15.1 Drain valve
Usage of safety cooling exchanger:
Safety cooling exchanger together with drain valve,
Honeywell TS 130, serves as boiler protection
against overheating in case of power failure. If
there is forced circulation, pump will be switched off
and water circulation in the system of central
heating stopped. If you have not ensured the
automatic transition into gravitation (self-flowing)
flow, or minimum heat consumption, 5 kW, boiler
may be overheated.
Drain valve Honeywell TS 130, together with cooling
exchanger are preventing to boiler overheating.
Assembly of drain valve TS 130:
On boiler socket “1” screw TS 130 valve on one of ¾“ boiler coupling so
that TS 130
might close water prior flowing to boiler.
Safety exchanger must be without water. The
second coupling “3” will lead to canalization. Screw thermal sensor onto ½“ “2”.
Warning:
- Assemble valve and thermal sensor prior filling the central
heating system with water.
- Pressure of the cooling water can not be dependent on electrical
voltage.
- Do not loose ¾“ socket „2“ when assembling, watere leak
possibilty. Under the socket is aluminium ring „4“ with sealing „3“,
that seals copper pipe „1“ in socket „5“.
If water leak, draw close ¾“ socket „2“.
Principle of operation:
Drain valve is regulated by hot water. If hot water temperature is 95
°
C, valve will open.
Water running from water main absorbs temperature from boiler and thus it prevents
overheating or boiler damage.
The system of boiler protection correspond with the standard, EN 303/5.
