PREFACE
These technical instructions contain useful and important
information for the correct operation and maintenance of
the remeha central heating boiler, models W40/60-m
ECO.
Furthermore, important instructions are given to ensure
safe and trouble free boiler operation.
Read these instructions carefully before putting the boi-
ler into operation, familiarize yourself with its operation
and control and strictly observe the instructions given.
1. GENERAL DESCRIPTION OF THE BOILER
The remeha W40/60-m ECO is a condensing boiler
which may be installed free standing on a frame or wall
mounted on a bracket. The boiler is suitable for room
sealed fanned flue or open flue fan assisted applications.
The boiler is designed for central heating and indirect
hot water supply at working pressures not exceeding 3
bar. It should be installed on a pumped water circulation
system and is suitable for both open and unvented sys-
tem operation.
The remeha W40/60-m ECO is fitted with a top mounted
premix gas burner firing downwards into an aluminium
heat exchanger. The application of the premix burner,
with its carefully controlled gas/air ratio, water heating
efficiencies of 110.4% (NCV) are obtained in the con-
densing mode with very low CO and NOx emissions.
A condensate collector and a siphon for the condensate
drain is fitted at the bottom of the boiler.
Quick connect latches on the air box cover make the
unit easy to service and maintain.
2. CONSTRUCTION
A DC fan has been mounted on the combustion air
supply side, which guarantees the supply of the correct
quantity of combustion air. Gas injection takes place in a
special mixing section at the inlet of the fan.
As a result, the optimum mixture of gas and air is
achieved in the fan. A pre-mix burner, placed in the top
of the appliance, guarantees optimum combustion.
The remeha W40/60-m ECO heat exchanger is manu-
factured in aluminium, and equipped with conducting
panels for optimum heat transfer.
At the bottom of the appliance, a condensate collector
tray and a siphon are responsible for discharging
condensed water.

If you have any questions, or if you need more infor-
mation about specific subjects relating to this boiler,
please do not hesitate to contact us.
The data published in these technical instructions is
based on the latest information and is subject to revi-
sions.
We reserve the right to modify the design and/or confi-
guration of our products at any moment without being
obliged to adjust earlier supplies accordingly.
The remeha W40/60-m ECO can be easily programmed
and controlled using the built in microprocessor. Actual
and set values can be checked from the read-out display.
Gas and water connections are sited at the bottom of
the boiler whilst combustion air inlet and flue discharge
connections are located at the top of the casing.
For multiple boiler applications refer to the Technical
Information "Multiple units".
The boiler meets the requirements of the EC regulations
of the directives:
- 90-m/396/EEC Gas appliances directive
- 92/42/EEC Efficiency directive
- 73/23/EEC Electrical low voltage directive
- 89/392/EEC Machinery directive
- 89/336/EEC E.M.C. directive
W40-m ECO - PIN-number: 63/AO/6520.
W60-m ECO - PIN-number: 63/AP/6520.
For further advice or information contact Broag Ltd.
The closed air box increases safety, and facilitates
installation in practically any room.
Through the use of microprocessor technology, the
remeha W40/60-m ECO is simple to set and control.
Display windows make it possible to check the current
and target settings.
The gas and water connections are clearly mounted on
the underside of the appliance. The combustion air
supply and flue gas discharge are mounted on the top
of the boiler (100 mm I/D socket).
By using quick connect latches on the air box cover (no
screws), the appliance is also easy to service and
maintain.
