It is more appropriate to make the cleaning of the external surface with the warm water and soap instead of chemicals.

Don’t open the covers or leave them open when there is a burning flame.

Do not put any fuels in the bunker other than the one recommended by the manufacturing company. (liquid or other flammable substances) Never remove the bunker sieve.

Pay attention for the fuel to be clean. Wet coal and the bolts, screws, stones etc. will damage the stocker mechanism.

Never use your boilers in closed retort connected assemblies. Warn your assembler.

Do not approach when the reducer and helix are operating and don’t throw foreign objects (e.g. stone)

In agitated storage tanks, the reducer shouldn’t be operated before the flammable substances that are put on the coal (wood, kindling, oily cloth) start to glow, otherwise the ash falls inside the helix section and causes clogging.

The fire should be kept on top of the burning chamber that we name as basket. The fire shouldn’t burn inside the basket, otherwise it will cause damage in the boiler by melting the cast material and helix.

The coal level in the bunker should be at least 20 cm above the floor, otherwise the risk of smoke coming from the bunker arises.

Please pay attention to pump water in the boiler when the boiler is in cold state.

When the water is being pumped inside the boiler, make the hose flow free for a while. The air inside the hose will cause damage to the system.

Do not lose the usage manual, we recommend you to make use of it when needed.

Following the steps stated in the manual will prolong the efficiency and life of your boiler.

Use your boiler in compliance with the instructions given by our authorized service when it was being delivered to you running with correct settings. Do not adjust its settings without informing the service.

Upon the correct installation of the device and water injection to the fixture, Yağmur Authorized Service should be informed and the first run of the device should be requested.

Do not deaerate the fixture when the pump is active.

Please buy your fuel before calling the service for the first run.



Please do not forget that the quality of the fuel you use will affect the boiler efficiency, burning quality, the amount of ash, cleaning time and the amount of the fuel you consume. High calorie coal can cause damage to cast and sheet metal. Do not use powedered, wet or coking coal.



The device should not be installed in places in contact with water or humid locations.

If the device is installed in outdoor places, adequate protection should be provided. (it should be protected against external conditions like rain or sunlight) The device should be mounted in places where it can receive enough ventilation for burning.

The device should be assembled in such a way that is available for service operation.

The assembler company should mount assemble the device according to all the instructions and warnings given in this manual. Otherwise the assembler company will be liable for problems that may arise.

Any connection exposed to the external environment like fixtures, hot water and flue should be isolated.

Flue is one of the most important elements of the system. An efficient burning shouldn’t be expected in a place without a good flue.

The fixture should start with the external dimensions of the device and it should be applied shrinking gradually but the fixture dimensions shouldn’t be less than ¾” until the last radiator set.

Water inlets and outlets of radiators should be cross- connected.

An air relief cock should be installed in each radiator set.

An appropriate expansion tank should be mounted on top of the fixture.

Ball valves should be mounted on the send and return lines of the device.

Circulation pump should be mounted in a way that it pumps into the fixture.

Insulation of flue connections should be ensured.

Flue connections should be made in suitable dimensions with the output dimensions of the device and the section of flue shouldn’t be narrowed down.

It is crucial to establish the ground connection of the device.

The device should not be exposed to voltage fluctuations. YAĞMUR TEKNİK shall not be liable for the harm that may be caused on humans, animals or objects due to the failure to establish proper electrical and ground connections. If the boiler is being mounted in a confined space, there should be a ventilation window.

The boiler should be mounted on its scale and should stand on a level surface. In central systems, it should sit on a pedestal with a minimum height of 25cm.

Do not, under any circumstances, use your boiler with the installation connected with closed expansion. Warn your assembler. Systems with closed expansion connections are not covered under warranty. The device is considered out of warranty. Yağmur Teknik shall not be held liable for the problems arising from closed expansion.

There should be no valves, check valves or filters installed on the pipes between the boiler and the expansion.

During the installation of the stoker fired heating boilers, a space should be left for the disassembly of reducer or helix. In order to achieve this, the installation should be made in a way that allows the service to intervene.
