INSTALLATION, OPERATION AND MAINTENANCE MANUAL

Putting the boiler into service
Checking the boiler before turning it on
Before putting the boiler into operation, the service technician must check:
■
Whether the installation conforms with the design;
■
Whether the boiler has been filled in and is under pressure, and whether there are any leakages in the heating system;
■
Connection to the chimney – connection must be approved by an authorized chimney sweep (chimney inspection); and
■
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 the 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 in to provide an even layer throughout the entire boiler
depth. If the fuel suddenly turns into dark red blaze, open partially the secondary air supply rosette in the stoking door. When the flame
turns yellow, shut the secondary air supply rosette again. When the boiler has reached the required output, it is suitable to partially
shut the flue thrust flap to prevent heat from unnecessarily escaping into the chimney.
■
Do not start the boiler without connecting the boiler to the chimney.
■
Control chimney connections before starting the boiler.
■
Adjust the chimney blow as requested level. If chimney blow is under mentioned levels try not to
use the boiler.
