CLEANING the BOILER
Before applying mentioned services to the boiler; electric must be cut off from
the main switch, fuel valves must be closed, control panel and the burner must
be protected for avoiding any possible damage.
Smoke Channels Cleaning
Because of the soot layer on heating surfaces, 100 °C increase on flue temperature
brings out a %5 decrease on efficiency. By pulling out the M16 screws and
stamps on the 4 hinges which connects door to the front section, open the
burner door. Clean the burning room, take turbulators out and clean horizontal
smoke channels (2nd and 3rd pass). Than clean the turbulator and put them in
to the channels. Close the burner door strictly.In this cleaning operation soot
layer may occur in flue area.This soot particules can be cleaned by seperating
horizontal smoke channels from boiler flue. After this operation these two must
be connected again and must be tested for leakage.
The time period for cleaning service is variable according to the fuel type of the
boiler and period of use.
In boiler cleaning operation ceramic ropes that isolate front door with front section
and flue with back section must be controlled and must be renewed if needed.
