As an FYI to those who are new to gasification boilers and/ or maintenance of such systems:
You can look forward to a remarkable absence of creosote in the chimney and any flue pipe between boiler and chimney-
BUT
Be sure to check any horizontal flue runs (yes I know that they are to be avoided/ minimized/ pitched with a rise) for buildup of fly ash.
I have a horizontal run between my boiler and chimney (it was unavoidable given old farmhouse basement geometry...) and each season of burning manages to fill that flue pipe nearly half full with an accumulation of fly ash.
