Installation instructions E-SHR series page 11
6.6 Hot water supply E-SHR 15 and 24
Depending of the comfort preferences different external
hot water cylinders can be connected to E-SHR 15 and
24 solo boiler. The choice of the cylinder depends on the
coil output. The coil output must be compatible with the
boiler output. The E-SHR 15 and 24 are provided with an
internal DHW control. The electrical connection can be
made on the connection terminal in the Control Tower.
See the wiring diagram on page 13 and 14.
6.7 Condensation drain pipe
The collective condensation drain pipe should be
connected to the drain by means of an open connection
(Tundish Break). Removing the possibility of foul drain
gases and water backing up into the boiler. The drain
connection should have a minimum diameter of 25 mm.
The following components are connected to the combi-
nation condensation drain pipe:
- Condensation discharge;
- Safety valve;
Draining of the condensation water to the
external rain guttering is not permitted in
view of the danger of freezing.
Before putting the boiler into operation fill the
siphon with 300 ml of water.
6.8 Flue gas exhaust system and air supply
system
The appliance connection diameter is 80/125 mm, to which
the flue gas outlet and air supply system can be fitted, with
or without elbow pieces. The maximum permissible pipe
length is set out in Table 5.
United Kingdom:
The flue gas outlet and air supply installation must
comply with the current regulation requirements. IG UP
10 and BS 715.
Ireland:
- Irish standard is 813 section 9.10.1
We recommend that you use a stainless steel flue gas
outlet material. Using the ATAG icicle-free roof outlet
prevents ice from building up on the roof outlet.
Before connecting any
flue pipe or fittings into
the adaptor (1), Please
remove both flue gas
test nipples, items 2 &
3. Make flue or fitting
connection, Re-
connect both flue gas test nipples.
Flue systems must comply with the current regulations.
It is essential that in practice, products of combustion
discharging from the terminal cannot re- enter the building
or any other adjacent building through ventilators,
windows, doors, other sources of natural or mechanical air
infiltration from forced ventilation or air conditioning
systems.
Horizontal sections of flue sections of the flue system
should always be installed sloping towards the boiler, in
order to avoid condensate lying in the flue system.
The minimum gradient is 30mm/mtr. With the condensate
running back to the boiler the risk of ice forming at the
terminal is reduced.
