Dewing and tarring
When starting fire in a cold boiler, water condensates on the walls and runs down into the ash compartment,
which may make an impression that the boiler is leaking. This dewing will disappear after the astray has
settled on the boilers inside walls. When running the boiler with low water temperature usually below 65°C,
or when using damp fuel water condensates in combustion gases and the condensate runs down the or when using damp fuel, water condensates in combustion gases and the condensate runs down the
boiler’s cold walls. Low temperature heating also reduces the chimney life. Therefore it is recommended to
equip the boiler with for instance a four-way blending valve which will ensure that the temperature of return
water does not drop below 50°C. Boiler tarring occurs under similar conditions ( lack of combustion air, the
boiler is choking ). To prevent dewing and tarring, we recommend you run the boiler at temperatures higher
than 65 °C and choose a boiler to match the required heating system output. An oversized boiler suffers
unnecessarily, because it has to be run at low temperatures.
Boiler shutdown
We do not recommend that you try to speed up the boiler combustion process.The fuel must burn completely
on its own on the stoker.
Short term shutdown
After shutting the boiler down, clean it, remove all combustion residuals,empty the ashtray,clean the stoking
door contact surfaces and the ash compartment, and then shut the boiler’s stoking door and ash
compartment door.
Long term shutdown
When shutting the boiler down for a protracted period of time ( heating season end ), the boiler must be
thoroughly cleaned from all soot and ash sediments, in which dampness accumulates and causes
excessive corrosion of the boiler body.
Important information
• The boiler may only be operated by an adult person familiar with these Operating Instructions.
• Shut the boiler down every time there are any ( even temporary ) flammable or explosive fumes present on
the premises from which combustion air is supplied to the boiler ( e.g. From paint when painting, laying and
spraying molten substances, from gas leakage, etc.).
• It is forbidden to light the boiler with explosive substances.
• It is forbidden to overheat the boiler.
• At the end of the heating season the boiler, flue and flue adapter, must be thoroughly cleaned. Lubricate
all hinges the flue flap mechanism and other moving all hinges, the flue flap mechanism and other moving.
Boilers maintenance are made in three programs.Daily (in everyday use ),periodic and yearly.
Maintenance
Daily Controls
These are the processes that the user must apply every day in season of everyday use. The combustion chamber and
fittings must be checked.Combustion products in the chamber must be cleaned and the ash tank must be discharge.
