Maintenance
Proper maintenance of the boiler is essential for reliable, efficient and safe operation. This will also
contribute to longer boiler service life. There are specific maintenance guidelines to follow during the
heating season, and others to follow during the off-season.
Standard Cleaning Tools
These are the tools supplied with a boiler. Note that the EKO Super 1 model is not shipped with a
heat exchanger tube cleaner.

Fan Maintenance
The blower fan (or fans) is an essential part of boiler operation, and should be kept clean. It is advis-
able to monitor the fan’s condition and clean it from time to time with a soft bristle brush.
Warning!
Operating the boiler with the bottom door open can cause the blower fan to overheat.
Routine Cleaning During the Heating Season
Ashes produced in the firebox during boiler operation fall down through the nozzle into the lower gas-
ification chamber. During fuel loading, any ash remaining in the upper combustion chamber can be
pushed down through the nozzle with the tool provided, using care not to damage the nozzle. Accu-
mulated ash should be cleaned out of the lower chamber as needed, typically every 3-5 days.
EKO Super 1 Model Heat Exchanger Tubes
The EKO Super 1 model boilers are equipped with a lever-operated heat exchanger cleaning device
consisting of spiral steel elements (turbulators) that clean the tubes as they are moved up and down.
Vigorously moving the handle back and forth either before or after each fuel loading will help assure
that the heat exchanger does not become clogged with creosote, soot or ash. The moving turbulators
knock any residue that has accumulated in the tubes back down into the ash pit/secondary combus-
tion chamber, where it can be cleaned out with the ashes. The lever should not be operated while the
chimney bypass damper is open.
Cleaning the EKO Standard Model Heat Exchanger Tubes
On the EKO standard models, the heat exchanger tubes should be manually cleaned every two
weeks using the following procedure. (Note: The bi-weekly cleaning routine described as follows is
not necessary with the Super 1 models).
