DOMESTIC HOT WATER SYSTEM DESIGN
ECOSY 24 E/ 28 E
only
●
Copper tubing must be used for the domestic hot
water system. Unnecessary pressure losses should be
avoided.
●
A flow restrictor is factory fitted in the cold water
inlet before the thermostatic valve. This limits the flow
through the boiler to a maximum of 12 l/min.
BOILER LOCATION
Clearances
The position of the boiler must be such that there is
adequate space for servicing.
The recommended clearances are:
40 mm either side of the boiler.
600 mm at the front of the boiler.
300 mm below the boiler.
Fixing jig
The fixing jig comprises three parts:
1) The connecting plate which allows the connec-
tion and soundness testing of all the pipework be-
fore the boiler is fitted and helps support the weight
of the boiler.
2) The hook which supports the weight of the boiler.
3) The template which ensures the hook and con-
necting plate are correctly fitted relative to one
another.
●
Place template on wall in required position, mak-
ing allowances for the necessary clearances etc.
Note:
It is permissible to install the boiler with reduced
clearances at the bottom and sides of the boiler
PROVIDING that adequate consideration is given
for Servicing/Repairs at a later date. If any doubt
exists, contact the
Saunier Duval Technical Helpline
01773 828400.
●
Mark the position of the holes for the hook and
connecting plate.
●
Drill, plug and fix the connecting plate and hook
to the wall using suitable screws.
●
Check that both the hook and connecting plate
are level.
If the boiler is not installed immediately, protect the
various couplings to prevent any ingress of foreign
materials e.g. plaster, paint etc.
Terminal position
The minimum acceptable spacings from the termi-
nal to obstructions and ventilation openings are
shown in
diagram 10.
The boiler must be installed so that the terminal is
exposed to the external air.
Should any doubt exist as to the permissible posi-
tion of the terminal, contact the
Saunier Duval Tech-
nical Helpline 01773 828400.
Cupboard or compartment ventilation
The boiler can be fitted in a cupboard or compart-
ment as long as adequate permanent high and low
level ventilation is provided in accordance with
ventilation requirements

Hard water areas
The temperatures within the heat exanger are
limited by the boiler control system to minimise scale
formation within the hot water pipework.
However, areas where the water is "hard" (i.e. more
than 200 mg/litre), it is recommended that the
domestic hot water temperature is reduced to 55
°
C
or below. Refer to the Controls and lighting section
to reset the domestic hot water temperature.
It is also recommended that a scale reducer is fitted.
Refer to the manufacturers instructions or consult the
local water company for additional advice.
