No, check local codes and installation instructions for the furnace.
Yes you can get a high wind cap for the vent.
To seal a gas flue from a furnace, first ensure the flue is properly disconnected from the furnace. Use high-temperature silicone sealant or a metal flue cap to cover the opening, ensuring it is airtight to prevent gas leaks. Additionally, inspect the area for any cracks or gaps and seal them with appropriate materials, such as metal tape or a chimney cap, to ensure proper sealing and safety. Always follow local building codes and regulations for gas appliances.
Chimneys were invented during the 12th century in Northern Europe, though we do not know who invented them, or precisely where. The oldest known example of a chimney dates from the year 1185. Prior to the invention of the chimney, smoke was vented in various ways. One was to have a hole in the roof, possibly with a vent cover called a louver to keep rain out. Another was to vent through window-like holes high in the walls, possibly with louvers to keep birds and bats out. Another way, used in castle and monastery kitchens, was merely to have very large, high windows. There was a thing called a smoke canopy, which gathered the smoke and vented it through the roof or a wall. A hearth that was situated against a stone wall, with a smoke canopy over it, looked rather like a fireplace, such as would have a chimney, even though no chimney existed. There is a link below to a question on smoke canopies. There is also a link to the history section of an article on chimneys, as well as a link to a picture of a great hall of the Late Middle Ages, with the hearth in the middle of the room.

Yes it can be shortened, making sure that the top of the vent is at least one meter above the highest point of the roof.
Yes you can get a high wind cap for the vent.

The best practices for high efficiency furnace venting include proper installation by a professional, regular maintenance to prevent blockages, ensuring proper vent sizing and clearances, and using high-quality vent materials to prevent corrosion. These practices help ensure optimal performance and safety of the furnace.
To properly vent a high efficiency furnace through a wall, you should consult the manufacturer's guidelines for specific instructions. Typically, this involves installing a vent pipe that extends through the wall to the outside, ensuring proper clearance and sealing any gaps to prevent leaks. It is important to follow local building codes and regulations to ensure safe and efficient venting of the furnace.
The best practices for installing a roof vent for a gas furnace include ensuring proper ventilation, following manufacturer guidelines, using high-quality materials, and hiring a professional installer to ensure safety and efficiency.
While it's not 100% accurate to say that you can convert a low-efficiency furnace to a high-efficiency furnace, there are things you can do to improve the accuracy of your existing furnace. You can approach this in two ways: retrofitting your old furnace with new equipment or taking steps at home to improve your efficiency.Retrofitting Your FurnaceRetrofitting your furnace involves adding new components to your old system. When you are considering retrofitting your existing furnace with new equipment, it's important to consider whether or not the cost of the retrofit will be worth it. This will depend on when you think you're going to replace the furnace (after all, all the retrofits in the world won't extend your furnace life forever). The most common types of retrofits are: Vent dampers - a vent damper prevents the loss of heat from the chimney by closing off the vent when the furnace isn't firing. Installing vent dampers is more common with steam boilers than furnaces.Intermittent ignition devices - many older furnaces have a pilot light that is on constantly. An intermittent ignition device will light the pilot only when necessary, saving you a little in fuel costs.Derating gas burners - while not always allowed by building codes, it is possible to reduce the heating capacity of an oversized furnace system to make it more efficient. This should only be performed by a qualified HVAC technician, as it can be quite complicated.Improving Furnace EfficiencyIf the thought of retrofitting your furnace with upgrades that may not pay off in the long run is a little upsetting, there are steps you can take at home to improve the efficiency of your furnace. Change the filters - this is the easiest way to improve your furnace efficiency. Filters should be replaced monthly to ensure the most efficiency.Lower the blinds at night - drapes and curtains can serve as insulation to keep heat from escaping through the windows. During the day, open the blinds to let heat from the sun shine through.Insulate your ducts - since warm air flows through the ducts into your home, it is important to make sure that heat stays in the ducts instead of seeping through the bowels of your home. This is especially important in places like the garage, which are typically unheated and can seriously compromise the efficiency of your ducts.
The furnace high limit switch is typically located near the heat exchanger or burner chamber of the furnace.

A high-quality siloxane-based chimney brick sealer is recommended for protecting and preserving the integrity of your chimney.
A fireplace that is back drafting is reacting to a negative pressure being created inside the home by a clothes dryer or leaky furnace supply duct, bath vent or laundry went, water heater or furnace, all of these devices expel indoor air which under certain circumstances will create a negative pressure where the combustion make up air is being supplied by any means possible, this may be the fireplace. Try turning of the dryer or heater or any thing else that expels indoor air and see if it changes, open a window nearby to see if it matters. if not you need to have it inspected by a chimney sweep.
Most of the time there are companies that only do duct cleaning or the chimney sweep companies will do it. The one I had done place bags over each vent and blew through the duct system with a high powered machine.
Furnaces are permanently installed to provide heat to an interior space through intermediary fluid movement, which may be air, steam, or hot water. ... Modern high-efficiency furnaces can be up to 98% efficient and operate without a chimney, with a typical gas furnace being about 80% efficient.
