hergom E-20 N Installation, Use And Maintenance Instructions page 34

If a masonry chimney is used instead of metal pipes, we recommend the installation of a
hatch for regular cleaning and inspection. This hatch is normally located in the lowest part of
the chimney (for example in the basement of a house).
If the masonry chimney was built without a hatch or clearing door, inspections should be
performed from the connection point of the stove and the chimney.
1.3.2- CHIMNEY CLEANING
Use the appropriate anti-soot chimney brushes for
the most effective cleaning of the chimney.
The brushes should be adjusted as far as possible
to the diameter of the chimney.
To delay the need for general cleaning, we
recommend the regular use of the HERGÓM Anti-
soot product, which is available from any of our
suppliers.
Regular Inspections
Carry out the following inspections within the
recommended time limits.
Monthly:
 A visual inspection of the creosote level of
the chimney and its connector is recommended,
depending on the use of the appliance.
At the end of all seasons:
 Dismantle
thoroughly clean it.
 Replace any pipes that show signs of
excessive wear or deterioration.
 Inspect and, if necessary, clean and repair
the chimney.
1.3.3- CREOSOTE
Slow burning wood produces tar and other organic
vapours, which combine with atmosphere moisture
to form creosote. These creosote vapours may
condense if the chimney walls are cold. Extremely
hot fires may occur if the creosote ignites. Any build-
up of creosote must be eliminated immediately. As
the build-up of creosote depends on many
variables, it is extremely difficult to predict exactly
when the chimney should be cleaned. Visual
inspection is the safest way of checking whether your chimney is creosote free. For this
reason, we recommend that the installations are easily accessible for inspection.
To prevent the possibility of a fire, the venting system should be correctly installed.
Immediately replace any component that is rusted, cracked or broken.
