Chimney considerations should be taken into account while installing a gas stove. Even the most well-constructed stove, boiler, furnace, water heater, and so forth can only function as effectively as the chimney that connects to it. They work together as a unit. The chimney, which draws fresh combustion air into the stove and eliminates flue gases from it, powers the system. 

These emissions can stick to the kitchen’s cupboards, appliances, walls, and ceilings if they are not sufficiently evacuated. Over time, this will result in a dirty kitchen, which is different from what you want. Furthermore, indoor air pollution can result from cooking emissions. Therefore, it is strongly recommended to install a suitable kitchen chimney to keep a clean and healthy kitchen.

What kinds of chimneys are currently on the market?

The market is filled with many kinds of chimneys. Based on where they are situated, chimneys can be divided into four categories: (i) wall-mounted chimneys, (ii) island chimneys, (iii) integrated or built-in chimneys, and (iv) corner chimneys. Based on whether ducts are present or not, kitchen chimneys can be divided into two categories: (i) ducted chimneys and (ii) ductless chimneys. 

The frequency of filter cleaning is another method used to categorize kitchen chimneys. Based on this criterion, there are two types of kitchen chimneys: (i) auto-clean kitchen chimneys and (ii) manual or non-auto-clean kitchen chimneys.

 

1. Wall-mounted chimneys

You must select a wall-mounted chimney if your kitchen counter and gas burner is fixed to the center of the wall. Here, the exhaust hood and duct are fastened to the wall so that your chimney will cover all of your gas.

 

2. Island chimney 

When the gas burner is situated on the kitchen island rather than a wall counter, this design works wonderfully. The chimney is situated directly above your island top and is suspended from above.

3. Corner chimneys 

If your gas stove is situated at the corner of your U-shaped or L-shaped kitchen design, as implied by the system’s name, the kitchen chimney components are fixed to the corner.

4. Built-in chimneys 

Every piece of wall-mounted kitchen furniture has one of these chimneys installed within. The exhaust hood extends down to the bottom of the furniture, and the air duct is concealed therein.

How a chimney works

The idea that hot air rises over cold air is the basis for how chimneys work. There is a pressure difference between the interior of the flue and the room due to the passage of hot gases rising from the fire. A “draught” is created when air is forced into the fireplace; as the air rushes past the fire, it generates the flames. The air rises more quickly and the chimney functions better when the fire’s hotter. The air inside the home is warmer than the outside air, which facilitates air passage through the chimney.

An inefficient chimney will not create enough draught inside the flue, which will prevent enough air from being drawn into the fire to allow it to burn efficiently. 

While it may seem that smoke rises naturally and a chimney “sucks,” it is more appropriate to imagine the weight of dense outside air forcing air into the house and pushing hotter, lighter waste gases up the stack, much the way an air bubble rises in water.

Factors affecting the draught’s quality

The Chimney’s Internal Heat

 For the chimney’s vapours to rise, they need to remain extremely hot. An insulated ceramic liner surrounded by thick masonry or prefabricated insulated components is usually required for the full length of the chimney above, even if a small section of up to 1 meter of uninsulated flue pipe straight from a stove may be permitted.  

Height of the Chimney

The amount of draft produced increases with the height of the chimney stack. The British Standard (BS 8303-1:1994) and Document J both recommend that standard home chimneys and appliances in Britain and Ireland have a straight, smooth, insulated chimney that is approximately 4.7 meters above the appliance. Chimneys that are not as sound will need to be raised to make up for it.

Compared to a chimney placed on an inside wall, an exposed chimney placed on the outside of a home will have more trouble keeping heat inside the flue.

Air Supply

To make up for the volume lost up the chimney, there must be a way for outside air to enter. While air leaking through windows, doors, and other openings might occasionally supply this, installing a specially designed air vent is frequently required. This air can be extracted using an extractor fan or similar fuel-consuming appliance even in a different room.

Route

Every available vertical, straight, smooth path must run from the fire to the chimney terminal. In situations where it is impossible to eliminate bends, they should be very gentle no more than 2x 45º bends and the chimney height should be raised by at least one meter to make up for the discomfort. Ensuring that there is not even the smallest breach that could allow cold air to enter the flue is imperative. The device being utilized must fit inside the flue’s dimensions.
