:
•
Whether the installation conforms with the design;
•
Whether the boiler has been filled in and is under pressure , and whether there are any leakage in the
heating system;
•
Connection to the chimney - connection must be approved by an authorized chimney sweep ( chimney
inspection);
•
Functioning of the heating controls.
Please note
The service technician must show the user how to control the boiler and enter the date when the boiler
boiler was put into service into the Warranty Certificate.
Filling up and draining the heating system
The system can only been filled up or topped up with water which meets the parameters specified by EN
standarts. The water must be clear, colourless, free of suspended particles, oil and chemically corrosive
substances, and must not be acidic ( pH factor must be greater than 7.2 ). First of all, the heating system
must be thoroughly flushed and all dirt washed out.
Please note
Water in system must not be reduced or put out unless the boilers is in service or under freezing danger.
Against freezing anti-freeze liquid can be added in to system water at the rate of % 15.
Please note
The failure to meet this requirement may lead to the heat exchanger getting clogged up, and the cast iron
block may crack as a result.
During the heating season a constant volume of water must be maintained inside the heating system

When topping up water, care must be taken that no air is sucked into the system. Water must never be
let out of the boiler or the heating system, unless it is absolutely essential, such as before repairs, etc.
Draining water and refilling the system with new water increases the risk of corrosion and formation of
incrustation.
Please note
Filling or topping up water to the heating system must always be done with the boiler cold or cooled down;
otherwise the boiler segments may crack !
Operation and controls
Starting a fire
Check on the manometer whether there is enough water in the heating system. Open the shutting
valve between the boiler and the heating system. Spread paper on top of the clean stoker and then enough
finely chopped wood. Open the flue flap in the chimney adapter and shut the stoking door. Light the paper
through the open ashtray door and fully open the regulating flap in the ashtray door. The fire has caught up
enough, stoke a layer of main fuel on top of the burning firewood. When the fire is powerful enough, stoke
more fuel right up to the bottom edge of the stoking door and level it into.
