MD system description
Single-walled, metallic-sealing, stainless steel flue gas system
Single-walled, tapered-section, metallic-sealing, soot-fire-resistant, stainless steel flue gas system for chimney refurbishment.
The components are made of a high-alloy stainless steel resistant to intercrystalline corrosion. The smooth-walled, rigid stainless steel elements feature an outwardly tapering coupling sleeve and a bead to interrupt capillary action. The bead also helps improve stability. The tapered design means that the plug-in connections are metallically sealed. This makes the system suitable for both underpressure and overpressure operation and seals it against condensate.
The structure at a glance
for better protection against escaping flue gas and condensate and no blocking of the condensate drain:
- Metallic sealing – tapered plugging
- Cleaning apertures fitted with sealed high-temperature cover
- Condensate shell with DN50 connection (practical connection for HT pipe)
General information for planning the flue gas system
- All details of the flue gas system design must be agreed in advance with the responsible flue gas inspector.
- When planning and installing the flue gas system, pay careful attention to the planning documents and installation manuals for the flue gas system and pellet boiler.
- The long elements of the MD system cannot be shortened.
- The on-site design and installation of the flue gas system must comply with the applicable regulations and official requirements.
