The most important thing in any chimney maintenance program is to make sure the chimney is swept regularly. Check out our article: Chimney cleaning for wood and multi-fuel stoves .
Make sure that the wood -burning or multi -fuel Profiwerkzeug stove has been installed correctly. You may also want to read our article: Installing wood and multi-fuel stoves .
The second procedure in the kiln maintenance program is to check the kiln for defective seals that are causing excess air to be drawn into the lit combustion chamber, resulting in lack of control of the burning fuel, poor combustion and, under certain conditions, leakage of gas from the furnace. This is best done at the beginning or end of each heating season, or if at any time the stove’s firing is becoming more difficult to control.
Before you start, please make a quick sketch of the stove.
Simply shut off any air intakes on the lit stove, put on a pair of heat-resistant gloves, and take a cigarette lighter or gas stovetop lighter with you. Slowly move the lit cigarette lighter or gas stove lighter around the oven door where it seals against the door frame. It is best to make sure that there are no large drafts in the room at this time. If the lighter flame is drawn anywhere towards the door seals, you will know immediately that excess air is being drawn into the combustion chamber at that point. Note where leaks are on the sketch and continue around the glass where it meets the door to ensure there are no leaks between the glass and the glass cable seal. Some cast iron multi -fuel and wood- burning stoves are bolted together by a system that uses iron rods that run through the stove corners from the top of the stove top through the insides of the stove to the bottom of the base plate where they are bolted… Another method used is the lugs and bolts connected to each other inside the wood -burning or multi -fuel stove . All the cast iron plates 6 in total, the top, bottom, front, back and two sides usually have grooves so that they are well connected before they are bolted together. The grooves are usually lined with fire cement at the time of manufacture to ensure a good airtight seal. Slowly run the lighter along the joints where all the plates meet both vertically and horizontally around the stove, again noticing any point where the flame is drawn towards the stove. Done, you now know if your stove is still working as it was intended or if it has developed a few leaks due to wear and tear.
The next step in the furnace maintenance program is to fix any leaks found as soon as possible. Let the wood -burning or multi -fuel stove go out and do not light it again until the leaks are fixed. Poor sealing here can, under certain conditions, allow toxic, undetectable gases Bosch such as carbon monoxide to enter the exhaust plenums if there is poor combustion in the furnace. This is a particular problem when burning smokeless or fossil fuels in a multi -fuel furnace . I am happy to postpone the rest of the stove maintenance until the end of the heating season, for reasons that will be explained later.
