SERVICE AND MAINTENANCE
Cleaning
1. Before cleaning the boiler, it is advisable first to heat it, preferably with softwood, in order
to make it easier to remove soot. Clean the boiler’s convection section 2-4 times per month
and whenever required.
2. Once the fire has gone out but the boiler is still hot, open the cleaning hatch on top and
brush/scrape it clean.
3. Open the cleaning hatch at the side and remove any loose incrustation with an ash scraper.
4. Open the firebox hatch, clean the grate and empty the ashbox into a fire-proof ash bucket.
N.B. The surface of the ash must never rise up to touch the grate. This prevents cooling of the grate
and will rapidly result in damage. For this reason too, the holes in the grate must be open.
Ensuring the tightness of the hatches
All pitch, etc. must be removed from the hatch seals and sealing surfaces. If leaks appear in the
hatches, these must be eliminated. This can be done by turning the locking pin cam to a diffe-
rent position. If this does not help, the seals must be changed.
