About the Boiler

• This is a Floor Mounted, Fan Assisted Balanced Flue
Gas Boiler. This boiler is for use with Natural Gas (G20)
only at 20 mbar and for use in GB/IE only.
• The information given in these instructions will help you
obtain the maximum comfort from your boiler with the
minimum trouble and cost. Please take time to read
through these instructions as they will help you
understand how to get the best use out of the boiler.
• Powermax HE is a condensing combination boiler in
which the gas burner heats the contents of the built-in
hot water store to provide domestic hot water. A pre-
mixed burner is used to ensure that the gas is burned
cleanly and efficiently.
• To reduce running costs, timed operation of the central
heating is essential and a Powermax programmer is
built-in to provide this function. It enables both hot water
and heating periods to be timed for both comfort and
economy. Your installer may have fitted another make
of programmer remote from the boiler and should have
provided you with instructions on its use.
