Points to watch during use
- Clean the outer surfaces with warm water and soap; do not use sharp tools or chemicals.
- Do not open the doors while the fire is burning, and do not leave them open.
- Do not put anything other than the fuel recommended by the manufacturer into the hopper, whether liquids or other combustible material, and never remove the hopper screen.
- Make sure the fuel is clean; wet coal and foreign objects such as bolts, screws and stones damage the stoker mechanism.
- Never run the boiler on an installation with a closed expansion tank.
- Keep your hands away from the gearbox and auger while they are running, and never drop foreign objects in.
- On boilers with an agitator, do not start the gearbox at first lighting until the kindling placed on the coal, such as wood, firelighters or oily cloth, has turned to embers; unburnt material falls into the ash auger and jams it.
- The fire must stay on top of the burner pot; a fire burning inside the pot melts the cast iron and the auger.
- The coal level in the hopper must stay at least 20 cm above the base, otherwise smoke may come back through the hopper.
- Fill the boiler with water only while it is cold, and let the hose run to waste for a while first.
- Follow the user manual and do not change settings without telling the service team.
- Contact the nearest authorised Yağmur Teknik service for commissioning, and buy your fuel before you call them.
- Do not bleed the system while the pump is running.
Fuel
Fuel quality has a direct effect on boiler efficiency, combustion quality, ash volume and cleaning intervals. Test a sample before you buy. Coal with a very high calorific value can damage cast iron and steel parts. Do not use coal dust, wet coal or coke.
Installation information
- The unit must not be installed where it can come into contact with water or in very damp places; outdoors it needs a sheltered area.
- Choose a room where the unit can draw enough air for proper combustion and where it can be operated and serviced.
- The installer must follow every instruction and warning in the manual.
- Pipework, hot water lines and flue connections that run outdoors must be insulated; without a good flue there is no efficiency.
- Pipework must reduce gradually and must not drop below 3/4″ before the last radiator group; radiator connections must be diagonal and every group needs a bleed valve.
- Fit an expansion tank sized for the capacity at the highest point of the system, ball valves on the flow and return lines, and the circulation pump on the boiler so that it pumps into the system.
- Flue connections must be gas-tight, made to the outlet dimensions of the unit and never narrowed.
- An earth connection is essential, and the unit must not be exposed to voltage fluctuations.
- Indoor installations need a ventilation opening; the boiler must sit level on a flat floor, and in central systems on a plinth at least 25 cm high.
- The safety pipes between the boiler and the expansion tank must carry no valves, check valves or filters.
- Leave room during installation so the gearbox and auger can be removed, and mount the unit so the service team can work on it.
Closed expansion systems are not covered by the warranty. Systems fitted with a closed expansion tank are never covered by the warranty, and Yağmur Teknik cannot be held responsible for problems arising from them. The manufacturer also accepts no responsibility for damage caused by electrical or earthing connections that do not follow the rules.
