The Boston 2 RS is a range of Floor Standing Room Sealed
Boilers. There is a choice of outputs listed below:

The boilers share a common outer case within which there is
adequate space to fit a central heating pump using standard
fittings. An under work surface top panel is supplied with the
boiler to enable the unit to be fitted under a work top. The
pump cannot be fitted in the case in this type of application
(See PUMP).

All appliances are designed for use on Gas Type G20
(Natural Gas) only, at supply pressure 20 mb.

Each appliance consists essentially of three components,
namely:

1.  COMBUSTION CHAMBER with heat exchanger, burner,
controls and inlet of air duct.

2.  OUTER CASE.

3.  BALANCED FLUE TERMINAL.

“Benchmark” Log Book

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.

The boilers listed below meet requirements of Statutory
Instrument ‘The Boiler (Efficiency) Regulations 1993 No
3083’ and therefore are deemed to meet the requirements of
Directive 92/42/EEc on the efficiency requirements for new
hot water boilers fired with liquid or gaseous fuels.
