Other equipment, i.e. thermal outflow protection, safety valve, check valve and cleaning funnel must be accessible
after the installation is finished. Since for functional test the drain must be visible, the drain funnel should be used!
Figure: Connection of safety temperature limiting device
Minimum supply pressure for safety temperature limiting device: 2 bar
The connection must not be isolated (closed) manually.
1. Pressure regulating valve (only for connection to water supply with pressure above 6 bars).
2. Filter.
3. Check (non-return) valve.
4. Drain funnel.
5. Thermal outflow protecting valve (opens at temperature of 95 - 98 ºC), i.e. type SYR 3065.
6. Safety valve.
7. Cleaning funnel.
8. Thermal outflow protection sensor (temperature-controlled valve).
9. Connector for connecting the thermal outflow protection sensor.
Flue gas ducts should be built in accordance with currently valid
regulations.
Negative pressure in the chimney should be maintained at the level
specified in the Table. Chimney diameter can be selected using the graph
below.
The chimney diameter must not be less than the diameter of flue gas
connecting duct.
