A downdraft-deflector caps might be better if you have a severe downdraft problem. These caps are generally made of wide, curved metal bands that extend over the chimney to re-direct the wind. In some cases they can even cause a slight increase in chimney draft. Ask your chimney professional to inspect your chimney and determine whether your chimney would benefit from a specialized cap.

Every individual prefer having a clean and smoke free house. Every house ends up getting kitchen smoke which ruins the atmosphere. There are few best Kaff kitchen chimneys that have impressed the market majorly. It is recommended to go with few of the best Hindware kitchen chimneys because they have a good handling rate among high usage situations.

Exterior chimney

Because the chimney is more susceptible to wind-induced draft problems, a chimney that is built outside the house is less likely to be damaged by the elements. Wind pulls heat away from the chimney. This reduces the temperature of the smoke, gasses, and thereby reduces draft. It is not practical to rebuild the chimney at the center of a house. If your chimney is located outside, it is more important that all other components of the system are correct. This includes flue size, liner insulation and chimney caps.

House pressure conditions Sometimes the problem is not with the chimney, but the house. A chimney that is sufficiently tall, properly capped and lined with a cap, and properly installed could cause wind-induced smoking problems.

Example: Wind blowing around an uninsulated house can draw air out from one side, creating a problem in the house’s depressurization. This is similar to how an exhaust fan draws out air. Depending on where the chimney is located, air might be pulled in through the chimney to compensate for air that has been sucked out by wind.
This work is not concerned with the science of wind pressure. The common factor in wind-pressure problems is wind-induced air movement into and out of the home. Here is a brief summary.

1. Wind factors can cause low pressure in the area where the stove is situated. To compensate, air (or smoke) may be drawn into the house through the flue.
2. Wind factors can create high pressure in the area where the stove is situated. This could increase the flow of smoke up the flue.
3. Because less air is being driven into the house, homes that are well-insulated are more likely to experience pressure changes from wind.
This type of problem is not easy to find without the right tools and training. It is best to first address the obvious problems (above), such as chimney height and chimney caps.
If wind-related problems persist, be sure to note the wind direction and intensity as well as whether the stove smokes. Talk to your chimney professional and a venting specialist about the possibility that the problem is in the house.

Smoking during rainy days

Some stoves work fine when it’s wet. If this is the case, you should pay attention to the weather if you are having smoking problems. It’s easy to mistake wind-related problems for rain-related issues. Here are some options if it is the wetness.

Exterior Chimney in Rainy days

Cold, wet. You wouldn’t feel very energetic if you were left out in the rain, cold, and wet. It’s the exact same for chimney drafts in chimneys that are built outside the house. The draft is reduced by the heat emitted from the flue and the gasses. In most cases, the solution is quite simple. First, put a chimney cap over your flue. The cap will prevent most water from entering the flue. Call your chimney professional to arrange for a water repellent to be applied to the exterior brickwork. This will prevent water from getting into the chimney.

No chimney cap. No Chimney Cap. Get a cap

It’s cold inside, but it’s warm outside. Sometimes it’s warmer outside than inside the house on rainy, raw spring and fall days. Draft conditions can be dangerous, especially when the stove is being started. To properly heat the flue, you will likely need to spend more time priming it (see page 60).

Smoke in Other Rooms

For causes and solutions, refer to the section on Smoking In Other Rooms. It is the same for wood stoves and fireplaces.

Mechanical/Maintenance Problems with Wood Stoves

There are many types of wood stoves. However, they are all different. The mechanical problems they encounter are very similar. We will discuss the basic types of wood stoves. The first step to caring for your stove is reading the owner’s manual. This will provide detailed information about your particular model. You can find a label on your stove to identify the manufacturer and model. If this is not available, take a picture of the label and take it with you to the local stove shop. A manual may be available for purchase.
We will be discussing some of the most common problems that you may encounter and how to fix them. This is what we will be covering:

  • Damper malfunction
  • Broken/stuck/loose handles
  • Broken or warped parts
  • Cracked or broken glass
  • Missing or worn gaskets
  • Malfunctioning catalytic combustion engines
  • Poor performance
  • Stove Damper Malfunction

Bypass Damper

Handle moves, damper doesn’t. There are three options if your by-pass damper’s handle is not able to be moved, but the damper remains open or closed. Damper linkage is loose or disconnected The handle is often connected to a lever or bar that presses against the damper blade as you turn it. The damper blade is the plate of metal that opens and closes. There may be several components that lead from the handle to the damper blade. Sometimes one of them might become loose or disconnected.

Broken damper linkage component

A broken part could be caused by someone forcing the damper handle.
The damper blade can become warped, bent, or misaligned. The damper blade can sometimes break, warp, or come out of its correct seat under regular stove use. You have two options in these situations: either hire a chimney professional who will inspect and repair your stove or you can do it yourself. Some damper links are easy to reach, while others are difficult to reach. A stove exploded diagram will prove very useful. If you don’t find one in your owner manual, ask at your local stove shop.
