The use of Class D Gas Oil on all Grant Vortex Low NOx and Blue 

Flame boilers DOES NOT comply with ErP requirements or EU

If your boiler uses Bio-Kerosene (B30K), refer to the installation 

and servicing instructions.

aged from 8 years and above and persons

understand the hazards involved. 
Children shall not play with the appliance.
Cleaning and user maintenance shall not 

be made by children without supervision.
