12.1 Adjusting power rating
On MEco pellet boilers the effective heat exchanger area can be changed within a unti range. This involves opening or
closing the heat exchanger tubes. The power rating of the pellet boiler is adjusted as a result. MEco supplies the pellet
boilers in one type group with the power rating shown below. If the condition as shipped is different from the power rating
on the data plate supplied, then the service technician must adjust the power rating before starting up for the first time.
12.1.1 Installing the turbulators and closure plugs
The heat exchanger in the pellet boiler has between 12 and 36 heat exchanger tubes, depending on the size of the
boiler. Springs are installed inside the heat exchanger tubes to clean the tubes as well as act as turbulators.
Increasing the boiler power rating
1. Remove the closure plugs from the ends of the heat exchanger tubes.
2. Insert the turbulators supplied into the heat exchanger tubes.
3. Hook the turbulators onto the ring of the cleaning system.
Reducing the boiler power rating
1. Unhook the turbulators from the ring of the cleaning system.
2. Remove the cleaning springs/turbulators from the heat exchanger tubes.
3. Close off the heat exchanger tubes using the closure plugs supplied.
