1.0 Introduction
The Milborne 500 series is a range of wall hung
boilers comprising 1 or 2 50kW boiler modules
within a single casing. Having a comprehensive
built-in controls package the boiler is particularly
suited to installations that do not have a dedicated
controls installation.
Where larger installations require more power than
a single boiler can produce then multiple boilers
may be installed in a modular arrangement.
Supplied from the factory as fully assembled units,
the boilers are set up for either natural gas or for
LPG prior to delivery. Where required a modification
may be made on site to change from one gas to
another.
Installation
In order to ensure safety and correct operation, the
installation shall always take place in full compliance
with the applicable Law and with the instructions
provided by the Manufacturer, and will always be
carried out by professionally qualified technical
personnel only. The equipment shall be installed in
a suitable area, and connected to the heating
