4.2.0
By-pass
For application where the air duty
exceeds that required to maintain the
criteria stated above then, a parallel by-
pass is required to conduct the excess air
around the heat exchanger.
Such a by-pass should be so designed
and constructed so that the air flow
(m³/h) across the enclosure (duct
channel) around the tube is maintained
between the minimum and maximum
figures.
The recommended by-passes per type of
unit are shown in figures 16,17,18 & 19
We refer also to §11.0.
4.3.0
Important remark
The air velocity needs to be equal over
the total area of the heating section so
that even distribution is achieved over
the entire heat exchanger tube assembly.
Attention :
Special attention is necessary assessing
air velocities especially in a push through
system, baffles and or an air-stream
diverter/s may be necessary to ensure an
even distribution of the air-flow.
Part or the whole of the tubes may
become damaged or can be the source of
poor combustion if the air velocity as
recommended above is not applied.

Burner & controls section
5.1
The following conditions must be
observed when applying the heating
module with its burner controls.
5.1.1 An enclosure containing EURO-C 4000
heating modules shall be so constructed
that it is fully protected against the
rigours of the environment in which it is
intended to operate.
5.1.2 When applied as an RJL (roof top/outdoor
unit) the enclosure into which it is
fitted,must comply with protection grade
IP 45.
5.1.3 Access to compartments enclosing the
burner and its controls must be provided
with panels, doors, etc. that are intended
to be opened only by the use of a tool
(key). Such panels must be designed to
ensure that after repeated removal and
replacement their integrity is not
jeopardised, i.e. seals and insulate etc.
remain serviceable.
5.1.4 Openings from the outside of the air
handler, e.g. gas and electrical services,
shall not be larger than to permit a ball of
16 mm diameter to pass with a pressure
of 5N.
5.1.5 Dimensions (mm) of control cabinet
With reference to figure 4, the
dimensions of the control cabinet must
be in accordance with table 3

Warning
Use of EURO-C heating modules for
purposes other than those described
above could result in severe personal
injury or death and cause property
damage.
The manufacturer warranties are void if
departure from the intended use is
undertaken
.
Warning
This heating module may not be used
where the air handler/heating system in
which it is installed will be used where,
flammable substances/vapours exist or
where the atmosphere contains
chlorinated or haloginated hydrocarbons,
silicones, aluminium oxides, etc.
The manufacturer warranties are void
if
these restrictions are not observed
