11. MAINTENANCE AND CLEANING
Before proceeding with any maintenance operation the boielr must be turned OFF and wait until has
reached the room temperature.
Empty the heating circuit only if absolutely necessary.
Periodically check the proper operation of the smoke exhausting devices and of the flue duct.
Do not perform any cleaning operation on the boiler using flammable liquids (gasoline, alcool, solvents,
etc.)
Do not leave flammable liquids or materials in the same room where the boiler is installed!
An accurate maintenance program will always mean fuel economy and safe operation.
11.1. Daily cleaning (wood operation)
Remove the residual ash layer using the special fitted tool supplied; let the ashes fall in the bottom
chamber and check that the upper part of the cast iron grate is free from any ash. This operation will
avoid plugging of the grate and, consequently, a defective boiler operation; will be avoided cast iron
bars overheating and a consequent quick wear.
Remove any ash from the catalyst zone.
11.2. Weekly cleaning
Wood only operation
Remove from any part of the wood chamber any residual combustion product.
Using the special brush supplied, clean the triangular smoke passages in the heat excanging zone
(lower door).
Empty the back part of the smoke chamber from any ash working through the side doors.
Check for plugged grate slots.
Pellet operation with burner
Remove from any part of the wood chamber any residual combustion product.
Using the special brush supplied clean the triangular smoke passages in the heat excanging zone
(lower door).
Empty the back part of the smoke chamber from any ash working through the side doors.
Opened the outdoor, take off the stainless steel grate (4) and, with a steel brush, take off the
combustion clinker.
WARNING: if, after 8-20 hours of continuous operation, on the grate (4) combustion buildups are found, the
pellet used is of poor quality, with a high loam or tree bark part, or other uncombustible materials.
These kinds of unsuitable materials cause a lot of firing and combustion problems if the grate (4) is not
cleaned frequently; we recommend using good quality and certified pellets only.
Clean the burner combustion area from flying ashes and clinkers.
Clean the photocell bull's eye (1).
Clean the flame bull's eye (7).
