DHW Production Kit Installation
(continued)
Electrical connection
1.
Insert plug ”X7” of the DHW tank
temperature sensor into terminal
”X7” of the control unit.
Condensate connection
Discharge tubing
Flexible discharge tubing
Siphon trap
The Vitodens 200 boiler comes with a
built-in condensate trap. An external
trap is not required when connecting
the field drain to flexible discharge
tubing. Discharge tubing (field supplied)
must be of 1” diameter. Use CPVC,
PVC or other material approved by
codes listed below.
The drain pipe and fittings must
conform to ANSI standards and ASTM
D1785 or D2846. CPVC or PVC
cement and primer must conform to
ASTM D2564 or F493. In Canada use
CSA or ULC listed schedule 40 CPVC
or PVC drain pipe, fittings and cement.
If the condensate outlet of the
Vitodens 200 boiler is lower than the
drain, a condensate pump must be
installed. Select a pump which is
approved for condensing boiler
applications. To avoid condensate
spillage, select a pump with an
overflow switch. The drain connection
must terminate into an open or vented
drain as close to the boiler as possible
to prevent siphoning of the boiler drain.
1.
Install the condensate drain pipe
with a suitable gradient.
2.
Discharge condensate from the
boiler into the drainage system,
either directly or (if required) via a
neutralization unit (accessory).
Installation Instructions of
Neutralization Unit
(if applicable)
Pipe ventilation must take place
between the siphon trap and the
neutralization unit (if applicable).
Do not connect the drain pipe from any
other appliance, such as water softener
backwash pipe, to Vitodens
condensate drain pipe.
