4.13 Flue pressure switch
Flue pressure switch is a safety device designed to turn off the burner in
case of block vent (for example due to obstruction of condensate drain).
The silicon pipe is connected on one end to the “+” port of pressure
switch (Fig. 20), and on the other end to the bottom of the heat exchanger
(Fig. 21).
