Viessmann VITORONDENS 200-T Technical Guide

■ Vitoladens 300-C: Via the ventilation air connector on top of the
boiler
■ Vitoladens 300-T, Vitorondens 200-T, 222-F: Direct on the burner
casing
■ Vitoladens 300-W and 333-F: By the annular gap between the flue
pipe and ventilation air inlet on the boiler flue connection of the Vito-
ladens.
1.4 Flue gas temperature protection
The following Viessmann balanced flue systems for balanced flue
operation are tested to the DVGW standard as a single technical unit
with the Vitoladens or Vitorondens 200-T up to 54 kW, as with gas
condensing boilers:
■ Vertical roof outlet (only Vitoladens 300-W and 333-F)
■ Separate ventilation air and flue gas routing
■ External routing through a coaxial pipe
If a different flue is used, ensure connection in accordance with the
guidelines for the approval of flue systems for low temperature flue
gas. For the Vitoladens, these are plastic flue pipes type B (max. per-
missible flue gas temperature 120 °C).
Features inside the equipment ensure that the max. permissible flue
gas temperature is not exceeded.
An additional flue gas high limit safety cut-out is therefore not
required.
1.5 Lightning protection
If a lightning protection system is installed, any metallic flue system
should be included in the lightning protection scheme.
