▶ Screw the LWCO as far as possible into LWCO adapter located in the
boiler accessory kit. Follow the Hydrolevel Safgard 1100
instructions.
Fig. 20 Installing a LWCO device - LWCO adapter
▶ Push the adapter with the LWCO onto the pipe (step 1) and secure
with the clip (step 2).
Fig. 21 Installing a LWCO device – securing with a clip
▶ Connect the wires of the LWCO ( chapter 6.4, page 46).
5.8 Connecting flue gas accessories
Optional vent systems are:
• Twin pipe PVC / CPVC 2" / 3"
• Twin pipe PP 3" (80 mm) (M&G DuraVent PolyPro GreenVent system)
• Concentric PP 3" / 5" (80/125 mm) (M&G DuraVent PolyPro
GreenVent system)
In case of using the twin pipe adaptor:
▶ Install the vent flange and gasket with the screws enclosed.

[3] Screws
▶ Insert the flue gas adapter as far as it will go into the vent flange and
align it.

▶ Tighten the screws.
The LWCO is positioned upright for technical reasons.
Tests have shown that all air will bleed from the pipe
during commissioning and full functionality is
established.
If fault d3 is displayed when commissioning the boiler,
purge the boiler properly and check the boiler water
pressure.
