Type C 43 Common Vented Flue Systems In Multi Floor Buildings; C 53 (Twin Pipe) Flue Systems - Lochinvar ECOKNIGHT EKW116CE Installation, Commissioning, Maintenance And User Instructions

TYPE C COMMON VENTED FLUE SYSTEMS IN MULTI FLOOR BUILDINGS
43
This appliance can operate on a U-Duct common flue system. The maximum lengths for the interconnecting flue can be found in
Section 10.2.
Only use a C43 venting system when the common duct is a natural draught chimney. The
common duct is part of the building, not a part of the system.
Concrete components of the U-Duct must meet the requirements of BS EN 1858.
10.17.1
CONDENSATE DRAIN
Condensate can flow back to the appliance; this will travel through the heat exchanger into the condensate drain via the trap.If the
flue system rises at an angle of at least 3 (50mm per metre), no additional condensate drain will be required. Failure to provide an
adequate rise in the flue system may lead to pooling of condensate, which may lead to premature failure of the flue system.
