Requirements Of Safety Equipment; Cleaning And Maintenance Of Boiler - Stropuva S7 Technical Passport Installation And Maintenance Instructions

When using fi rewood you must remove the ashes every month. When using peat and coal,
ash must be removed before each fi ring. Naturally some resin accumulates on insides of boi-
ler, amount of resin increases when fl ue draft is incorrect; when air gets in through bottom or
through bottom doors for ash removal (11) (fi g. 1); when at the time of burning fuel is added
constantly and air distributor with combustion chamber stabilizer is lifted; when fl ow of heated
water is too high.
If draft has decreased, openings between air heating chamber (4) (fi g. 1) and inner wall of
boiler must be inspected and cleaned. They can be cleaned with fl exible brush through inner
smoke opening (5) (fi g. 1) above fuel loading doors (8) (fi g. 1). It is most convenient to clean
through opening for smoke removal (5) (fi g. 1) (after dismantling the connection with fl ue) or
through special opening on the connection itself (fi g. 6).
Boiler will not become clogged up if heating system is correctly installed, fl ue is well
preserved and used according to instructions.
Air distributor with combustion chamber stabilizer (9) (fi g. 1) can scoop some ash when it is
lowered, so its openings sometimes need to be checked and cleaned.
Cord of lifting mechanism (12) (fi g. 1) must be oiled so that it wouldn't wear and distributor
with combustion chamber stabilizer (9) (fi g. 1) would be lifted more easily. We recommend oiling
the hooks for door closing.
Sometimes it needs to be checked if the doors seals uniformly. In order to make doors seal
uniformly, gasket needs to be changed or tab of lock needs to be adjusted.
Boiler room is a zone of increased hazard. Irresponsible behavior can lead to injuries, poisoning,
fi re, damage to boiler or heating system.
Safety requirements and warnings
1. Don't let the water in boiler reach the boiling
point.
Do not fi re the boiler when there is no water.
Don't let the pressure of system exceed 1,5 bar.
Don't let the water in the boiler or heating system
freeze.
2. Ventilation of boiler room is necessary.
3. Do not allow air in trough bottom door and do not
lignite the fuel from the bottom.
4. Do not store fuel in boiler ( after loading the
fi rewood it has to be ignited)
5. While boiler is burning do not lift the air distribu-
tor with combustion chamber stabilizer

8. REQUIREMENTS OF SAFETY EQUIPMENT

Consequences for not adhering to the safety requirements and
instructions
1. After water boils out, boiler will overheat and crack up. If tempera-
ture is rising in the boiler without known reason, immediately close
the top air supply valve, lift the air distributor with combustion cham-
ber stabilizer, set the water pump to maximum speed, open the door
while keeping your face away and load sand, dirt or other infl ammable
material.
2. Boiler operates badly.
3.Condesation will leak, you will use up more wood. Water in boiler
will start to boil and coal will fall out.
4. Firewood will ignite from leftover ember at the bottom and will burn
out uselessly while leaving condensate and raisins.
5.If you hit air distributor, which has softened from heat, against the
fi rewood you will bend it and if it will stick deeper into fuel its lifespan
will be reduced signifi cantly.
