6.2 Installing the displacement rods into the heat exchanger
The displacement rods improve the heat transmission in the heat exchanger and reduce the temperature of the exhaust gas,
thus improving the efficiency of the heating system. They are taken out to clean the heat exchanger tubes and then put back
in.
Insert the displacement rods into the heat exchanger tube with the thick end first. Push until they are flush with the bottom
of the tube. Tol/- 5 mm.
Remove the displacement rods with a pair of pliers, as shown below. The heat exchanger should be cleaned at the intervals
prescribed so that, on the one hand, performance and efficiency are maintained, and on the other, the displacement rods can
be easily removed.
