
• Have your oil storage tank and oil
supply line (including all pipework,
sight gauges, filters, isolating valves,
fire valves, ed-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.
• Check the suitability of the flue
system with Grant UK.
• 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.
