16.1 SAFETY DRAIN VALVE
Cooling safety exchanger use:

Step 6./b
Vertical
primary air lead
Step 6./a
Side
primary air lead
Primary air cleaning
Please check and clean primary air pipes only, if necessary. Congestion can
appear when using wet wood or boiler runs in long term - low performance. Type
of primary air design is different for each boiler model.
Step 4:
Dismantle primary air separatory panel.
Step 5:
Use vacuum and scraper to clean primary leads and check cleanliness.
Step 6:
Only in special cases is possible to dismantle vertical primary air lead.
With boilers VIGAS 16, VIGAS 25 a VIGAS 40 side primary air lead,
also ( step 6/a, step 6/b).
Note:
It is necesary to use silicone heatproofe seal, when this action is
repeated.
Cooling safety exchanger with drain valve TS 131 provides
boiler protection against overheating due to power cut. By
forced circulation the pump and water flow in the central
heating will shut down. If you do not have option of
automatic gravity convection or minimum heat consumption
of 5 kW, boiler may be overheated. Drain valve TS 131 and
cooling exchanger will restrain boiler for overheating.
Assembly of drain valve TS 131:
Drain valve TS 131 screw in the boiler socket „1“ so it may
close water prior to boiler inlet. Safety exchanger must be
water free. Second socket „3“ pic., must be directed to
drainage. Thermal sensor insert into ½“socket, pic. „2“.
Warning:
Valve and thermal sensor assembly is necessary before
central heating system is filled with water.
The pressure of cooling water can not subordinate to power
supply.
It is adviced not loose ¾“ socket „2“ pic. Water leak can
appear. There is an aluminium ring „4“ under the insert „3“
to seal copper pipe „5“. If water leaks, tighten ¾“ insert „2“.
Operation rule:
Drain valve is regulated by hot water. If water temperature is 95 °C, valve opens. Water running from main
distributing source will absorb the temperature from boiler and prevent it from possible damage and
overheating. This boiler protection system complies with standards STN EN 303-5.
