NOTE: Filling installation with water when boiler is in use, especially if it is very
hot is strictly forbidden, as boiler’s damage or fracture may be caused.
Once heating season is over do not get rid of water from heating installation and boiler.
When required, water may be let of through blowdown connection to a drain once it is cooled
down.

FIRING UP A BOILER
Firing up a fuel in boiler should be started when checked if heating installation is filled with
water, and water is not frozen. It should also be checked, if water is not leaking through
thread fittings on boiler. Do not forget to heat the chimney prior to the firs startup.
Before the fire up, smoke throttle in the smoke conduit should be fully opened, as
well as ash box and furnace door, likewise the fuel charge.
The operation should be performed slowly, using crimpled pieces of paper and wood. Then
thin layer of coal is applied. Once a coal is glowing, the ash box and furnace door must be
closed. Open fuel charge door and fill the combustion chamber with fuel reaching the level of
the upper door, close the fuel charge door and switch on controller. Set the required
temperature on the controller.
BOILER SAS NWT IS THE LOWER COMBUSTION TYPE
AND SHOULD NOT BE FIRED UP FROM THE TOP!
During fire up process the boiler should be monitored until it gets feeding water
temperature of 45°C. It is important, as varying fuel quality may cause the boiler to
go out.
In case of fire in boiler went out during fire up operation a furnace must be cleaned,
boiler’s should be ventilated and fire up should start again.
During the process a smoking or sweating of boiler may occur. Once boiler and chimney duct
get hot, those adverse phenomena should go away.
NOTE: Person operating the boiler should know that some of boiler’s areas are
hot, therefore protective gloves should be worn! The same applies to protective goggles.
