4.9 Flue gas connection

Flue gas lines approved by planning law
The WTC is equipped with a concentric flue gas
connection Ø 125/80 located at the top of the unit. The
flue gases should be extracted via temperature and
corrosion resistant flue gas duct:
• in vertical ducting
• via external wall connections
• for roof heating centres with vertical flue gas duct
• air-flue gas chimney
The combustion air can be introduced:
• from the boiler room (room air dependent operation)
• by concentric pipe systems
(room air independent operation)
• by non-closing supply air ducts
Only CE certificated or locally tested and approved flue
gas systems must be used.
The Weishaupt Flue gas - air - system WAL-PP,
see installation and operating manual WAL-PP, offers
approved kits and individual components.
The flue gas duct must be gas tight.
Carry out soundness test.
Note: If a plastic flue gas system is connected,
which is approved for flue gas temperatures
up to 80°C, the maximum flue gas
temperature must be set to 80°C. Use
parameter P33 (see Ch. 6.3.3). The
Weishaupt flue gas-air system WAL-PP is
approved for temperatures up to 120°C.
