Yearly check
Cleaning the flue gas fan
Remove the fastening screws and extract the flue
gas fan to clean it.
Perform the operation with the utmost gentleness
in order not to bend the fan blades.
Cleaning the flue gas duct
Clean the flue gas exhaust system especially
near the "T" fittings, the elbows and any horizon
-
tal sections. It is required to check and remove
any deposited ash and soot before it obstructs
flue gas flow.
Cleaning the heat exchanger
Lift the upper hatch that covers the shell and tube
by unscrewing the screws. Extract the 16 springs
and clean with a brush the 16 pipes of the ex-
changer.
Cleaning may be performed after removing the
springs inserted in each pipe. The operation is
simple, extract the springs from the horizontal pin
they are secured to.
To perform the operation, the horizontal pin may
be extracted through a hole placed on the wall of
the stove structure.
The upper section of the heat exchanger is now
free from any encumbrance so it can be cleaned
perfectly.
Once a year it is recommended to also clean the
compartment above the exchanger. To perform
proper cleaning it is recommended to vacuum the
ash, remove all the horizontal joints with a screw-
driver, then vacuum the ash again.
Heat stove maintenance and cleaning
The operation may be completed by unscrewing
the stove wall with a screwdriver and extracting
the horizontal joints.
Following cleaning the upper compartment of
the exchange section, replace the upper closing
cover.
This cover must be closed with the normal screws
as well as with the ceramic fibre cord to assure
the stove is sealed tightly.
This general cleaning must be performed at the
end of the season in order to facilitate general re-
moval of all combustion residues without waiting
too long because with time and humidity these
residues might compact.
Check seal of ceramic fibre gaskets on the stove
door.
After that clean the flue gas exhaust system es
-
pecially near the "T" fittings and any horizontal
sections.
