IMPORTANT – SAFETY
It is essential that the following instructions and adjustments are carried out by qualified engineers
that are experienced in forced draught gas and pressure jet oil burner commissioning. In the UK it is
a legal requirement that these engineers should also be CORGI registered. Nu-way cannot be held
responsible for any consequential damage, loss or personal injury as a result of customers failing to
follow these instructions, or as a result of misuse. Your attention is drawn to the
Emergency
