If this is not the case, please contact your supplier. Keep all packaging material (clips, plastic bags, polystyrene foam, etc.) out of reach of children as it may present a potential hazard. In the event of a fault and/or malfunction, turn the appliance off, turn off the gas cock and do not attempt to repair it yourself. Contact a qualified professional instead.

When the work has been completed, ask a qualified technician to check the efficiency of the ducting and the devices.
