Description

The Baxi Bermuda is a combined central heating boiler and
gas fire designed for installation within a builders opening in
the living space of a dwelling.

These installation and servicing instructions cover all natural
gas models. There are two physical sizes of boiler, the
Bermuda 45 being the smaller. Both Bermuda 45 and 57 are
available with either electronic or manual controls. The
appliance is fitted with an Atmospheric Sensing Device
which will shut the boiler down in the event of adverse flue
conditions. All installation and servicing procedures are the
same for each size of boiler. Any differences in procedure
between electronic and manual control versions are covered
in this booklet.

These instructions relate to the central heating boiler section
of the appliance.

The two models of the boiler have range rated outputs
as shown.

Each appliance is preset at its MIDRANGE heat input rate
and is designed for use on NATURAL GAS only. The boilers
are suitable for fully pumped and pumped central heating
with gravity hot water systems. The propane back boiler is
covered by its own instructions supplied with it. An optional
overheat thermostat kit is available for sealed systems or
where additional system protection is required.

“Benchmark” Log Book

B.S. Codes of Practice

As part of the industry-wide “Benchmark” initiative all Baxi
boilers now include an Installation, Commissioning and
Service Record Log Book. Please read the Log Book
carefully and complete all sections relevant to the appliance
and installation. These include sections on the type of
controls employed, flushing the system, burner operating
pressure etc. The details of the Log Book will be required in
the event of any warranty work. Also, there is a section to be
completed at each subsequent regular service visit.
