Introduction

• The single-wall cascade system is meant for collective evacuation of flue for several boilers which are installed in cascade. The combustion air usually comes from the boiler room.
• The flue pipes are made in PP.
• The system has a H1 tightness class which enables operation with positive pressure. This reduces the required diameters compared to a negative pressure system.

Remark

• Cascade installations can be, theoretically, combined with several flue systems. The chosen system picture is a typical application and is meant as example.

Features and benefits

• The PP pipes can be easily cut to adjust the length
• Optimal flexibility combined with maximum robustness
• Chimney calculations possible on request
• Lightweight; easy to handle and easy to shorten
• Plastic materials; less risk of injuries as result of sharp edges
• Transparent material; easy to inspect during installation
• Non-return valves available
