Page 3: Using The Boiler
Remember that... The manual must be read thoroughly, so that you will be able to use the boiler in a safe and sensible way; must be carefully kept. It may be necessary for reference in the future. The lighting up must be carried out by competent and responsible engineer. The manufacturer •... - Page 4 On completion of the work, have a professionally qualified person check their efficiency. Repairs (under guarantee) must be carried out only by a Biasi an approved engineer, us- ing genuine spare parts. Thus do no more than switching off the boiler yourself (see the instructions).
