Why is it necessary to seal the firebox door?
Thermal insulation of the combustion chamber door and the boiler increases the degree of fuel utilization. This is the main reason why it is important to seal the firebox door once every 2 or 3 years. Thanks to special advanced solutions for controlling the combustion process and having horizontal and vertical drafts, greater efficiency in use is possible. Proper selection of the damper for the primary air supply to the boiler combustion chamber results in better fuel combustion. The air intake on the upper door is designed for burning wood, and the lower flap for using coal, i.e. a combination of wood and coal.
What preparations should be made for sealing the firebox door?
After you have ascertained which seals are installed in your furnace, it is important to check the condition of the sealing cables. In most cases, you can tell if the cable seal is intact by looking at it, but you should still do a simple test to make sure it is. You can check the strength of the door by jamming a piece of paper in the door and trying to move it or pull it out. This must not be possible at any point of the seal. You can check if the stove is drawing fake air by placing a stick of incense on the edge of the glass when the stove is hot and the air supply is closed. If there are worn seals, it”s time to seal the firebox door. To do this, you must first remove the defective gaskets so that you can determine the exact dimensions of the new gaskets.
How to properly use a solid fuel stove?
Firebox door sealing Before the first firing, it is necessary to wipe all surfaces of the stove with a dry cloth, to remove dust, oil and impurities from the stove and oven, in order to avoid their burning and the creation of unpleasant odors and smoke. When burning for the first time, smoke and an unpleasant smell are created, especially from the surface of the stove, but also from other parts that are protected with heat-resistant paint. This is a normal phenomenon, because at temperatures above 250 °C, the color stabilizes during the first firing. Therefore, ventilate the room. Over time, it is necessary to service the parts that wear out at this temperature. This primarily applies to asbestos gaskets, so it is necessary to replace them after some time. Sealing the firebox door improves the function of the stove itself and protects the environment from harmful gases and unpleasant odors.
Glass replacement for solid fuel stoves
In all stoves, the glass breaks mainly due to carelessness, and then problems arise when we want to replace them because, except for the “Alfa” stoves and stoves, original glass is hard to find. Avoid installing sheet metal because it bends, lets air in and accelerates combustion, and it”s more beautiful when you can see the fire. The simplest thing is to buy custom-made reinforced glass, which cracks but does not break due to the wire reinforcement. This kind of repair can last for two or three heating seasons until you find the original part.
Managing the operation of solid fuel stoves
It is recommended that the amount of fuel be halved and gradually warmed up when using the stove for the first time. This is for the purpose of checking operation and running in. The maximum amount of wood for safe work is 2.5 kg. The firebox door should only be opened when necessary, when a new quantity of wood is added. The next amount of wood is inserted only after the previous amount has burned. Do not allow clogging of the roast with ash and unburned fuel. Clean the roast. Open the door slowly, never by pulling it suddenly, allowing equalization of the pressure in the firebox and the room. This prevents the exit of smoke and flames from the firebox. The combustion chamber door must be closed during the operation of the stove.
What are the advantages of new seals?
The stove door seal basically has two functions: on the one hand, it should keep toxic exhaust gases out of the living space, and on the other hand, ensure that false air does not enter the combustion chamber. The extra air creates more heat, the burning items burn much faster, and the wear and tear on certain parts increases dramatically. The new seal reduces fuel consumption and reduces wear on other components. If you are not sure whether it is time to service and seal your stove, contact the masters in this field.
